Black holes are among the most elusive of space entities as these can also be quite hard to spot. NASA has recently reexamined an image of a distant galaxy taken by the Hubble and discovered a massive black hole in the center.
The Hubble Space Telescope snapped a photo of the distant galaxy Circinus 20 years ago. The Circinus galaxy is found 13 million light-years away from Earth, the image of which has recently been revisited by NASA. The scientists found that at the heart of this distant galaxy lies a massive black hole. The environment in which this black hole is situated as the scientists have seen is also bright enough to be picked up by telescopes here on Earth.
“The black hole is pumping hot gas out of the galaxy’s core, forming the purple-colored streamers near the top of the image,” said NASA about the discovery. “Hot pink-colored gas is being ejected out of the Circinus Galaxy’s central region by the massive black hole suspected to be lurking inside. Much of the galaxy’s gas, however, is concentrated in two rings.”
The Circinus galaxy, also known as ESO 97-G13, had long been existing but it was only during the 1970s that astronomers finally noticed. This is due to its location, as the Circinus galaxy is close to the plane of our own Milky Way galaxy, so it ends up being hidden under the cosmic clouds and gas that is present.
The Hubble Space Telescope is already on its last run before it is to be retired by the agency in 2021.
Onto other discoveries, NASA has also released an image of Earth that had what is believed to be dark matter sprouting out like hairs. Dark matter is believed to be an invisible force that is responsible for holding galaxies and clusters together, making it an important entity in space. However, it also happens to be impossible to spot with the use of the scientific instruments that astronomers make use of today. Scientists have yet to figure out what exactly makes up dark matter despite the universe being 27 percent dark matter.
