The Calvera pulsar and the diffuse emission region object of this study, seen in X-rays

An article published in the journal “Astronomy & Astrophysics” describes a candidate supernova remnant that was associated with the pulsar nicknamed Calvera. A team of researchers from the Italian National Institute for Astrophysics (INAF) and the University of Palermo, led by Emanuele Greco of INAF, conducted observations and analyses of a decidedly unusual pair, as finding it approximately 6,500 light-years above the Milky Way’s galactic plane was surprising.

It was the afternoon in the USA when SpaceX conducted a new flight test of its Super Heavy rocket and Starship prototypes, launched from its base in Boca Chica, Texas. This is the 10th test involving the entire system of Elon Musk’s company, which is supposed to revolutionize space travel with an unprecedented transport capacity and being totally reusable. They are advanced prototypes with the Super Heavy identified as Booster 16 and the Starship Block 2 identified as Starship 37 or Ship37 or simply S37.

A little while ago, the SpaceX Dragon 2 spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its CRS-33 (Cargo Resupply Service 33) mission, also referred to as SPX-33. After almost 12 minutes, it separated successfully from the rocket’s last stage and went en route. This is the 33rd mission for the Dragon/Dragon 2 spacecraft to resupply the International Space Station with various cargoes and then return to Earth, again with various cargoes.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” (MNRAS) reports the discovery of a rare hierarchical quadruple system, which was cataloged as UPM J1040−3551 AabBab. A team of researchers used observations conducted with ESA’s Gaia space probe and NASA’s WISE space telescope, followed by spectroscopic detection and analysis, to identify this quartet consisting of a pair of red dwarfs and a pair of brown dwarfs. This relatively young system may offer new information, especially about brown dwarfs, objects halfway between planets and stars.
