The low carbon levels are particularly interesting, as previously discovered “pristine” or metal-poor stars generally ...

The most ‘pristine’ star in the universe discovered by astronomers - Red giant star J0715-7334 is 20,000 times purer than the ...

Even before the first stars lit up the Universe, the Cosmos was not the cold place most researchers once imagined. New results suggest that the so-called cosmic “dark ages,” the muted era between the ...

So how many stars are there? Given all of the above, astronomers estimate that the Milky Way contains around 100 billion ...

Look up at the sky on a clear night, and you’ll see thousands of stars – about 6,000 or so. But that’s only a tiny fraction of all the stars out there. The rest are too far away for us to see them.

Massive stars do not live long. There are several candidates for the biggest star in the universe. One of them, VY Canis Majoris, is over 1,500 times the width of the sun. If it were placed in our ...

Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This was discovered by an international team of 70 astronomers led by ...

Led by principal investigator Michael Zemcov, an assistant professor in RIT’s School of Physics and Astronomy and Center for Detectors, the experiment aims to better understand extragalactic ...

The early universe was already warm before reionization, revealing that the first stars did not flicker on in an icy cosmos.

Pulsars could be helping scientists distinguish between gravitational waves caused by supermassive black hole collisions and ...
