The supernova remnants 1E 0102.2-7219

An article published in the journal “Nature Astronomy” describes the study of the supernova remnants identified as 1E 0102.2-7219 in the Small Magellanic Cloud. A team of researchers led by Frédéric Vogt used the MUSE instrument installed on ESO’s VLT to observe a large ring of gas in that system that is slowly expanding into the depths of several other gas filaments that are quickly moving away, leaving behind a neutron star in the center.

An article published in the journal “Classical and Quantum Gravity” describes the reconstruction of the map of magnetic fields generated after the Big Bang in the “cosmic neighborhood”. A team of researchers used an algorithm called BORG (Bayesian Origin Reconstruction from Galaxies), developed to work on large-scale structures, to data from the 2M++ galaxy catalog to calculate how these magnetic fields should look like today within a radius of 300 million of light years around the Earth.

Icarus (MACS J1149+2223 Lensed Star 1)

An article published in the journal “Nature Astronomy” describes the observation of the most distant star and therefore also the oldest observed so far, nicknamed Icarus, about 9 billion light years from Earth. A team of researchers exploited a double gravitational lensing effect that magnified the image of the star, which was called MACS J1149+2223 Lensed Star 1 but for that reason it’s simply called Lensed Star 1 (LS1). That effect made it become bright enough to be detectable by the Hubble Space Telescope.

A few hours ago the SpaceX Dragon spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its CRS-14 (Cargo Resupply Service 14) mission, also referred to as SPX-14. After just over ten minutes it separated successfully from the rocket’s last stage and went en route. This is the 14th mission for the Dragon spacecraft to resupply the International Space Station with various cargoes and then return to Earth, again with various cargoes.
