<p>The discovery was made using the NIRSpec instrument on the James Webb Space Telescope (JWST) as part of the RUBIES survey.

<p>"It was totally unexpected to find old stars in a very young universe.

<p>The researchers found signs of 'old' stars by analysing the intensity of wavelengths emitted by the objects. The stars were hundreds of millions of years old compared to a relatively young universe.&nbsp;</p>

Discovery of ancient stars and massive black holes in young galaxies challenges cosmic theories

<p>Scientists have discovered what they call “Milky Way's most massive" black hole yet. To put its size into perspective, it’s at least 33 times bigger than the Sun and located 2,000 light years away from us. Astronomers at the European Southern Observatory's Gaia mission spotted the gigantic black hole when they noticed a star wobbling as it orbited the area.</p>

<p>The black hole has been named Gaia BH3. It’s the second-closest black hole to Earth and sits in the Aquila constellation. Gaia is a Latin word which means “the eagle”.</p>

<p>"No one was expecting to find a high-mass black hole lurking nearby, undetected so far," said Pasquale Panuzzo, an astronomer from the National Centre for Scientific Research at the Observatoire de Paris. "This is the kind of discovery you make once in your research life," the astronomer added.</p>

<h2><strong>How are black holes formed?</strong></h2>

<p>Black holes are formed when stars reach the end of their lives. Most of these stars inflate, lose mass and cool down to become “white dwarfs” but others lose less mass that don’t contain heavy elements. These stars are called ‘metal-poor stars’ and instead of becoming white dwarfs, they collapse in on themselves and form a black hole.</p>
