A Lancaster University PhD student has measured the optical depth of Saturn's rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings.

How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers from the University of Cambridge have shown how comets could deposit similar building blocks to oth

Data from a NASA mission to map dark matter around galaxy clusters has been saved by a new recovery system designed by scientists at the University of Sydney. The system allowed the retrieval of gigabytes of information, even after communication failed an

A team of European astronomers, co-led by researchers from the Institute of Astronomy, KU Leuven, used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atm

After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months -- a phenomenon astronomers had never seen before, a Cornell-led team reports in new research published Nov.

Given the hostile conditions of extraterrestrial environments, unmanned rovers play a critical role in the exploration of planets and moons. NASA's Mars and lunar exploration rovers have significantly contributed to our understanding of these extraterres

ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like structure of gas and that gas from the star is escaping to t

Optical scientists have found a new way to significantly increase the power of fibre lasers while maintaining their beam quality, making them a future key defence technology against low-cost drones and for use in other applications such as remote sensing.

Gamma-ray flares from blazars can be accompanied by high-energy neutrino emission. To better understand this phenomenon, an international research team has statistically analyzed 145 bright blazars. They constructed weekly binned light curves and utilized

Similar to human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal -- nickel, that is.

Our own Milky Way galaxy is part of a much larger formation, the local Supercluster structure, which contains several massive galaxy clusters and thousands of individual galaxies. Due to its pancake-like shape, which measures almost a billion light years

A ground-breaking new discovery by University of Leeds scientists could transform the way astronomers understand some of the biggest and most common stars in the Universe.
