Vampires and collisions rejuvenate stars

23 December 2009: Using the NASA/ESA Hubble Space Telescope, astronomers have uncovered two distinct kinds of "rejuvenated" stars in the globular cluster Messier 30. A new study shows that both stellar collisions and a process sometimes called vampirism are behind this cosmic "face lift". The scientists also uncover evidence that both sorts of blue stragglers were produced during a critical dynamical event (known as "core collapse") that occurred in Messier 30 a few billion years ago.

Born in beauty: proplyds in the Orion Nebula

14 December 2009: A collection of 30 never-before-released images of embryonic planetary systems in the Orion Nebula are the highlight of the longest single Hubble Space Telescope project ever dedicated to the topic of star and planet formation. Also known as proplyds, or protoplanetary discs, these modest blobs surrounding baby stars are shedding light on the mechanism behind planet formation. Only the NASA/ESA Hubble Space Telescope, with its high resolution and sensitivity, can take such detailed pictures of circumstellar discs at optical wavelengths.

Hubble's deepest view of Universe unveils never-before-seen galaxies

8 December 2009: The new Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope has taken the deepest image yet of the Universe in near-infrared light. The faintest and reddest objects in the image are likely the oldest galaxies ever identified, having formed between only 600–900 million years after the Big Bang.

Blushing dusty nebula

1 December 2009: A recent NASA/ESA Hubble Space Telescope image of part of NGC 7023, or the Iris Nebula, highlights a perfect dust laboratory in the sky.

Baffling boxy bulge

18 November 2009: Just as many people are surprised to find themselves packing on unexplained weight around the middle, astronomers find the evolution of bulges in the centres of spiral galaxies puzzling. A recent NASA/ESA Hubble Space Telescope image of NGC 4710 is part of a survey that astronomers have conducted to learn more about the formation of bulges, which are a substantial component of most spiral galaxies.

Opening up a colourful cosmic Jewel Box

29 October 2009: The combination of images taken by three exceptional telescopes: the NASA/ESA Hubble Space Telescope, the ESO Very Large Telescope on Cerro Paranal, the MPG/ESO 2.2-metre telescope at ESO’s La Silla observatory has allowed the stunning Jewel Box star cluster to be seen in a whole new light.

Sky merger yields sparkling dividends

13 October 2009: A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies that resemble our own Milky Way smashing together at breakneck speeds. The product of this dramatic collision, called NGC 2623, or Arp 243, is about 250 million light-years away in the constellation of Cancer (the Crab).

Stripped down: Hubble highlights two galaxies that are losing it

30 September 2009: A newly released set of images, taken by the NASA/ESA Hubble Space Telescope before the recent Servicing Mission, highlight the ongoing drama in two galaxies in the Virgo Cluster affected by a process known as "ram pressure stripping", which can result in peculiar-looking galaxies. An extremely hot X-ray emitting gas known as the intra-cluster medium lurks between galaxies within clusters. As galaxies move through this intra-cluster medium, strong winds rip through galaxies distorting their shape and even halting star formation.

Rebirth of an icon: Hubble's first images since Servicing Mission 4

9 September 2009: Astronomers today declared the NASA/ESA Hubble Space Telescope a fully rejuvenated observatory ready for a new decade of exploration, with the release of observations from four of its six operating science instruments.

Hubble captures rare Jupiter collision

24 July 2009: The checkout and calibration of the NASA/ESA Hubble Space Telescope has been interrupted to aim the recently refurbished observatory at a new expanding spot on the giant planet Jupiter. The spot, caused by the impact of a comet or an asteroid, is changing from day to day in the planet’s cloud tops.

Historic Hubble Servicing Mission 4 ends with successful landing

24 May 2009: The historic and successful Hubble Servicing Mission 4 concluded with a trouble-free Space Shuttle landing on Sunday. During a series of unprecedented spacewalks, astronauts replaced and repaired a total of four instruments. The Wide Field Camera 3 and Cosmic Origins Spectrograph were installed and the Advanced Camera for Surveys and Space Telescope Imaging Spectrograph were successfully repaired.

Servicing Mission 4 - the fifth and final visit to Hubble

1 May 2009: On 11 May 2009 the Space Shuttle Atlantis will launch with a crew of seven to visit the NASA/ESA Hubble Space Telescope and carry out the fifth and final servicing mission. The replacement and repair of several instruments will see Hubble equipped to continue its programme of discovery well into the next decade.

Hubble celebrates 19th anniversary with fountain of youth

21 April 2009: To commemorate the NASA/ESA Hubble Space Telescope's 19 years of success, the orbiting telescope has photographed a peculiar system of galaxies known as Arp 194. This interacting group contains several galaxies along with a "cosmic fountain" of stars, gas and dust that stretches over 100 000 light years.

The NASA/ESA Hubble Space Telescope provides new evidence for dark matter around small galaxies

12 March 2009: The NASA/ESA Hubble Space Telescope has uncovered a strong new line of evidence that galaxies are embedded in halos of dark matter.

Stars forced to relocate near the Southern Fish

3 March 2009: A new Hubble image shows three galaxies locked in a gravitational tug-of-war that may result in the eventual demise of one of them.

Exceptionally deep view of strange galaxy

5 February 2009: A spectacular new image of an unusual spiral galaxy in the Coma Galaxy Cluster has been created from data taken by the Advanced Camera for Surveys on the NASA/ESA Hubble Space Telescope. It reveals fine details of the galaxy, NGC 4921, as well as an extraordinary rich background of more remote galaxies stretching back to the early Universe.
