A New Angle on Two Spiral Galaxies for Hubble's 27th Birthday

When the Hubble Space Telescope launched aboard the Space Shuttle Discovery on April 24, 1990, astronomers could only dream what they might see. Now, 27 years and more than a million observations later, the telescope delivers yet another magnificent view of the universe this time, a striking pair of spiral galaxies much like our own Milky Way. These island cities of stars, which are approximately 55 million light-years away, give astronomers an idea of what our own galaxy would look like to an outside observer. The edge-on galaxy is called NGC 4302, and the tilted galaxy is NGC 4298. Although the pinwheel galaxies look quite different because they are angled at different positions on the sky, they are actually very similar in terms of their structure and contents.

The 20th Anniversary of the Hubble Space Telescope's STIS Instrument

Twenty years ago, astronauts on the second servicing mission to the Hubble Space Telescope installed the Space Telescope Imaging Spectrograph (STIS) aboard Hubble. This pioneering instrument combines a camera with a spectrograph, which provides a "fingerprint" of a celestial object's temperature, chemical composition, density, and motion. STIS also reveals changes in the evolving universe and leads the way in the field of high-contrast imaging.

NASA and ESA are celebrating the Hubble Space Telescope's silver anniversary of 25 years in space by unveiling some of nature's own fireworks - a giant cluster of about 3,000 stars called Westerlund 2. The cluster resides inside a vibrant stellar breeding ground known as Gum 29, located 20,000 light-years away in the constellation Carina. The comparatively young, 2-million-year-old star cluster contains some of our galaxy's hottest, brightest, and most massive stars. The largest stars are unleashing a torrent of ultraviolet light and hurricane-force winds that etch away the enveloping hydrogen gas cloud. This creates a fantasy celestial landscape of pillars, ridges, and valleys.

Scientists say they have every hope that the Hubble Space Telescope will keep working for at least another five years, perhaps more.
The famous observatory is about to celebrate its 25th birthday.

 European Hubble archive moves to Spain

The European science archive for the NASA/ESA Hubble Space Telescope has been transferred to ESA's European Space Astronomy Centre (ESAC) in Villanueva de la Cañada near Madrid, Spain.
This guarantees a permanent home for Hubble science data following the closure of the Space Telescope European Coordinating Facility (ST-ECF), located at the headquarters of the European Southern Observatory near Munich, Germany.
