Bursts of Methane may have Warmed early Mars

Findings may help in search for life in the universe. The presence of water on ancient Mars is a paradox. There’s plenty of geographical evidence that rivers periodically flowed across the planet’s surface. Yet in the time period when these waters are supposed to have run – 3 to 4 billion years ago – Mars should have been too cold to support liquid water. Researchers from the Harvard John A. Paulson School of Engineering and Applied Science (SEAS) suggest that early Mars may have been warmed intermittently by a powerful greenhouse effect...

Can the Donut-Shaped Magnet ‘CAPPuccino submarine’ hunt for Dark Matter?

Scientists at IBS CAPP are prototyping haloscopes - machines that hunt for dark matter. Haloscope have very strong magnets. Helix-shaped magnets (solenoid magnets, on the left) are commonly used in dark matter experiments. CAPP scientists are also investigating the possibility of using donut-shaped magnets, technically known as toroidal magnets, and nicknamed this device "CAPPuccino submarine".

First big-picture look at Meteorites from before Giant Space Collision 466 million years ago

Today's rare meteorites were once common

466 million years ago, there was a giant collision in outer space. Something hit an asteroid and broke it apart, sending chunks of rock falling to Earth as meteorites since before the time of the dinosaurs. But what kinds of meteorites were making their way to Earth before that collision? In a new study in Nature Astronomy, scientists have tackled that question by creating the first reconstruction of the distribution of meteorite types before the collision. They discovered that most of the meteorites we see today are rare, while many meteorites that are rare today were common before the collision.
