Using ESA’s Gaia satellite and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers from the Ege University in Turkey and elsewhere have observed a galactic open cluster known as NGC 2506. Results of the observational campaign, published October 7 on the arXiv pre-print server, put more constraints on the properties of this cluster.

On July 2, 2025, NASA’s Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours’ worth of signals that appeared to come from the same source. When scientists compiled this data with signals picked up by multiple other instruments, like the Einstein Probe (EP) Wide-field X-ray Telescope and the Russian gamma-ray spectrometer, Konus-Wind, they found that […]

Explosive volcanic eruptions on early Mars may have transported water ice to equatorial regions, according to a modeling study published in Nature Communications. The authors suggest that these eruptions could have led to conditions that allow these ice deposits to still exist under the surface today, which would expand our knowledge of Mars’s terrain for […]

It’s great to see old astronomical observations come to light. Not only can these confirm or refute what’s known about historic astronomical events, but they can describe what early observers actually saw.

White dwarfs are the compact remnants of stars that have stopped nuclear burning, a fate that will eventually befall our sun. These extremely dense objects are degenerate stars because their structure is counterintuitive: the heavier they are, the smaller they are.

Radio astronomy opens a window onto the invisible universe. While our eyes can detect visible light, countless objects in space emit radiation at much longer wavelengths, in the radio portion of the electromagnetic spectrum. Where visible light gets blocked by interstellar dust, radio waves pass through unrestricted, revealing objects that remain completely invisible to traditional […]

Simulation results highlight how team composition shapes stress, health, performance, and cohesion in long-duration space missions, according to a study published October 8, 2025, in the open-access journal PLOS One by Iser Pena and Hao Chen of the Stevens Institute of Technology, U.S. In particular, team diversity in personality traits may contribute to greater resilience […]

Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between gravity and magnetic fields in some of our galaxy’s most dynamic star forming regions. A team led by Dr. Qizhou Zhang from the Center for Astrophysics | Harvard & Smithsonian used the Atacama Large Millimeter/submillimeter Array (ALMA) […]
