Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abund...
Astronomers have used, for the first time, a novel method to determine the mass of a nearby dead star. The star is a "white dwarf," the shrunken corpse of a star like our sun after it has burned up it...
The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a concept for an 8-meter to 16-meter UVOIR space observatory for launch in the 2025-2030 era. ATLAST will allow astronomers to answer...
We present Wide Field Camera 3 images taken with the Hubble Space Telescope within a single field in the southern grand design star-forming galaxy M83. Based on their size, morphology, and photometry ...
The newly installed Wide Field Camera 3 (WFC3) on the Hubble Space Telescope has been used to obtain multi-band images of the nearby spiral galaxy M83. These new observations are the deepest and highe...
Using the National Science Foundation’s Robert C. Byrd Green Bank Telescope (GBT), astronomer D.J. Pisano from West Virginia University has discovered what could be a never-before-seen river of hydrog...
We report Hubble Space Telescope observations of 6 gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed images in 6 filters from 8140\AA\ to 2200\A...
Space reddenings are derived for 15 Galactic Cepheids from dereddening CCD BVRIc data for AF-type stars in the immediate vicinities of the variables, in conjunction with 2MASS reddenings for BAF-type ...
Spectroscopy of stellar Jets, outflows, and Young stellar objects with the infrared space observatory。
20 April 2007,NASA and the British National Space Centre (BNSC) have signed a historic agreement to jointly study how the two space agencies might work together on future planetary explorations to the...
