Galactic crash may have triggered solar system formation

The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s ...

Galaxy formation simulated without dark matter

For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified ...

ALMA discovers massive rotating disk in early universe

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a ...

Fornax A galaxy investigated with AstroSat

Using the AstroSat spacecraft, Indian astronomers have performed an imaging and spectroscopic study of the Fornax A galaxy. Results of the study, published January 13 on the arXiv preprint server, provide more clues on the ...

The Earth formed much faster than previously thought

The precursor of our planet, the proto-Earth, formed within a time span of approximately five million years, shows a new study from the Centre for Star and Planet Formation (StarPlan) at the Globe Institute at the University ...
