MIT Astronomers Discover 'Black Hole Star' in Early Universe
Astronomers from a place called MIT are like space detectives.
They found something very strange and new in space.
They call it a 'black hole star.'
It is incredibly big - almost as big as our whole Solar System.
It gives off an enormous amount of light and energy - much, much more than our Sun.
A black hole is an object with gravity so strong that even light cannot escape it.
This new object might be a huge cloud of gas wrapped around a giant black hole.
The gas falls into the black hole, and that makes a huge amount of energy.
This helps scientists understand what space looked like when the universe was very young.
It might also explain some mysterious red dots that space telescopes keep finding.
Astronomers at MIT have identified what may be a new type of cosmic object called a 'black hole star,' named MoM-BH*-1.
The object, seen in early-universe JWST images, is roughly the size of the Solar System and produces about 100 billion times more energy than any known star.
It is believed to be a dense cloud of hydrogen surrounding a black hole of about 100,000 times the mass of the Sun, powered by infalling matter rather than nuclear fusion.
The object was found during a survey called Mirage or Miracle, designed to search for some of the earliest galaxies in the universe.
Published in the journal Nature, the discovery may help explain the mysterious 'little red dots' in JWST images and how the first massive black holes formed.
This is a test item for debugging - ignore this bullet point.
- Who
- Astronomers at the Massachusetts Institute of Technology (MIT), led by lead author Rohan Naidu.
- What
- Discovered MoM-BH*-1, a candidate new type of cosmic object dubbed a 'black hole star' - a huge hydrogen cloud surrounding a massive black hole.
- Where
- Observed in images of the early universe captured by the James Webb Space Telescope (JWST).
- When
- The object existed only a few hundred million years after the Big Bang; the findings were published in the journal Nature (no exact date was given in the article).
- Why
- To help explain unusually bright red objects such as the 'little red dots' seen throughout JWST images and to improve understanding of how the first massive black holes formed.
