Astronomers use Hubble to 'weigh' Dog Star's companion

13 December 2005: White dwarfs are important to theories of both stellar and cosmological evolution. New results published in the Monthly Notices of the Royal Astronomical Society provide for the first time an accurate measurement of the weight of the nearest white dwarf, Sirius B, companion of the brightest star in the sky. It turns out that Sirius's companion, despite being smaller than the Earth, has a mass that is 98% that of our own Sun.

Most detailed image of the Crab Nebula

1 December 2005: A new Hubble image - among the largest ever produced with the Earth-orbiting observatory - gives the most detailed view so far of the entire Crab Nebula. The Crab is arguably the single most interesting object, as well as one of the most studied, in all of astronomy. The image is the largest ever taken with Hubble's WFPC2 workhorse camera.

Young stars sculpt gas with powerful outflows

10 November 2005: This Hubble Space Telescope view shows one of the most dynamic and intricately detailed star-forming regions in space, located 210,000 light-years away in the Small Magellanic Cloud (SMC), a satellite galaxy of our Milky Way. At the centre of the region is a brilliant star cluster called NGC 346. A dramatic structure of arched, ragged filaments with a distinct ridge surrounds the cluster.

Spitzer and Hubble find a 'big baby' galaxy in the newborn Universe

27 September 2005: Two space observatories, NASA's Spitzer Space Telescope and the NASA/ESA Hubble Space Telescope, have teamed up to "weigh" the stars in several very distant galaxies. One of these galaxies is not only amongst the most distant ever seen, but it appears to be unusually massive and mature for its place in the young Universe. This has surprised astronomers because the earliest galaxies in the Universe are commonly thought to have been much smaller agglomerations of stars that gradually merged together later to build large majestic galaxies like our Milky Way.

Hubble finds mysterious disk of blue stars around a black hole

20 September 2005: Astronomers using the NASA/ESA Hubble Space Telescope have identified the source of a mysterious blue light surrounding a supermassive black hole in our neighbouring Andromeda Galaxy (M31). Though the light has puzzled astronomers for more than a decade, the new discovery makes the story even more mysterious.

Black hole in search of a home

14 September 2005: The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars. This is the first convincing discovery of such an object. One intriguing explanation is that the host galaxy may be made almost exclusively of dark matter.

FITS for fun - create spectacular pictures in minutes

8 August 2005: With the release of version 2 of the popular ESA/ESO/NASA Photoshop FITS Liberator image processing software it is now easier and faster than ever before to create colour images from raw observations from for instance the NASA/ESA Hubble Space Telescope, ESA's XMM-Newton and the NASA Spitzer Space Telescope.

Hubble captures Deep Impact's collision with a comet

4 July 2005: This series of Hubble Space Telescope images captures the ejection of a bright plume of dust following the July 4 collision between an 370 kilogram projectile released by the Deep Impact spacecraft and comet 9P/Tempel 1. The image sequence dramatically shows the evolution of material that was blasted off the comet as it expands and diffuses into interplanetary space.

Hubble captures outburst from comet targeted by Deep Impact

27 June 2005: In a dress rehearsal for the rendezvous between NASA's Deep Impact spacecraft and comet 9P/Tempel 1, the Hubble Space Telescope captured dramatic images of a new jet of dust streaming from the icy comet.

Supernova remnant menagerie

7 June 2005: A violent and chaotic-looking mass of gas and dust is seen in this Hubble Space Telescope image of a nearby supernova remnant. Denoted N 63A, the object is the remains of a massive star that exploded, spewing its gaseous layers out into an already turbulent region.

Hubble celebrates 15th anniversary with spectacular new images

25 April 2005: During the 15 years that the NASA/ESA Hubble Space Telescope has orbited the Earth, it has taken three-quarters of a million photos of the cosmos - images that have awed, astounded and even confounded astronomers and the public alike. Today NASA and ESA released new views of two of the most well-known images Hubble has ever taken: the Eagle Nebula, and spiral galaxy M51, known as the Whirlpool Galaxy.

Hubble's 15th Anniversary - an opportunity too good to miss!

14 April 2005: The NASA/ESA Hubble Space Telescope is one of the biggest scientific projects of all time and is approaching the 15th anniversary of its launch. To mark the event on 24 April, the European Space Agency is presenting a series of unique activities in collaboration with partners all over Europe. These includes an exclusive, full-length DVD film (one of the most widely distributed documentary films ever), a CD of the film soundtrack, a full-colour book and additional educational material. All over Europe, there will be Hubble Day events, press events and planetarium shows about Hubble.

Saturn's aurorae defy scientists' expectations

16 February 2005: The dancing light of the auroras on Saturn behaves in ways different from how scientists have thought possible for the last 25 years. New research by a team of US and European planetary scientists led by John Clarke of Boston University, USA, has overturned theories about how Saturn's magnetic field behaves and how its auroras are generated. Their results will be published in the February 17 issue of the journal Nature.

Light continues to echo three years after stellar outburst

3 February 2005: The Hubble Space Telescope's latest image of the star V838 Monocerotis (V838 Mon) reveals dramatic changes in the illumination of surrounding dusty cloud structures. The effect, called a light echo, has been unveiling never-before-seen dust patterns ever since the star suddenly brightened for several weeks in early 2002.

Hubble finds infant stars in neighbouring galaxy

12 January 2005: Hubble astronomers have uncovered, for the first time, a population of infant stars in the Milky Way satellite galaxy, the Small Magellanic Cloud (SMC, visible to the naked eye in the southern constellation Tucana), located 210,000 light-years away.

Hubble's infrared eyes home in on suspected extrasolar planet

10 January 2005: Unique follow up observations carried out with the NASA/ESA Hubble Space Telescope are providing important supporting evidence for the existence of a candidate planetary companion to a relatively bright young brown dwarf star located 225 light-years away in the southern constellation Hydra.
