Yellow clouds tens of thousands of light-years up from the center of the Milky Way, and that have puzzled astrophysicists for more than 70 years, may have a final explanation.
Space experts discovered the celestial mystery hanging above our galactic house in the 1950s and named it North Polar Spur.
At first people thought it was just part of space debris in the night sky, but some astronomers have argued that it was part of an expanding shock wave.
For this to be true, another cloud could have been seen below the Milky Way galaxy but no evidence of this was discovered until 2010, a space telescope captured an extremely faint, gamma-way glow from two huge bubbles.
Yellow clouds seen rising from the center of the Milky Way have made experts scratching their heads for decades.
And now new images from the orbiting telescope known as eROSITA help make two concrete views.
Based on the energy required to make the huge mushroom cloud bubbles, experts say the first option was a wave of thousands of stars suddenly appearing and then instantly exploding.
The alternative option suggests that the supermassive black hole at the core of our galaxy may have picked up a large cloud of passing gas, eating up half of the cloud as its energy spewed above and below the Milky Way galaxy, causing bubbles.
John Kataoka, an astronomer at Waseda University in Japan, said of the first idea: “ The abundance of the mineral is very small.
The new images from the orbiting telescope helped astronomers come up with two ideas of what yellow clouds are
“So I don’t think the starburst activity happened.”
Peter Bredahl, an astrophysicist at the Max Planck Institute for Extraterrestrial Physics in Germany, added that he agreed that the second idea is the most likely:
He said: We did some analysis.
‘I think now [the debate] Done more or less.
The two teams agree with that, there was a massive explosion at the center of the galaxy about 15 to 20 million years ago that we can still see today.
Researchers at NASA’s Jet Propulsion Laboratory, California Institute of Technology and Santiago High School suggested last year that the Milky Way might be home to alien civilizations, but there is a strong possibility that most of them are dead.
The statement comes from those who used an updated version of the equation to calculate the potential existence of intelligent life, and designed aliens may have appeared about eight billion years after the formation of our galaxy.
With these results, the team included the idea that the advancement of science and technology inevitably leads to the destruction of civilizations and because humans have not yet communicated outside our planet, scientists now believe they know why.
