Hubble's stunning near-infrared image of the Horsehead Nebula (Image: NASA)

New near-infrared and far-infrared views captured by NASA's Hubble Space Telescope and the European Space Agency's Herschel space telescope have provided a spectacular new look at the famous Horsehead Nebula.  Read More

August 31, 2012: A solar filament erupts out into space (Image: NASA/GSFC/SDO)

2012 saw a number of significant milestones in star gazing and space exploration. NASA's Mars rover Curiosity touched down on the Red Planet in spectacular fashion, super-Earth's were discovered, the Moon pounded and Voyager 1 edged ever closer towards interstellar space. We also saw more of the universe around us than ever before and as usual, NASA treated us to an array of incredible images.  Read More

The galaxy NGC 1277 as photographed by the Hubble Space Telescope

Astronomers from the University of Texas at Austin have measured the second-largest black hole ever discovered. It takes up some 14 percent of the galaxy's mass and may lead to an overhaul of theories regarding the formation and evolution of black holes.  Read More

Distant galaxy lensed by Cluster MACS J0647 (Image: NASA)

NASA's Hubble telescope has discovered the most distant object yet seen in the universe. The object, a galaxy called MACS0647-JD, is 13.3 billion light years from Earth and can only be seen with the help of a lens of intergalactic proportions. The light from MACS0647-JD left it only 420 million years after the Big Bang, so it provides a valuable look into the nature of the early universe.  Read More

The Spitzer space telescope has peered through dust and gas to establish a new value for t...

The size and age of our Universe is not only a critically important issue in cosmology, but is also among the most controversial and delicate of the cosmological questions. Infrared observations made using NASA's Spitzer Space Telescope have now given us the most precise estimate yet of the rate at which our Universe is expanding. The key was not the discovery of a new method for measuring distance. Rather, astronomers discovered how to measure brightness more accurately. The new value for the Hubble constant, good to within three percent, is 74.3 kilometers per second per megaparsec (km/s/Mpc).  Read More

Astronomers have assembled a new, improved portrait of our deepest-ever view of the Univer...

NASA scientists have directed the Hubble Space Telescope to inspect a tiny patch of sky with an unusually long exposure time to obtain the deepest image of the sky ever obtained. The image, dubbed the Hubble Extreme Deep Field (XDF), reveals the faintest and most distant galaxies ever detected, shedding more light on the early history of the universe.  Read More

Light from the primordial galaxy, dubbed 'MACS 1149-JD', traveled approximately 13.2 billi...

A team of Johns Hopkins University astronomers have spotted what may well be the most distant galaxy ever detected. Dubbed "MACS 1149-JD", the discovery provides insight into the most remote epoch of cosmic history, as light captured from the faint galaxy shone forth when the universe was just 500 million years old – or 3.6 percent of its present age.  Read More

When astronomers used the Hubble Space Telescope to scout a remote patch of the sky and investigate the early stages of galaxy formation, they stumbled upon something which they did not expect. They realized that the distant spiral galaxy BX422, appearing to us as it was only three billion years after the Big Bang, seems to be uncharacteristically well-formed for its young age. By studying its features, which are in direct contrast with our current knowledge of galaxy formation, scientists hope to shed more light on how spiral galaxies – including our own – are formed.  Read More

Pluto may no longer be classified as a planet, but that doesn’t mean it isn’t still getting its fair share of attention. NASA’s New Horizons spacecraft is currently making its way to the icy dwarf planet to study it and its moons. To search for potential hazards to the spacecraft and help plan a safer trajectory before its scheduled arrival in 2015, a team of astronomers has trained the eye of the Hubble Space Telescope on the system and discovered a fifth, previously unknown moon orbiting the planet.  Read More

3.75 billion years from now - the nighttime sky showing the Andromeda galaxy (M31) early i...

When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). The collision will start in about four billion years, and over the following three billion years the two spiral galaxies will coalesce into a large elliptical galaxy. Based on this data, NASA has produced a video of the upcoming collision.  Read More
