Life After Death: Astronomers Find a Planet That Shouldn't Exist

The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...

ALMA Digs Deeper Into the Mystery of Planet Formation

An international research team has observed disks around 19 protostars with a very high resolution to search for the earliest signs of planet formation. This survey was motivated by the recent findings that planet formation may be well-underway in the more-evolved proto-planetary disks, but until ...

Starlight and the First Black Holes: Researchers Detect the Host Galaxies of Quasars in the Early Universe

For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big ...

Detection of an Echo Emitted by Our Galaxy's Black Hole 200 Years Ago

An international team of scientists has discovered that Sagittarius A* (Sgr A*), the supermassive black hole at the centre of the Milky Way, emerged from a long period of dormancy some 200 years ago. The team, led by Frédéric Marin, a CNRS researcher at the Astronomical Strasbourg Observatory ...
