Three different exiled stars, hundreds of light years away from their nearest neighbors have all recently died in our indifferent and uncaring universe.
The Hubble Space Telescope (HST) has recently gathered new data that shows three (3) massive starts discovered between the years of 2008 and 2010 went supernova in the lonely, cold, dark spaces space between galaxies. What makes these expositions remarkable is that dying stars typically go supernova inside galaxies populated by billions of other stars.
Due to the “light show” that the stars provided scientists with, the experts might finally be able to start answering some of the questions referring to those dark, empty spaces between galaxies, since currently they vertically know nothing about them. They are some of the hardest places in the universe to research.
When the three (3) stars were first discovered, between 2008 and 2010, the researchers questioned whether or not they could be embedded in faint galaxies due to the rarity of an exile, as well as the low image quality provided by the telescope on Mauna Kea (Hawaii). However, the recent Hubble images did provide experts with proof that the supernovas are in fact exiled.
The researchers said that the supernovae were type Ia, a kind of stellar explosion that occurs when a smaller star is being absorbed by a larger star, with Melissa Graham, lead researcher and professor at the University of California, Berkeley, giving a statement explaining that:
“The companion was either a lower-mass white dwarf that eventually got too close and was tragically fragmented into a ring that was cannibalized by the primary star, or a regular star from which the primary white dwarf star stole sips of gas from its outer layers. Either way, this transfer of material caused the primary to become unstably massive and explode as a Type Ia supernova”.
She goes on to add that her and her team have brought forward the best evidence so far that intracluster stars really do explode as Type Ia supernovae, but that they also confirmed previous research claiming that hostless supernovae can be used in tracing the population of intracluster stars. This in turn helps extent the technique to other clusters sitting at greater distances.
The study, published earlier this week in the Astrophysical Journal, informed that the supernovas were all 300 light years away from their nearest neighbors. To put things in perspective, that distance is 100 times bigger than the one our sun has to its closest stellar neighbor, Proxima Centauri.
