J0030…

Topics: Astronomy, Astrophysics, NASA, Neutron Stars, Pulsars NASA’s NICER instrument reveals that neutron stars are not as simple as we thought. Pulsars are the lighthouses of the universe. These tiny, compact objects are neutron stars — the remnants of once-massive stars — that spin rapidly, beaming radiation into space. Now, for the first time, astronomersContinue reading “J0030…”

Yonder Water Worlds…

Topics: Astrobiology, Astronomy, Astrophysics, Exoplanets, Space Exploration Hot, ocean-covered exoplanets with hydrogen-rich atmospheres could harbor life and may be more common than planets that are Earth-like in size, temperature, and atmospheric composition. According to astronomers at the University of Cambridge, UK, this newly defined class of exoplanets could boost the search for life elsewhere inContinue reading “Yonder Water Worlds…”

Ganymede…

Topics: Astronomy, Astrophysics, NASA, Planetary Science, Space Exploration Ganymede, get ready for your close-up. No probe has gotten a good view of Jupiter’s largest moon since 2000, when NASA’s Galileo spacecraft swung past the strange world, which is the largest moon in the whole solar system. But on Monday (June 7),  at 1:35 p.m. EDT (1735 GMT),Continue reading “Ganymede…”

Sun Quake…

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…”

The Question is Moot…

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…”

Nabta Playa…

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…”
