The Great Eta Carinae A Eruption was modeled by NASA with help from Hubble and Chandra
NASA teams have modeled in 3D the phenomenon of the Great Eruption of the star Eta Carinae A, in the Eta Carinae stellar system. Having taken place in 1838, the…

These are the most beautiful images ever taken of the center of the Milky Way and its mysterious “radio filaments”
At the heart of the Milky Way, a series of astonishing phenomena is taking place. And thanks to a new map of the region, more detailed than ever, astronomers should…
Here is the most powerful supernova in X-rays ever observed
In 2018, astronomers observed the first supernova explosion of a new class called “the Cow”. Today, a team reports discovering news of these amazing explosions. The brightest ever observed in…
Astronomers have tracked a star’s dying agony until it exploded into a supernova
We had never had the chance to monitor a star to the point of seeing it explode into a supernova. It’s done and at least in the case of SN…
We are passing through a huge gas bubble on the surface of which stars are forming
Our Solar System is navigating through a particularly empty region of space. Surrounded by a local bubble, as astronomers call it. And today, they tell us how this bubble was…
Most powerful X-ray supernova ever seen
In 2018, astronomers observed the first supernova explosion of a new class dubbed “The Cow”. Today, a team reports having discovered news of these astonishing explosions. The brightest ever seen…
The last days of a star before its supernova explosion
We had never had the chance to watch a star to the point of seeing it explode into a supernova. It’s done and at least in the case of SN…
Evolution of life on Earth and supernovae would be closely related
In their quest to understand the origins of life, scientists wonder in particular about the conditions conducive to its emergence. Many hypotheses have already been formulated. And today, researchers are…
Supernova: what is it?
This artist’s impression shows how the material ejected by the SN 1987a supernova is distributed, based on information provided by the Sinfoni spectrograph. © L. Calçada, ESO A supernova is…
