This episode discusses the recent discovery of FRB 20250316A, one of the brightest fast radio bursts ever detected. Using the CHIME Outriggers array, researchers pinpointed its location in the galaxy NGC 4141. Subsequent observations with the James Webb Space Telescope revealed a faint infrared source near its origin, which could be a red giant or a massive star.While these stars aren't the direct source, their presence suggests the burst might be caused by a nearby companion neutron star

Gisnt Binary Stars Locked in Rapid Orbit:Astronomers are studying a massive, binary star system called NGC 3603-A1, located in a dense, star-forming region. One star is 93 times the sun's mass and the other is 70 times, making them one of the heaviest pairs known. They orbit each other in just 3.8 days, and their intense interaction causes them to change, with evidence showing the smaller star has stolen material from the larger one. The discovery was sparked by an undergraduate student's

Scientists propose that "dark dwarfs"—brown dwarfs powered by dark matter—could reveal what dark matter is made of. Meanwhile, LIGO and its partners detected the most massive black hole merger ever seen, offering new insights into black hole formation. At the same time, new simulations suggest there may be many hidden, faint galaxies orbiting the Milky Way, helping to solve a mystery in our understanding of dark matter and galaxy formation.

NASA's new SPHEREx telescope is mapping the entire sky in infrared, helping scientists study the origins of stars, planets, and life—and the data is shared publicly. Researchers also propose a new type of glowing object called a "dark dwarf," powered by dark matter, which could offer clues about what dark matter is. Meanwhile, a giant object named 3I/ATLAS, recently spotted speeding through our solar system, is confirmed to be interstellar and may reveal how planets form in other star systems.
