Well, you shouldn’t be. Yes, you’re just one person out of over 7 billion on Earth. Yes, your lifetime — even if you live to be well over 100 — is just a fraction of a flicker of a blink of a tardigrade’s eye (do tardigrades blink?) compared to the 4.6 billion years of the age of the planet. And yes, Earth is only about a third the age of the Universe… which is filled with billions of other galaxies each with stars and planets of their own. Space is just so awfully darn…big.
But, as astrophysicist Neil deGrasse Tyson reminds us in the video above, so are you. So is everyone, in fact. And why? Because we are all a part of it. We’re a part of the Universe… each one of us an inexorably inseparable part of the big picture, a connection between past, present, and future in the most elemental sense possible. As Tyson famously stated once before, “we are in the Universe, the Universe is in us.” And it’s true.
So if you have an admittedly large and heavy ego, put it down for a moment and check out the video. You may come to realize it was weighing you down a bit.
“Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world.”

As soon as you see these images, you’ll probably guess who the photographer is … yes, Thierry Legault. He had less than half a second to capture these incredible shots of the Shenzhou-10 module docked to Tiangong-1 Chinese station transiting across the Sun, and it he did it not only once, but twice, on two consecutive days. Can you see the tiny spacecraft among the sunspots? And keep in mind, there are three taikonauts in these images as well, as the Shenzou has been docked to the Chinese space station module since June 11!
The Tiangong-1 space station is just 10.4 meters (34.1 ft) in length, while the Shenzou 10 is 9.25 meters (30.35 ft) long. This top image is a crop of a full-face view of the Sun, (see the full-face view on Thierry’s website) taken with white light filters by Thierry from southern France on June 16, just after noon UTC. The transit duration was just 0.46 seconds, and Thierry calculated the distance of the spacecraft to observer was 365 km away, and the spacecraft was traveling at 7.4km/s (26,500 km/h or 16,500 mph).
He used a Takahashi TOA-150 refractor, Baader Herschel prism and Canon 6D (1/4000s, 100 ISO).
Below is another solar transit of the two Chinese spacecraft, also taken from Southern France, but the next day, June 17, 2013 at 12:34:24 UTC. This one, in Hydrogen-alpha shows the Shenzhou-10/Tiangong-1 complex in multiple shots over the 0.46 second transit.

For this image, Thierry used his Takahashi FSQ-106, Coronado SM90 double stack, camera IDS CMOSIS 4Mp sensor at 38 fps.
This isn’t the first time Thierry has trained his cameras on the Tiangong-1 – in May of 2012 he captured the tiny space station alone transiting the Sun, and it was dwarfed by a huge sunspot sported by the Sun at the time.
For transits I have to calculate the place, and considering the width of the visibility path is usually between 5-10 kilometers, but I have to be close to the center of this path,” Legault explained, “because if I am at the edge, it is just like a solar eclipse where the transit is shorter and shorter. And the edge of visibility line of the transit lasts very short. So the precision of where I have to be is within one kilometer.”
Legault studies maps, and has a radio synchronized watch to know very accurately when the transit event will happen.
“My camera has a continuous shuttering for 4 seconds, so I begin the sequence 2 seconds before the calculated time,” he said. “I don’t look through the camera – I never see the space station when it appears, I am just looking at my watch!”
He uses CalSky to make his calculations and figure out the timing.
Congrats to Thierry and our thanks to him for sharing his amazing images and skills with Universe Today!

SPACE! The Gallery Show will feature space-themed art such as this piece by Joe Van Wetering. Credit: SPACE! The Gallery Show
Space fans in Los Angeles — and we know, given Mars Curiosity is controlled at the nearby NASA Jet Propulsion Laboratory, that there are lots of you — here’s a neat-looking art show for you to check out in the next month.
SPACE! The Gallery Show will open at Gallery 1988: West today with special NASA guest Bobak Ferdowsi, a systems engineer at JPL who is best known as “Mohawk Guy” — that person with the great haircut being shown on television screens worldwide during the Curiosity landing.
“You guys, I am thrilled to finally share this with you,” wrote organizer Mike Mitchell on his blog. “It’s the first time I’ve ever curated a show, and it’s a theme that I’m very passionate about. Take a gander at the artist list, get yourself pumped up and come to the show. It’s going to be a stellar time.”
The event runs today through Saturday, July 20, closing on the 44th anniversary of the Apollo 11 landing. More information is available on the event’s Facebook page and the gallery’s website.

