NASA Watches the Sun Put a Stop to Its Own Eruption

NASA Watches the Sun Put a Stop to Its Own Eruption On Sept. 30, 2014, multiple NASA observatories watched what appeared to be the beginnings of a solar eruption. A filament — a serpentine structure consisting of dense solar material and often associated with solar […]

TRAPPIST-1 is Older Than Our Solar System

TRAPPIST-1 is Older Than Our Solar System If we want to know more about whether life could survive on a planet outside our solar system, it’s important to know the age of its star. Young stars have frequent releases of high-energy radiation called flares that […]

Watch Martian Clouds Scoot, Thanks to NASA’s Curiosity

Watch Martian Clouds Scoot, Thanks to NASA’s Curiosity Wispy, early-season clouds resembling Earth’s ice-crystal cirrus clouds move across the Martian sky in some new image sequences from NASA’s Curiosity Mars rover. These clouds are the most clearly visible so far from Curiosity, which landed five […]

RAVAN CubeSat Measures Earth’s Outgoing Energy

RAVAN CubeSat Measures Earth’s Outgoing Energy An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth’s climate. The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in […]

NASA’s Scientific Balloon Program Reaches New Heights

NASA’s Scientific Balloon Program Reaches New Heights For decades, NASA has released enormous scientific balloons into Earth’s atmosphere, miles above the altitude of commercial flights. The Balloon Program is currently preparing new missions bearing sensitive instruments, including one designed to investigate the birth of our […]

NASA Studies Tethered CubeSat Mission to Study Lunar Swirls

Two Weeks in the Life of a Sunspot

Two Weeks in the Life of a Sunspot On July 5, 2017, NASA’s Solar Dynamics Observatory watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. The satellite continued to track the region as it […]
