RHESSI Spots an Unexpected X-ray Flare In a Quiet Region of the Sun

06.03.2015
On Sept. 29, 2013, a giant filament on the sun, stretching some 200,000 miles long across the northwest quadrant of the sun, erupted in a spectacular fashion, earning the nickname "Canyon of Fire."

Heliophysicist Dr. Roger J. Thomas passes away

05.27.2015
Dr. Roger J. Thomas was a scientist of immense integrity, focus, and commitment. In over 40 years at Goddard, he provided the optical design or advised on essentially every solar extreme ultraviolet spectrograph flown by NASA or ESA and was widely recognized for his contributions to their record of success. He was a linchpin of the SERTS and EUNIS sounding rocket investigations over a span of 30 years and 13 flights. He was also over the years a Principal Investigator, Co-Investigator, Project Scientist for the renowned OSO satellites, Study Scientist, Deputy Chief of NASA's Solar and Heliospheric Physics Office, and author or co-author of over 200 scientific publications. He will be deeply missed by his many friends and colleagues at Goddard and in the worldwide scientific community.

Overview

The Heliophysics Science Division conducts research on the Sun, its extended solar-system environment (the heliosphere), and interactions of Earth, other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace -- Earth's uppermost atmosphere, the ionosphere, and the magnetosphere -- and the changing environmental conditions throughout the coupled heliosphere (solar system weather).

Scientists in the Heliophysics Science Division develop models, spacecraft missions and instruments, and systems to manage and disseminate heliophysical data. They interpret and evaluate data gathered from instruments, draw comparisons with computer simulations and theoretical models, and publish the results. The Division also conducts education and public outreach programs to communicate the excitement and social value of NASA heliophysics.
