University of Warwick astronomer co-authors new study in Nature Astronomy that proposes a solution to long-running question of how white dwarf stars generate magnetic fields…
A group of astronomers has discovered 8 millisecond pulsars located within dense clusters of stars, known as “globular clusters,” using South Africa’s MeerKAT radio telescope….
The universe we see is only the very tip of the vast cosmic iceberg. The hundreds of billions of galaxies it contains, each of them…
15 years of radar measurements provide new information on planet’s spin, internal structure. Venus is an enigma. It’s the planet next door and yet reveals…
Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA’s Chandra X-ray Observatory, could be a major step…
An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018….
