If this doesn’t tug at your heart’s space strings, I don’t know what will.
What we’re seeing here is a video made from images captured by NASA’s Juno spacecraft as it flew past Earth on October 9, 2013. This is the first time a video has been made of the Moon orbiting our planet from beyond the Earth-Moon system*, and, in effect, it’s what a future human space traveler would see as they return home.
Yes, I said hexagon. If you haven’t heard, our solar system’s second-largest planet has another curious feature besides its sprawling rings; it’s also in possession of an uncannily geometric six-sided jet stream encircling its north pole — at the heart of which lies a churning hurricane-like vortex over 1,800 miles wide. This hexagon has been known about since the days of Voyager, and now NASA’s Cassini spacecraft has presented us with the highest-resolution look yet at this odd atmospheric phenomenon.
Yesterday sure was interesting. As the astronomical world, from scientists to journalists to enthusiasts alike, watched online in near real time as ISON came within its closest pass of the Sun — in literally ever — the comet, having spent the previous several hours brightening steadily, suddenly went dim as it traveled deep into the Sun’s outer corona. It appeared that it had fallen apart, disintegrating* into a smear of bright particles just as it began to round the Sun. Even as astronomers looked to spot a sungrazing ISON in several of NASA’s Solar Dynamics Observatory’s imaging fields, nothing was to be found, leading many to pronounce the billion-year-old icy visitor from the Oort Cloud dead on arrival.
But then, just as the Twitterverse was lamenting the loss of this year’s most famous comet, something reappeared… and even now, a full day later, they’re still not quite sure what.
Unless you’ve been living in the Oort Cloud you’ve probably heard about the current travels of comet C/2012 S1 (aka ISON) through the inner solar system. Although this soon-to-be “sungrazing” comet was first spotted by astronomers Vitali Nevski (from Belarus) and Artyom Novichonok (Russia) on Sept. 21, 2012, it’s actually been on its way toward the Sun for much, much longer — possibly for the past several million years or so. But on November 28 at 1:38 p.m. EST, as many Americans are sitting down for their Thanksgiving Day dinners here in the U.S., ISON will make its closest pass around the Sun (called perihelion) and, while you won’t be able to see it in the sky at that point (it’s much too close to the Sun right now) our many eyes in the sky will be watching.
There’s been a lot of misinformation passed around the ‘net recently regarding ISON (as seems to be de rigueur whenever something astronomical is occurring) and I can’t stress enough that there’s no reason to be concerned about this comet’s visit. If anything, ISON should be the one worried — there’s still a chance that it won’t survive perihelion intact! In fact, some reports are suggesting that it already has broken up (which as yet has not been confirmed). So to answer some of the most common questions people have been asking about ISON, NASA has shared some video interviews with experts on the subject. Watch them below:
While many skywatchers, scientists, and astronomy enthusiasts around the world wait to see if comet ISON survives its perihelion — that is, its closest pass by the Sun — on Nov. 28, the MESSENGER spacecraft has captured an image of the incoming comet from its position in orbit around Mercury!
The image above, shared today on the MESSENGER website, shows ISON from a distance of 22.5 million miles, and just over 42 million miles from the Sun. At perihelion ISON will come within a scant 730,000 miles of the Sun. Whether or not it survives its Thanksgiving Day encounter has yet to be seen.
It’s a labor of love: using hundreds of thousands of real images taken by NASA’s Cassini, Galileo, Voyager, and other space exploration missions to create a stunning feature-length, high-definition IMAX movie that showcases the beauty of our Solar System on the big screen like never before. This is the achievement of “In Saturn’s Rings,” a project by filmmaker Stephen van Vuuren that’s been years in the making and, based on this latest teaser trailer, beautifully executed.
The footage is made entirely from real photographs using Ken Burns-style photoanimation and multiplane photoanimation. No computer-generated images, painting, cloning, tweening, morphing, texture maps, camera projection or 3D models were used… even the “stargate” titles are made using photos – an 8,000-photo mosaic of all-sky zoomed really fast gives the blurred appearance. And, according to van Vuuren, “a computer is actually not even required to do this – it could all be done exactly using photoanimation techniques from 100 years ago.”
(Of course 100 years ago, touring Saturn with a nuclear-powered spacecraft was only a distant sci-fi dream!)

In theaters summer 2014.
It’s been 15 years since the first piece of what we now know as the International Space Station left the surface of our planet. It was Russia’s Zarya module, launched aboard a Proton rocket on Nov. 20, 1998, and the U.S. followed suit two weeks later with the Unity module sent aboard the shuttle Endeavour. Since then, in what is truly an international effort, the Station was assembled piece by piece until its ultimate ‘official’ completion in 2011 (more research instruments and upgrades have been added since then, of course.)
Orbiting the planet 16 times every day and consistently occupied since 2000, the ISS is not only an invaluable space research lab but also a testament to what we humans can do when we cooperate successfully and focus our energies and abilities toward a common goal, overcoming the challenges of national politics, economic difficulties, and even the barriers of language and culture. It is a lofty achievement, but the work that is done there each day is for the benefit of everyone.
And don’t forget about the view! Our planet is quite beautiful from 260 miles up — and the video above, assembled from time-lapse photos taken from the ISS and edited by David Peterson, shows that wonderfully. See a collection of photos taken from the Space Station here.
“Station is truly an engineering marvel and a testament to what we can accomplish when we all work together. I think one of the most enduring legacies will be the international cooperation we have achieved in building and operating it. It has provided us the framework for how we will move forward as we explore beyond our home planet, not as explorers from any one country, but as explorers from planet Earth.”
– Kennedy Space Center Director Bob Cabana
