Is this galaxy shaped like a spiral, or is it more of an elliptical? Astronomers have long debated the answer to this question, because it seems to have properties of both. Known as Centaurus A, or NGC 5128, this strange galaxy is located in the southern constellation of Centaurus, and it lies somewhere between 10 and 16 million light-years away from Earth; its exact distance is another question that is still up for debate. Astrophotographer Ron Brecher created this glittering view of the galaxy using data acquired from an observatory in New South Wales, Australia. (Image credit: Ron Brecher)

A lunar "halo" lights up the night sky above the 3.6-meter telescope at the La Silla Observatory in Chile. This phenomenon happens when the moon is at an altitude of about 22 degrees above the horizon, where light refracts through icy cirrus clouds. "Light rays that do this tend to 'bunch up' at the angle that represents the least amount of deviation from their original path. For the particular shape of ice crystal lurking within the cirrus clouds, this minimum deviation angle happens to be around 22 degrees," ESO officials said in a description. (Image credit: B.

The interstellar comet Borisov appears to come face-to-face with a distant spiral galaxy in this image from the Hubble Space Telescope. Hubble captured this image on Dec. 12, as the interstellar comet was racing through the inner solar system. At the time, the object was about 260 million miles (420 million kilometers) from Earth, while the unnamed background galaxy (officially designated 2MASX J10500165-0152029), is nearly half a billion light-years away. The galaxy appears smudged because Hubble was tracking the motion of the comet, which was zooming through space at a speed of about 109,000 mph (175,000 km/h). (Image credit: NASA/ESA/Hubble/D.

This Hubble Space Telescope image reveals the gradual self-destruction of the asteroid (6478) Gault, whose ejected dusty material has formed two long, thin, comet-like tails. The longer tail stretches more than 500,000 miles (800,000 kilometers) and is roughly 3,000 miles (4,800 km) wide. The shorter tail is about a quarter as long. The streamers will eventually disperse into space. Full Story: Rare Disintegrating Asteroid Spied by Hubble Telescope(Image credit: NASA, ESA, K. Meech and J. Kleyna (University of Hawaii), and O.

When the Hubble Space Telescope turned its gaze toward the remote galaxy known as the "Sunburst Arc," it saw not one but 12 separate images of the lone cosmic object. That's because there's a massive galaxy cluster in the foreground warping the light with its intense gravitational pull. This illusion is known as gravitational lensing, a phenomenon that Albert Einstein first described in his theory of general relativity. "This 'funhouse mirror' effect not only stretches the background galaxy image, but also creates multiple images of the same galaxy," NASA officials said in a statement. (Image credit: NASA/ESA/E. Rivera-Thorsen )
The spiral galaxy NGC 1706 may look a bit isolated drifting through the cosmos in this Hubble Space Telescope image, but this lonely galaxy has no shortage of neighbors.

In this peculiar-looking panoramic shot of the Paranal Observatory in Chile, the Milky Way appears to form two tornado-shaped columns of starlight that extend down from the heavens to Earth's surface. This illusion is the result of the photographer, the European Southern Observatory's Petr Horálek, projecting an entire 360-degree panorama onto a flat, rectangular image. In reality, the Milky Way arcs across the sky from one horizon to the other; the fact that it appears to spread out across the top of this image is merely a product of the illusions. Also visible here are the Magellanic Clouds, the Pleiades star cluster, the bright planet Jupiter and several nebulas. (Image credit: P. Horálek/ESO)

Centaurus A, also known as NGC 5128, is one of the brightest objects in the night sky of the Southern Hemisphere. It's located 11 million light-years from Earth in the constellation of Centaurus.

Swimming through a group of galaxies more than 200 million light-years away from Earth is the so-called "jellyfish" galaxy named ESO 137-001. This celestial jellyfish is a spiral galaxy much like the Milky Way, but it has long "tentacles" of hot gas streaming away from the galactic disk. Scientists aren't sure how the gas is being stripped away, but NASA's James Webb Space Telescope may be able to shed some light on the origin of those tentacles by studying them in unprecedented detail after its planned launch in 2021.

The venerable observatory turned its attention to NGC 3169, a spiral galaxy about 70 million light-years away in the constellation of Sextans, the Sextant. The "sharply angled perspective" that the space telescope imaged shows a sort of cosmic barrier that makes the viewer feel as though they're peering over the edge to see the galaxy's center, Hubble scientists said in a description of the image.
