AI learns to model our Universe

Researchers have successfully created a model of the Universe using artificial intelligence, reports a new study.

'Green peas' provide clues to the early days of the universe

It is probable that primordial galaxies triggered the period in the history of the universe known as "cosmic reionization." The Geneva-based astronomer Anne Verhamme has succeeded in demonstrating this by studying green pea ...

Spotting merging galaxies

Over 30 years ago, the Infrared Astronomy Satellite discovered that the universe contained many extremely luminous galaxies, some more than a thousand times brighter than our own Milky Way, but which are practically invisible ...

Virtual 'universe machine' sheds light on galaxy evolution

How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has remained a puzzle for decades, but a University of Arizona-led team of scientists is ...

Visa concerns deter foreign-born PhDs from working in startups

Foreign-born Ph.D. graduates with science and engineering degrees from American universities apply to and receive offers for technology startup jobs at the same rate as U.S. citizens, but are only half as likely to actually ...

Looking for warm dark matter

In the last century, astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize that most of the matter in the universe was not visible. About 84% of the matter ...

Tracer galaxies probe the cosmic background

The universe, perhaps surprisingly, is not comprised of galaxies randomly distributed throughout space; that is, it is not very homogeneous. Instead, its galaxies are clustered into distinct structures, typically gigantic ...
