In this new Hubble image two objects are clearly visible, shining brightly. When they were first discovered in 1979, they were thought to be separate objects — however, astronomers soon realized that these twins are a little too identical! They are close together, lie at the same distance from us, and have surprisingly similar properties. The reason they are so similar is not some bizarre coincidence; they are in fact the same object.
Hubble Sees an Ancient Globular Cluster This image captures the stunning NGC 6535, a globular cluster 22,000 light-years away in the constellation of Serpens (The Serpent) that measures one light-year across.
From Nasa: Located some 25 million light-years away, this new Hubble image shows spiral galaxy ESO 373-8. Together with at least seven of its galactic neighbors, this galaxy is a member of the NGC 2997 group. We see it side-on as a thin, glittering streak across the sky, with all its contents neatly aligned in the same plane.
Bursting with stars: Markarian 209, a blue compact dwarf galaxy, is captured in the middle of an intense burst of star formation, as seen in the light blue cloudy region in the top right corner. The dominant population of stars is under 3 million years old, compared with our 4.6 billion year-old sun. [Hubble/ESA]
Hubble Sees the Beautiful Side of Galaxy IC 335 as seen in front of a backdrop of distant galaxies. IC 335 is part of a galaxy group containing three other galaxies, and located in the Fornax Galaxy Cluster 60 million light-years away.
