It’s actually remarkably beautiful, and well worth two minutes of your time.*
Assembled from actual photographs taken by astronauts aboard the Space Station, many of them by Don Pettit during Expedition 31 (Don took a lot of photos) this timelapse “The World Outside My Window” by David Peterson ramps up the artistic value by featuring super-duper high definition, smoothed frame transitions and a musical score by “Two Steps From Hell.” (Don’t worry, that sounds scarier than it is.) Even if you’ve seen some of these clips before, they’re worth another go.
After all, there’s no good reason not to be reminded of how beautiful our planet is from space. Enjoy!
*It’s actually two minutes and twenty-eight seconds but I don’t think you’ll mind.
We have another book review and giveaway for you! Just in time for the holidays.
Book review by David Dehetre of Universe Today.
Astronomy Photographer of the Year Collection 2 is a large format, glossy book that covers the Royal Observatory at Greenwich’s annual Astrophotography competition. It covers Earth and Space, Our Solar System, Deep Space, Young Astronomy Photographer, People and Space, Best Newcomer, and Robotic Scope from 2009 to 2012. It also includes a brief how-to primer on astrophotography which, while fine, seemed perfunctory and tacked on.
The book is organized by years and category, with nice double page section breaks with clear, detailed info alongside each image; however, within each year, the categories aren’t delineated, either through typographic means, such as headers or section breaks, or through any indication alongside the images themselves. Usually the category was obvious enough, but it was somewhat confusing at times. Each category contains images by the winner, runner-up, and sometimes one or more ‘highly-commended’ entrants. Some categories also had other images without any designation of why they were included. This could be a typographic omission of some sort, or it could be that they were just additional entrants worthy of inclusion.
I was happy to see the consistently high caliber of work that came out of the competition. There isn’t one image in the book that was less than outstanding. I’ve spent many a night far out in the countryside doing astrophotography as a hobby, and I’ve never come up with an image to compare.
I was also happy to see the competition segmented into subject areas as well as the more expected age/experience categories. This seems to acknowledge that there are different metrics and merit for the broad scope of styles/subjects in astrophotography.
One other point worth mentioning is I found many of the astrophotographers presented were people I was already familiar with, some from Flickr, some from You Tube, and some from periodicals like Sky at Night. I knew these people, and not because they produced and continue to produce great images, but because they are some of the people I learned astrophotography from thus illustrating one of the great underlying aspects of astrophotography: that it is collaborative in nature. I find it heartening that the people who share the most, who help others and communicate, seem to be the ones who do the best work and are the most successful.
I’m of two minds about Astronomy Photographer of the Year though. On the one hand, it’s very well done, beautiful, and stunning: really everything a person could ask for in a book on this subject. At the same time, however, it is trying to document something that is bigger and richer than can be captured in a book.
While the images are flawlessly presented, they lack the backlit brilliance provided by a computer screen, and they aren’t zoomable to view fine details. Many astrophotography images are available on-line at resolutions equivalent to wall-size if they were printed out.
There is also the problem of completeness. While the book is cover-to-cover with great images, in large part it is singular images from outstanding photographers who have dozens or hundreds of stunning images on-line. I found myself flipping a few pages at a time, and then being overcome with a desire to go search out a photographer’s other images. This is perhaps an inevitable outcome of the fact that the competition was conducted on-line (via Flickr), so it’s hard to see it as a negative.
All in all, it really is a fantastic book and I love having it on my shelf that I often randomly flip through to find myself getting inspired, but I don’t think I would have searched it out for that purpose, and I’m not sure who the target customer is supposed to be. It seems incomplete and cursory, especially in the technical details, for someone already involved with the hobby and yet it has a price tag and scope that seems inconsistent with an introductory level book. It would make a great addition to a library collection.

