Researchers have found a new way to measure the pull of gravity at the surface of a star. For distant stars with planets orbiting them, this information is key in determining whether any of those planets can harbour life.
It sounds obvious. That's what night is. The sun has set and when you look up at the sky, it's black. Except where there's a star, of course. The stars are bright and shiny.
Astronomers at Yale and Harvard have found a galaxy with a heartbeat—and they've taken its pulse.
Astronomers have discovered a mysterious dwarf planet that is three times farther away than Pluto and believed to be the most distant object in our solar system.
Astronomers from the University of Cambridge have developed a new, highly accurate method of measuring the distances between stars, which could be used to measure the size of the galaxy, enabling greater understanding of ...
We only have one example of a planet with life: Earth. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars. If we find alien life, new questions will arise. ...
Astronomy is entering an exciting new era of exploration.
The ghostly shells of galaxy ESO 381-12 are captured here in a new image from the NASA/ESA Hubble Space Telescope, set against a backdrop of distant galaxies. The strikingly uneven structure and the clusters of stars that ...
Astronomers are a step closer to understanding the evolution of galaxies, thanks to new research that compares the chemical make-up of distant galaxies to those in our own galactic back yard.
Scientists have captured the early death throes of supernovae for the first time and found that the universe's benchmark explosions are much more varied than expected.
