ESO telescope reveals what could be the smallest dwarf planet yet in the solar system
Astronomers using ESO's SPHERE instrument at the Very Large Telescope (VLT) have revealed that the asteroid Hygiea could be classified as a dwarf planet. The object is the fourth largest in the asteroid belt after Ceres, Vesta and Pallas. For the first time, astronomers have observed Hygiea in sufficiently high resolution to study its surface and determine its shape and size. They found that Hygiea is spherical, potentially taking the crown from Ceres as the smallest dwarf planet in the solar system. (2019-10-28)

Dust from a giant asteroid crash caused an ancient ice age
About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and new species evolved with the new temperatures. The cause of this ice age was a mystery, until now: a new study in Science Advances argues that the ice age was caused by global cooling, triggered by extra dust in the atmosphere from a giant asteroid collision in outer space. (2019-09-18)

Stardust in the Antarctic snow
The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team with significant involvement from the Technical University of Munich (TUM) has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood. (2019-08-20)

(2019-06-11)

ESO contributes to protecting Earth from dangerous asteroids
The unique capabilities of the SPHERE instrument on ESO's Very Large Telescope have enabled it to obtain the sharpest images of a double asteroid as it flew by Earth on May 25. While this double asteroid was not itself a threatening object, scientists used the opportunity to rehearse the response to a hazardous Near-Earth Object (NEO), proving that ESO's front-line technology could be critical in planetary defense. (2019-06-03)

A family of comets reopens the debate about the origin of Earth's water
Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans. Now, however, an international team, including CNRS researchers, has found that one family of comets, the hyperactive comets, contains water similar to terrestrial water. The study relies in particular on measurements of comet 46P/Wirtanen carried out by SOFIA, NASA's Stratospheric Observatory for Infrared Astronomy. (2019-05-23)
