A color image of Comet 67P has finally been released, revealing that it is… grey. The picture is composed of three images taken by Rosetta's scientific imaging system OSIRIS in red, green and blue filters. In reality, it's even darker, but the image has been brightened enough for us to see the comet's features. » 12/15/14 7:20am 12/15/14 7:20am

The Day After The Comet Landing, Everyone Was Listening To Aerosmith

When the Philae lander touched down on Comet 67P/Churyumov-Gerasimenko, it unleashed a series of Internet memes— most of which were references to the film Armageddon. And within 24 hours, the Aerosmith song "I Don't Want to Miss A Thing" from the movie soundtrack was spiking on Spotify. » 11/26/14 6:30am 11/26/14 6:30am

Images Show Size Of Philae's Comet By Dropping It On Europe's Cities

We've already seen how Comet 67P, current home to the Philae Lander, compares in size to a Star Destroyer, but how does it compare to Earth's own cities? The European Space Agency helpfully improves our understanding of the comet by placing it over satellite photos of various European cities? » 11/15/14 7:00am 11/15/14 7:00am

​Stunning Images Of A Comet's Alien Landscape

In the weeks prior to the Philae landing, the Rosetta spacecraft maintained an orbit around Comet 67P/CG at less than six miles from its surface. The ESA has just released a collection of previously unpublished images taken by Rosetta's navigation camera, revealing the varied and dramatic terrain of a mysterious world. » 11/14/14 8:00am 11/14/14 8:00am

xkcd Animates The Philae Comet Landing—And It's Adorable

Today, we celebrated a monumental achievement in human history: For the first time, we landed an object on a comet. And xkcd creator Randall Munroe celebrated by creating this cartoon flipbook starting three hours before Philae's separation from Rosetta and ending with the landing. » 11/12/14 7:40pm 11/12/14 7:40pm

It's Time For Another Episode In Rosetta And Philae's Adventures!

Here's A Thirty-Year History Of Getting Closer To Comets

Rosetta's lander Philae is warming up to land on comet 67P/Churyumov-Gerasimenko in just a few hours. It will be our first-ever attempt at touching down on a dirty chunk of ice in space. But how close have we gotten to a comet before? » 11/11/14 1:16pm 11/11/14 1:16pm

Comet Trailer Channels The Feeling Of Eternal Sunshine

Check out the trailer for Sam Esmail's Comet. The time-jumping, nebula-cameoing romance story is channeling a lot of the things we loved about Eternal Sunshine of the Spotless Mind. Not saying these movies are similar, but this trailer has a dark/light feel that gets us excited. » 10/27/14 3:57pm 10/27/14 3:57pm

Comet Siding Spring and Mars In One Beautiful Image

We Now Know What A Comet Smells Like

As Comet 67P/Churyumov-Gerasimenko moves closer to the Sun, it becomes more "active," as gases escape from its nucleus through cracks and pores. The Rosetta spacecraft's mass spectrometers have identified the chemical composition of these emissions. If you could smell them, you'd probably wish you hadn't. » 10/23/14 6:20am 10/23/14 6:20am

Here's What Comet Siding Spring Looked Like From Mars

You still have two days if you want to suggest a name for the site where the Philae lander will touch down on Comet 67P/CG. (Currently, the site is simply called Site J.) The only rules are that the name can't be a person, and it should include a brief explanation on why it would be ideal for this historic location. » 10/20/14 10:20am 10/20/14 10:20am

Martian Robots Brace For Close Encounter With Comet Siding Spring

Mars is all set to protect its beloved robots as comet Siding Spring charges past today spewing dust and gas during its close approach to the Red Planet. Meanwhile, everyone from the rovers to Earth-based telescopes will be tracking the comet, learning as much as possible. » 10/19/14 1:09pm 10/19/14 1:09pm

This Rosetta Spacecraft Selfie Is Amazing

The European Space Agency has just released this stunning self-portrait of the Rosetta spacecraft, taken less than ten miles from the surface of Comet 67P/C-G, which is emitting streams of gas and dust into the depth of space. » 10/14/14 1:40pm 10/14/14 1:40pm

Doctored 3D Models Of The Rosetta Comet Are the Best

As the Rosetta spacecraft acquires more precise measurements of the comet 67P/Churyumov-Gerasimenko, scientists are able to create detailed 3D models. Last week, the ESA made that data available for downloading, allowing people to make their own comet replicas—sometimes, with a few creative embellishments. » 10/09/14 11:47am 10/09/14 11:47am

Watch What Will Happen When We Land On a Comet

In the wake of today's announcement that a landing site has been chosen for Comet Churymov-Gerasimenko, the ESA has released a wicked cool, high-def animated sequence depicting the descent of the Philae probe and the deployment of its scientific instruments, starting with a 360-degree survey of its landing site. » 9/15/14 1:07pm 9/15/14 1:07pm

A Stunning Rosetta Selfie, Taken 250 Million Miles Away From Earth

The European Space Agency used one of the cameras on Rosetta's Philae lander to snap this selfie, with comet Churyumov-Gerasimenko visible 31 miles away. (Does that count as photobombing?) The image captures a side of the Rosetta spacecraft and one of its 45-ft-long solar wings. » 9/11/14 7:00am 9/11/14 7:00am

​The Race Begins To Find A Landing Site On Rosetta's Comet

On August 6, the Rosetta probe rendezvoused with Churyumov-Gerasimenko. Now comes the hard part: picking a suitable location for the spacecraft's Philae lander. The site must be chosen soon because, as the comet gets closer to the sun, its icy surface will begin to change. » 8/25/14 1:40pm 8/25/14 1:40pm

Are We There, Yet? The Challenges Of Landing On A Comet

After traveling for more than ten years and four billion miles, Rosetta became the first spacecraft in history to rendezvous with a comet. But, it some ways, the spacecraft's work has only just begun. One of the next challenges will be selecting a safe spot for Rosetta's lander, Philae. » 8/07/14 9:40am 8/07/14 9:40am
