Some Star Just Ripped Apart Halley’s Comet’s Brother

Here’s your daily reminder that the final frontier is ruthless: For the first time ever, scientists have spotted a comet-like object getting torn apart by a white dwarf star. Thankfully, this pugnacious little star — called WD 1425+540 — is located 170 lightyears away from Earth in the constellation Boötes, which may or may not be a piece of IKEA furniture. Read More >>

Rosetta Finds Building Blocks For Life On Comet

Scientists have long debated the possibility that some of the key ingredients for life on Earth were brought to our newly-formed planet by comets and asteroids. A new discovery in the “fuzzy atmosphere” of Rosetta’s comet may lend some credence to this theory. Read More >>

The Last, Desperate Attempt to Contact the Philae Lander Has Probably Failed

Philae, the brave little comet lander that captured our hearts last year, has probably fallen silent for good. After a final, desperate effort to contact the spacecraft over the weekend didn’t pan out, the German Aerospace Agency (DLR) reports that the chances of ever speaking to the probe again are slim — and they’re growing slimmer every day.

Researchers are Launching a Final, Desperate Effort to Contact Rosetta’s Dead Comet Lander

High above us, perched precariously on the cold surface of a comet, there sits one of the most technologically-advanced and singular machines humanity ever sent to hurtle up into space and stick its unlikely landing. And now that it’s there, it’s totally ignoring all our attempts to talk to it. Read More >>

There’s Primordial Oxygen Leaking From Rosetta’s Comet

Comet 67P is full of surprises, from complex organic molecules to miniature space weather systems. Now, in an astronomical first, scientists have discovered molecular oxygen in the space rock’s tenuous atmosphere. And it may be a relic from the birth of the Solar System. Read More >>

This Might Be the Nicest Image Yet of Comet 67P

This stunning view of Comet 67P/Churyumov–Gerasimenko shows what happens when its moves closer toward the Sun: it ejects gas and dust that gets left in its wake. And looks gorgeous, too. Read More >>

The Ultimate Shadow Selfie: Rosetta’s Silhouette On Comet 67P

This new image from the OSIRIS scientific imaging camera of European Space Agency's Rosetta spacecraft reveals two fascinating things. First, we have an incredibly detailed view of the surface of Comet 67P. Second, look at that fuzzy, dark patch at the bottom of the photo— it's the shadow of the spacecraft itself! Read More >>

Rosetta’s Comet Sheds New Light on the Origins of Water on Earth

The spacecraft Rosetta has been circling a "dirty snowball" of a comet since late summer, and now the first scientific paper about this comet has been published. In Science, scientists analysed the comet's water, giving some new clues on how water may have come to Earth. Read More >>

Comet Dust Has Been Hiding Out in Antarctica This Whole Time  

Last month, the European Space Agency landed on a comet 300 million miles away to take samples that could help unravel our solar system's origins. It turns out there are pieces of comets closer to home, too. Scientists have just found comet dust preserved in the frozen reaches of Antarctica. Read More >>

Listen to What it Sounds Like to Land on a Comet

We have sound! The stream of data from Philae, the Rosetta mission's little lander currently hibernating on comet 67, now includes the "thump" it made while touching down. The two-second recording is more scientifically interesting than you might think. Read More >>

Rosetta is Sending Back Intriguing Data on the Origins of Earth’s Water

While we were all worrying about Philae's landing, the spacecraft Rosetta has been patiently circling the comet, doing its own science. And it's just dropped some intriguing results into the big debate over how Earth got its water. Read More >>
