After 286 Days in Space, NASA Astronauts Return to Earth with a Splash
NASA astronauts Butch Wilmore and Suni Williams had been “stuck” at the International Space Station since June 6, 2024, after Boeing’s Starliner, the vehicle they rode to get there, ran into multiple hardware problems
The Square Kilometre Array Releases its First Test Image
The Square Kilometre Array (SKA) remains under construction with completion still a few years away. However, engineers recently provided an exciting preview having installed 1,024 of the planned 131,072 antennas and capturing a test image of the sky. The image covers about 25 square degrees and reveals 85 of the brightest known galaxies in the region. Once fully operational, the complete array is expected to detect more than 600,000 galaxies within this same area!
Astronomers Used Meteorites to Create a Geological Map of the Main Asteroid Belt
More than one million asteroids larger than 1 km exist in the main asteroid belt (MAB) between Mars and Jupiter. Their roots are in a much smaller number of larger asteroids that broke apart because of collisions, and the MAB is populated with debris fields from these collisions. Researchers have created a geological map of the MAB by tracking meteorites that fell to Earth and determining which of these debris fields they originated in.

JWST Cycle 4 Spotlight, Part 3: Supermassive Black Holes and Cosmic Noon
Welcome back to our five-part examination of Webb's Cycle 4 General Observations program. In the first and second installments, we examined how some of Webb's 8,500 hours of prime observing time this cycle will be dedicated to exoplanet characterization and the study of galaxies that existed at "Cosmic Dawn" - ca. less than 1 billion years after the Big Bang.

Dust Obscures Our View of the Cosmos. Now it's Mapped Out in the Milky Way
We see the Universe through a glass darkly, or more accurately, through a dusty window. Interstellar dust is scattered throughout the Milky Way, which limits our view depending on where we look. In some directions, the effects of dust are small, but in other regions the view is so dusty it's called the Zone of Avoidance. Dust biases our view of the heavens, but fortunately a new study has created a detailed map of cosmic dust so we can better account for it.
We Finally Know the Mass of Brand New Neutron Stars
When massive stars explode as supernovae, they can leave behind neutron stars. Other than black holes, these are the densest objects we know of. However, their masses are difficult to determine. New research is making headway.

Astronomers Think They've Found a Reliable Biosignature. But There's a Catch
The search for life has become one of the holy grails of science. With the increasing number of exoplanet discoveries, astronomers are hunting for a chemical that can only be present in the atmosphere of a planet with life! A new paper suggests that methyl halides, which contain one carbon and three hydrogen atoms, may just do the trick. Here on Earth they are produced by bacteria, algae, fungi and some plants but not by any abiotic processes (non biological.) There is a hitch, detecting these chemicals is beyond the reach of current telescopes.
