Curious Universe: Seasons of the Sun

As Earth makes its annual trip around the Sun, we feel the impacts of its journey in the form of seasons. Our planet’s tilt in relation to the Sun determines what season we experience here on Earth. But, did you know that the Sun goes through seasons too? Delores Knipp, Dean Pesnell and Sabrina Savage explain.

New Evidence Our Neighborhood in Space Is Stuffed With Hydrogen

Data from NASA's New Horizons spacecraft suggests the local interstellar medium contains 40% more hydrogen atoms than prior studies suggested.

NASA’s Solar Dynamics Observatory Catches a Lunar Transit

On Oct. 16, 2020, the Moon photobombed NASA’s Solar Dynamics Observatory’s view of the Sun. This apparent crossing in space, called a lunar transit, lasted about 50 minutes, between 3:05 p.m. and 3:53 p.m. ET.

Two NASA Scientists Honored as APS Fellows

Two scientists from NASA's Goddard Space Flight Center in Greenbelt, Maryland, have been named Fellows of the American Physical Society (APS). Li-Jen Chen and Rita M. Sambruna are the honorees for 2020.
