Hubble Space Telescope Resolves Eruption of a Massive Star
Observations of a massive, unstable star called Eta Carinae, made with the Wide Field and Planetary Camera (WF/PC) aboard NASA's Hubble Space Telescope HST, reveal surprising and complex new structure in a dusty nebula surrounding the star. New details include a jet of material flowing away from the star and a regularly spaced set of wave-like features. The results are being reported on May 17, 1991 at the Hubble Space Telescope Science Writer's Workshop in Baltimore Md.

Hubble Space Telescope Establishes Accurate New Distance Measurement To Neighbouring Galaxy
Recent observations of the remnants of Supernova 1987A, conducted with NASA's Hubble Space Telescope have provided an unexpected bonus - an accurate determination of the absolute distance to the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located in the southern hemisphere.

Hubble Space Telescope Resolves Braided Galactic Jet
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.

Hubble Space Telescope Probes a Galaxy with an Active Nucleus
The NASA/ESA Hubble Space Telescope has provided an unprecedented, detailed view of highly energetic events in the core of a galaxy 30 million light-years away. The observations are a first step in HST's search for super-massive black holes at the nuclei of active galaxies.

R Aquarii - A Nearby Exploding Star
The NASA/ESA Hubble Space Telescope has peered into the inner core of the nearby so-called "symbiotic star", R Aquarii, to reveal dramatic new details of the exploding star. The observations were made with the European Space Agency's Faint Object Camera.

Hubble Space Telescope Photographs Extragalactical Stellar Nursery
NASA is releasing a Hubble Space Telescope (HST) photograph of the most remarkable star forming region in the Local Group of Galaxies, 30 Doradus. The photograph shows about 60 stars within a central tight cluster in 30 Doradus. In contrast, earlier photographs with ground-based telescopes, supplemented by mathematical analysis, have shown only 27 stars in the tight cluster, which is called R136. Before the ground-based studies showed that so many stars are present in R136, some astronomers thought it was a single, supermassive object, with as much as 3000 times the mass of the Sun.

ESA's Faint Object Camera First Images
The European Space Agency's Faint Object Camera aboard NASA's Hubble Space Telescope has successfully taken its first engineering test pictures of the heavens. This "first light" picture for the Faint Object Camera (FOC) is the culmination of several weeks of intensive check-out and testing of the camera, following the launch of the Hubble Space Telescope (HST) last April 24.
