NASA’s dazzling photo hides a secret

A star invisible to the eye is a powerful force at the center of Metropolis.

The brilliant star cluster Messier 4, the closest cluster to Earth at about 6,000 light-years away, contains hundreds of thousands of stars. it’s worth seeing. Now, NASA employed its legendary Hubble Space Telescope to reveal what’s likely black holeabout 800 times the mass of Sundayin the center of the star cluster.

“You can’t do this kind of science without Hubble,” said Eduardo Vitral of the Space Telescope Science Institute. statement,

This black hole is rare: it is not a small black hole, it is a type of the rogue object that spins our galaxy (Scientists estimate that there are many more hundred million Of these only in our Milky Way galaxy). And this is not one of the monstrous “supermassive” black holes that lie at the center of galaxies – such as Sagittarius A* – which weigh millions of times more than the Sun (astronomers rare photo taken of this massive Milky Way object). Rather, the new observation is a curious “intermediate mass” black hole, an oddity scientists have many questions about — like why can they be so rare?

Black holes have unimaginable mass, with gravity so strong that even light cannot escape. How, then, do researchers uncover evidence of an invisible object? They looked at Hubble’s observations of Messier 4 from a 12-year period, noting how stars moved near the cluster’s core, “like bees moving around a hive,” NASA explained.

Research, recently published in Monthly Notices of the Royal Astronomical Society, determined that the motion of stars was influenced by a powerful center of gravity. They could not realistically explain the behavior of stars from other forces, such as dense stars near the core. The evidence points to a singular black hole, relatively small among the grander Messier 4s.

“It’s too small for us to be able to interpret other than it being a single black hole,” Vitral said.

However, the matter of the curious force at the center of Messier 4 is still ongoing. Although the evidence for a black hole is compelling, there is a chance that other forces may be at play, such as previously unknown star activity and physics.

Hubble must be watching.