Following an intense 18 month study to determine if NASA’s New Horizons spacecraft faced potentially destructive impact hazards during its planned 2015 flyby of the Pluto binary planet system, the mission team has decided to ‘stay the course’ – and stick with the originally planned trajectory because the danger posed by dust and debris is much less than feared.
The impact assessment study was conducted because the Pluto system was discovered to be much more complex – and thus even more scientifically compelling – after New Horizons was launched in January 2006 from Cape Canaveral in Florida.
Two years ago researchers using the iconic Hubble Space Telescope discovered two new moons orbiting around Pluto, bringing the total to 5 moons!
It was feared that debris hitting the moons could have created dangerous dust clouds that in turn would slam into and damage the spacecraft as it zoomed past Pluto at speeds of some 30,000 miles per hour (more than 48,000 kilometers per hour) in July 2015.
“We found that loss of the New Horizons mission by dust impacting the spacecraft is very unlikely, and we expect to follow the nominal, or baseline, mission timeline that we’ve been refining over the past few years,” says New Horizons Project Scientist Hal Weaver, of the Johns Hopkins University Applied Physics Laboratory, in a statement.
After both the team and an independent review board and NASA thoroughly analyzed the data, it was determined that New Horizons has only a 0.3 percent chance of suffering a mission destroying dust impact event using the baseline trajectory.

The 0.3 percent probability of mission loss is far less than some earlier estimates.
This is really good news because the team can focus most of its efforts on developing the flyby encounter science plan when New Horizons swoops to within about 12,500 kilometers (nearly 7,800 miles) of Pluto’s surface.
Pluto forms a “double planet” system with Charon, its largest moon. Charon is half the size of Pluto.
But the team will still expend some effort on developing alternative trajectories – known as SHBOTs, short for Safe Haven by Other Trajectories, just in case new information arises from the ships camera observations that would force a change in plans as New Horizons sails ever closer to Pluto.
“Still, we’ll be ready with two alternative timelines, in the event that the impact risk turns out to be greater than we think,” says Weaver.
Indeed the team, led by Principal Investigator Alan Stern, of the Southwest Research Institute is finalizing the encounter plan this month and plans a rehearsal in July of the most critical nine-day segment of the baseline flyby trajectory.
New Horizons will perform the first reconnaissance of Pluto and Charon in July 2015. The “double planet” is the last planet in our solar system to be visited by a spacecraft from Earth.
And New Horizons doesn’t’ stop at Pluto. The goal is to explore one or more of the icy Kuiper Belt Objects (KBO’s) further out in the Solar System.
The team will use the Pluto flyby to redirect New Horizons to a KBO that is yet to be identified.

There are as many as four-hundred billion stars in our galaxy: the Milky Way. And there are more than one-hundred-and-seventy billion galaxies in the observable Universe. Most of those stars have planets, and many of those planets have got to contain useful minerals and fall within their star’s habitable zone where liquid water is present.
The conditions for life are probably everywhere.
But where are all the aliens?
And think about this.
The Universe has been around for 13.8 billion years. Human beings originated 200,000 years ago, so we’ve only been around for 0.01% of the age of the Universe. An intelligent species could arise on any one of those countless worlds, and broadcast their existence to the entire galaxy.
Once a species developed interstellar travel, they could completely colonize our galaxy within a few tens of millions of years; just a heartbeat in the age of the Universe.
So where are they?
As far as we know, Earth is the only place in the Universe where life has arisen, let alone developed an intelligent civilization.
This baffling contradiction is known as the Fermi Paradox, first described in 1950 by the physicist Enrico Fermi.
Scientists have been trying to resolve this mystery for decades, listening for radio signals from other worlds. We’ve only sampled a fraction of the radio spectrum, and so far, we haven’t detected anything that could be a signal from an intelligent species.
How can we explain this?
Maybe we really are the only planet in the entire Universe to develop life. Maybe we’re the first civilization to reach this level of advancement in the entire galaxy. But with so many worlds out there, that really seems unlikely.
Artist impression of an asteroid impact on early Earth (credit: NASA)Maybe civilizations destroy themselves when they reach a certain point. Nuclear weapons, global warming, killer epidemics, and overpopulation could all end humanity. Asteroids could strike the planet and wipe us out. But would this happen to every single civilization? one-hundred-percent of them? Even if ninety-nine-percent of civilizations destroy themselves, we’d still have a couple that made it through and fully colonized the galaxy.
Maybe they’re just too far away, and our signals can’t reach each other. But then, self-replicating probes could traverse those distances and leave a local artifact in every single star system.
Maybe we can’t understand their signals or recognize their artifacts. Maybe, but if aliens constructed a series of artifacts on Earth, I think we’d notice them. The aliens would have experience creating obvious structures.
Maybe they’re just too alien and we just can’t understand them. Maybe we’re too insignificant, and they don’t think we’re even worth talking to. We don’t need to talk to them to know they exist. If they flew through our Solar System, ignoring us, we’d still know they’re around.
Maybe they’re not talking to us on purpose, and we’re really in some kind of galactic zoo. Or aliens have a Prime Directive, and they’re not allowed to talk to us. Again, all the aliens? Not a single one has gotten through and snuck us some evidence? Milky Way. Image credit: NASA
There are many other potential solutions to the Fermi Paradox, but I personally find them all insufficient. The Universe is big, and old, and if extraterrestrial life is anything like us, it wants to multiply and spread out.
Perhaps the most unsettling thought is that something happens to 100% of intelligent civilizations that prevents them from exploring and settling the galaxy. Maybe something good, like the discovery of a transportation system to another Universe. Or maybe something bad, like a destructive technology that has destroyed every single civilization before us.
How do you feel about the Fermi Paradox? How do you resolve the contradictions? Whatever the solution, it’s really fun to think about.
Photographer Graham Gaunt recently spent a week on the beautiful island of St. Agnes, Isle of Scilly during an unusual stretch of clear weather. “I spent every night awake dragging my gear out at dusk and returning to sleep at dawn,” Graham wrote on Vimeo. “No matter how much I thought I had planned out each shot the unraveling of the nights events always brought new and different surprises.”
Thanks to Graham for capturing and sharing his wonderful night views and experiences!

