Ulysses Radio Tracking from High Solar Latitudes and the Interplanetary Magnetic Field Topology

"Snapshot" of the spiral shape of the interplanetary magnetic field, as obtained from radio observations from the interplanetary spacecraft Ulysses. This view from the north ecliptic pole is based on Ulysses radio measurements made as it was passing over the Sun's south pole. The white symbols represent the actual observations of the location of outward moving streams of electrons, ejected from the Sun on Oct. 25 and Oct. 30, 1994. The numbers indicate the frequency of radio emission, so that "740" represents emission at a radio frequency of 740 kilohertz. The planets Mercury, Venus, and Earth are shown in their approximate true positions at the time of observation; the large orange circles illustrate their orbits around the Sun. A yellow arrow points out the location of the Sun where a solar flare explosion at 10:15 UT. On October 25, 1994 ejected the electrons tracked by Ulysses on that date. The spiral blue lines illustrate the shape of the magnetic field as predicted from theory for a constant solar wind speed. PHOTO CREDIT: NASA's Goddard Space Flight Center.

OAST-Flyer

Goddard's OAST-Flyer currently is manifested Space Shuttle Endeavour on Mission STS-72 scheduled for to flight January 11, 1996. OAST-Flyer, the seventh Spartan to fly, is composed of four experiments: Return Flux Experiment (REFLEX), Global Positioning System (GPS) Attitude Determination and Control Experiment (GADACS), Solar Exposure to Laser Ordnance Device (SELODE), and Spartan Packet Radio Experiment (SPRE). Three of the four experiments are sponsored by the Office of Space Access and Technology (OSAT). The fourth experiment, SPRE, is a volunteer effort comprised of University of Maryland students, area engineers, and space industry contractors.

MILKY WAY

This image of our galaxy, the Milky Way, was taken with NASA's Cosmic Background Explorer (COBE)'s Diffuse Infrared Background Experiment (DIRBE), one of three COBE scientific instruments.

SPIRAL GALAXY MESSIER 101

This ultraviolet image of the giant spiral galaxy Messier l01 (M101) was obtained by the Ultraviolet Imaging Telescope during the Astro-2 mission of the Space Shuttle Endeavour.

STAR CLUSTERS IN THE LARGE MAGELLANIC CLOUD

This arc of hot stars in the star-forming region N 51 in the Large Magellanic Cloud (LMC) was photographed by NASA's Ultraviolet Imaging Telescope (UIT) during the Astro-2 mission of Space Shuttle Endeavour, March 2-18, 1995. The LMC is about 160,000 light- years from the Earth, and appears in the constellation Dorado, which is visible from the Earth's southern hemisphere.

NGC6752 HIGHLIGHTS EVOLVING STARS

The globular cluster NGC 6752, in the southern constellation of Pavo, as seen in ultraviolet light at a wavelength of 1620 Angstroms with the Ultraviolet Imaging Telescope (UIT). The photograph was obtained on March 13, 1995, during the Astro-2 mission of the Space Shuttle Endeavour.

A MOSAIC OF FOUR ULTRAVIOLET IMAGES

This is a mosaic of four ultraviolet photographs of the Small Magellanic Cloud obtained on both the Astro-1 mission (December 1990) and the Astro-2 mission (March 1995).

THE STARBURST GALAXY NGC4736

A remarkable giant ring of hot young stars appears in the ultraviolet image (top) of the spiral galaxy Messier 94 (M94, also called NGC 4736), as photographed by the Ultraviolet Imaging Telescope on March 12, 1995, during the Astro-2 mission of the Space Shuttle Endeavour.

In red light (bottom), M94 shows three distinct zones: an extremely bright central bulge, composed mostly of old, cool stars; the main disk showing many short spiral arms; and an extensive, faint outer ring. The image made with a 36-inch (0.9 meter) telescope at Kitt Peak National Observatory.

PLANETARY NEBULA

This color picture, taken with the Wide Field Planetary Camera-2, is a composite of three images taken at different wavelengths. (red, hydrogen-alpha; blue, neutral oxygen, 6300 angstroms; green, ionized nitrogen, 6584 angstroms). The image was taken on September 18, 1994. The "Cat's Eye Nebula", one of the most complex planetary nebulae ever seen is 3,000 light years away in the northern constellation Draco.

JETS FROM YOUNG STARS

These NASA Hubble Space Telescope views of gaseous jets from three newly forming stars show a new level of detail in the star formation process, and are helping to solve decade-old questions about the secrets of star birth. Jets are a common "exhaust product" of the dynamics of star formation. They are blasted away from a disk of gas and dust falling onto an embryonic star.

HST MULTIPLE COMET IMPACT

NASA's Hubble Space Telescope resolves eight impact sites on Jupiter from the collisions of the fragmented comet, Shoemaker-Levy 9. This image was taken on July 22, 1994, shortly before the last comet fragment plunged into Jupiter's atmosphere. The impact sites appear as dark "smudges" lined up in Jupiter's southern hemisphere. The smudges are chemical debris cooked in the tremendous fireballs produced by each impact. The dark material was ejected high above the bright multicolored cloud tops. This material is now caught in the weak winds of Jupiter's upper atmosphere and will likely be dispersed in a band around the planet.
