title First ESA Faint Object Camera Science Images Pluto - the "Double Planet
description NASA's Hubble Space Telescope has obtained the clearest pictures ever of our solar system's most distant and enigmatic object: the planet Pluto. The observations were made with the European Space Agency's Faint Object Camera. *Image Credit*: NASA and ESA
Pluto's Surface
title Pluto's Surface
description Images of Pluto taken by the NASA Hubble Space Telescope with the ESA Faint Object Camera. These images, taken in late June and early July, 1994 are the first views which allow resolution of features on Pluto's surface. Opposite hemispheres are seen on the left and right. The large lower images are processed versions made from a number of Hubble observations. The smaller images at the top are actual raw images, each pixel is over 150 km across. The variations in brightness may be due to topographic features and/or surface composition, frost layers, and interactions with Pluto's nitrogen-methane atmosphere. Pluto is 2390 km in diameter and north is up.
Pluto Surface Map
title Pluto Surface Map
description Surface map of Pluto constructed from four images taken by the ESA Faint Object Camera of NASA's Hubble Space Telescope. The images were taken in late June and early July as Pluto rotated through its 6.5 day period. The map shows a very coarse view of Pluto's surface, but reveals light and dark areas which may be indicative of differences in topography and/or surface materials and frosts. *Image Credit*: NASA

Pluto and Charon
title Pluto and Charon
date 02.21.1994
description This is the clearest view yet of the distant planet Pluto and its moon, Charon, as revealed by NASA's Hubble Space Telescope (HST). The image was taken by the European Space Agency's Faint Object Camera on February 21, 1994 when the planet was 4.4 billion kilometers (2.6 billion miles) from Earth, or nearly 30 times the separation between Earth and the Sun. Hubble's corrected optics show the two objects as clearly separate and sharp disks. This now allows astronomers to measure directly (to within about 1 percent) Pluto's diameter of 1440 miles (2320 kilometers) and Charon's diameter of 790 miles (1270 kilometers). The Hubble observations show that Charon is bluer than Pluto. This means that both worlds have different surface composition and structure. A bright highlight on Pluto suggests it has a smoothly reflecting surface layer. A detailed analysis of the Hubble image also suggests there is a bright area parallel to the equator on Pluto. This result is consistent with surface brightness models based on previous ground-based photometric observations. However, subsequent HST observations will be required to confirm whether the feature is real. Though Pluto was discovered in 1930, Charon wasn't detected until 1978. That is because the moon is so close to Pluto that the two worlds are typically blurred together when viewed through ground-based telescopes. (If our moon were as close to Earth, it would be as big in the night sky as an apple held at arm's length). The new HST image was taken when Charon was near its maximum elongation from Pluto of .9 arc seconds. The two worlds are 12,200 miles apart (19,640 kilometers). Hubble's ability to distinguish Pluto's disk at a distance of 2.6 billion miles (4.4 billion kilometers) is equivalent to seeing a baseball at a distance of 40 miles (64 kilometers). Pluto typically is called the double planet because Charon is half the diameter of Pluto (our Moon is one-quarter the diameter of Earth). *Image Credit*: Dr. R.

Title 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.

Title Hubble Provides Clearest View Yet of Supernova 1987a
General Information What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. This series of images of Supernova 1 987A was taken with ESA's Faint Object Camera aboard NASA's Hubble Space Telescope, prior to and following the HST Servicing Mission. The images demonstrate the dramatic improvement in Hubble's capabilities following the installation of the Corrective Optics Space Telescope Axial Replacement (COSTAR), which compensates for spherical aberration in Hubble's primary mirror. The new picture has provided the most detailed closeup view ever obtained of the exploding star and its surroundings. Since SNi1987A first appeared in the southern sky nearly seven years ago (February 24, 19871, the outer envelope of the exploding star has been expanding into space at many thousands of kilometers per second. To follow the evolution of the ejecta, astronomers have observed SN 1 987A a total of six times with the FOC -- from just after HST's launch in 1990 to just before the HST Servicing mission in December 1993.

Title Hubble Space Telescope Captures First Direct Image of a Star
General Information What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. This is the first direct image of a star other than the Sun. Called Alpha Orionis, or Betelgeuse, the star is a red super giant, a Sun-like star nearing the end of its life. The Hubble picture reveals a huge ultraviolet atmosphere with a mysterious hot spot on the stellar behemoth's surface. The enormous bright spot, twice the diameter of the Earth's orbit, is at least 2,000 degrees Kelvin hotter than the star's surface.

General Information What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. NASA's Hubble Space Telescope has provided a detailed view of a ten thousand light-year long jet of plasma which has been ejected from the core of a galaxy 270 million light-years away. Observations made with the European Space Agency's Faint Object Camera (FOC) reveal that the jet has an unusual braided structure, like a twisted pair of wires. "This is the first time that such a structure has been seen in an optical jet," says F. Duccio Macchetto, ESA's Principal Investigator on the FOC and Head of the Science Programs Division at the Space Telescope Science Institute.

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 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.

Title Motion in the R-Aquarii Jet 1991, 1992, 1993: 2-D Motion
Abstract Images from the Hubble Space Telescope's Faint Object Camera from 1991, 1992, and 1993 demonstrate motion in the R Aguarii emission jet. Since images from this period were still affected by the primary mirror flaw, the images were restored to the original design resolution using the maximum entropy method.
