While astronomers have observed white dwarfs consuming companion stars on numerous occasions, for the first time, they have now observed the consumption of the companion’s helium and not just hydrogen. Plus, galactic alignment, rocket launches including Crew 5, a new Europa image, and a review of the video game “Tinykin”.
Using computer simulations, researchers have pieced together a possible scenario where Titan caused another of Saturn’s moons to break up and become the beautiful ring system we see today. Plus, organic molecules on Mars, the death of the dinosaurs, and a review of Lightyear on Disney+.
Using layers of data from a variety of Martian missions, researchers have developed a machine learning algorithm that identified the actual crater from which a particular Martian meteorite originated. Plus, a radio heartbeat, and our last What’s Up and review of the season.
Using a first-principles approach, researchers have discovered that the differences in the rotational rate of the solar system are due to the inward and outward flow of cations and electrons. Plus, JWST’s first list of observations, a Starlink launch, dinosaurs, raining sand, and a review of episode two of this season’s For All Mankind.
A star cataloged as Gliese 781 is approaching our solar system and in slightly more than a million years from now, will reach the Oort Cloud, likely disrupting the orbits of icy bodies that could head toward Earth. Plus, an Indian launch, Asteroid Day, understanding our ice giants, and a review of Kaiju Preservation Society by John Scalzi.
Using data from the fabulous Gaia mission, researchers have detected four new brown dwarfs as well as several other unusual companions to 25 stars in the Milky Way. Plus, Yellowstone, Earth’s magnetic field, hot Jupiters, and a review of the first episode of The Orville: New Horizons.
