Eclipse 2017
"On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun. Anyone within the path of totality can see one of nature’s most awe inspiring sights - a total solar eclipse. This path, where the moon will completely cover the sun and the sun's tenuous atmosphere - the corona - can be seen, will stretch from Salem, Oregon to Charleston, South Carolina. Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun's disk. NASA created this website to provide a guide to this amazing event. Here you will find activities, events, broadcasts, and resources from NASA and our partners across the nation."

Center for Astrostatistics
"Astronomy at the beginning of the 21st century, and particularly research arising from wide-field survey observatories at various wavebands, finds itself with serious challenges in statistical treatments of data to achieve its astrophysical goals. A vast range of statistical problems arise in the scientific interpretation of astronomical studies involving sampling, multivariate and survival analysis, image and spatial analysis, signal processing and time series analysis, nonlinear regression, and more. It is this diversity of statistical issues confronting astronomy today that led to the creation of the Center for Astrostatistics at Penn State in 2003 to facilitate development and promulgation of statistical expertise and toolkits for astronomy and related observational sciences. The Center is housed in the Department of Statistics. The activities of the Center are multi-faceted: conduct and support research on forefront problems; provide forums where active astrostatistical researchers can interact; foster new cross-disciplinary collaborations; liaise with other organizations oriented towards statistical applications in physical sciences. One of the aims is to disseminate advanced methodologies to the wider astronomical and space science communities through curriculum development, tutorial workshops, Web-based resources, and public software. The Center serves as a crossroads where researchers at the interfaces between statistics, data analysis, astronomy, space and observational physics collaborate, develop and share methodologies, and together prepare the next generation of researchers.

Picturing the Cosmos — University of Minnesota Press
"Picturing the Cosmos examines the Hubble’s deep space images, highlighting the resemblance they bear to nineteenth-century paintings and photographs of the American West and their invocation of the visual language of the sublime. Strikingly illustrated, this book reveals the scientific, aesthetic, and cultural significance of the Hubble pictures, offering an understanding of how they shape our ideas about the cosmos. "

[1410.2895] Observing Ultra-High Energy Cosmic Rays with Smartphones
"We propose a novel approach for observing cosmic rays at ultra-high energy (>1018~eV) by repurposing the existing network of smartphones as a ground detector array. Extensive air showers generated by cosmic rays produce muons and high-energy photons, which can be detected by the CMOS sensors of smartphone cameras. The small size and low efficiency of each sensor is compensated by the large number of active phones. We show that if user adoption targets are met, such a network will have significant observing power at the highest energies."

Brilliant GRB Blast with an Amateur Twist - News Blog - SkyandTelescope.com
"The gamma-ray burst GRB 130427A erupted on April 27th with record-setting power. That made it an easy target for two of NASA's orbiting observatories, major ground-based telescopes, and even one lucky backyard observer. It reached visual magnitude 7.4."

"Doppler weather radar imaging enabled the rapid recovery of the Sutter’s Mill meteorite after a rare 4-kiloton of TNT–equivalent asteroid impact over the foothills of the Sierra Nevada in northern California. The recovered meteorites survived a record high-speed entry of 28.6 kilometers per second from an orbit close to that of Jupiter-family comets (Tisserand’s parameter = 2.8 ± 0.3). Sutter’s Mill is a regolith breccia composed of CM (Mighei)–type carbonaceous chondrite and highly reduced xenolithic materials. It exhibits considerable diversity of mineralogy, petrography, and isotope and organic chemistry, resulting from a complex formation history of the parent body surface. That diversity is quickly masked by alteration once in the terrestrial environment but will need to be considered when samples returned by missions to C-class asteroids are interpreted."

Does All Science Need to be Preserved? Do We Need to Save Every Last Data Point? « The Scholarly Kitchen
"There are at present few best practices for managing and curating data. Libraries have developed, over the decades, processes and plans for how to curate an information collection and to “de-accession” (i.e., discard) unwanted or unnecessary content. At this stage in the development of an infrastructure for data management, there is no good understanding of how to curate a data collection. This problem is compounded by the fact that we are generating far more data than we have capacity to store or analyze effectively."

NASA gets two military spy telescopes for astronomy - The Washington Post
"The secretive government agency that flies spy satellites has made a stunning gift to NASA: two exquisite telescopes as big and powerful as the Hubble Space Telescope. They’ve never left the ground and are in storage in Rochester, N.Y."

Tom Johnson, 1923–2012 - News Blog - SkyandTelescope.com
Thomas J. Johnson, the creator of the modern Schmidt-Cassegrain telescope and the founder of Celestron, died early this morning (March 13, 2012), according to Celestron president and CEO Joe Lupica. Johnson was 89.

He ranked among the most important figures shaping the last half century of amateur astronomy.

Huge US command-
Pentagon boffinry powerhouse DARPA has announced plans to fit a giant new US military command and control airship - known as "Blue Devil Block 2" - with through-the-air optical links offering bandwidth normally achievable only by fibre cables. This is to be done using newly-applied technology developed in the 1990s for use in astronomical telescopes.
