Galaxy M100 Resolution Comparison |
| General Information |
What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. This sequence of pictures shows successive steps in optical improvement from ground based telescopes to the newly improved Hubble Space Telescope and demonstrates the unique capability of the repaired HST. HST offers superb resolution, which allows astronomers to distinguish individual afar. in other galaxies. The resolution also allows very faint stars to be seen. This set of pictures demonstrates that the repaired HST can see stars which could never before be detected. |

Hubble's Improved Optics Reveal Incredible Detail in Giant Cloud of Gas and Dust |

What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. An image of a star-forming region in the 30 Doradus nebula, surrounding the dense star cluster R136. The image was obtained using the second generation Wide Filed and Planetary Camera (WFPC-2), installed in the Hubble Space Telescope during the STS-61 Servicing Mission. The WFPC-2 contains modified optics to correct for the aberration of the Hubble's primary mirror. The new optics will allow the telescope to tackle many of the most important scientific programs for which the it was built, but had to be temporarily shelved with the discovery of the spherical aberration in 1990. |

Hubble Sees Changes in Gas Shell around Nova Cygni 1992 |
| General Information |
What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. The Hubble telescope has given astronomers their best look yet at a rapidly ballooning bubble of gas blasted off a star. The shell surrounds Nova Cygni 1992, which erupted Feb. 19, 1992. A nova is a thermonuclear explosion that occurs on the surface of a white dwarf star in a double-star system. The image [right], taken after Hubble's near-sightedness had been corrected, reveals an elliptical and slightly lumpy ring-like structure. The ring is the edge of a bubble of hot gas blasted into space by the nova. Another Hubble picture taken 467 days after the explosion [left] provided the first glimpse of the ring and a mysterious bar-like structure. But the image interpretation was severely hampered by the telescope's blurred vision. |

Picture Perfect: Hubble's New Improved Optics Probe the Core of a Distant Galaxy |
| General Information |
What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. This comparison image of the core of galaxy M100 shows the dramatic improvement in the Hubble telescope's view of the universe. The new image (right) was taken with the second generation Wide Field and Planetary Camera (WFPC2), which was installed during the STS-61 Hubble Servicing Mission. The picture beautifully demonstrates that the corrective optics incorporated within WFPC2 compensate fully for Hubble's near-sightedness. The new camera will allow Hubble to probe the universe with unprecedented clarity and sensitivity. The picture clearly shows faint structure as small as 30 light-years across in a galaxy tens of millions of light-years away. |

The Spiral Galaxy M100 as Seen With the Hubble's Improved Vision |
| General Information |
What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. An image of the grand design spiral galaxy M100 obtained with the second generation Wide Field and Planetary Camera (WFPC-2), newly installed in the Hubble Space Telescope. Though the galaxy lies several tens of millions of light-years away, modified optics incorporated within the WFPC-2 allow Hubble to view M100 with a level of clarity and sensitivity previously possible only for the very few nearby galaxies that compose our "Local Group." Just as one does not learn about the diversity of mankind by conversing only with your next door neighbor, astronomers must study many galaxies in a host of different environments if they are to come to understand how our own galaxy, out star, and our earth came to be. By expanding the region of the universe that can be studied in such detail a thousand fold, the WFPC-2 will help the Hubble Space Telescope to fulfill this mission. |

What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. This pair of images of a single star, taken with the European Space Agency's Faint Object Camera (FOC), demonstrate that NASA's Hubble Space Telescope has been restored fully to its planned optical performance. The COSTAR mirrors remove the effect of spherical aberration in the HST's primary mirror. The FOC will now be able to observe extremely faint celestial objects with a clarity and sensitivity unmatched by ground-based telescopes. |
