Mystery Objects Detected Near Milky Way’s Supermassive Black Hole

 

Black-Hole-Near-Center-of-the-Milky-Way

 

 

In 2018, astronomers discovered several bizarre objects at the Galactic Center using 12 years of data taken from W. M. Keck Observatory on Mauna Kea, Hawaii. The objects are concealing their true identity behind an opaque screen of dust; they look like gas clouds, but behave like stars. “These compact dusty stellar objects move extremely fast and close to our Galaxy’s supermassive black hole. It is fascinating to watch them move from year to year,” said astronomer Anna Ciurlo at UCLA. “How did they get there? And what will they become? They must have an interesting story to tell.”  (more…)

Mysteries of The Oort Cloud

Oort Cloud

 

The coldest, darkest reaches of our Solar System – a region still to be visited by human spacecraft – is a strange, frigid cloud that contains material from other stars and an unconfirmed object known as Planet Nine that may actually be a planet-mass black hole. This forbidding uncharted region, an enormous bubble of material encasing the planets and our Sun, is known as the Oort Cloud. This far-away shell surrounding our Solar System underscores Edwin Hubble’s observation in 1936 that “with increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows.”

Primordial Black Holes — “Does a Relic of the Big Bang Exist in Our Solar System?” 

 

Primordial Black Hole

 

Astronomers may soon be able to confirm the existence of a primordial black hole –gravity wells formed just moments after the Big Bang–in our Solar System with gravitational-wave experiments that will look back to a time before the formation of the first stars. “Ancient black holes would give us access to physics we would never otherwise be able to do,” wrote Dan Hooper, head of the theoretical astrophysics group at FermiLab, in an email to The Daily Galaxy. “If primordial black holes are real,’ he wrote, “they’d have potential to solve a whole host of the biggest problems in cosmology, not the least being the mystery of dark matter, considered to be the backbone to the structure of the universe.”

“Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution,” said Liu Jifeng, astronomer at the National Astronomical Observatory of China and first author of a 2019 study of  a black hole known as LB-1,  discovered lurking at the far side of the Milky Way with a mass that is around 70 times larger than our sun with an orbiting blue monster, a star eight times the size of the sun.. “LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation.”

LIGO Black Holes

 

Astrophysicists have discovered a dozen black holes —“invisible one-way doors out of our universe” —gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way Galaxy, which in May, 2019 suddenly brightened, appearing like a massive, dormant volcano.

Black Hole

 

“If this monster was at the center of the Milky Way it would likely make life on Earth impossible with the huge amounts of x-rays emanating from it,” said Christian Wolf, with the Australian National University (ANU) Research School of Astronomy and Astrophysics who made the momentous detection in 2018. “It would appear 10 times brighter than a full moon, an incredibly bright pin-point star that would almost wash out all of the stars in the sky. It’s probably 10,000 times brighter than the galaxy it lives in.” So bright, that it if we were approaching the galaxy in a starship, the object would so blind our view that  we could not see the galaxy itself.
