The mystery of why massive galaxies existed in the early universe may now have been solved. New research shows that the galaxies were formed as a result of a collision of galaxies and the subsequent explosive formation of stars.
The recent discovery of a millisecond pulsar orbited by two white dwarfs challenges current theories of their formation. A new semi-analytical model may help explain the formation of this unique triple system.
Danish scientists are trying to develop a ’recipe’ for habitable planets. They hope to be able to predict where in our galaxy we should look for potentially habitable planets. The odds of finding life on other planets are extremely high, they say.
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.
