"The Mikulski Archive for Space Telescopes (MAST) is a NASA funded project to support and provide to the astronomical community a variety of astronomical data archives, with the primary focus on scientifically related data sets in the optical, ultraviolet, and near-infrared parts of the spectrum. MAST is located at the Space Telescope Science Institute (STScI)."

The Sustainability Solution states: the absence of ETI observation can be explained by the possibility that exponential or other faster-growth is not a sustainable development pattern for intelligent civilizations.

February 20, 2009: The first gamma-ray burst to be seen in high-resolution from NASA's Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest motions and the highest-energy initial emissions ever seen.

The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 6.9 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through highly customizable query forms, and full-text scans of much of the astronomical literature which can be browsed or searched via our full-text search interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 7.6 million records maintained by our collaborators.

In the wake of Shepard Fairey's debacle with the AP over the rights to the image he used as reference/inspiration for his wildy popular Obama poster, I wanted to share a list of Public Domain Licensed images, in this case, astronomy. Fairey's situation should hit home with all pixel junkies out there and remind us that we have to pay close attention to the licenses associated with the images we use in our design work. I've compiled a list of beautiful, inspiring astronomy images that all have a Public Domain License.

We review properties of theories for the variation of the gravitation and fine structure 'constants'. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that are consistent with time-variation in the fine structure 'constant' since a redshift of 3.5. The behaviour of a simple class of varying-alpha cosmologies is outlined in the light of all the observational constraints.

The CDS Service for astronomical Catalogues

The Tau Zero Foundation is a volunteer group of scientists, engineers, entrepreneurs, and writers who have agreed to work together toward practical interstellar flight and to use this quest to teach you about science, technology, and our place in the universe. By posting the latest developments and unfinished advancements here, we give students the starting materials to begin their own discoveries. By showing both how daunting and incredible this challenge is, we hope to increase attention on protecting the habitability of Earth while planning journeys into the galaxy. By reaching for the stars we will create benefits every step of the way.

Society for Planetary SETI Research (SPSR) is an organization of scientists and scholars from a variety of disciplines formed around their common interest in anomalies on planets and their satellites whose origins may be the result of intelligent activity. The focus of SPSR research is primarily the surfaces of Mars and the Moon as revealed by orbiter and lander investigation.

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.It is being used in planetarium projectors. Just set your coordinates and go.

As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. Even if it does exist, dark matter would be unable to reconcile all the current discrepancies between actual measurements and predictions based on theoretical models. Hence the number of physicists questioning the existence of dark matter has been increasing for some time now.

Stuart Clark tells for the first time the full story behind Carrington's observations of a mysterious explosion on the surface of the Sun and how his brilliant insight-that the Sun's magnetism directly influences the Earth-helped to usher in the modern era of astronomy.

It's a cute graphic, but not much more than that. You move the cursor and the simulated night sky moves in response - and it's a great example of how the Internet can take us in the wrong direction. Do you remember kids getting books and ... gasp ... going outdoors at night, looking upward and finding those constellations, instead of searching for them on an animation?