Venus (arrowed) imaged near the waning crescent Moon on August 13th, 2012. (Photo by author).
Here’s a feat of visual athletics to amaze your friends with this week. During your daily routine, you may have noticed the daytime Moon hanging against the azure blue sky. But did you know that, with careful practice and a little planning, you can see Venus in the broad daylight as well?
This week offers a great chance to try, using the daytime Moon as a guide. We recently wrote about the unique circumstances of this season’s evening apparition of the planet Venus. On Friday, December 6th, Venus will reach a maximum brilliancy of magnitude -4.7, over 16 times brighter than Sirius, the brightest star in the sky. And just one evening prior on Thursday December 5th, the 3-day old crescent Moon passes eight degrees above it, slightly closer together than the span of your palm held at arm’s length.
The orientation of Venus and the Moon on Thursday, December 5th as it crosses the local meridian at 3PM EST. Created using Starry Night Education software.
The Moon will thus make an excellent guide to spot Venus in the broad daylight. It’s even possible to nab the pair with a camera, if you can gauge the sky conditions and tweak the manual settings of your DSLR just right.
The best time to attempt this feat on Thursday will be when the pair transits the local meridian due south of your location. Deep in the southern hemisphere, the Moon and Venus will appear to transit to the north. This occurs right around 3:00 PM local. The fingernail Moon will be easy to spot, then simply begin scanning the sky to the south of it with the naked eye or binoculars for the brilliant diamond of Venus. High contrast and blocking the Sun out of view is key — Venus will easily pop right out against a clear deep blue sky, but it may disappear all together against a washed out white background.
The Moon will be at a 10% illuminated phase on Thursday, while Venus presents a slimming crescent at 27% illumination. Though tougher to find, Venus is actually brighter than the Moon in terms of albedo… expand it up to the apparent size of a Full Moon and it would be over four times as bright!

You’ll be amazed what an easy catch Venus is in the daytime once you’ve spotted it — we’ve included views of Venus in the daytime when visible during sidewalk star parties for years.
Due to its brilliancy, Venus has also been implicated in more UFO sightings than any other planet, and even caused the Indian Army to mistake the pair for snooping Chinese drones earlier this year when it was in conjunction with the planet Jupiter. A daytime sighting of the planet Venus near the Moon was almost certainly the “curious star” reported by startled villagers observing from Saint-Denis, France on January 13th, 1589.
Venus can also cast a noticeable shadow near greatest brilliancy, an effect that can be discerned against a fresh snow-covered landscape. Can’t see it? Take a time exposure shot of the ground and you may just be able to tease it out… but hurry, as the waxing Moon will soon be dominating the early evening night sky show!
Another phenomenon to watch for this week on the face of the waxing crescent Moon is known as Earthshine. Can you just make out the dark limb of the Moon? This is caused by the Earth acting as a “mirror” reflecting sunlight back at the nighttime side of the Moon. And don’t forget, China’s Chang’e-3 lander plus rover will be landing on the lunar surface in the Sinus Iridum region later this month on December 14th, the first lunar soft landing since 1976!
The imaginary line of the ecliptic currently bisects the Moon and Venus, as Venus sits at an extreme southern point 2.5 degrees below the ecliptic — in fact, 2013 the farthest south it’s been since 1930 — and the Moon sits over four degrees above the ecliptic this week. The Moon also reached another notable point today, as it reached its most northern “southerly point” for 2013 at a declination of -19.6 degrees. The Moon’s apparent path is headed for a “shallow year” in 2015, after which it’ll begin to slowly widen over its 18.6 year cycle out to a maximum declination range in 2024. It’s a weird but true fact that the motion of the Moon is not fixed to the Earth’s equatorial plane, but to the path of our orbit traced out by the ecliptic, to which its orbit is tilted an average of five degrees.

