The star, named AS0039, is located in the Sculptor dwarf galaxy around 290,000 light-years from the solar system. This stellar remnant has the lowest concentration of metal, particularly iron, of ...

It is what is known as a starburst galaxy due to its remarkably high rate of star formation. In fact, for every star born in the Milky Way, 10 burst into existence in M82. The reason for this much ...

Observations of stellar movements in galaxies and the cosmic microwave background — an afterglow of the Big Bang — indicate that about 80% of all matter in the universe is dark matter, a ...

It now turns out that our Galaxy is home to a stellar structure uniquely made of stars with extremely low metallicity, with a heavy element content 2,500 times lower than that of the Sun.

Two of them are stellar oddities known as a Wolf-Rayet star. Dubbed Kýklos and WR16, these are massive celestial bodies, perhaps 25 times heavier than the Sun, near the end of their relatively ...

Astronomers have detected an extremely unusual star that they believe is a stellar fossil, or remnant, of one of the universe's very first stars. The star, named AS0039, is located in the Sculptor ...

The vast realm probed by radio astronomers is one invisible to the naked eye, and even most kinds of telescopes. Now, thanks to the latest advances in radio observatories, scientists are uncovering an ...
