An international team of scientists, including astronomers from the Universities of Leicester, Bath and Warwick, have found evidence for the existence of a ‘hot cocoon’ of material enveloping a relativistic jet escaping a dying star. This research is been published online today (Wednesday 16 January) and in print in Nature tomorrow (Thursday 17 January). A

An international team of scientists is challenging our understanding of a part of Earth’s history by looking at the Moon, the most complete and accessible chronicle of the asteroid collisions that carved our solar system. In a study published today in Science, the team shows the number of asteroid impacts on the Moon and Earth

The universe is about 13.8 billion years old, and its stars are arguably its most momentous handiwork. Astronomers studying the intricacies of star formation across cosmic time are trying to understand whether stars and the processes that produce them were the same when the universe was younger, about half its current age. They already know

Some iron-based superconductors could benefit from a tuneup, according to two studies by Rice University physicists and collaborators. “Our work demonstrates a new design principle for tuning quantum materials to achieve unconventional superconductivity at higher temperatures,” said Rice’s Qimiao Si, the lead theoretical physicist on the studies, which investigate unusual patterns of superconductivity that have

Barnard b (or GJ 699 b) is a recently discovered Super-Earth planet orbiting Barnard’s Star, making it the second nearest star system to the Earth. Although likely cold (-170 degrees centigrade), it could still have the potential to harbor primitive life if it has a large, hot iron/nickel core and enhanced geothermal activity. That was

An image from the international Cassini spacecraft provides evidence of rainfall on the north pole of Titan, the largest of Saturn’s moons. The rainfall would be the first indication of the start of a summer season in the moon’s northern hemisphere. “The whole Titan community has been looking forward to seeing clouds and rains on

A University of Southampton-led project has shown a black hole spinning near its maximum possible rate around its axis. The study, funded by the Royal Society and published in the Astrophysical Journal, comprised an international team of astronomers led by the University and sheds more light on the characteristics of black holes and the environment

Supermassive black holes weigh millions to billions times more than our sun and lie at the center of most galaxies. A supermassive black hole several million times the mass of the sun is situated in the heart of our very own Milky Way. Despite how commonplace supermassive black holes are, it remains unclear how they

Long ago in a galaxy far, far away, fewer galaxies were born than expected — and that could create new questions for galaxy physics, according to a new University of Michigan study. The study examined the satellite galaxies of Messier 94, or M94, a galaxy similar in size to our Milky Way. Researchers have long

New research led by an astronomer at the University of Warwick has found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars. The international team of astronomers used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to obtain high-resolution
