Space and astronomy news
Why do we explore? Is it the desire to break through boundaries, or to probe the perimeters of possibilities? With his lightning-fast mind, self-professed wonder junkie Jason Silva can quickly list all the great quotes about space exploration and why it is important for the human species to explore; and he does it in this new video from his “Shots of Awe” series on You Tube.
Strap in and enjoy the fast ride that is Jason Silva!

In honor of this today’s Wave at Saturn and The Day the Earth Smiled events, celebrating images to be taken of Earth from Saturn, here’s a wonderful movie showing highlights from Cassini’s exploration of the giant planet, its magnificent rings, and fascinating family of moons.
Assembled by Fabio Di Donato in memory of astrophysicist, author and activist Margherita Hack, who passed away June 29 at the age of 91, this video is an impressive tour of the Saturnian system — and a truly stunning tribute as well.
“She made me love the stars,” Fabio wrote.
This video shows a selection from more than 200,000 pictures taken by the Cassini spacecraft around Saturn’s rings in a period between 2005 and 2013. RAW images were processed to PNG thanks to the Vicar-to-PNG procedure provided by Jessica McKellar.
The music is Jazz Suite No.2: VI Waltz 2 by Shostakovich, performed by the Armonie Symphony Orchestra.
As always, you can see the latest images and news from the Cassini mission here, and find out how your photo is going to be taken from 900 million miles away (and also 60 million miles away from Mercury!) here.

Want a “you are there” view of today’s EVA that took place outside the International Space Station? Take a look at this great video of astronaut Chris Cassidy getting a ride on the station’s Canadarm-2 to make repairs and prepare for a new Russian laboratory. There are several great “over the shoulder” views during this short highlight video.
During their 6-hour and 7-minute spacewalk, Cassidy of NASA and Luca Parmitano of the European Space Agency worked on replacing a failed communications receiver, relocating grapple bars for future spacewalks and stringing cables for the when the Russian laboratory module arrives later this year.
The Ku-band communications receiver replaces one that failed last December. There was already a redundant backup system now in use, and this new one will become the backup.
The new Russian lab, called Nauka, will replace the Pirs airlock. It is scheduled to launch on a Proton rocket booster late this year, although the flight could be delayed a bit until early next year as because of assembly delays in Russia.
This spacewalk was the first of two in as many weeks for the duo. They will again venture outside the Quest airlock on July 16 for more upgrades and repairs. This was Parmitano’s first spacewalk, and he has now become the first Italian astronaut to walk in space. Old pro Cassidy has now been on five spacewalks, and this was the 170th spacewalk in support of space station assembly and maintenance.
At 2:38 UTC Tuesday morning (local time) a Russian Proton-M heavy lift rocket carrying three GLONASS navigation/positioning satellites exploded shortly after lifting off from the pad at Baikonur Cosmodrome. The event was captured on a live Russian news feed, seen above.
No word yet on whether there were any injuries or not according to NASASpaceflight.com, no casualties have been reported but the Proton rocket debris may have landed near another pad used by ILS (International Launch Services) — a U.S./Russian joint venture for commercial launches.
According to Anatoly Zak at RussianSpaceWeb.com, “since the emergency cutoff of the first stage engines is blocked during the first 42 seconds of the flight to ensure that the rocket clears the launch complex, the vehicle continued flying with its propulsion system firing practically until the impact on the ground.”
Reminder: space travel is (still) hard.
Update: Watch another view of the failed launch below:
The shockwave at 1:01… yikes.
It’s been 9 years (to the day, in fact) since the Cassini spacecraft first entered orbit around Saturn and ever since it has been sending a steady stream of incredible images from the ringed planet back to Earth, bridging the 900-million-mile distance with countless wonders and groundbreaking discoveries. The views Cassini has provided us of Saturn and its family of moons are unparalleled and unprecedented, but something one could remain in want of is the element of motion: Cassini’s cameras are designed to capture still images, not true video, and thus most of our best views of Saturn are static shots.
That’s where filmmaker Stephen van Vuuren and his current project, “In Saturn’s Rings,” comes in.
An award-winning filmmaker, musician, and photographer (and self-confessed übergeek) from South Africa, Stephen van Vuuren has spent the last several years compiling hundreds of thousands of images acquired by Cassini — as well as other exploration spacecraft — into a single high-definition feature film, one that will allow viewers to experience the beauty, grandeur, and reality of the Solar System like never before.
“In Saturn’s Rings” (formerly “Outside In”) is slated for release in IMAX theaters, planetariums, and museums in the spring of 2014 — and the first official teaser trailer is below, released today. Check it out (or visit the YouTube page to watch in original, eye-melting 4k high-resolution):
“‘In Saturn’s Rings’ is a film that’s both personal and universal, experimental and sincere, science and spirit , non-narrative and documentary. The goal is to use large screen imagery, synchronized to powerful but moving music, to create an experience for those who see it, hear it and feel it.”

