Spotlight On AAS News

The following are results presented during the Winter 1998 American Astronomical Society (AAS) meeting that have used data obtained from the HST and other missions.

Hubble Provides Complete View Of Jupiter's Auroras
NASA's Hubble Space Telescope has captured a complete view of Jupiter's northern and southern auroras.

Hubble Finds Most Of Visible Light In The Universe
A closer look at the Hubble Space Telescope's most detailed image, the Hubble Deep Field, reveals that the faint galaxies seen by Hubble could account for most of the visible light in the cosmos.

New Twist In A Suspected Protoplanetary Disk
These two Hubble Space Telescope visible-light views of the edge- on disk of dust around the star Beta Pictoris yield telltale evidence for the existence of planets, and possibly the gravitational tug of a companion brown dwarf or bypassing star.

Hubble Provides Clear Images Of Saturn's Aurora
This is the first image of Saturn’s ultraviolet aurora taken by the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope in October 1997, when Saturn was a distance of 810 million miles (1.3 billion kilometers) from Earth.

Distant Exploding Stars Foretell Fate Of The Universe
New studies of exploding stars in the farthest reaches of deep space indicate that the universe will expand forever, according to findings of the Supernova Cosmology Project, an international team of astrophysicists based at the Department of Energy's Ernest Orlando Lawrence Berkeley National Laboratory.

Hubble Pinpoints Distant Supernovae
These Hubble Space Telescope images pinpoint three distant supernovae, which exploded and died billions of years ago. Scientists are using these faraway light sources to estimate if the universe was expanding at a faster rate long ago and is now slowing down.

Infrared Background Glow in The Universe
Astronomers have assembled the first definitive detection of a background infrared glow across the sky produced by dust warmed by all the stars that have existed since the beginning of time.

A New Class Of X-ray Star?
Teaming up space telescopes to make simultaneous ultraviolet and X-ray observations, astronomers may have solved a 20-year old mystery and possibly discovered a new class of X-ray star.

Dust in Spiral Galaxies
New images presented today from a pair of satellite telescopes offer a unique view of the obscuring dust in galaxies, taking advantage of rare cosmic silhouettes to help resolve a debate about how much of this dust exists in galaxies, where it is, and how much it matters.
