A team of astronomers have made the discovery of a lifetime that will help answer burning questions on the evolution of stars. The group is led by Evolutionary Studies Initiative member and Stevenson Professor of Physics and Astronomy, Keivan Stassun.

Stassun’s team generated a new model that greatly improved the way stars are measured in 2017.

“Being able to combine all of the different types of measurements into one coherent analysis was certainly key to being able to decipher the various unusual characteristics of this star system,” Stassun said.

The model helps predict the types of planets orbiting distant stars—called exoplanets...

The moment that debris from destroyed planets impacts the surface of a white dwarf star has been observed for the first time by astronomers at the University of Warwick.

They have used Xrays to detect the rocky and gaseous material left behind by a planetary system after its host star dies as it collides and is consumed within the surface of the star.

Published today (9 February) in the journal Nature, the results are the first direct measurement of the accretion of rocky mate...

Scientists at The University of Manchester and The University of Glasgow have today provided more insight into the possibility of establishing a pathway to generate oxygen for humans to potentially call the Moon or Mars ‘home’ for extended periods of time.

Creating a reliable source of oxygen could help humanity establish liveable habitats off-Earth in an era where space travel is more achievable than ever before. Electrolysis is a popular potential method which involves passing electricity through a chemical system to drive a reaction and can be used to extract oxygen out of lunar rocks or to split water into hydrogen and oxygen...

Experiments to simulate Mars’ core may explain the loss of its magnetic field. It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth’s. However, the magnetic field disappeared, and new research may finally be able to explain why. Researchers recreated conditions expected in the core of Mars billions of years ago and found that the behavior of the molten metal thought to be present likely gave rise to a brief magnetic field that was destined to fade away.

Whether it’s due to science fiction or the fact that you can see it with your own eyes from Earth, Mars has captured the imagination of people for centuries...
