After combing through NASA’s James Webb Space Telescope’s archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have a previously unseen combination of features.

Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA’s James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou’s College of Arts and Science spotted these strange objects, which seem like one galactic thing but have the unmistakable fingerprints of something else […]

In 1181 AD, a bright “guest star” was observed to linger in the sky for around six months. Nearly 850 years later, the likely remnants of this event were rediscovered and tentatively linked to the 1181 supernova and dubbed supernova remnant (SNR) Pa 30. Yet, this supernova remnant was unique in appearance and researchers have […]

A black hole has shredded a massive star like it was “preparing a snack for lunch,” according to a team of scientists at the American Astronomical Society’s annual meeting (5–8 January).

One of the main questions in exoplanet science concerns M dwarfs (red dwarfs) and the habitability of exoplanets that orbit them. These stars are known for their prolific and energetic flaring, and that’s a problem. M dwarfs are so small that their habitable zones are in tight proximity to them, putting any potentially habitable planets […]

Astronomers from Cardiff University, UK, have employed the Combined Array for Research in Millimeter-wave Astronomy (CARMA) to explore the nearby Andromeda galaxy. Results of the observational campaign, published December 27 on the pre-print server arXiv, yield important insights into the molecular cloud system of this galaxy.
