Hubble

This stunning shot of the giant star cluster Westerlund 2 was chosen as the official 25th ...

On this day 25 years ago, the Hubble Space Telescope launched aboard the Space Shuttle Discovery in what marked the beginning of an incredible journey, and the start of a new golden age in the exploration of our Universe. In celebration of this auspicious occasion, NASA has released the official image for Hubble's 25th anniversary in low-Earth orbit. The focus of the image is the Westerlund 2 cluster, which contains roughly 3,000 stars in the scope of its glittering expanse.  Read More

The Hubble Space Telescope, imaged in orbit by the crew of the Space Shuttle Atlantis in 2...

April 24 will mark a significant milestone in the life of one of mankind's greatest scientific instruments – the 25-year anniversary of the launch of the Hubble Space Telescope. This bus-sized piece of scientific equipment has become a household name, thanks to the incredible scientific insights and iconic images it has returned over the course of a quarter-century in low-Earth orbit. Join us as we celebrate the history and achievements of NASA's flagship space telescope.  Read More

Observations from the VLT and Hubble telescopes have revealed that star formation in spher...

Astronomers have used the ESO's Very Large Telescope (VLT) in conjunction with the NASA/ESA Hubble Space Telescope to reveal the secrets of how star formation shuts down in distant galaxies, just three billion years after the Big Bang. Focusing on huge, quiescent elliptical galaxies known as spheroids, the findings are expected to improve our understanding of the evolution of the Universe.  Read More

The majority of the universe is made up of mysterious, practically invisible dark matter. But new research is beginning to help us understand it, and seems to indicate that it could be even "darker" than previously thought.  Read More

Artist's concept of aurorae and Ganymede (Image: NASA, ESA, and G. Bacon (STScI))

An ultraviolet light show has provided space scientists with the best evidence yet that the Jovian moon Ganymede has a gigantic ocean beneath its icy surface. Images captured by the Hubble Space Telescope of the aurorae in the moon's tenuous atmosphere provide what NASA calls the best evidence yet for a wet Ganymede where life could exist.  Read More

MACS J1149.6+2223 and the images of the supernova

A team of astronomers led by the Australian National University (ANU) has discovered a lens of galactic proportions. Using the Hubble Space Telescope and the Keck Observatory in Hawaii, the scientists saw a supernova not once, but four times by using the gravity of a distant cluster of galaxies to act as a natural lens that magnified and quadrupled the image of the exploding star.  Read More

Ceres from 25,000 mi (40,000 km) away (Image: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

As NASA’s Dawn spacecraft makes its final approach to Ceres, the ion-propelled spacecraft is sending the best images yet with more details about the surface of the dwarf planet. The images from Dawn have shown the presence of numerous craters and unusual bright spots that scientist hope will provide clues as to not only how Ceres formed and if it is still active, but the early history of the Solar System as well.  Read More

MUSE documented over 20 celestial objects missed by Hubble's Deep Field South survey (Imag...

ESO's Multi Unit Spectroscopic Explorer (MUSE) instrument, which is mounted on the Very Large Telescope based in the Paranal Observatory, Chile, has been focusing in on a tiny patch in the night sky previously featured in Hubble's Deep Field South image (HDF-S). After only 27 hours of continuous observation, the cutting edge instrument has captured detailed measurements of more galaxies with more detail than ever before.  Read More

The plume was discovered by telescopic observations (Image: W. Jaeschke and D. Parker)

Astronomers are scratching their heads over mysterious plumes that have been sighted in the atmosphere of Mars. First seen by amateur astronomers using Earthbound telescopes, the plumes are at an altitude much higher than that of any clouds yet seen on the Red Planet, and may not even be clouds.  Read More

NASA's Hubble Space Telescope has captured a rare image of a triple transit, as three of Jupiter's largest moons cast their shadows on the gas giant's planetary disk. The three moons captured in the image – Europa, Callisto and Io, were among the first celestial objects observed with a telescope, and were instrumental in debunking the long held belief that the Earth was at the center of the universe.  Read More
