Hubble's new improved optics probe the core of a distant galaxy
Release date: January 13, 1994
A comparison image of the core of the galaxy M100 shows the dramatic improvement in Hubble's view of the universe. The new image (right) was taken with the second generation Wide Field and Planetary Camera which was installed during the 1993 Servicing Mission.
NASA and Congress commit funding for four astronomical satellites—the Hubble Space Telescope (HST), the Compton Gamma Ray Observatory (CGRO), the Spitzer Space Telescope, and the Chandra X-ray Observatory—to fly under the Great Observatories banner. NASA's astrophysics director Charlie Pellerin had conceived of the “Great Observatories” program; envisioning four large space telescopes operating simultaneously to cover a large swath of the electromagnetic spectrum.

The spacecraft, after collecting radar images of 98 percent of the planet's surface, makes a dramatic conclusion to its highly successful mission. It is commanded to plunge into the dense atmosphere of Venus to gain data on the planet's atmosphere and on the performance of the spacecraft as it descended.
Magellan spacecraft radar data enabled scientists to penetrate Venus' thick clouds and create simulated views of the surface.
