Press Releases & Feature Stories
- NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles.
- NASA’s MAVEN spacecraft captured an ultraviolet image of hydrogen surrounding comet Siding Spring. The cloud was about a half degree across, comparable in size to Earth’s moon as seen from Earth.

- A gigantic sunspot – almost 80,000 miles across --can be seen on the lower center of the sun in this image from NASA’s Solar Dynamic Observatory captured on Oct. 23, 2014.
NASA Solar Physicist Dr. Brian Dennis presented a Maniac Talk entitled "From Picking Potatoes to Measuring the Biggest Bangs in the Solar System -- Always a Farm Boy!" Brian described his formative years in England, then summarized our present understanding of how solar flares work and reviewed possible advances in instrumentation that could lead to major breakthroughs in the future.

NASA climate scientist Dr. P.K. Bhartia presented a Maniac Talk entitled "Maxwell Demon, Black Swan and a Romp in Scientific Hinterlands." PK discussed his roller coaster career, which got nearly derailed after a brief tryst with history and his obsession for understanding esoteric details of measurements that once in a while leads to something interesting.

Bruce Woodgate Passes
Dr. Bruce Woodgate passed away April 28, 2014 after suffering several strokes. Bruce has a remarkable career, spanning nearly 40 years as a civil servant at Goddard. Bruce was also a mentor to legions of students and young scientists. He retired recently and was still working on UV detectors as an Emeritus scientist. He had very broad interests, in subjects ranging from earth science to stellar atmospheres to exoplanets to large scale structure in the universe. Bruce was probably best known as the PI for the Space Telescope Imaging
Spectrograph (STIS) for the Hubble Space Telescope. In this capacity he led
the design and development of the instrument, including preparation of
flight-worthy large-format CCDs and Multi Anode Multi Array (MAMA) detectors
that dramatically advanced the state of the art over the previous HST
- The greens and blues of the ocean color from NASA satellite data have provided new insights into how climate and ecosystem processes affect the growth cycles of phytoplankton.
- Iceland's Holuhraun lava field offers spectacular views from the ground and from low-flying aircraft, and infrared imaging makes the view from space spectacular, too.
