According to Australian scientists, the object, codenamed J0529-4351, may be 300 to 500 trillion times brighter than the Sun and consume a star the size of ours every day.

Australian National University scientists have discovered the brightest object in the known universe. Quasar J0529-4351 Nature astronomy He presented it in his columns.

A well-known feature of black holes is their strong gravity, which not even light can escape. This makes them invisible, but their accretion disc shows where they are. In this region, matter travels at the speed of light, which heats up so much that the disk becomes visible.

The accreting disks of supermassive black holes at the center of galaxies make quasars the brightest objects in the universe.

The only reason they don't light up the sky all the time is because there isn't anything near us.

Of course, after the discovery of J0529-4351, it's necessary to think on a new scale about what it looks like when something is bright. The apparent brightness of this object is similar to that of two other powerful quasars, J0100+2802 and J2157-3602, and is located at a similar distance, about 12 billion light-years. However, there is a significant difference between the latter two and the present discovery.

The brightness of J0100+2802 and J2157-3602 is also amplified by gravitational lensing. Although these objects are undoubtedly bright, when gravitational lensing is taken out of the equation, their brightness is less than that of J0529-4351.

However, no gravitational lens played a role in detecting the latter, so – if we accept that there is no object that plays this role, but it has not escaped the attention of scientists until now – it can be said that this is the brightest object ever discovered.

According to Christian Wolff, head of the research, it is estimated that the quasar in question is 300-500 trillion times brighter than the Sun.

Experts believe that J0529-4351 consumes a star roughly the size of the Sun every day. Its mass is currently estimated at 17 billion times the mass of the Sun.
