An article accepted for publication in the journal “Astronomy & Astrophysics” reports the results of the observation of a new activity of the supermassive black hole at the center of the galaxy cataloged as SDSS J133519.91+072807.4 and called “simply” SDSS1335+0728. A team of researchers used observations conducted with various instruments to observe an increase in this galaxy’s brightness. This already led to its inclusion among those with an active galactic nucleus at the end of 2019.

The WL20S system in a combination of ALMA and Webb observations

At the 244th Meeting of the American Astronomical Society, a study was presented of what turned out to be a pair of stars inside the WL20 group, cataloged as WL20S. The authors of this study combined observations conducted with the ALMA radio telescope and the James Webb Space Telescope to obtain the information necessary to establish that in that system there are two young stars, and not one as astronomers thought, which formed between 2 and 4 million years ago. Both stars are surrounded by disks of materials in which there could be planets forming and parallel jets of materials emitted by the two stars.

An article published in the journal “Nature Geoscience” reports the detection of frost on volcanoes in the Tharsis region on Mars. A team of researchers used data obtained from two ESA space probes, the ExoMars mission’s TGO and Mars Express, which made it possible to discover for the first time the presence of frozen water on the Martian surface at the red planet’s equator. In the calderas of the big volcanoes of Tharsis, blue deposits that can be attributed to water ice were spotted which are present only in the morning and then evaporate a few hours later.

A few hours ago, Boeing’s CST-100 Starliner Calypso spacecraft docked with the International Space Station’s Harmony module, completing the first leg of its Boe-CFT (Boeing Crewed Flight Test) mission which began with the launch just over 24 hours earlier. After checking that the pressure was correctly balanced, the hatch was opened to allow Butch Wilmore and Suni Williams to enter the Station and begin their mission, which will last about a week.

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 fourth 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. In this case, however, they are prototypes with the Super Heavy identified as Booster 11 and the Starship identified as Starship 29 or Ship29 or simply S29. Each test leads to new changes to the vehicles’ systems and this happened after the third test conducted on March 14, 2024, as well. The vehicles still don’t meet the safety requirements needed to conduct controlled landings, so plans continue to call for the test to end with the splashdown of both vehicles.
