In the run up to Christmas, carols fill the air. Many have an astronomical twist, singing of the “Christmas Star” from the story of the nativity. Described in the Gospel of Matthew, the star guided […]

Astronomers have employed the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to observe a mysterious gamma-ray emitting source designated HESS J1857+026. Results of the observational campaign, published December 19 on the pre-print server arXiv, […]

By analyzing the archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected the outflow of a nearby galaxy known as NGC 1266. Results of the new study, presented […]

A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our solar system. Their work, published in The Astrophysical Journal Letters, used NASA’s JWST to reveal an […]

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of these bursts are observed to flash and fade within a few seconds to minutes. […]

Leading X-ray space telescopes XMM-Newton and XRISM have spotted a never-seen-before blast from a supermassive black hole. In a matter of hours, the gravitational monster whipped up powerful winds, flinging material out into space at […]

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed an elliptical galaxy known as NGC 4486B. Results of the observational campaign, published Dec. 16 on the arXiv preprint server, deliver […]

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova—the explosive death of a massive star—at an unprecedented cosmic distance.This post […]

Astronomers have used the Keck Observatory’s DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding was presented […]
