Topics: Astronomy, Astrophysics, ESA, Heliophysics, NASA For new Sun-watching spacecraft, the first solar eruption is always special. On February 12, 2021, a little more than a year from its launch, the European Space Agency and NASA’s Solar Orbiter caught sight of this coronal mass ejection, or CME. This view is from the mission’s SoloHI instrument —Continue reading “Sun Quake…”

Volume of Chaos…
Topics: Astronomy, Astrophysics, Cosmology Physicists have spent centuries grappling with an inconvenient truth about nature: Faced with three stars on a collision course, astronomers could measure their locations and velocities in nanometers and milliseconds and it wouldn’t be enough to predict the stars’ fates. But the cosmos frequently brings together trios of stars and black holes.Continue reading “Volume of Chaos…”
Antistars…
Topics: Astronomy, Astrophysics, Cosmology, High Energy Physics Fourteen possible antimatter stars (“antistars”) have been flagged up by astronomers searching for the origin of puzzling amounts of antihelium nuclei detected coming from deep space by the Alpha Magnetic Spectrometer (AMS-02) on the International Space Station. Three astronomers at the University of Toulouse – Simon Dupourqué, LuigiContinue reading “Antistars…”

Topics: Astrobiology, Astronomy, Astrophysics, SETI Cultural references: The post title refers to NC A&T Alumni, and Civil Rights icon Reverend Jesse Jackson’s appearance on Saturday Night Live, and the Wow! signal. Personal note: This signal appeared on the same day my granddaughter was born. On April 29, 2019, the Parkes Radio Telescope in Australia beganContinue reading “The Question is Moot…”

Topics: African Studies, Astronomy, Astrophysics, Diversity in Science For thousands of years, ancient societies all around the world erected massive stone circles, aligning them with the sun and stars to mark the seasons. These early calendars foretold the coming of spring, summer, fall and winter, helping civilizations track when to plant and harvest crops. TheyContinue reading “Nabta Playa…”
TNOs…
Topics: Astronomy, Astrophysics, Comets, Space Exploration Invisible structures generated by gravitational interactions in the Solar System have created a “space superhighway” network, astronomers have discovered. These channels enable the fast travel of objects through space and could be harnessed for our own space exploration purposes, as well as the study of comets and asteroids. ByContinue reading “TNOs…”
