An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes the evidence gathered of the existence of a bridge of stars between the two Magellanic Clouds, the two dwarf galaxies satellite of the Milky Way. An international team led by astronomers from the University of Cambridge used data collected by ESA’s Gaia space probe to determine that the bridge is composed not only of gas but also of stars that are old and were stripped from their galaxies.

NASA released an image of the solar flare occurred on January 21 captured by the GOES-16 satellite that the agency runs with NOAA using the Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) instrument. It’s specifically aimed to observe the Sun and monitor phenomena such as solar storms, which can have consequences on the activity of satellites but also of power plants and other human activities.

An article published in the journal “Nature Astronomy” describes the discovery of the first white dwarf pulsar, an object so far only hypothesized but never found. A team of researchers from the British University of Warwick identified it in the AR Scorpii (AR Sco) System, composed of a red dwarf and the white dwarf pulsar that a rotation period of just under two minutes.

NGC 6334 and NGC 6357 (Image ESO)

ESO has released one of the largest astronomical images created thanks to the VST (Very Large Telescope Survey Telescope) which includes two cosmic clouds of gas and dust, NGC 6334 and NGC 6357. Because of their shapes, they’re also known respectively with their popular names as the “Cat’s Paw Nebula” and the “Lobster Nebula”.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research that provides an explanation for an astronomical mystery dating back to the 1970s. A team of researchers of the Anton Pannekoek Institute for Astronomy in Amsterdam led by Jakob van den Eijnden discovered a gap in the accretion disk of the binary system MXB 1730-335, known as Rapid Burster for its rapid and discontinuous X-ray flashes.
