What is the origin of water on Earth?
Led by Cédric Gillmann – Université libre de Bruxelles, ULB, funded by the EoS project ET-HoME, a team of researchers demonstrate that the water we are now enjoying on Earth has been there since its formation.
A Martian mash up: Meteorites tell story of Mars’ water history
University of Arizona researchers probed Martian meteorites to reconstruct Mars’ chaotic history. Their findings suggest that Mars might not have had a global magma ocean.
Astrophysicists wear 3D glasses to watch quasars
A team of researchers from Russia and Greece has shown a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3D image by feeding…
Mercury’s 400 C heat may help it make its own ice
It is already hard to believe that there is ice on Mercury, where daytime temperatures reach 400 degrees Celsius, or 750 degrees Fahrenheit. Now an upcoming study says that the Vulcan heat on the planet closest to the sun likely…
First official names given to features on asteroid Bennu
Asteroid Bennu’s most prominent boulder, a rock chunk jutting out 71 ft (21.7 m) from the asteroid’s southern hemisphere, finally has a name. The boulder – which is so large that it was initially detected from Earth – is officially…
Fire from the sky
Researchers find evidence of a cosmic impact that caused destruction of one of the world’s earliest human settlements
What if mysterious ‘cotton candy’ planets actually sport rings?
Some of the extremely low-density, ‘cotton candy like’ exoplanets called super-puffs may actually have rings

Status report: OSIRIS-REx completes closest flyover of sample site nightingale
Preliminary results indicate that NASA’s OSIRIS-REx spacecraft successfully executed a 0.4-mile (620-m) flyover of site Nightingale yesterday as part of the mission’s Reconnaissance B phase activities. Nightingale, OSIRIS-REx’s primary sample collection site, is located within a crater high in asteroid…

The salt of the comet
More than 30 years ago, the European comet mission Giotto flew past Halley’s comet. The Bernese ion mass spectrometer IMS, led by Prof. em. Hans Balsiger, was on board. A key finding from the measurements taken by this instrument was…
Here and gone: Outbound comets are likely of alien origin
Astronomers at the National Astronomical Observatory of Japan (NAOJ) have analyzed the paths of two objects heading out of the Solar System forever and determined that they also most likely originated from outside of the Solar System. These results improve…
Active asteroid unveils fireball identity
At around 1 a.m. local standard time on April 29, 2017, a fireball flew over Kyoto, Japan. Compared to other fireballs spotted from Earth, it was relatively bright and slow. Now, scientists have determined not only what the fireball was,…

Meteorite contains the oldest material on Earth: 7-billion-year-old stardust
The ancient stardust reveals a ‘baby boom’ in star formation
How the solar system got its ‘Great Divide,’ and why it matters for life on Earth
Scientists, including those from the University of Colorado Boulder, have finally scaled the solar system’s equivalent of the Rocky Mountain range. In a study published today in Nature Astronomy , researchers from the United States and Japan unveil the possible…

Collision helped make the Milky Way — and now we know when
Thanks to some astrophysical sleuthing, researchers have pinpointed an early galactic merger that helped shape the Milky Way. The merger — a collision, actually — happened 11.5 billion years ago. That’s when a small galaxy called Gaia-Enceladus slammed into what…
Shocked meteorites provide clues to Earth’s lower mantle
Deep below the Earth’s surface lies a thick rocky layer called the mantle, which makes up the majority of our planet’s volume. While Earth’s mantle is too deep for humans to observe directly, certain meteorites can provide clues to this…
