Dark Dwarfs: New Star-Like Objects May Reveal Nature of Dark Matter

Scientists have proposed a new class of stellar objects called “dark dwarfs,” sub-stellar bodies that may glow faintly from the energy released by annihilating dark matter particles. Found near the galaxy’s core, these objects could hold crucial clues about the elusive nature of dark matter. Powered not by fusion but by WIMP-like particles, dark dwarfs would retain lithium-7 in their atmospheres—providing a unique observational marker. Researchers believe telescopes like JWST may soon detect them, offering new evidence in the decades-long hunt for dark matter’s true identity.

NASA Astronaut Captures Rare Red Sprite Over Storm from Space Station

In a rare celestial event, NASA astronaut Nichole “Vapor” Ayers captured a vivid red sprite lightning phenomenon from the International Space Station as it flared above a thunderstorm across Mexico and the southern U.S. The image highlights the importance of orbital observation and NASA's citizen-science initiative, Spritacular, which collects public photos of Transient Luminous Events (TLEs). With only milliseconds to appear, these upper-atmosphere flashes remain one of Earth’s most mysterious natural occurrences, offering a glimpse into powerful storm dynamics and possible links to lightning on other planets.
