Jakarta, CNN Indonesia —
Hottest place in universe that has ever been recorded is quasar 3C273, a bright region around black hole supermassive with a temperature of about 10 trillion degrees Celsius.
The sun is the hottest object in our Solar System. However, its temperature is small when compared to the hottest place in the universe.
“I think the right answer is supermassive black holes, especially supermassive black holes that grow, which means the black hole is eating gas,” said Daniel Palumbo, postdoctoral researcher in the Black Hole Initiative, a research group at Harvard University, quoted from LiveScience.
This is because black holes that are home to relativistic jets, or very large beams of matter pushed very close to the speed of light, have very hot temperatures.
Quasar 3C273 is near a supermassive black hole which is 2.4 billion light years from Earth.
According to Observatorium Greenbank in West Virginia, this region has a core temperature of about 10 trillion Celsius. However, according to Palumbo, there is still uncertainty surrounding this temperature estimate.
Supermassive black holes are very powerful and are at the centers of most galaxies. As the name suggests, supermassive black holes are huge. For example, Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy, has a mass millions of times that of the Sun.
Likewise quasar 3C273, which has such a strong gravitational pull that nothing, not even light, can escape its clutches.
The high temperatures in supermassive black holes are caused by gravity sucking in the molecules around the black hole at high speeds. The friction generated by the collisions between materials in the process can release temperatures of trillions of degrees Celsius.
For comparison, the surface temperature of the Sun is 5,500 degrees Celsius.
This temperature only increases when the black hole’s strong magnetic field pulls some nearby matter into relativistic jets that can shoot out into space for millions of light years.
