Nightmare black hole is the brightest object in the universe

By Georgina Torbet February 21, 2024

A recently discovered monster black hole feasts on so much nearby material that it’s the fastest-growing of its kind on record. The beefy black hole is devouring the equivalent mass of our sun every single day, making it a record-breaker in more ways than one.

“The incredible rate of growth also means a huge release of light and heat,” said lead researcher Christian Wolf of The Australian National University in a statement. “So, this is also the most luminous known object in the universe. It’s 500 trillion times brighter than our sun.”

Known as J059-4351, it is a type of object called a quasar, where the supermassive black hole at the heart of a galaxy is so massive and active that the galactic core around it glows brightly. The black hole at the center has a mass of around 17 billion times that of the sun, making it much more massive than the relatively diminutive black hole at the center of our galaxy (Sagittarius A*, with a mass 4.3 billion times that of the sun) or even the famous, first-photographed black hole in Messier 87, which is 6.5 billion times the mass of the sun.

The discovery was first made using a telescope in Australia, then confirmed with the European Southern Observatory’s Very Large Telescope. The researchers saw the very active, hot, and fast-moving region around the black hole and were able to calculate information about its feeding pattern based on that. The material swirls around the black hole and is gradually consumed by the black hole as it falls past the event horizon.

“It looks like a gigantic and magnetic storm cell with temperatures of 10,000 degrees Celsius, lightning everywhere, and winds blowing so fast they would go around Earth in a second,” Wolf said. “This storm cell is seven light-years across, which is 50 percent more than the distance from our solar system to the next star in the Galaxy, Alpha Centauri.”

One reason that this particular black hole is so enormous is that it is very distant, so looking at it is like looking back in time to an earlier period when the universe was different from how it is today.

“The light from this black hole has traveled over 12 billion years to reach us,” co-author Rachel Webster from the University of Melbourne explained. “In the adolescent universe, matter was moving chaotically and feeding hungry black holes. Today, stars are moving orderly at safe distances and only rarely plunge into black holes.”

The research is published in the journal Nature Astronomy.

Biggest stellar black hole to date discovered in our galaxy

Astronomers have found the most massive stellar black hole in our galaxy, thanks to the wobbling motion it induces on a companion star. This artist’s impression shows the orbits of both the star and the black hole, dubbed Gaia BH3, around their common centre of mass. This wobbling was measured over several years with the European Space Agency’s Gaia mission. Additional data from other telescopes, including ESO’s Very Large Telescope in Chile, confirmed that the mass of this black hole is 33 times that of our Sun. The chemical composition of the companion star suggests that the black hole was formed after the collapse of a massive star with very few heavy elements, or metals, as predicted by theory.

Black holes generally come in two sizes: big and really big. As they are so dense, they are measured in terms of mass rather than size, and astronomers call these two groups of stellar mass black holes (as in, equivalent to the mass of the sun) and supermassive black holes. Why there are hardly any intermediate-mass black holes is an ongoing question in astronomy research, and the most massive stellar mass black holes known in our galaxy tend to be up to 20 times the mass of the sun. Recently, though, astronomers have discovered a much larger stellar mass black hole that weighs 33 times the mass of the sun.

Not only is this new discovery the most massive stellar black hole discovered in our galaxy to date but it is also surprisingly close to us. Located just 2,000 light-years away, it is one of the closest known black holes to Earth.

Stunning image shows the magnetic fields of our galaxy’s supermassive black hole

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the center of our Galaxy: how it looks in polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of Sagittarius A*. This image shows the polarized view of the Milky Way black hole. The lines mark the orientation of polarization, which is related to the magnetic field around the shadow of the black hole.

The Event Horizon Telescope collaboration, the group that took the historic first-ever image of a black hole, is back with a new stunning black hole image. This one shows the magnetic fields twirling around the supermassive black hole at the heart of our galaxy, Sagittarius A*.

Black holes are hard to image because they swallow anything that comes close to them, even light, due to their immensely powerful gravity. However, that doesn't mean they are invisible. The black hole itself can't be seen, but the swirling matter around the event horizon's edges glows brightly enough to be imaged. This new image takes advantage of a feature of light called polarization, revealing the powerful magnetic fields that twirl around the enormous black hole.

The expansion rate of the universe still has scientists baffled

This image of NGC 5468, a galaxy located about 130 million light-years from Earth, combines data from the Hubble and James Webb space telescopes. This is the most distant galaxy in which Hubble has identified Cepheid variable stars. These are important milepost markers for measuring the expansion rate of the Universe. The distance calculated from Cepheids has been cross-correlated with a Type Ia supernova in the galaxy. Type Ia supernovae are so bright they are used to measure cosmic distances far beyond the range of the Cepheids, extending measurements of the Universe’s expansion rate deeper into space.

The question of how fast the universe is expanding continues to confound scientists. Although it might seem like a fairly straightforward issue, the reality is that it has been perplexing the best minds in physics and astronomy for decades -- and new research using the James Webb Space Telescope and the Hubble Space Telescope doesn't make the answer any clearer.

Scientists know that the universe is expanding over time, but what they can't agree on is the rate at which this is happening -- called the Hubble constant. There are two main methods used to estimate this constant: one that looks at how fast distant galaxies are moving away from us, and one that looks at leftover energy from the Big Bang called the cosmic microwave background. The trouble is, these two methods give different results.
