Cheaper than satellites, stratospheric balloons can carry telescopes up to altitudes of 40,000 meters, enabling researchers to observe the Universe. They recently completed a mission over Australia...
Astrophysicist and comet specialist Anny-Chantal Levasseur-Regourd has been involved in the Rosetta project since its early stages. She shares her insight on this extraordinary space mission which is...
Less than four months after the first-ever detection of gravitational waves, a new merger of black holes has been observed by the LIGO-Virgo collaboration.
The Microscope satellite was placed in orbit this April. Its mission: test once more the principle of equivalence, a pillar of the theory of general relativity that postulates that all objects fall...
The Nobel Prize in Physics 2017 has just been awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne for their contribution to the first direct gravitational wave detection as part of the LIGO-...
In order to discover gravitational waves, detectors must be able to distinguish movements as small as one billionth the size of an atom. This major feat of sensitivity has been accomplished and...
