NASA scientists found evidence of darkness on the 'leading side' of Uranus' moons, which they expected to be bright.

Scientists find surprising evidence that space dust is shaping the surfaces of Uranus' largest moons.

Scientists using NASA's Hubble Space Telescope went looking for evidence of one phenomenon and found quite another.

Astronomers used the Hubble Space Telescope to image "peculiar" galaxy Arp 184 (NGC 1961) about 190 million light-years away. Remarkably, the spiral galaxy has only one visible arm.

Galaxies come in many different variations, but astronomers classify them into four main types: spiral, elliptical, irregular and peculiar.

However, not all spiral galaxies are created equal, as two recent images from the Hubble Space Telescope show. The image above shows galaxy NGC 3596, a neat and orderly spiral galaxy.

Enjoy dark skies for evening observing, then catch a meteor shower and a planetary conjunction in the morning sky this week.

Hubble space telescope discovers Uranus' day is 28 seconds longer than previously estimated. New findings improve tracking of Uranus' magnetic poles.

The formation of elliptical galaxies has long been difficult to explain with cosmological models describing the evolution of the universe from the Big Bang to now.
