We have a vast collection of colliding galaxies cataloged, but this example — designated with the name NGC 6745 — is surely one of the most unusual-looking ones. Within this frame, we see the main galaxy and what’s left of its former counterpart, which can be found in the lower right, almost out of frame. The larger of the two exhibits characteristics of a spiral galaxy, but after its encounter, it took the shape of a peculiar galaxy.

This picture, taken by the NASA/ESA Hubble Space Telescope’s Wide Field Planetary Camera 2 (WFPC2), shows a galaxy known as NGC 6872 in the constellation of Pavo (The Peacock). Its unusual shape is caused by its interactions with the smaller galaxy that can be seen just above NGC 6872, called IC 4970. They both lie roughly 300 million light-years away from Earth.

Space Photos - Satellite Images - Image of the Day --- A coronal mass ejection associated with an M-class flare on the sun hurled a long stream of plasma into space on Aug. 24, 2014. Image captured by the STEREO (Behind) spacecraft. A view of the sun in extreme UV light combines here with a broader visible light view of the sun's corona. Much of the plasma lacked sufficient kinetic energy to break free from the sun's gravity, and fell back into the sun.

This stunning image of two nebulas in the constellation Sagittarius was taken in one night by stargazer Terry Hancock. Hancock took the image of M8 and M20, the Lagoon and Trifid Nebulas, on July 6 from Fremont, Michigan. He was able to capture the image just in time.

Astronomers have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's center than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored.

From ground-based telescopes, the so-called "ant nebula" (Menzel 3, or Mz 3) resembles the head and thorax of a garden-variety ant. This dra...

NASA has released an image taken by the Hubble space telescope of a cluster of stars in a neighboring galaxy. Its name -- NGC 121 -- This so-called globular cluster is in a galaxy known as the Small Magellanic Cloud, which, at a distance of about 200,000 light-years, is one of the Milky Way's closest neighbors

Hubble-X is a glowing gas cloud, one of the most active star-forming regions within galaxy NGC 6822. The name Hubble-X does not refer to the shape of the gas cloud, but rather is derived from a catalog of objects in this particular galaxy.

Combining almost opposite ends of the electromagnetic spectrum, this composite of the Herschel in far-infrared and XMM-Newton's X-ray images shows how the hot young stars detected by the X-ray observations are sculpting and interacting with the surrounding ultra-cool gas and dust, which, at only a few degrees above absolute zero, is the critical material for star formation itself. Both wavelengths would be blocked by Earth's atmosphere, so are critical to our understanding of the lifecycle ...

Peering through Titan's hazy atmosphere, a high-resolution camera aboard NASA's Cassini spacecraft revealed Saturn moon's largest seas, the largest of which is Kraken Mare, and hydrocarbon lakes. Titan stands out as the only place in the solar system, besides Earth, to support stable liquids on its surface; its lakes are made of liquid ethane and methane. The image, taken on Oct. 7, 2013, was snapped at a distance of about 809,000 miles (1.303 million kilometers) from Titan.

WIRED Space Photo of the Day | June 23, 2014: Strange Supernova | This bright spiral galaxy is known as NGC 2441, located in the northern constellation of Camelopardalis (The Giraffe). However, NGC 2441 is not the only subject of this new Hubble image; the galaxy contains an intriguing supernova named SN1995E, visible as a small dot at the approximate centre of this image. Supernova SN1995E, discovered in 1995 as its name suggests is a ...
