In 2019, telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the scientists could now confirm that the speed of light is constant in vacuum - and not dependent on energy.

Read moreNew telescope detects enormous 'superflare' on nearby star
Astronomers succeeded in detecting 12 stellar flare phenomena on AD Leonis. One of these flares was 20 times larger than those emitted by our own sun, categorizing it a 'superflare'. Subsequent data analysis presents new insight into these explosive phenomena.

Read moreNew study shows colliding neutron stars may unlock mysteries of universe expansion
Researchers have discovered an unusual pulsar where the the masses of its two neutron stars are quite different -- with one far larger than the other. The breakthrough provides clues about unsolved mysteries in astrophysics -- including the expansion rate of the Universe (the Hubble constant).

Astrophysicists have paved the way to unravelling the mystery as to why many supernova remnants that we observe from Earth are axisymmetric (elongated along one axis) rather than spherical.

Two new studies may help to solve one of the biggest mysteries about the dark, icy bodies of the outer solar system: why so many of them don't circle the sun the way they should.

Scientists have identified the binary star Eta Carinae as a new kind of source for very high-energy (VHE) cosmic gamma-radiation. Eta Carinae emits gamma rays with energies up to 400 gigaelectronvolts (GeV), some 100 billion times more than the energy of visible light.
