Title The Seven Sisters Pose for Spitzer
Description The Seven Sisters, also known as the Pleiades star cluster, seem to float on a bed of feathers in a new infrared image from NASA's Spitzer Space Telescope. Clouds of dust sweep around the stars, swaddling them in a cushiony veil. The Pleiades, located more than 400 light-years away in the Taurus constellation, are the subject of many legends and writings. Greek mythology holds that the flock of stars was transformed into celestial doves by Zeus to save them from a pursuant Orion. The 19th-century poet Alfred Lord Tennyson described them as "glittering like a swarm of fireflies tangled in a silver braid." The star cluster was born when dinosaurs still roamed the Earth, about 100 million years ago. It is significantly younger than our 5-billion-year-old sun. The brightest members of the cluster, also the highest-mass stars, are known in Greek mythology as two parents, Atlas and Pleione, and their seven daughters, Alcyone, Electra, Maia, Merope, Taygeta, Celaeno and Asterope. There are thousands of additional lower-mass members, including many stars like our sun. Some scientists believe that our sun grew up in a crowded region like the Pleiades, before migrating to its present, more isolated home. The new infrared image from Spitzer highlights the "tangled silver braid" mentioned in the poem by Tennyson. This spider-web-like network of filaments, colored yellow, green and red in this view, is made up of dust associated with the cloud through which the cluster is traveling. The densest portion of the cloud appears in yellow and red, and the more diffuse outskirts are shown in green hues. One of the parent stars, Atlas, can be seen at the bottom, while six of the sisters are visible at top. Additional stars in the cluster are sprinkled throughout the picture in blue. The Spitzer data also reveal never-before-seen brown dwarfs, or "failed stars," and disks of planetary debris (not pictured). John Stauffer of NASA's Spitzer Space Telescope mission says Spitzer's infrared vision allows astronomers to better study the cooler, lower-mass stars in the region, which are much fainter when viewed in optical light. Stauffer, who admits to being biased because the Pleiades is his favorite astronomical object, says the cluster is the perfect laboratory for understanding the evolution of stars. This image is made up of data taken by Spitzer's multiband imaging photometer and its infrared array camera. Light with a wavelength of 4.5 microns is blue, light of 8 microns is green, and light of 24 microns is red.

title Mars Reconnaissance Orbiter Adjusts Angle of Orbit
Description This artist's concept of NASA's Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet. The large silver circular feature above the spacecraft bus is the high-gain antenna, the spacecraft's main means of communicating with Earth. The long, thin pole behind the bus is the antenna for the Shallow Subsurface Radar instrument (SHARAD). Seeking liquid or frozen water, this instrument will probe the subsurface using radar waves at frequencies of 15 to 25 megahertz, "seeing" in the first few hundred feet (up to 1 kilometer) of Mars' crust. The large instrument covered in black thermal blanketing in the center is the High Resolution Imaging Science Experiment camera (HiRISE). It will provide the highest-resolution images ever taken from Mars orbit. The Electra telecommunications package is the gold-colored instrument directly left of the high-resolution camera. It will act as a communications relay and navigation aid for Mars spacecraft. To the right of the high-resolution camera is the Context Imager (CTX). Credit: NASA/JPL

Description This artist's concept of the Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet. The large silver circular feature above the spacecraft bus is the high-gain antenna, the spacecraft's main means of communicating with both Earth and other spacecraft. The long, thin pole behind the bus is the SHARAD antenna. Seeking liquid or frozen water, SHARAD will probe the subsurface using radar waves at a 15-25 MHz frequency band, "seeing" in the first few hundreds of feet (up to 1 kilometer) of Mars' crust. The large instrument (covered in black thermal blanketing) in the center is the HiRISE camera. This powerful camera will provide the highest-resolution images from orbit to date. The other easily visible instruments are: the Electra telecommunications package which is the gold-colored instrument directly left of the HiRISE camera. It will act as a communications relay and navigation aid for Mars spacecraft. To the right of the HiRISE camera is the Context Imager (CTX).

Venus and Pleiades Mingle in the Sky The sky chart in figure 1, illustrates the Venus-Pleiades encounter that reached its closest approach on April 11, 2007. The Pleiades are a tight gem-like cluster of stars that resemble a tiny dipper (but should not be confused with the Little Dipper constellation). If you look west shortly after sunset, Venus will be the brightest object in the sky. If the skies are clear and dark, you'll also see the Pleiades twinkling above Venus. On April 19, the moon will join the party, sliding between Venus and the Pleiades. Viewers in the northern and southern hemispheres will be able to witness the event.
