What happens when galaxies collide: Hubble showcases six mergers

To celebrate a new year, the NASA/ESA Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.

It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions. The Milky Way typically forms star clusters with masses that are 10 thousand times the mass of our Sun. This doesn’t compare to the masses ...

Hubble Locates a New Gem in Space

The Hubble Space Telescope (HST), which is running its 25th year in the space currently, spotted a little gem – a planetary nebula, there. The planetary nebula known as “NGC 6818” or “Little Gem Nebula” is an intergalactic cloud of dust, helium, hydrogen and many other ionized gases. It is situated in the constellation of Sagittarius also called “The Archer”, ...
