Shortly after astronomers detected asteroid 2024 YR4 on December 27, 2024, they realized it posed no threat to Earth. But it could still impact the moon in 2032. The impact debris could threaten satellites and […]

A new University of Leicester study shows how the uncontrolled growth of a distant supermassive black hole (SMBH) is revealed by the ejection of excess matter as a high velocity wind.This post was originally published […]

A team of astronomers has made a groundbreaking discovery by detecting molecular activity in comet C/2014 UN271 (Bernardinelli-Bernstein)—the largest and second most distantly active comet ever observed from the Oort Cloud.This post was originally published […]

In the vast cosmos, fast radio bursts (FRBs) remain one of the most mysterious astrophysical phenomena ever discovered. These intense, millisecond-duration radio pulses can release in the radio band alone as much energy as the […]

Using NASA’s Chandra spacecraft and ESA’s XMM-Newton satellite, astronomers have investigated the galaxy NGC 7793, searching for supernova remnants (SNRs). As a result, they discovered four new X-ray SNRs in this galaxy. The findings were […]

Very massive stars (VMSs), which typically have masses about 100 times that of our own sun, are critical components in our understanding of the formation of important astronomical structures like black holes and supernovae. However, […]

Scientists using NASA’s James Webb Space Telescope (JWST) have made an exciting discovery about the early universe. They found dozens of small galaxies that played a huge role in transforming our cosmos from a dark, […]

A USC-led research team has created a series of supercomputer-simulated twins of our Milky Way galaxy—which could help scientists unlock new answers about one of the biggest mysteries in the universe: dark matter, the invisible […]

This serene spiral galaxy hides a cataclysmic past. The galaxy IC 758, shown in this NASA/ESA Hubble Space Telescope image, is situated 60 million light-years away in the constellation Ursa Major.This post was originally published […]

An international team of scientists led by astronomers from the University of Wisconsin–Madison has produced the most accurate measurement of the gases swirling around young stars and how their mass changes over time. The discovery […]
