Dust is everywhere — not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a nuisance…
Astronomers are observing star-forming regions in our galaxy with NASA’s flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments…
The spots on the surface of the Sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven…
A team of more than 200 researchers, including Penn State Department of Astronomy and Astrophysics Assistant Professor Jason Wright and led by Louisiana State University’s…
At first glance, it would seem to be impossible to look inside a star. An international team of astronomers, under the leadership of Earl Bellinger…
A team of U.S. astronomers studying the star RZ Piscium has found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting…
Using ESO’s Very Large Telescope, astronomers have for the first time directly observed granulation patterns on the surface of a star outside the Solar System…
A new Chandra image shows the location of several elements produced by the explosion of a massive star. Supernova remnants and the elements they produce…
ALMA reveals a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae, helping astronomers to better understand…
New research from Notre Dame lends support to an existing theory of how binary star system AR Scorpii emits energy. Astronomers studying the unique binary…
Astronomers have mapped the gas distribution and velocities in the atmosphere of the red supergiant star Antares, delivering insights into the fate of a star….
New research from the Harvard-Smithsonian Center for Astrophysics reveals that the correlation between a galaxy’s stellar mass and star formation rate is a tight one….
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)…
