Vaporised crusts of Earth-like planets found in dying stars
Remnants of planets with Earth-like crusts have been discovered in the atmospheres of four nearby white dwarf stars by University of Warwick astronomers, offering a glimpse of the planets that may have once orbited them up to billions of years ago......»»
Star"s disappearance in Andromeda marks the birth of a black hole
Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for months. However,.....»»

Ancient unicellular organism indicates embryonic development might have existed prior to animals" evolution
Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals......»»
Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat crude but helpful fir.....»»
Making farming better for bees: Can we breed crops that produce more nectar and pollen?
Where once there were vast areas of forest and other natural habitats, farmland now covers much of Earth—including 70% of the UK. This transition has helped feed a growing number of people......»»
