An international team of astronomers reports the detection of more than 400 new high-redshift quasars using the Dark Energy Spectroscopic Instrument (DESI). The discovery, published February 3 on the arXiv preprint server, ...
The universe was simply different when it was younger. Recently astronomers have discovered that complex physics in the young cosmos may have led to the development of supermassive stars, each one containing up to 100,000 ...

A group of researchers at Sofia University has found evidence that suggests the reason that a wormhole has never been observed is that they appear almost identical to black holes.
New details surrounding the dark cloud L1527 and its protostar have been revealed by NASA's James Webb Space Telescope. The nebula's vibrant colors, only visible in infrared light, show the protostar is in the midst of gathering ...

An international team of astronomers has analyzed the photometric and spectroscopic observations of a candidate cataclysmic variable known as OGLE-BLG504.12.201843. Results of this analysis suggest that this object is an ...
Astronomers from the Queen's University in Kingston, Canada and elsewhere, have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a mysterious source known as VLA 1623 West. Results of the study, published ...
