Hubble Finds Galaxy’s Stars Scattered Far from Home

This hypnotizing regard by a Hubble Space Telescope shows universe NGC 7714 in a state of turmoil.

Between 100-200 million years ago, when dinosaurs roamed Earth, NGC 7714 got too tighten to another universe (NGC 7715, out of frame, right) and a impassioned tidal army dragged one of a once-elegant turn arms low into intergalactic space. The sparse stars now form a stellar overpass to a second galaxy, exchanging star-forming material.

Both galaxies are approximately 100 million light-years from Earth.

This aroused galactic collision wasn’t all bad news for NGC 7714, however. The confront caused intrusion in a interstellar gasses it contains, triggering a call of new star arrangement via a galactic spirals. The call of star birth has been prisoner as splendid blue by Hubble’s optics.

Due to a demoniac birth of new stars, astronomers impute to NGC 7714 as a Wolf-Rayet starburst galaxy. Many of a young, large stars are famous as Wolf-Rayets, that as really massive, hot, scattered stars that live quick and die young, shedding outrageous quantities of superheated gases before they raze as supernovae.

So what started as a aroused galactic collision, finished adult as a frenzy of star birth that, eventually, will see a Wolf-Rayets explode, seeding NGC 7714 with heavier elements that will go on to form other stars and, ultimately, star systems.
