﻿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2024 June 16 IFRAME: [2]https://www.youtube.com/embed/ubBzcSD8G8k?rel=0 Animation: Black Hole Destroys Star Video Illustration Credit: [3]DESY, [4]Science Communication Lab Explanation: What happens if a star gets too close to a black hole? The [5]black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the [6]difference in gravitational pull across the star that creates the destruction. In the [7]featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the [8]star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an [9]accretion disk. The [10]animation then takes you into the accretion disk while looking toward the black hole. Including the [11]strange visual effects of [12]gravitational lensing, you can even [13]see the far side of the disk. Finally, you [14]look along one of the [15]jets being expelled along the spin axis. Theoretical [16]models indicate that these jets not only expel energetic gas, but also create energetic [17]neutrinos -- one of which may have been [18]seen recently on [19]Earth.