And speaking of the Moon, there’s another fun naked-eye feat you can attempt tonight. At dusk, U.S. East Coast observers might just be able to pick up the razor thin crescent Moon hanging low to the West, only 23 hours past New. Begin scanning the western horizon about 10 minutes after sunset. Can you see it with binoculars? The naked eye? Chances get better for sighting the slim crescent Moon the farther west you go. North American observers will have a chance at a “personal best” during next lunation in the first few days of 2014… more to come!

Decades after the last man walked on the moon, Apollo astronauts still get a lot of respect. Some of them have been portrayed in Hollywood movies. Many of them willingly, even in their advanced ages, give public lectures and sign autographs. And already, some observers are wondering about the loss to humanity when the last moonwalker dies.
But there is a still a percentage of the population that believes that the astronauts didn’t land on the moon at all. To address this, a couple of experienced hands in filmmaking started a new video series examining and debunking the common conspiracies.
Helming the project is Chris Riley, who produced and directed ‘First Orbit’ as well as two BBC biographies of Neil Armstrong and Richard Feynman, and animator Antony Buonomo, who won an Emmy for his work.
“This Christmas it will be 45 years since the first astronauts reached lunar orbit, and yet conspiracy theories continue to question if the Moonshots ever really happened,” a press release stated.
“The first episode of their Apollo Fact Files has recently been released and Riley is now launching a Kickstarter campaign to raise £5000, which he will use to fund eleven more episodes.”
“Of course, I am trying to debunk the conspiracy theorists, but unlike them, I want people to look at their evidence rationally and critically, and not swallow it whole. It’ll choke you if you do,” Plait wrote at the time.

CAPE CANAVERAL, FL – Today (Dec. 3) marks the 3rd attempt by SpaceX to launch the maiden flight of their significantly upgraded Falcon 9 rocket with the SES-8 telecommunications satellite – following the Nov. 28 ‘Thanksgiving = Spacegiving Day’ scrub due to an aborted 1st stage engine firing in progress.
And the stakes could not be higher for the future of SpaceX – with the firms future launch manifest worth billions of dollars riding on the success of today’s liftoff from Cape Canaveral Air Force Station, Florida.
In an unprecedented launch event for SpaceX, the upper stage engine on the next generation Falcon 9 booster absolutely must restart in flight for a second time in order for the commercial SES-8 payload to be delivered to geostationary transfer orbit (GTO).
Blastoff from Cape Canaveral’s seaside Space Launch Complex 40 is set for 5:41 p.m. EST (2241 GMT).
The Thanksgiving Day launch was aborted by the computers when the Marlin engines thrust failed to build up as fast as planned.
The weather forecast currently shows a 90% chance of favorable conditions at liftoff time according to Air Force meteorologists. The only concern is for winds.

The launch of SES-8 is a milestone marking the first ever attempt by SpaceX to place a satellite into the geostationary orbit replete with numerous high value commercial satellites. This is the doorway to the future profitability of SpaceX.
“I don’t want to tempt fate, but I think it’s going to have a pretty significant impact on the world launch market and on the launch industry because our prices are the most competitive of any in the world,” said SpaceX CEO and chief designer Elon Musk at a prelaunch briefing for media including Universe Today in Cocoa Beach, FL.
For the mission to be declared a success, the upper stage engine must reignite precisely as planned about 27 minutes after liftoff and burn for approximately 1 minute to successfully propel SES-8 into the propel orbit about 33 minutes after launch.

