A map of the outer suburbs of the Andromeda galaxy finds that its rotating disk of stars is three times bigger than previously measured.
Although previously suspected, astronomers now have clear evidence that gamma ray bursts come in separate varieties.
New computer model finds possible reason behind an ancient bombardment of the Moon, plus neatly explains how the giant planets came to travel their current paths.
Recent research shows that the solar speeds can be accurately measured by observing a relatively deep layer of the Sun’s atmosphere – far beneath where the winds are though to originate.
The star's behavior is similar to that of our Moon, which turns just fast enough to keep one face always pointing at the Earth.