Picture the scene: It’s the not too distant future and humanity has started to construct colonies and habitats all across our solar system. We’re gearing up to take that next big step into the unknown – actually leaving the cozy protection of the Sun’s heliosphere and venturing into interstellar space. Before this future can happen, however, there’s an important thing which is often overlooked in discussions on this subject.
Navigation.
Just as sailors once used the stars to navigate the sea, space travelers may be able to use the stars to navigate the solar system. Except that this time, the stars we’d use will be dead ones. A specific class of neutron stars known as pulsars, defined by the repeated pulses of radiation they emit. The trick, according to a recent paper, may be to use pulsars as a form of interplanetary – and possibly even interstellar – GPS.
Theories and ideas on spacecraft engines are plentiful. Foundations such as Icarus Interstellar keenly advocate the development of new propulsion systems, with some systems such as the VASIMR thrusters appearing rather promising. Meanwhile, fusion rockets are expected to be able to take passengers on a round trip from Earth to Mars in just 30 days, and researchers elsewhere are working on real life warp drives, not unlike the ones we all know and love from the movies.
Interplanetary GPS

But navigation is just as important. After all, space is mind-meltingly vast and mostly empty. The prospect of getting lost out in the emptiness is, frankly, terrifying.
To date, this hasn’t really been a problem, particularly seeing as we’ve only sent a small handful of craft past Mars. As a result, we currently use a messy mishmash of techniques to keep track of spacecraft from here on Earth – essentially tracking them with telescopes while relying heavily on their planned trajectory. This is also only as accurate as our instruments here on Earth are, meaning that as a craft gets more distant, our idea of where exactly it is becomes increasingly less accurate.
This is all well and good when we only have a few craft to track, but when space travel becomes more easily attainable and human passengers are involved, routing everything through Earth will start to become more and more difficult. This is particularly the case if we’re planning on leaving the confines of our home star – Voyager 2 is presently over 14 light hours away, meaning that Earth-based transmissions take over half a day to reach it.
Navigating Earth with modern technology is quite simple thanks to the array of GPS satellites we have in orbit around our world. Those satellites are constantly transitting signals which are, in turn, received by the GPS unit you may have on your car dashboard or in your pocket. As with all other electromagnetic transmissions, those signals travel at the speed of light, giving a slight delay between when they were transmitted and when they’re received. By using the signals from 4 or more satellites and timing those delays, a GPS unit can pinpoint your location on the surface of Earth with remarkable accuracy.

