... Adirondack Rock on Mars . ... Still, its relatively large size and dust-free surface made it the first destination for the robotic Spirit rover currently roving Mars. ... On January 2, the robot spacecraft STARDUST became one of the first to plow through the surrounding cloud of dust and grit to photograph the very heart of a comet. ... Make your background the closest image of Mars yet. The Spirit Rover currently rolling on Mars has taken the highest resolution image to date of another planet. ...

Educator's Guide to Impact Craters . ... Just about all craters have deep central depressions, raised rims, and a blanket of ejected material surrounding them. ... Look for classical cratering features: basin, raised rim, ejecta blanket (material excavated from the crater and dumped around it, visible as white flour on the colored powder), and rays (material shot out at high velocity forming lines pointing directly away from the impact site). ... The material lies like a blanket around the crater. ...

This video fades back and forth between views of the stellar nursery Monoceros R2 in visible and infrared light. The visible-light view was created from digitised photographs through red and blue filters forming part of the Digitized Sky Survey 2 (DSS) and the new infrared view comes from the VISTA telescope at Paranal. ...

... 2009 August 3 . T Tauri: A Star is Formed . ... Explanation: What does a star look like when it is forming? The prototypical example is the variable star T Tauri , visible as the bright orange star near the image center. The orange star centered in this remarkable telescopic skyview is T Tauri, prototype of the class of T Tauri variable stars. ... To further complicate the picture, infrared observations indicate that T Tauri itself is part of a multiple star system. ... About APOD | ...

... We report on our ongoing project ``Infrared Study of HII Regions Associated with Small Clouds.' ... These IR data, combined with optical imaging (which will be obtained from the IAC-80 telescope), IRAS survey maps, and existing CO observations of the associated clouds, will allow us to undertake a detailed investigation of the gas-to-dust mass ratio, initial mass function and the star-formation efficiency in these complexes. ...

... High-resolution Near-infrared Study of the Deeply Embedded Young Stellar Object S140 IRS 3 . ... P22P We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3 within the L1204 molecular cloud. ... The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a. Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. ...

The satellites are covered by nearly 1000 small, front-surface aluminum mirrors that are machined by technology students in Utah and polished by tens of thousands of students all over the world. ... And this is only small story about it. ... We will be able to measure the angular position of that satellite by observing sunlight flashes from small mirrors mounted on the surface of the satellite, as it passes across the starry sky before sunrise and after sunset.. ...
