News Release: Hubble assists Rosetta comet mission [heic0310]
Results from the HST played a major role in preparing ESA’s ambitious Rosetta mission for its new target, comet 67P/ Churyumov-Gerasimenko. Hubble measured precisely the size, shape and rotational period of the comet.

Finding the ashes of the first stars [heic0306]
Recent observations with the Hubble Space Telescope suggest that the first stars formed as little as 200 million years after the Big Bang. This is much earlier than previously thought. Astronomers have observed large amounts of iron in the ultraluminous light from very distant, ancient quasars. This iron is the 'ashes' left from supernova explosions in the very first generation of stars.

A perfect storm of turbulent gases [heic0305]
Like the fury of a raging sea, this anniversary image from the NASA/ESA Hubble Space Telescope shows a bubbly ocean of glowing hydrogen, oxygen, and sulphur gas in the extremely massive and luminous molecular nebula Messier 17.

Hubble watches light echo from mysterious erupting star [heic0304]
In January 2002, a moderately dim star in the constellation Monoceros, the Unicorn, suddenly became 600 000 times more luminous than our Sun. This made it temporarily the brightest star in our Milky Way. The light from this eruption created a unique phenomenon known as a 'light echo' when it reflected off dust shells around the star.

European astronomers observe first evaporating planet [heic0303]
Using the Hubble Space Telescope, for the first time, astronomers have observed the atmosphere of an extrasolar planet evaporating off into space. Much of this planet may eventually disappear, leaving only a dense core. The planet is a type of extrasolar planet known as a 'hot Jupiter'. These giant, gaseous planets orbit their stars very...

Hubble resolves a blaze of stars in galaxy's core [heic0302]
The central region of the small galaxy NGC 1705 blazes with the light of thousands of young and old stars. Astronomers call NGC 1705 a dwarf irregular, that is, a small galaxy lacking regular structure. Knowing how dwarf irregular galaxies evolve tells us a lot about galaxy formation and evolution.

The Boomerang Nebula - the coolest place in the Universe? [heic0301]
The Boomerang Nebula is a young planetary nebula and the coldest object found in the Universe so far. The NASA/ESA Hubble Space Telescope image illustrates how Hubble's keen vision reveals surprises in celestial objects.

First light for Europe's virtual observatory
Imagine you are an astronomer with instant, fingertip access to all existing observations of a given object and the opportunity to sift through them at will. In just a few moments, you can have information on all kinds about objects out of catalogues all over the world, including observations taken at different times.

Missing link found between supernovae and black holes [heic0211]
A nearby black hole, hurtling like a cannonball through the plane of our Milky Way, has provided possibly the best evidence yet that stellar-mass black holes are made in supernova explosions. This black hole is streaking across space at a rate of 400 000 kilometres per hour - 4 times faster than the average velocity of the stars in the galactic neighbourhood. What has made it move so fast? The most likely 'cannon' is the explosive kick of a supernova, one of the Universe's most titanic events.

A rose blooming in space [heic0210]
Resembling a delicate rose floating in space, the nebula N11A is seen in a new light in a true-colour image taken by the NASA/ESA Hubble Space Telescope. Fierce radiation from massive stars embedded at the centre of N11A illuminates the surrounding gas with a soft fluorescent glow.

A glimpse into the heart of a dying star [heic0209]
An image taken with the NASA/ESA Hubble Space Telescope shows one of the most unusually long planetary nebulae found so far. Scientists think planetary nebulae hold the key to understanding how the Universe became enriched with heavier elements so they study them intensively. It is not well-understood how a perfectly round star can turn into such an unusual-looking nebula.

Young stars in old galaxies - surprising discovery with the world's leading telescopes [heic0208]
Combining data from the NASA/ESA Hubble Space Telescope and the ESO Very Large Telescope (VLT), a group of European and American astronomers have made a major discovery. They have identified a huge number of 'young' stellar clusters, in an old elliptical galaxy. For the first time, it has been possible to identify several distinct periods of star formation in a galaxy as old as this one. Elliptical galaxies have always been considered to have undergone one early star-forming period and thereafter to be devoid of star formation. However, the combination of the best and largest telescopes in space and on the ground has now clearly shown that there is more than meets the eye.
