A study of 544 star-forming galaxies observed by the Keck and Hubble telescopes shows that disk galaxies like our …
Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind’s deepest-ever view of the universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The … Read the rest of this article
Two very different galaxies drift through space together in this image taken by NASA’s Hubble Space Telescope.
The peculiar galaxy pair is called Arp 116. Arp 116 is composed of a giant elliptical galaxy known as Messier 60 (or M60) and a much smaller spiral galaxy, NGC 4647. M60 is the third brightest galaxy in the Virgo cluster of galaxies, … Read the rest of this article

The European Space Agency (ESA) has announced the winners of an international public contest called Hubble’s Hidden Treasures.
Budding amateur astronomers were invited to create beautiful color astronomical pictures from over 700,000 available images of stars, nebulae, and galaxies in the Hubble Space Telescope data archive. The vast amount of data available from Hubble means that there are at … Read the rest of this article
Astronomers using data from NASA’s Hubble Space Telescope have caught two clusters full of massive stars that may be in the early stages of merging. The clusters are 170,000 light-years away in the Large Magellanic Cloud, a small satellite galaxy to our Milky Way.

Messier 68 is located about 33 000 light-years from Earth in the constellation Hydra (The Female Water Snake). French astronomer Charles Messier notched the object as the 68th entry in his famous …
A team of astronomers using NASA’s Hubble Space Telescope has discovered another moon orbiting the dwarf planet Pluto.
They say the new moon, Pluto’s 5th, is likely irregular in shape and 6 to 15 miles across. Provisionally designated S/2012 (134340) 1, it was detected in nine separate sets of images taken by Hubble’s Wide Field Camera 3 on June 26, … Read the rest of this article
