Scientists' simulation of the Supergalatic Plane show how collisions in dense star neighborhoods can smooth out swirling galaxies.

The Hubble Space Telescope captured an image of NGC 4694, a galaxy that possesses unusual properties that complicate its classification.

Neptune's elliptical, oval-shaped orbit keeps the planet an average distance from the sun of almost 2.8 billion miles (4.5 billion kilometers), or roughly 30 times as far away as Earth, making it ...

Astronomers have found one of the largest-ever black holes in giant galaxy NGC 4889, some 300 million light years away. The Hubble space telescope has captured an incredible image of elliptical ...

Black holes are just one of myriad marvels in outer space. In this feature, learn the difference between pulsars and quasars, antimatter and dark matter, brown dwarfs and white dwarfs, and many ...

Celebrate a Harvest Moon lunar eclipse and an occultation of the planet Saturn, just days before Neptune reaches opposition in the sky this week.

When NASA 's Hubble Space Telescope snapped a picture of an elliptical galaxy, it caught something else in the frame: A bright, red arc of light wrapped around it. That glowing curve isn't the ...

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.

It took just a few minutes for the telescope to image Neptune close up, and another 20 to take a wider view, revealing not just the planet but myriad galaxies behind it stretching into the cosmos ...

The majority of the thousands of galaxies we’ve discovered out in the universe fit into relatively well-defined categories: spiral galaxies like our Milky Way, elliptical galaxies which are long ...

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.
