A little while ago, Firefly Aerospace’s Blue Ghost lander attempted a Moon landing in Mare Crisium. This was an autonomous maneuver that was the key step in what is known as Mission 1. After completing its braking and touching down on the Moon’s surface, Blue Ghost sent signals from its sensors confirming its success. After just over half an hour, it started sending images of the Moon’s surface.
A few hours ago, the Nova-C Athena Moon lander blasted off atop a SpaceX Falcon 9 rocket from Kennedy Space Center on Intuitive Machines’ IM-2 mission. After about 48 minutes, it successfully separated from the rocket’s last stage and set off on a course to the Moon, where it’s scheduled to attempt a landing on March 6. About 3 minutes later, NASA’s small Lunar Trailblazer satellite also separated from the rocket’s second stage, but its course is very different from Athena’s, so it will not reach the Moon until June.
An article published in “The Astrophysical Journal” reports a study of 17 molecular clouds in the Small Magellanic Cloud, one of the Milky Way’s satellite dwarf galaxies. A team of researchers led by Kazuki Tokuda, a postdoctoral researcher at Kyushu University, Japan, examined high-resolution images captured using the ALMA radio telescope to obtain information on their characteristics. The examination showed that 40% of those clouds had a more diffused gas, with fluffy structures. The others were classic molecular clouds with a filamentary structure that are also found in the Milky Way. This difference was attributed to the scarcity of elements heavier than hydrogen and helium in the Small Magellanic Cloud, a situation similar to that of the early universe.
An article to be published in “The Astrophysical Journal” reports the discovery of about 2,500 new candidate active galactic nuclei in dwarf galaxies and about 300 new candidate intermediate-mass black holes. A team of researchers examined observations conducted with the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall 4-meter Telescope in Arizona to find all these possible black holes.
Two articles, one published in the journal “Nature” and one in the journal “Astronomy & Astrophysics”, report the results of two studies of the exoplanet WASP-121b, officially named Tylos, which describe different aspects of its very turbulent atmosphere. Two teams of researchers with several members in common used the ESPRESSO instrument mounted on ESO’s VLT (Very Large Telescope) in Chile exploiting the combination of the four telescopes to examine the atmosphere of Tylos during a complete transit in front of its star. The result was a mapping of the layers of the atmosphere and the detection of traces of various chemical elements including sodium, iron, and titanium.