The pulsar navigation system proposed by Werner Becker, Mike Bernhardt, and Axel Jessner at the Max Planck Institute, works in a very similar way, using the pulses emitted by pulsars. By knowing the initial position and velocity of your spacecraft, recording those pulses, and treating the Sun as a fixed reference point, you can calculate your exact location inside the solar system.
Considering the Sun to be fixed this way is technically referred to as an inertial reference frame, and if you compensate for the motion of the Sun through our galaxy, the system still works perfectly well when leaving the Solar system! All you need is to keep track of a minimum of 3 pulsars (ideally 10, for the most accurate results), and you can pinpoint your location with surprising accuracy!
Interestingly enough, the idea of using pulsars as navigation beacons dates all the way back to 1974, notably not long after Carl Sagan had used pulsars to show Earth’s location on the plaques attached to the Pioneer 10 and 11 space probes. If Project Daedalus had ever been constructed, it might have been equipped with a system not unlike the one described here.
Packing for long haul
Becker and his colleagues looked at the different types of pulsar visible in the sky, and picked out a type known as rotation-powered pulsars as the best type to use for a galactic positioning system. In particular, a sub-type of these known as millisecond pulsars are ideal. Being older than most pulsars they have weak magnetic fields, meaning they take a long time to slow down their spin rates – helpful as strongly magnetised pulsars can sometimes change their rotation speed without warning.

With countless pulsars to choose from, the question turns to how you might equip your spacecraft to track them. Pulsars are easiest to spot in either x-rays or radio waves, so there’s a little choice as to which may be better to use. Essentially, it all turns out to be a question of how large your spacecraft is.
Smaller vehicles, more akin to modern spacecraft, would be best off using x-rays to track pulsars. X-ray mirrors, like the ones used in certain orbiting space telescopes are compact and lightweight, meaning that a few could be added for a navigation system without increasing the overall mass of the craft all that much. They may have the minor disadvantage that they may be easily damaged by an x-ray source which is too bright, this wouldn’t be a problem except under some unfortunate circumstances.
On the other hand, if you’re piloting a large space ship between planets or even stars, you would likely be better using radio waves. In radio frequencies, we know a lot more about the way in which pulsars work, as well as being able to measure them with a higher degree of accuracy. The only drawback there is that the radio telescopes you’d need to install on your ship would require an area of at least 150 m². But then, if you happened to be flying a starship, that kind of size probably wouldn’t make much difference.
It’s interesting to bear in mind the way that astronomers frequently use the analogy of pulsars being “like lighthouses” when explaining why they appear to pulse. If we someday find ourselves using them as actual navigation aids, that analogy may take on a whole new meaning!

With more than $1 million in crowdfunded money secured for a public asteroid-hunting space telescope, the ultimate question arises: what about the promised planet chase?
Planetary Resources’ Arkyd-100 telescope reached its $1 million goal yesterday (June 20). But the self-proclaimed asteroid-hunting company has an ambitious aim to add extrasolar planet searching to the list if it can double that goal to $2 million.
The Kickstarter campaign for Arkyd still has 10 days remaining. To keep the funds flowing, the group behind it has released several “stretch” goals if it can reach further milestones:
– $1.3 million: A ground station at an undisclosed “educational partner” that would double the download speed of data from the orbiting observatory.

– $1.5 million: This goal, just released yesterday, is aimed at the more than 20,000 people who signed up for “space selfies” incentive where uploaded pictures are photographed on the telescope while it is in orbit. For this goal, “beta selfies” will be taken while the telescope is in the integration phase of the build.
– $1.7 million: The milestone will be announced if Arkyd reaches 15,000 backers. (It has more than 12,000 as of this writing.)

