A Danish astronomer and his colleagues have discovered a little space rock that circles the sun in the same orbit as Uranus. This is the first time that astronomers observe a so-called ‘Trojan’ asteroid companion for Uranus.
The first chapter about the creation of our Solar System is now ready to be written. The cloud of molecules from which the Solar System arose consisted of several generations of stardust, say researchers after analysing a meteorite.
The Danish telescope at the La Silla Observatory in Chile has captured a striking image of the star-forming nebula NGC 6559. See the beautiful picture and some of the other pictures from the telescope here.
Using a new computer model, researchers can now see how a solar flare arises and develops. An increased understanding of the gigantic explosions on the Sun will over time give us better space weather forecasts.
