‘Exiled’ tri-stars died a lonely death in the void of universe but without first giving off a massive show of intergalactic fireworks

Last week, it was revealed that a trio of explosion from stars hundreds of light years away from anything nearby.

Stars usually go out in giant explosions that mark their deaths for a very long time. These events are called supernova. However, these three stars mentioned above—according to the Hubble Space Telescope—exploded away from anything else, in the void of space.

Scientists hope that the se shining beacons give them an idea of what’s in the void of space, the in-between of galaxies.

These supernova aren’t new, scientist knew of them since 2008 and 2010 thanks to a telescope in Mauna Kea, Hawaii. However, Hubble’s clearer and sharper images give scientists much more information.

Earlier pictures couldn’t tell whether these supernova were really alone or were just in faint galaxies. Hubble’s clearer images erased any trace of a doubt: they are exiles.

To put things into perspective: these supernova were around 300 light-years away from their galactic neighbors. According to Robert Sanders of the University of California “nearly 100 times farther than our sun’s nearest stellar neighbor, Proxima Centauri, 4.24 light years distant.” However, this doesn’t mean that there wasn’t anything near them like asteroids or planets, it just means there wasn’t anything that could significantly hamper the debris from their explosions.
