An article published in the journal “Astronomy & Astrophysics” describes the observation of a small group of galaxies attracted by the galaxy cluster Abell 2142 and approaching it a trail of very hot gas was created. A team of researchers led by Dominique Eckert, now at the German Max Planck Institute for Extraterrestrial Physics, used NASA’s Chandra X-ray space observatory to detect the emissions from a sort of tail that extends over a million light years.
An article published in the journal “Nature” describes the discovery of a pulsar-type neutron star with a very strong magnetic field that emits a jet of materials. A team of researchers used the Very Large Array (VLA) radio telescope to study the neutron star cataloged as Swift J0243.6+6124 and simply called Sw J0243 discovering an anomaly because according to the formation models for jets of material a pulsar with such a strong magnetic field shouldn’t be able to emit them.
A little while ago the HTV-7 “Kounotori” spacecraft was captured by the International Space Station’s Canadarm2 robotic arm, operated by Drew Feustel with the assistance of Serena Auñón-Chancellor. The Japanese space cargo ship, which blasted off last Saturday, carries a huge amount of supplies and experiments. After its capture, it will take a little while before the HTV-7 starts getting moved to its berthing location on the Harmony module.
An article published in the journal “Nature Geoscience” reports the evidence of the presence of dust storms in the equatorial regions of Titan, the largest of Saturn’s moons. A team of researchers analyzed data collected by the Cassini space probe to find those evidence that make Titan the third object in the solar system where dust storms were discovered after the Earth and Mars. This is a further similarity between Titan and the Earth.
An article to be published in the “Astrophysical Journal Letters” reports the discovery of the exoplanet HD 39091c, the first identified thanks to NASA’s TESS space telescope. It’s a super-Earth with a radius of 2.14 ± 0.04 the Earth’s and a mass estimated at 4.82 ± 0.85 the Earth’s. It’s very close to its star, which is a little larger than the Sun, with a year that lasts just over 6 Earth days.
