Like two skaters grabbing hands while passing, the two galaxies NGC 5427 (lower left) and its twin NGC 5426 (upper right), are beginning a collision that could take a hundred million years to complete. Already a bridge-like feature has begun to form between the galaxies. This intergalactic bridge acts like a feeding tube, allowing the twins to share gas and dust with one other across the 60,000 light years of space separating them.
In 2004, astronomers discovered a star composed entirely of diamond, measuring 4,000 km across and 10 billion trillion trillion carats. 50 light years from Earth, the diamond star is classified as a crystallized white dwarf, the hot core that remains after a star burns out. Only recently have scientists been able to study the contents of the white dwarf, and they’ve confirmed that the crystallized carbon interior of the star is, in fact, the galaxy’s largest diamond.
This just doesn't look like a real picture. Turns out it's from the Hubble telescope.
