Rosetta's Comet Is Even Weirder Than We Thought

If you thought a comet that contains the building blocks of life and creates its own weather couldn’t get any more interesting, think again. Scientists finally have a theory as to why comet 67P — also known as Rosetta’s comet — has two distinct lobes. It’s actually two distinct comets, which break up, orbit one another and smash together again and again for all of cometary eternity. And despite how strange this relationship sounds, it may be a lot more common than we thought.

Hubble Just Caught A Close-Up View Of What Flying Into An Active Comet Looks Like

Comets brush by us all the time, but they’re usually not close enough for us to catch anything more than a glimpse as they streak through the sky. But, thanks to one very close comet, Hubble just got an incredible insider view.

A Mysterious Object From Earth's Distant Past Has Returned

A first-of-its-kind space rock filled with pristine material from the formation of the Earth itself has returned to the inner solar system, after billions of years in the cosmic boondocks. And it could help us piece together our planet’s origin story.

Sugar That Created Life Could Have Come From Interstellar Space

The case that we’re all just highly organised lumps of space sweets keeps getting better. For the first time, scientists have created ribose — the key sugar underlying RNA — in laboratory conditions simulating the cold, radiation-blasted vacuum of outer space.

Something Just Slammed Into Jupiter

Astronomers have captured video evidence of a collision between Jupiter and a small celestial object, likely a comet or asteroid. Though it looks like a small blip of light, the resulting explosion was unusually powerful.

Rosetta's Comet Inspired These Paintings, And The Materials Used To Create Them

Millions of people around the globe were enthralled when the European Space Agency’s Rosetta spacecraft successfully landed on Comet 67P/Churyumov-Gerasimenko in November 2014. Artist Ekaterina Smirnova was one of them — so much so that she has created an entire series of giant watercolour paintings inspired by the comet.

We Finally Know What's Inside Rosetta's Comet

Scientists have long pondered what lies beneath the surface of comet 67P, but a study out in Nature this week has the answer: dust. Lots and lots of dust. I was hoping for space gremlins, but to planetary scientists this result is almost as exciting.

The ESA's Latest Image From Rosetta Shows Off A Rugged Surface 

Image Cache: Rosetta is still orbiting Comet 67P/Churyumov-Gerasimenko, and it’s beamed back an impressive image showing off the comet’s surface. It’s rugged and beautiful.

New 3D Shape Model Shows The Rosetta Comet In Unprecedented Detail

The ESA has released a new 3D shape model of Comet 67P/Churyumov-Gerasimenko. This model integrates the latest images taken by the Rosetta spacecraft, and includes previously unknown features. It can be used for 3D printing or graphical representations.

That Supposed Alien Megastructure May Actually Be A Swarm Of Cometary Fragments

An oddly dimming star located 1500 light-years from Earth is causing all sorts of commotion in the scientific community, leading some to speculate that it may be some sort of alien megastructure. A new analysis of infrared data suggests a more natural explanation.
