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.

ESA has published an image of Mars’ northern polar cap. It’s the composition of 32 images captured by the the Mars Express space probe’s High Resolution Stereo Camera (HRSC) instrument during as many passages above Mars’ north pole between 2004 and 2010. That mosaic shows the polar cap’s spiral-shaped troughs.

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.

A photograph taken by the Hubble Space Telescope shows the Calabash Nebula, a protoplanetary nebula showing the agony of a low-mass star like the Sun. This nebula is also known by the nickname Rotten Egg Nebula because its study revealed that in the gas surrounding it there’s a high concentration of sulfur, the element that causes the characteristic rotten egg smell.