This is one film that I’ll be eagerly looking forward to over the next few months, without a doubt!

Can you get good astrophotography shots from within a city? Astrophotographer Bruno Letarte has proved you can capture stunning shots of both city and night sky and turn them into a beautiful timelapse. Last fall we featured a timelapse by Bruno taken at the dark sky site of the South African Large Telescope (SALT), but he said his latest project of shooting among the city lights was a “real learning experience.”
“It was a completely different challenge, much trickier than shooting a perfect dark sky, where you find your optimal exposure time and stick to it for everything,” Bruno told Universe Today via email. “Different objects and different focal lengths, lights in the foreground, moving cars, etc. Many sequences had to be decided on the spot with no time to really think it through.”
He captured various objects (Moon, Sun, planets, comets) either rising or setting against a nice city landscape — with light pollution and all – and all taken with an entry level enthusiast camera.
“It was a real learning experience for me to shoot in these various conditions. It’s also an invitation to the general public to look up in their night sky to see what’s up there, even in a city,” Bruno added. “And for the amateur photographer out there, I’ve included the tech details and comments for each sequences with a few seconds of flashing text.”
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.”

We’ve oohed and ahhed many times over the handiwork of Randy Halverson and his Dakotalapse timelapse videos and imagery of the night sky. He may have outdone himself with his latest timelapse, called “Horizons.” Randy shot the footage from April – October 2012, mostly in South Dakota, but also some at Devils Tower in Wyoming.
“Growing up in South Dakota the landscape itself can be beautiful at times,” Randy says, “but that doesn’t compare to what the sky can do, especially at night.” Not only is the imagery absolutely breathtaking, but the accompanying music is an original called “I Forever” by Bear McCreary (The Walking Dead, Defiance, Battlestar Galactica, etc) his brother Brendan McCreary and his band Young Beautiful in a Hurry.
There’s a four-minute version below, but also available on Vimeo On Demand is a full 30-minute feature . Enjoy!!
The lead image and this one below are recent images from Randy that he has posted on Flickr.

Photographer and storm chaser Mike Olbinski has captured some incredible storm footage over the years (such as this apocalyptic haboob in Arizona in 2011.) But his latest timelapse was something he’s been chasing down for over four years: a rotating supercell. Mike lives in Arizona, where that type of storm doesn’t happen. But he regularly visits the US Central Plains and said on his website that he’s been hoping to capture footage of “clouds that rotate and look like alien spacecraft hanging over the Earth.”
To quote Mike again, “Boy, did we find it.”
On June 3, 2013 he and his team were following storms near Booker, Texas. “We chased this storm from the wrong side (north) and it took us going through hail and torrential rains to burst through on the south side. And when we did…this monster cloud was hanging over Texas and rotating like something out of Close Encounters.”
Watch it below:
It never turned into a tornado, thankfully.
The timelapse was shot on a Canon 5D Mark II with a Rokinon 14mm 2.8 lens.
Mike says:
It’s broken up into four parts. The first section ends because it started pouring on us. We should have been further south when we started filming but you never know how long these things will last, so I started the timelapse as soon as I could.
One thing to note early on in the first part is the way the rain is coming down on the right and actually being sucked back into the rotation. Amazing.
This video has gone viral, and unfortunately some sites aren’t crediting Mike as the photographer. But just to be clear, this is a Mike Olbinski original!

The season for noctilucent “night-shining” clouds is arriving in the northern hemisphere, when wispy, glowing tendrils of high-altitude ice crystals may be seen around the upper latitudes, shining long after the Sun has set. Found about 83 km (51 miles) up, noctilucent clouds (also called polar mesospheric clouds) are the highest cloud formations in the atmosphere. They’ve been associated with rocket launches and space shuttle re-entries and are now thought to also be associated with meteor activity… and for some reason, this year they showed up a week early.
Noctilucent clouds (NLCs) form between 76 to 85 kilometers (47 to 53 miles) above Earth’s surface when there is just enough water vapor to freeze into ice crystals. The icy clouds are illuminated by the Sun when it is just below the horizon, after darkness has fallen, giving them their night-shining properties. This year NASA’s AIM spacecraft, which is orbiting Earth on a mission to study high-altitude ice, started seeing noctilucent clouds on May 13th.
“The 2013 season is remarkable because it started in the northern hemisphere a week earlier than any other season that AIM has observed,” reports Cora Randall of the Laboratory for Atmospheric and Space Physics at the University of Colorado. “This is quite possibly earlier than ever before.”
The early start is extra-puzzling because of the solar cycle. Researchers have long known that NLCs tend to peak during solar minimum and bottom-out during solar maximum — a fairly strong anti-correlation. “If anything, we would have expected a later start this year because the solar cycle is near its maximum,” Randall says. “So much for expectations.”
Read more on the NASA AIM page here, and watch the Science@NASA video below for the full story. (Also, check out some very nice NLC photos taken last week in the UK by Stuart Atkinson at Cumbrian Sky.)
