Hubble Telescope finds 6 DEAD galaxies! Killed by Fast and Furious lifestyle
In yet another miracle made possible by the Hubble Telescope, 6 mysterious galaxies have been found. However, they are very much dead.
What should have been the cradle of stars was found to be dead. The Hubble Telescope just found something that is mysterious, odd, and perhaps even disturbing. The Hubble Space Telescope has found not one or two, but as many as 6 galaxies that are dead, as far as their role of birthing stars is concerned. The Hubble Telescope was looking back in time to a period when the universe was some 3 billion years old. In this period, the Universe went through the most intense period of star birth in its history.
What the astronomers behind the Hubble Telescope were expecting was a lively region, instead they encountered dead galaxies. Both NASA's Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) were looking at objects in that period and time and came across six early, massive galaxies, but they were all "dead". According to NASA, "At this point in our universe, all galaxies should be forming lots of stars." They should not have been dead.
What caused these galaxies to die? They exhausted all the fuel that was there. And after exhausting the fuel for star formation, these galaxies were literally running on empty, NASA said. The agency also revealed that these galaxies had run out of the cold hydrogen gas needed to make stars and that was the end for them. The study was published in the journal Nature.
A Fast and Furious Lifestyle Done It? So, what led to the disappearance of the cold hydrogen in the first place? Some of the explanations include the hypothesis that the six galaxies lived a fast and furious existence, creating stars in a remarkably short time and then died quickly. "Why they shut down star formation so early is still a puzzle," NASA revealed.
Or is a black hole the killer? Lead author Kate Whitaker, assistant professor of astronomy at the University of Massachusetts, Amherst said, "Did a supermassive black hole in the galaxy's center turn on and heat up all the gas? If so, the gas could still be there, but now it's hot. Or it could have been expelled and now it's being prevented from accreting back onto the galaxy. Or did the galaxy just use it all up, and the supply is cut off?"
Hubble Telescope: While answers are proving elusive, it does add mystery to the case. Also, we have got to know so much about galaxies. And as we too live in a galaxy - the Milky Way Galaxy - it will go a long way in increasing our understanding of it, including whether it is dying or still young. And all of this amazing information has been collected by the Hubble Telescope.
And what is the Hubble Space Telescope? The Hubble Space Telescope is a large telescope in space. It is a project of international cooperation between NASA and ESA (European Space Agency). It was launched into orbit by space shuttle Discovery on April 24, 1990. Hubble orbits about 547 kilometers (340 miles) above Earth. It is the length of a large school bus and weighs as much as two adult elephants. Hubble travels about 5 miles per second. Hubble is solar-powered.
What does Hubble Telescope do? Hubble takes sharp pictures of objects in the sky such as planets, stars and galaxies. Hubble has made more than one million observations. These include detailed pictures of the birth and death of stars, galaxies billions of light years away.
