Courtesy of Hubble:

The deepest image of the Universe ever captured.

Most patches of light in the image are galaxies, each one is home to billions of stars.

This is what happens when galaxies collide; a billion year gravitational waltz.

This supercomputer simulation includes images from Hubble of actual galactic collisions at different stages.

Beautiful image of the Lobster Nebula

[The Klein Universe @Klein_Universe]

Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars https://t.co/5mMgktiU8i
