Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion of a star. Because supernovae are sudden and unpredictable, they have long been difficult to study, but today, thanks to […]

A new study from the University of Nottingham has explored the use of fuel-free spacecraft propulsion systems and how they could be used in future space missions.

Answers to some of cosmology’s most pressing questions are obscured by simple dust. It concerns the Cosmic Noon, a period of time that began around 2 billion years after the Big Bang, when nearly all galaxies experienced a burst of growth and rapid star formation.

A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the main asteroid belt between the orbits of Mars and Jupiter.

Southwest Research Institute (SwRI) has developed and tested a micrometeoroid and orbital debris (MMOD) detection and characterization system designed for satellites and spacecraft to monitor impacts from space debris. The system provides critical post-impact data, ensuring awareness of an impact even when damage is not immediately apparent.

By analyzing the data from the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Wisconsin-Madison and elsewhere have probed the properties of a massive and old galaxy designated SMILES-GS-191748. Results of the study, published August 7 on the pre-print server arXiv, shed more light on the nature […]

Ursa Major III, the faintest object in our galaxy, orbits the Milky Way at a distance of more than 30,000 light years. Until now, it was considered a dwarf galaxy, thought to consist mainly of dark matter due to its large mass. However, an international team of astrophysicists from the University of Bonn and the […]

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.
