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.

A New Study Challenges Assumptions About The Origins Of Earth's Water

Water, water everywhere, but how on Earth did it get here? Many scientists believe that Baby Earth formed dry and was later soaked by an onslaught of extraterrestrial impacts. But a new study challenges that view, arguing that our planet has had water from the start. In fact, we have have inherited it from the tiny grains of dust that spawned the Solar System.

Cool Visualisation Lets You See Philae Bounce And Tumble As It Lands On A Comet

It was one year ago today that the Philae Lander bounced, spun, and tumbled across the surface of Comet 67P/Churyumov-Gerasimenko. To commemorate the historic event, the European Space Agency has released an animated video chronicling the lander’s chaotic landing.

Get Ready For 'Spooky', The Halloween Asteroid!

Video: On All Hallow’s Eve in the US, an asteroid dubbed “Spooky” will make its closest approach to our planet. Hurtling along at an impressive 126,864km/h, the 400m-wide object poses no threat to Earth…or does it? This Gizmodo video explains Spooky’s story.

Here's Our First Glimpse Of The Rosetta Comet's Dark Side

The Rosetta spacecraft has taken hundreds of stunning photographs of Comet 67P/Churyumov-Gerasimenko over the past year, but a portion of the comet was obscured due to its odd seasonal shifts. Now, thanks to a special camera aboard Rosetta, scientists have created a sketch of its elusive dark side.

Scientists Discover Weather On Rosetta's Comet

Earth’s favourite comet is chock full of surprises. The latest? Weather, of sorts. According to research published this week in Nature, Comet 67P has a small weather system driven by an intense day-night cycle.

Astronomers Want To Watch Comets Slam Into Distant Planets

If a massive comet struck the Earth, the oceans would boil and the air would catch fire (don’t worry, this isn’t about to happen). But to alien astronomers studying our planet from afar, humanity’s brutal demise would look like nothing more than a faint flicker of light. If we could detect such impacts on distant worlds, we might learn a lot about their star systems.

We Found The Building Blocks Of Life On A Comet

Last week, a slew of scientific papers told the story of comet lander Philae’s bumpy touchdown, comet 67P’s surprisingly fluffy surface, and — most exciting — the discovery of life’s building blocks there. We haven’t found life. But we may have found part of life’s origin story, buried on this icy rock.

What Would Happen If A Massive Comet Struck The Sun?

Humans, dark and disturbed creatures that we are, love to imagine what would happen if a massive comet struck the Earth. But what if a giant ice rock flung itself into the Sun? A team of astronomers did the maths to figure out what would happen.
