Particle acceleration in the Centaurus A localized

Superposition of the Emission to Centaurus A in different wavelength ranges. The light blue Ellipse describes the emission model of Centaurus A in a high-energy gamma radiation, as it was calculated from the H. E. S. S. scientists.

Stars haunted by huge magnetic spots

to the non-mobile version 01 June 2020, 11:26 p.m. With the help of telescopes from the European Southern Observatory (ESO), astronomers have discovered huge spots on the surface of extremely hot stars that are hiding in star clusters. Not only are these stars plagued by magnetic spots, some also experience superflare events, high-energy explosions that […]

A rare “ring of fire” galaxy discovered 11 billion light-years away

Astronomers have recently immortalized a rare galaxy. Described as “a circle of cosmic fire”, this ring galaxy is located 11 billion light years from the Solar System. If you are not familiar with ring galaxies, you will be amazed to discover Hoag’s object (image below): a splendid silver circle studded withstars, carrying in its heart […]

Mysterious fast radio bursts reveal where missing material is hidden

Missing matter … Astronomers have been looking for it for almost 30 years. In vain. But today, based on another mystery of our Universe, rapid radio bursts, they have finally got their hands on it. From the start, she hid in the intergalactic space. For many years, astronomers are concerned about a mystery: part of […]

ESO instrument discovers earth’s blackest hole

This artistic representation shows the orbits of the objects in the triple system HR 6819. This system consists of an inner double star system with a star (orbit in blue) and a newly discovered black hole (orbit in red) as well as a third object, another star, in one larger orbit (also in blue). The […]

CHEOPS ready for science operations

Image of CHEOPS of the star named HD 88111. The star is located 175 light years from Earth in the constellation Hydra, and it is not known whether a planet orbits around it. CHEOPS took a picture of the star every 30 seconds for 47 consecutive hours. (Image: ESA / Airbus / CHEOPS Mission Consortium) […]
