Astronomers Accurately Measure the Temperature of Red Supergiant Stars

Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.

Interactive Map of Earth’s Asteroid and Meteor Impact Craters

Across the history of our planet, around 190 terrestrial impact craters have been identified that still survive the Earth’s geological processes, with the most recent event occurring in 1947 at the Sikhote-Alin Mountains of south-eastern Russia.

The Search For Second Earth

In the search for planets capable of sustaining life, an international research team with members from ETH has taken a significant step forward.

Solar System’s Most Distant Planetoid Confirmed

A team, including an astronomer from the University of Hawai?i Institute for Astronomy (IfA), have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object ever observed in our solar system.

New Theory Explains Possible Origin of the Armageddon-Causing Object That Killed the Dinosaurs

The enduring puzzle: Where did the asteroid or comet originate, and how did it come to strike Earth? Now, a pair of researchers at the Center for Astrophysics | Harvard & Smithsonian believe they have the answer.

Mars Crater Offers Window on Temperatures 3.5 Billion Years Ago

Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.

Researchers Rewind the Clock to Calculate Age & Site of Supernova Blast

Astronomers are winding back the clock on the expanding remains of a nearby, exploded star.

Primordial Black Holes & Search For Dark Matter From Multiverse

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute.

Key Building Block for Organic Molecules Discovered in Meteorites

Scientists from Japan and NASA have confirmed the presence in meteorites of a key organic molecule which may have been used to build other organic molecules, including some used by life.

Inouye Solar Telescope Releases First Image of a Sunspot

The world's largest solar observatory, the U.S. National Science Foundation's Daniel K. Inouye Solar Telescope, just released its first image of a sunspot.

Voyager Spacecraft Detect New Type of Solar Electron Burst

More than 40 years since they launched, the Voyager spacecraft are still making discoveries.

Field Geology at Mars’ Equator Points to Ancient Megaflood

Floods of unimaginable magnitude once washed through Gale Crater on Mars' equator around 4 billion years ago - a finding that hints at the possibility that life may have existed there, according to data collected by NASA's Curiosity rover and analyzed in joint project by scientists from Jackson State University, Cornell University, the Jet Propulsion Laboratory and the University of Hawaii.
