7 stunning NASA images revealing Universe's mysteries

Usually seen in shades of gray, this composite photo of the Moon is a riot of reds, oranges, and blues. These unusual colors help scientists study what the Moon’s soil is made of.

This is a galaxy cluster with two streams of superheated gas crossing one another.⁣ This comet-like tail of hot gas trailing behind split into two streams as the galaxy hurtled through space.

The bright star taking center stage is a Wolf-Rayet star, located about 30,000 light-years away in the 'Carina' constellation. The blue bubble surrounding it is a Wolf-Rayet nebula.

Research suggests that the stars at the center of this cluster are about 200,000 years old, while those on the outskirts are about 1.5 million years of age.

45 million light-years from Earth, this galaxy has patches of glowing pink spots, signs of nebulae where new stars are being formed, tucked within its winding spiral arms.

This image of a pair of galaxies – one elliptical (left) and the other spiral (right) – reveals the supermassive black hole at the center of the large spiral galaxy. As the black hole gobbles up surrounding gas and dust, that material heats up and lets out a tremendous amount of energy, making the galaxy’s core shine brightly.

Residing 7,100 light-years from Earth, the Bubble Nebula itself is a whopping 7 light-years across. The seething star that forms this nebula is 45 times more massive than our Sun!
