![]() After some cosmic shuffling between all three black holes, one of the original binary black holes likely got slingshot out into the great empty. The introduction of a third is likely the result of galaxy mergers sometime in the distant past, van Dokkum said. Two supermassive black holes in the center of a galaxy are rare. Van Dokkum told Live Science that one explanation could be “a three-body interaction.” This is where two supermassive black holes in a tenuous balance were disturbed by a third. Cosmic shufflingīut how could such a thing happen? That’s the tricky part. “If confirmed, it would be the first time that we have clear evidence that supermassive black holes can escape from galaxies,” van Dokkum said. The best explanation is that a supermassive black hole is on a tear through the gas surrounding its former home galaxy. Notably, it didn’t fan out into space, and it got brighter farther away from its point of origin. The “thin line” the scientists observed had different characteristics than an astrophysical jet. But Dokkum and his team had a hunch that’s not what they were looking at. It’s not uncommon for supermassive black holes to launch “astrophysical jets” of material into space. Like most galaxies, it likely held a supermassive black hole at its center. The dwarf galaxy in question is 7.5 billion light years from our planet. The supermassive black hole at the center of the second galaxy disturbed the balance of the first two, ejecting one of them out into the cosmos. Two supermassive black holes existed in peace with each other until their galaxy gobbled up a second galaxy. From a detailed analysis of the feature, we inferred that we are seeing a very massive black hole that was ejected from the galaxy, leaving a trail of gas and newly formed stars in its wake.”Īn illustration of how (possibly) a supermassive black hole came to be hurtling through space. “Using the Keck telescope in Hawaii, we found that the line and the galaxy are connected. “We found a thin line in a Hubble image that is pointing to the center of a galaxy,” van Dokkum told LiveScience. And in an era where the James Webb Telescope seems to make news every few weeks, let’s raise a glass to the Hubble Telescope - the original intergalactic looking glass. It goes to show that when you are talking about space, there’s just no way to wrap your head around the distances at play. This formidable entity boasts a width equal to 60 Earth-sized planets. The gas trail is twice the length of our own galaxy. On December 2, within 24 hours, a coronal hole, or dark spot, emerged on the surface of the sun. That’s how Pieter van Dokkum, a professor of physics and astronomy at Yale University, was able to spot it, according to Live Science. In its wake, the supermassive object is trailing a long strand of star-forming gases. “Finding Planet Nine like discovering a cousin living in the shed behind your home you never knew about.An enormous black hole has left the center of its home galaxy and is hurtling through space at a rate of 5.6 million kph. “The outskirts of the Solar System is our backyard,” adds Loeb. We only know the broad region in which it may reside.” “Other telescopes are good at pointing at a known target, but we do not know exactly where to look for Planet Nine. “LSST has a wide field of view, covering the entire sky again and again, and searching for transient flares,” said study co-author Prof Avi Loeb. Researchers verify ‘extremely odd’ black hole physics.Mysterious object may be smallest black hole ever found.The LSST will use a 3.2-gigapixel camera at Chile’s Rubin Observatory to photograph the entire visible sky every few nights for 10 years. The authors propose using the upcoming Legacy Survey of Space and Time (LSST) to look for the accretion flares. Now, two astrophysicists at Harvard University, US, have suggested a way to investigate this: look for the bursts of electromagnetic radiation, or ‘accretion flares’, that would be produced as this black hole ripped apart and swallowed any nearby icy objects.

These as-yet-unseen black holes are thought to have formed a fraction of a second after the Big Bang. Last year, scientists in the UK and US suggested that Planet Nine, which is also known as Nibiru, could instead be a primordial black hole. But the existence of a ninth planet orbiting our Sun could explain certain features of the outer Solar System, such as the clustering together of icy rocks called ‘trans-Neptunian objects’ with similarly tilted orbits. Planet Nine has never been seen directly. Planet Nine could be a grapefruit-sized black hole, say astrophysicistsĪstrophysicists have suggested that the hypothetical Planet Nine could be a tiny black hole, and they’ve proposed a way to find out.