Over the years, researchers have taken myriad observations of black holes and their environs, but now ESO’s Very Large Telescope Interferometer is giving us the most detailed look of the dust around a black hole at the center of an active galaxy ever obtained. Originally expected to be contained within the ring-shaped torus around the black hole, the observation held a surprise as astronomers discovered that a significant amount of the dust was located both above and below the torus. What can this mean? According to the latest findings and contrary to popular theory, it is possible the dust is being evacuated from the region as a cool wind.
For the last two decades, astronomers have discovered that nearly all galaxies harbor a black hole at their hearts. In many cases, these monsters increase in size by accreting matter from the immediate vicinity. This, in turn, is responsible for the creation of active galactic nuclei (AGN), one of the most energetic objects in the Universe. Surrounding the super-luminous giants are rings of cosmic dust which originate from space – drawn in like water swirling down a dark drain. According to theory, the intense infrared radiation exerted by AGN must have originated from these dusty eddies.
Thanks to the powerful eye of the Very Large Telescope Interferometer (VLTI) at ESO’s Paranal Observatory in Chile, astronomers have now seen something new in a nearby active galaxy cataloged as NGC 3783. While they observed the expected hot dust clocking in at some 700 to 1000 degrees Celsius, what they also observed confounded them… Huge amounts of cooler dust both above and below the main torus.
As Sebastian Hönig (University of California Santa Barbara, USA and Christian-Albrechts-Universität zu Kiel, Germany), lead author of the paper presenting the new results, explains, “This is the first time we’ve been able to combine detailed mid-infrared observations of the cool, room-temperature dust around an AGN with similarly detailed observations of the very hot dust. This also represents the largest set of infrared interferometry for an AGN published yet.”
Is this a black hole teething ring? From their observations, the researchers suspect the newly-discovered dust is flowing outward from the central black hole. This means the wind most likely plays a critical part in the tangled relationship of both the black hole and its surroundings. Apparently the black hole pulls immediate material into it, but the incredible amount of radiation this produces also seems to be pushing it away. Scientists are far from clear as to how these two processes work together, but the discovery of this dusty wind could lead to a better understanding of their evolution.
To get the resolution needed to study the core area of NGC 3783, astronomers needed to use the combined power of the Unit Telescopes of ESO’s Very Large Telescope. Through this union, an interferometer is created – one capable of “seeing” with the equivalent of a 130-meter telescope.
Another team member, Gerd Weigelt (Max-Planck-Institut für Radioastronomie, Bonn, Germany), explains, “By combining the world-class sensitivity of the large mirrors of the VLT with interferometry we are able to collect enough light to observe faint objects. This lets us study a region as small as the distance from our Sun to its closest neighbouring star, in a galaxy tens of millions of light-years away. No other optical or infrared system in the world is currently capable of this.”
What do these new observations mean to the world of astronomy? It might very well change the pattern of how we currently understand AGN. With proof that dust is being expelled by intense radiation, new models must be created – models which include this recent information of how dust can be distributed.
Hönig concludes, “I am now really looking forward to MATISSE, which will allow us to combine all four VLT Unit Telescopes at once and observe simultaneously in the near- and mid-infrared — giving us much more detailed data.” MATISSE, a second generation instrument for the VLTI, is currently under construction.

NASA’s newly produced and absolutely spectacular panorama from the Curiosity mega rover offers armchair explorers back on Earth a mammoth 1.3 billion pixels worth of Mars in all its colorful glory.
And everyone can move back and forth around the interactive panorama and zoom in – with special embedded tools- to your hearts delight in exquisite detail at the ‘Rocknest’ site where the rover spent her first extended science stay in late 2012.
This extra special Rocknest panorama is the first NASA- produced view comprising more than a billion pixels from the surface of the Red Planet.
It offers a full 360 degree panoramic view around the rover encompassing breathtaking vistas of Mount Sharp and the eerie rim of Gale Crater, some 20 miles distant.
Mount Sharp rises 3.4 miles (5.5 km) high and is the target destination. The team hopes Curiosity will arrive at the base of Mount Sharp perhaps late this year or early in 2014.
The ‘Rocknest’ scene was assembled from nearly 900 raw images snapped by three different cameras among the 17 total that Curiosity uses as she trundles across the crater floor in search of the ingredients of life.

The panorama was created by Bob Deen of the Multi-Mission Image Processing Laboratory at NASA’s Jet Propulsion Laboratory, Pasadena, Calif, where the mission is managed on a daily basis.
“It gives a sense of place and really shows off the cameras’ capabilities,” said Deen in a statement. “You can see the context and also zoom in to see very fine details.”

“Rocknest” was a windblown ripple of sand dunes that Curiosity drove to after departing from the touchdown site at ‘Bradbury Landing’ and thoroughly investigated in October and November 2012.
It was at ‘Rocknest’ where the six wheeled rover famously deployed her robotic arm to scoop into the Martian dirt for the very first time and then delivered those first grains to the duo of analytical chemistry labs inside her belly that lie at the heart of Curiosity’s science mission.
Deen assembled the color product using 850 raw images from the 100 mm telephoto camera of Curiosity’s Mast Camera instrument, supplemented with 21 more from the Mastcam’s wider-angle 34 mm camera.
In order to take in the rover itself, the view also included 25 black-and-white raw images from the Navigation Camera on the Mast.
All the images were taken between Oct. 5 and Nov. 16, 2012 while the rover was stationary at Rocknest.

Because the images were captured over many days and at different times of day, the lighting and atmospheric clarity varies – especially in distant views to the crater rim.
Since landing on August 6, 2012, Curiosity has already accomplished her primary goal of finding a habitable zone at Gale Crater with an environment that could once of supported Martian microbial life – at the current worksite at ‘Yellowknife Bay.’

The 1 ton robot is equipped with 10 state-of-the-art science instruments with research capabilities that far surpass any prior landed mission and is in the middle of the 2-year primary mission to the Red Planet.
Meanwhile, Curiosity’s older sister rover Opportunity has also discovered clay minerals and a habitable zone on the opposite side of the Red Planet – details here.
