The first images from NASA’s new Webb space telescope unveiled this week include a new look at the universe, expanding our view of the galaxy as we know it. The images include a high-resolution “window” to millions of stars through the Milky Way’s dust, a new look at galaxies lightyears away for the first time ...
An international team of astronomers has identified only the second and third examples of a rare type of star system comprising two central stars orbiting each other, known as binary stars, encompassed by a remarkable disk of gas and dust. Michael Poon, a Ph.D. student in the Faculty of Arts & Science’s David A. Dunlap Department ...
Star-forming galaxies are responsible for creating gamma rays that until now had not been associated with a known origin, researchers from The Australian National University (ANU) have confirmed. Lead author Dr. Matt Roth, from the ANU Research School of Astronomy and Astrophysics, said until now it has been unclear what created gamma rays — one of the most energetic ...
A team including Northwestern University astrophysicists has developed the most realistic, highest-resolution 3D simulation of stars being born to date. The result is a visually stunning, mathematically-driven marvel that allows viewers to float around a colorful gas cloud in 3D space while watching twinkling stars emerge. Called STARFORGE (Star Formation in Gaseous Environments), the computational framework is ...
Another win for Einstein’s theory of general relativity. An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in the frequency of the lines in the solar spectrum that is produced when light escapes from the gravitational field ...
Astronomers are closing in on a signal that has been traveling across the Universe for 12 billion years, bringing them nearer to understanding the life and death of the first stars. In a paper on the preprint site arXiv, soon to be published in the Astrophysical Journal, a team led by Dr. Nichole Barry from Australia’s University ...
