The Small Magellanic Cloud, a dwarf galaxy about 200,000 light-years from the solar system, can be seen with the naked eye ...

Fluffy strands of cosmic gas and dust illuminated by bright young stars form a beautiful cloudscape in a neighboring nebula.

N ASA's Hubble Space Telescope has captured a cosmic bullseye. The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an "arrow"—a far smaller blue dwarf galaxy—shot ...

The Hubble Space Telescope image offers an up-close view of one section of the nebula, which is largely shaped by a young central star cluster called Dolidze 25, located outside of the image frame.

This proved that the "nebula" were actually separate systems outside and independent of our galaxy. It was the first evidence of galaxies outside our own, and Hubble soon went on to discover about ...

Hubble observed NGC 5042 in six wavelength bands from the ultraviolet to infrared to create this multicolored portrait. The galaxy's cream-colored center is packed with ancient stars, and the ...

In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. ESA/Hubble & NASA, R.

Hubble and Keck also confirmed which galaxy dove through the Bullseye, creating these rings: the blue dwarf galaxy that sits to its immediate center-left.

Hubble had already used this knowledge in his 1924 discovery that the Andromeda nebula, containing a variable star, was more than 900,000 light years from Earth -- way beyond our own galaxy -- a ...
