In another of his great astronomical achievements, the hubble space telescope from NASA just detect a barred spiral galaxyas reported from the official website of the aforementioned North American space agency.
baptized UGC 678as seen in the image provided by Hubble and published by NASA, the gigantic galaxy is located approximately 260 million light years from Earth, more precisely in the pisces constellationand is practically located upside down, which, the researchers pointed out, allows its irregular spiral arms extend several meters.
“Barred spiral galaxies have a bar-shaped star structure extending from opposite sides of the galaxy’s central bulge, while bars form in spiral galaxies when the orbits of stars near the heart of the galaxy become unstable and stretched.”
“As their orbits lengthen, they create a bar. The bar grows as its gravity captures more and more nearby stars. UGC 678 bar is weak”, added the specialists.
Just like humans, stars have a normal life cyclethat is, they are born, grow and eventually grow old and die, while the end of a star’s life can be marked by truly amazing events, including giant supernova explosionsthe creation of unimaginably dense neutron stars and even the birth of black holes.
It was recently discovered that UGC 678 hosted one of these events: In 2020, a robotic telescope scanning the night sky for dangerous asteroids discovers evidence of a massive supernova explosion in the galaxy.
