    Heliophysics Presentation at NASM 2011

    May 10th, 2012
    (updated Dec. 3rd, 2015)

    The Maryland Space Business Roundtable sponsored their 12th annual event at the National Air and Space Museum the evening of September 14, 2011. The event is held in support of the roundtable's programs in education for students in science, technology, engineering and math. This year's event, Earth and Space: A Journey of Wonder & Discovery, with remarks from Goddard Center Director Rob Strain and NASA Administrator Charlie Bolden, included a program featuring a 5-panel member of scientists: Dr. Waleed Abdalati, NASA Chief Scientist; Dr. Arthur Hou, GPM Mission Scientist; Dr. Jim Garvin, Chief Scientist, NASA Goddard; Dr. Holly Gilbert, Goddard Solar Physics Laboratory Chief; and Dr. Amber Straughn, Research Astrophysicist. Miles O'Brien, space and science broadcast news veteran moderated the panel. ||

    NASA Spacecraft Uncover Mystery Behind Auroral Beads

    Aug. 14th, 2020
    (updated May 3rd, 2023)

    A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space. Known as auroral beads, these lights often show up just before large auroral displays, which are caused by electrical storms in space called substorms. Until now, scientists weren’t sure if auroral beads are somehow connected to other auroral displays as a phenomenon in space that precedes substorms, or if they are caused by disturbances closer to Earth’s atmosphere.But powerful new computer models, combined with observations from NASA’s Time History of Events and Macroscale Interactions during Substorms – THEMIS – mission, have provided the first direct evidence of the events in space that lead to the appearance of these beads, and demonstrated the important role they play in our local space environment. ||

    NASA Spacecraft Finds New Magnetic Process in Turbulent Space

    May 9th, 2018
    (updated May 3rd, 2023)

    Though close to home, the space immediately around Earth is full of hidden secrets and invisible processes. In a new discovery reported in the journal Nature, scientists working with NASA’s Magnetospheric Multiscale spacecraft — MMS — have uncovered a new type of magnetic event in our near-Earth environment by using an innovative technique to squeeze extra information out of the data.Magnetic reconnection is one of the most important processes in the space — filled with charged particles known as plasma — around Earth. This fundamental process dissipates magnetic energy and propels charged particles, both of which contribute to a dynamic space weather system that scientists want to better understand, and even someday predict, as we do terrestrial weather. Reconnection occurs when crossed magnetic field lines snap, explosively flinging away nearby particles at high speeds. The new discovery found reconnection where it has never been seen before — in turbulent plasma. ||
