In this episode of
SpaceTime, we uncover the mysteries lurking in the cosmos, from a rogue supermassive black hole to a meteorite crash in Georgia, and the origins of asteroids Bennu and Ryugu.
An Invisible Monster in the CosmosAstronomers have made a chilling discovery of a supermassive black hole, 600 million light years away, that has been lurking in the darkness of space. Using NASA's Hubble and Chandra space telescopes, along with a Very Large Array radio telescope, researchers identified this rogue black hole that consumes stars and planets that venture too close. The black hole was revealed through a tidal disruption event, where a star was torn apart and swallowed, offering a glimpse into the physics of these cosmic behemoths.
Meteorite Slams into Georgia HomeIn an extraordinary event, a meteorite crashed through a house in Atlanta, Georgia, on June 26, narrowly missing the homeowner. Witnessed by hundreds, the fireball streaked across the sky before fragments penetrated the roof and ceiling. Planetary geologist Scott Harris retrieved samples for analysis, revealing the meteorite's origins in the asteroid belt, dating back 4.56 billion years, and potentially linked to the breakup of a larger asteroid.
Origins of Asteroids Bennu and RyuguRecent research suggests that both Bennu and Ryugu may share a common ancestry, originating from the same collisional family of asteroids known as Polana. Spectral data comparisons indicate similarities between these asteroids, supporting the hypothesis that they were formed from the remnants of a larger body that fragmented early in the solar system's history. This discovery opens new avenues for understanding the evolution of these near-Earth asteroids.
