Jupiter, like Earth, has auroras at its poles. Thanks to new instruments on the Hubble Space Telescope and a specially designed filter, University of Michigan astrophysicists have produced the best images yet of this planetary phenomenon---pictures which should give researchers a much better understanding of Jupiter and its moons.
Space observations of some of the tiniest stars in the cosmos--reported Jan. 7, 1998 by University of Delaware researchers and their Danish collaborators at the American Astronomical Society meeting--have finally confirmed a Nobel Prize-winning theory on the structure of stars. The information is central to understanding pulsars, black holes and white dwarf stars.
Using a potent combination of observation and theory, astronomers are peeling away layers of cosmic dust to see the birth pains of sun-like stars.

The region's area-weighted monthly average temperature was 2.9 degrees cooler than normal, making it the 21st coolest November in the last 103 years.
Rates of atmospheric mercury deposition in Maine appear to have reached a peak in the early to mid-1970s and to have declined significantly by 1982, according to a report by University of Maine geologists published in the December issue of the journal Water, Air and Soil Pollution (v. 100: 271-186, 1997). Stephen A. Norton, Gordon C. Evans and Steve Kahl of the UMaine Department of Geological Sciences used archived cores from Sargent Mountain Pond and Big Heath in Acadia National Park on Mt. Desert Island to determine historical trends in mercury deposition from the atmosphere to the Maine landscape. The cores were collected in 1982 and 1983.
