NASA Telescopes Tune Into a Black Hole Prelude, Fugue

NASA has released three new sonifications that explore different stages of black hole evolution. These include WR 124, a massive star potentially collapsing into a black hole; SS 433, a binary system emitting X-rays; and Centaurus A, a galaxy with a supermassive black hole launching a jet across its span.

NASA's Hubble Pinpoints Roaming Massive Black Hole

Researchers have discovered a rare, wandering supermassive black hole devouring a star in a galaxy 600 million light-years away. Unlike typical tidal disruption events that occur at galactic centers, this event was observed 2,600 light-years from the galaxy's core, indicating the presence of a second, offset black hole.

Webb Maps Full Picture of How Phoenix Galaxy Cluster Forms

Researchers have resolved the mystery of the Phoenix Galaxy Cluster's high star formation rate by utilizing data from the James Webb Space Telescope and other observatories. They discovered that intermediary warm gas within cavities tracing the very hot gas reconciles the cooling and star-formation rates.

This Quasar May Have Helped Turn the Lights on for the Universe

The newly discovered quasar J1429+5447 in the early universe, with its rapid X-ray brightening, reveals a powerful jet pointed toward Earth. This rare finding provides key insights into reionization and the mysterious growth of supermassive black holes.

NASA’s Swift Studies Gas-Churning Monster Black Holes

Swift Observatory has discovered two supermassive black holes disrupting a gas cloud at the center of a distant galaxy, producing periodic flares as they orbit each other. The event is identified as the tidal disruption of a massive gas cloud, offering new insights into black hole interactions and galaxy evolution.

Celebrate NASA’s Chandra 25th Anniversary

NASA’s Chandra X-ray Observatory marks 25 years in space with the release of 25 stunning new images, showcasing its unparalleled view of the universe. From black holes to exploding stars, Chandra continues to revolutionize our understanding of the cosmos.
