A breakthrough in Hilbert’s sixth problem is a major step in grounding physics in math

We've long known that black holes can produce powerful jets of ionized gas. These jets stream away from the black hole at nearly the speed of light. Jets produced by supermassive black holes are so powerful they are seen as quasars from billions of light-years away. But when you think about it, jets are a bit counterintuitive. Black holes trap and consume material through their tremendous gravity, so how can they push streams of material away? A recent study in Publications of the Astronomical Society of Japan shows how it works.

Katy Perry just flew to suborbital space on a historic all-female flight with Blue Origin. The trip, though brief, changed her in significant ways the pop star said.

This new image showcases the dazzling young star cluster NGC 346. Although both the James Webb Space Telescope and the Hubble Space Telescope have released images of NGC 346 previously, this image includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.
