The research team ran a supercomputer-based ‘fight club’ involving simulated large asteroid collisions […]

Artist’s interpretation of the explosion of a recurrent nova, RS Ophiuchi. This is a binary star in the constellation of Ophiuchus and is approximately 5,000 light-years away. It explodes roughly every 20 years when the gas flowing from the large star that falls onto the white dwarf reaches temperatures exceeding […]

This image shows an all-sky mollweide map of the quadrupole in the distribution of galaxy spin directions. In this image, the different colors mean different statistical strength of having a cosmological quadrupole at different points in the sky.

A new, Yale-led study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies — and the supermassive black holes within their cores — aggregate into clusters, these clusters create a volatile, highly pressurized environment. Individual galaxies falling into […]

Astronomers using ESO telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters, called extreme horizontal branch stars. This image shows an artist’s impression of what one of these stars, and its giant whitish spot, might look like. The spot is bright, takes up […]

Discovery Sheds New Light on Famous Einstein Ring Social distance science made possible with public W. M. Keck Observatory and NASAarchive data. Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Mauankea in Hawaii […]

This image shows the sparkling centerpiece of Hubble’s 25th anniversary tribute. Westerlund 2 is a giant cluster of about 3000 stars located 20,000 light-years away in the constellation Carina. Hubble’s near-infrared imaging camera pierces through the dusty veil enshrouding the stellar nursery, giving astronomers a clear view of the dense […]

It took the discovery of a new celestial phenomenon and entirely new telescope technology. Diligence, technological progress, and a little luck have together solved a 20-year mystery in the cosmos. CSIRO/Alex Cherney J. Xavier Prochaska is a professor of Astronomy & Astrophysics at the University of California, Santa Cruz. Jean-Pierre […]
