Webb Captures This Golden Galaxy Cluster in All it's Glory

The NASA/ESA/CSA James Webb Space Telescope Picture of the Month features the brilliant golden galaxies belonging to the MACS J0454.1-0300 galaxy cluster.

The ESA's Euclid Space Telescope Has Discovered A New Comet

The ESA's Euclid space telescope was launched in July, 2026, and its mission is to observe billions of galaxies. The goal is to measure their redshifts over 10 billion years of Universal expansion, to better understand dark matter and dark energy. Surprisingly, the telescope has discovered a brand new comet, now named C/2026 S1 (Euclid).

Achievement Unlocked: Microblazar Confirmed

Researchers have confirmed the existence of the first microblazar. Unlike blazars, which are extragalctic and powered by supermassive black holes, microblazars are inside the Milky Way, and are powered by stellar mass black holes. The microblazar may be the source for the most energetic particles in the galaxy.

New Research Reveals How Long Stays in Space Affects the Human Genome

A new study in Science Advances addresses the pressing questions about how long-duration exposure to microgravity affects the human genome.

Enigmatic Mercury Will Remain A Puzzle Until Someone Sends A Lander

Despite the upcoming Bepi Colombo visit to Mercury, we need a lander mission to fully understand our solar system’s innermost planet.

In the Search for Exoplanets, Some Failures Are A Success

Astronomers used decades of archival data and new radial velocity measurements to search for exoplanets around a neaby binary star, 70 Oph AB. They didn't find any, which can seem like a failure. But in this case, their work only ruled out large, Jupiter-mass planets at certain distances. There could still be Earth-sized planets there, and their precise findings will only fuel a deeper search with more powerful telescopes.

The Flavor of Neutrinos Could Determine How a Large Star Dies

Neutrinos come in three different flavors. A new study finds that neutrino flavor could play a significant role in whether a dying star becomes a supernova or collapses directly into a black hole.
