This newly released ALMA image shows a newborn star enshrouded in dust. This intriguing image may look like a collection of colored blobs, but it…
New research from the Harvard-Smithsonian Center for Astrophysics reveals that the nearby star Proxima Centauri shows signs of a 7-year activity cycle. In August astronomers…
Hubble observations have revealed a string of super-hot blobs, each with a temperature of more than 17,000 degrees Fahrenheit, being ejected from a dying star….
Astronomers have discovered a striking spiral-arm structure in the disc of gas and dust around the young star Elias 2-27. The structure is made up…
This newly released image shows a protoplanetary disc surrounding the young star Elias 2-27. This beautiful image, captured with the Atacama Large Millimeter/submillimeter Array (ALMA)…
Using the Atacama Large Millimeter/submillimeter Array, a team of astronomers reveal the first hot core to be found outside the Milky Way. A hot and…
Using the Hubble Space Telescope, an international team of astronomers has been able to study stellar evolution in real time. Over a period of 30…
Using data from Chandra, astronomers have the strongest evidence to date that violent stellar mergers produce pencil-thin jets. This result has implications for estimating the…
