The Many Faces of Vesta: To prepare for the Dawn spacecraft's visit to Vesta, astronomers used Hubble's Wide Field Planetary Camera 2 to snap new images of the asteroid. These images were taken on May 14 and 16, 2007. Each frame shows time in hours and minutes based on Vesta's 5.34-hour rotation period. Using Hubble, astronomers mapped Vesta's southern hemisphere, a region dominated by a giant impact crater formed by a collision billions of years ago. The crater is 285 miles (456 kilometres) across, which is nearly equal to Vesta's 330-mile (530-kilometre) diameter.

Hubble Captures Stars Going Out in Style: The colourful, intricate shapes in these NASA Hubble Space Telescope images reveal how the glowing gas ejected by dying Sun-like stars evolves dramatically over time. These gaseous clouds, called planetary nebulae, are created when stars in the last stages of life cast off their outer layers of material into space. The snapshots of HE 2-47, NGC 5315, IC 4593, and NGC 5307 were taken with Hubble's Wide Field Planetary Camera 2 in February 2007.

"Death star" galaxy black hole fires at neighboring galaxy: A powerful jet from a supermassive black hole is blasting a nearby galaxy, according to new data from NASA/ESA observatories. This never-before witnessed galactic violence may have a profound effect on planets in the jet's path and trigger a burst of star formation in its destructive wake.  Known as 3C 321, the system contains two galaxies in orbit around each other. Data from NASA's Chandra X-ray Observatory show both galaxies contain supermassive black holes at their centres, but the larger galaxy has a jet emanating from the vicinity of its black hole. The smaller galaxy apparently has swung into the path of this jet. This "death star galaxy" was discovered through the combined efforts of both space and ground-based telescopes. NASA's Chandra X-ray Observatory, NASA/ESA Hubble Space Telescope, and NASA's Spitzer Space Telescope were part of the effort. The Very Large Array (VLA) in Socorro, New Mexico (USA), and the Multi-Element Radio Linked Interferometer Network (MERLIN) telescopes in the United Kingdom also were needed for the finding.

Multi-panel image of 3C 321: A powerful jet from a supermassive black hole is blasting a nearby galaxy in the system known as 3C 321, according to new results from NASA/ESA. This galactic violence, never seen before, could have a profound effect on any planets in the path of the jet and trigger a burst of star formation in the wake of its destruction.

Quasar MC2 1635+119 and host galaxy: This image taken by Hubble shows the host galaxy of the quasar MC2 1635+119. The quasar sits in an indisturbed elliptical galaxy which shows a shell structure indicating a recent merger. An intermediate population of stars is dominating the galaxy and probably the result of a strong star burst at the time of the merging process.
