If there is anything to know about black holes, it is that these space objects consume everything in their path. But there have been cases where materials are expelled, and recently, scientists were able to find a very unusual type of black hole.
Express reports that researchers discovered a black hole 250 million light years from Earth. What’s unusual about this black hole is that it emits bursts of radiation every nine hours, compared to regular black holes that emit irregularly shaped bursts of radiation. Experts were shocked and expressed that this is the first time they have witnessed a black hole that regularly emits X-rays.
Researchers at the University of Leicester analyzed the black hole in an attempt to understand the regular patterns of X-ray flashes. They discovered that regular X-ray eruptions were the result of a dead star escaping from its encounter with the black hole, and now it orbits around it. The orbit took nine hours to complete, which explains the regular patterns of X-ray flashes.
According to the university’s chief astronomer, Andrew King, “This white dwarf is locked in an elliptical orbit near the black hole, orbiting every nine hours. At its closest approximation, about 15 times the radius of the black hole’s event horizon, gas is drawn from the star in an accretion disk surrounding the black hole. This results in the black hole releasing X-ray flashes that would be detected by spacecraft. “
King revealed that this event will only be visible to current telescopes for a limited time, which is 2,000 years. “He will do his best to escape, but there is no escape. The black hole will eat it more and more slowly, but it will never stop.
Earlier, NASA and ESA’s Hubble Space Telescope discovered a multi-armed spiral galaxy 95 million light years from Earth. Formally known as NGC 2273, NASA describes the phenomena as a pinwheel galaxy with rings inside the spirals, creating a spiral within the spiral. The agency calls this a multiring structure, and this is what makes this particular galaxy unusual compared to the other galaxies that Hubble has discovered.
