A team of astrophysicist say quasars , some of the most brilliant phenomena in the universe , are likely because of collisions between galaxies .
Quasars are a type of active astronomical cell nucleus ; they lie in wait at the centers of galax and are very lustrous , often launching material outward in superheated special K of textile . But for decades , astrophysicists have not know what chip in rise to quasars .
Now , a group of scientists purport that quasars emerge from the gravitative forces at play when galaxies clash . Theirresearchis published in the Monthly Notices of the Royal Astronomical Society .

“ quasar are one of the most extreme phenomenon in the universe , ” say study co - generator Clive Tadhunter , a physicist at the University of Sheffield , in a universityrelease . “ What we see is potential to represent the future of our own whitish path galaxy when it collides with the Andromeda Galax urceolata in about five billion years . ”
Quasars werediscovered in the fifties ; since then , scientists have found that they are among the most gumptious objects in the universe . quasar often outshine the stars in their galaxy ; their brightness is infer from the pitch-dark hole at their core accreting and eat up nearby stuff , releasing energy .
As the researchers find , the same process seems to be what make quasars in the first place . They compared data from 48 galaxies with quasars at their core to over 100 galaxies without quasars . The observations came from the Isaac Newton Telescope in La Palma , one of the Canary Islands .
Quasars are also take note by theEvent Horizon Telescopeand the Webb Space Telescope ; a recentWebb trope revealed an ancient quasarthat was encircled by at least three other galaxy in a “ galactic nautical mile . ” In other quarrel , it appears that the quasar ’s Galax urceolata had sucked several others toward it .
That line up with the recent team ’s work , which found that around 65 % of the observed quasar - host wandflower showed signs of Galax urceolata mergers or clash in the yesteryear . Only around 22 % of observed galax miss quasars showed signs of similar interactions .
Gravity causes monolithic structure to interact with each other , even in the immensity of space . Whether the collision between the Milky Way and Andromeda will yield a quasar , no human can say for certain . But further observations of these luminous objects could bring a hand to computer models examination galaxy phylogenesis and fundamental interaction , so we might learn more about where the cosmos ’ most spectacular object came from .
