Here’s Where ESA’s Philae Will Make the First Ever Landing on a Comet

The long-awaited deployment of the Philae lander, currently “piggybacked” aboard ESA’s Rosetta spacecraft orbiting the nucleus of Comet 67P/Churyumov-Gerasimenko, will occur in less than a month and we now have our best look yet at the area now green-lighted for touchdown. The picture above, made from two images acquired by Rosetta’s OSIRIS imaging instrument, shows a 500-meter circle…

Spacecraft’s Selfie is Photobombed by a Comet

In-situ spacecraft “selfies” are always a treat and this one is awesome times two: taken by the Philae lander piggybacked onto ESA’s Rosetta, it shows one of the spacecraft’s 14-meter-long (46-foot) solar arrays glinting with reflected sunlight while off in the distance is the “rubber duckie” Comet 67P/Churyumov-Gerasimenko!

Space Mountain!

Where do you suppose this rocky, jagged peak is located? Sierra Nevada? The French Alps? The Himalayas? Actually this craggy mountain is located much, much farther away than any of those Earthly ranges (although it’s currently getting closer by the day) – this is a peak on the 4-km-wide nucleus of Comet 67P/Churyumov-Gerasimenko, imaged by…

Get Ready for Rosetta’s Rendezvous with a Comet!

How exciting – it’s almost time! After over ten years of travel ESA’s comet chaser Rosetta is mere hours away from its first rendezvous with the 4-km-wide comet 67P/Churyumov-Gerasimenko! We’ve all been seeing better and better images of the comet since it first became visible to Rosetta a few months back, with the past couple…

Comet, Dead Ahead! ESA’s Rosetta Is Only Days Away From Its Target

She’s almost there! After a decade of soaring through the inner solar system ESA’s Rosetta spacecraft (and Philae lander) are now on final approach to Comet 67P/Churyumov-Gerasimenko, the ultimate goal of the mission. On August 6 the spacecraft will approach within 100 km of the comet and attempt to establish orbit — if successful, Rosetta…

Rosetta’s Comet Looks Like a Giant Peep

Surprise!* Rosetta’s target comet 67P/C-G is apparently a contact binary, with a nucleus made of two objects joined at a point and held together by gravity based on the latest images in from the spacecraft. Tumbling through space on its orbit around the Sun, it bears an uncanny resemblance to… a giant marshmallow Peep. (The…

Telescope Tag-Team Reveals an Asteroid Beast’s Beauty

Telescope twin powers: ACTIVATE! Form of… an asteroid? Okay, so the telescopes involved aren’t twins — one is a giant 70-meter dish in California’s Mojave Desert and the other is a 305-meter behemoth high in the Puerto Rican rain forest — they did combine their powers to image the passing asteroid 2014 HQ124 on June 8…

Fireball Explodes Over Russia… Again

Why does Russia seem to get so many bright meteors? Well, at 6.6 million square miles it’s by far the largest country in the world plus, with dashboard-mounted cameras being so commonplace (partly to help combat insurance fraud) mathematically it just makes sense that Russians would end up seeing more meteors, and then be able to…

Hubble Eyes Mars-Bound Comet

Comet Siding Spring won’t hit Mars on October 19 but it will come really, really close: 86,000 miles, or just a bit over 1/3 the distance between the Moon and Earth. That’s like having a bullet from a sniper positioned a mile away knock your hat off! (Given that you were the target of a…

Rings Discovered Around an Asteroid

We all know that Saturn is encircled by a system of rings, and perhaps you also know about the fainter rings around Uranus, Jupiter, and Neptune. But today, ESO astronomers have revealed a surprising discovery: there are also rings surrounding the asteroid 10199 Chariklo, a small, distant world orbiting the Sun far beyond Saturn. This makes 250-km-wide Chariklo the fifth…

Hubble Watches As an Asteroid Crumbles

Our solar system is an active place, and that is no better illustrated than with these recent observations by the Hubble Space Telescope of asteroid P/2013 R3 breaking apart — and it’s not even disintegrating in Earth’s or any other planet’s atmosphere, but rather as it travels through space 480 million km away from the…