“Whether or not this launch is successful, I’m confident we will certainly make it on some subsequent launch,” said Musk.
“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer, who joined Musk at the prelaunch meeting.
The upgraded Falcon 9 will also be the launcher utilized for the manned SpaceX Dragon capsules launching to the ISS sometime later this decade!
And the very next satellite set for launch by SpaceX later in December – Thaicom 6- is essentially already waiting at the door to the onramp to space.
SpaceX plans a live broadcast of the Falcon 9 liftoff from pad 40 on Cape Canaveral Air Force Station, FL beginning at 5 p.m. EST.
It can be viewed here: www.spacex.com/webcast
The show will feature commentary about the Falcon 9 rocket and launch sequences and the SES-8 commercial satellite from SpaceX corporate headquarters in Hawthorne, CA.
The Falcon 9/SES-8 launch window extends for 86 minutes until 7:07 p.m. EST.
The 3,138 kg (6,918 lbs) SES-8 satellite is a hybrid Ku- and Ka-band spacecraft that will provide TV and communications coverage for the South Asia and Asia Pacific regions.
This mighty new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level that rises to 1.5 million pounds as the rocket climbs to orbit
The Merlin 1-D engines are arrayed in an octaweb layout for improved efficiency.
Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.
The next generation Falcon 9 is a monster. It measures 224 feet tall and is 12 feet in diameter. That compares to 13 stories for the original Falcon 9.
Stay tuned here for continuing SpaceX & MAVEN news and Ken’s SpaceX launch reports from on site at Cape Canaveral & the Kennedy Space Center press site.

Sunlight can do fun things in space. For example: this recent picture of Titan (a moon of Saturn) shows sunlight hitting the moon’s surface as well as a southern vortex, just visible in the shadows of the picture.
“The sunlit edge of Titan’s south polar vortex stands out distinctly against the darkness of the moon’s unilluminated hazy atmosphere,” NASA stated. “The Cassini spacecraft images of the vortex led scientists to conclude that its clouds form at a much higher altitude — where sunlight can still reach — than the surrounding haze.”
Titan has intrigued scientists for decades, since the Voyager spacecraft first revealed it as a world socked in by orange haze. Cassini dropped off a lander on the surface, called Huygens, which took pictures on the surface in 2005. Besides that, the orbiter has revealed a lot about lakes, rain and other features of the moon in the year since.
Cassini has been orbiting the moon since 2004 and is still busily producing science, but there are concerns that NASA’s budget situation could cause the agency to shut down operations on the still-healthy spacecraft. There are no other missions to Saturn or Titan booked yet, although scientists do have intriguing ideas for exploration.

Astrophotographer Damian Peach has wowed us with his images of Comet ISON the past few months. Here’s a montage of some of his best images from September 24 to November 15.
“This may well be my final word on it.” Damian said via email, “but here it is growing in brightness on approach to its best in mid-late November.”
And while it appears there’s a ghost of ISON out there with a blob of dust in the latest views from the Sun-studying satellites, it won’t give us the views we had hoped for. But its been a fun experience the past few months, watching what unfolded. Thanks for bringing us along for the ride with your images, Damian!

We’ve seen some great views from space of erupting volcanoes, like Pavlov, Shiveluch, and Nabro. While most of the views from space look straight down in a in a nadir view, this photo was taken from the International Space Station with an oblique or sideways viewing angle. This provides a three-dimensional-type view, similar to what might be seen from an airplane instead of a flattened view that looks straight down. This image was taken by an astronaut when the ISS was located over a ground position more than 1,500 kilometers (900 miles) to the southwest of the Kamchatka Peninsula in the far eastern part of Russia. The Kliuchevskoi volcano is just one of 160 volcanoes in this region, with 29 of the 160 being active.
NASA says the plume—likely a combination of steam, volcanic gases, and ash—stretched to the east-southeast due to prevailing winds. The dark region to the north-northwest is likely a product of shadows and of ash settling out. Several other volcanoes are visible in the image, including Ushkovsky, Tolbachik, Zimina, and Udina. To the south-southwest of Kliuchevskoi lies Bezymianny Volcano, which appears to be emitting a small steam plume (at image center).
These volcanic peaks are an eye-catching landmark from orbit. Here’s an image of the same region taken by astronaut Chris Hadfield earlier this year:

Comets can spend billions of years out in the Oort Cloud, and then a few brief moments of terror orbiting the Sun. These are the sun grazers. Some survive their journey, and flare up to become the brightest comets in history. Others won’t survive their first, and only encounter with the Sun.
