The discovery of ancient water in a planet-forming disk reveals that some of the water found in comets—and maybe even Earth—is older than the disk’s star itself, offering breakthrough insights into the history of water […]

Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern physics. Because it cannot be fully answered using our current physical worldview, researchers assume […]

A research team from the Yunnan Observatories of the Chinese Academy of Sciences has conducted a study on the binary fraction of blue horizontal-branch (BHB) stars. Their findings, recently published in Astronomy & Astrophysics, provide […]

Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the red planet. By recreating Mars-like conditions in the lab, a team of researchers from NASA […]

An international team of astronomers has discovered the first tidal disruption event (TDE) producing bright radio emission outside the center of a galaxy. The findings are published in The Astrophysical Journal Letters.This post was originally […]

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, […]

By analyzing the available data from various space observatories and ground-based telescopes, Indian astronomers have conducted a long-term multiwavelength study of a changing-look active galactic nucleus (AGN) known as NGC 3822. Results of the new […]

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 […]

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic gravitational-wave background—the sum of many distant sources—or from […]

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 […]
