The Sun is revealing itself in dramatic detail and shedding light on how other stars may form and behave throughout the universe – all thanks to NASA’s Parker Solar Probe. […]
Since NASA’s Parker Solar Probe launched on Aug. 12, 2018, Earth has made a single trip around the Sun — while the daring solar explorer is well into its third orbit around our star. With two close passes by the Sun already under its belt, Parker Solar Probe is speeding toward another close solar approach on Sept. 1, 2019. […]
We can’t put the whole Milky Way on a scale, but astronomers have been able to come up with one of the most accurate measurements yet of our galaxy’s mass, using NASA’s Hubble Space Telescope and the European Space Agency’s Gaia satellite. […]
A little over 4 billion years ago, the planets in our solar system coexisted with vast numbers of small rocky or icy objects orbiting the Sun. […]
NASA’s historic Parker Solar Probe mission will revolutionize our understanding of the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds. […]
A dramatic magnetic power struggle at the Sun’s surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights the role of the Sun’s magnetic landscape, or topology, in the development of solar eruptions that can trigger space weather events around Earth. […]
Solar material repeatedly bursts from the sun in this close-up captured on July 9-10, 2016, by NASA’s Solar Dynamics Observatory, or SDO. […]
The sun emitted a mid-level solar flare, peaking at 8:29 pm EDT on April 17, 2016. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. […]
The sun emitted a mid-level solar flare, an M7.9-class, peaking at 4:16 a.m. EDT on June 25, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. […]
NASA’s Wide-field Infrared Survey Explorer discovers pair of brown dwarf stars that are the closest to the sun found since 1916. […]
