For #BlackHoleFriday, we're defining "accretion" in a special Goddard Glossary, looking specifically at the role it plays in finding and studying black holes.

Video Description:
:00 A woman with brown and purple hair in a gray shirt talking and gesturing in front of an illustration of a black hole accretion disk. The disk is a spiral of yellows and oranges with a bright jet of yellow and white emanating from its center. The word accretion is spelled out syllabically in white above the woman’s head.
:04 Flying over a river delta, with bright green vegetation broken up by several small blue streams of water.
:09 Fade back to the woman talking.
:16 Slow push in on an image of a black hole, which looks like a fuzzy glowing orange donut with the lower half glowing a brighter yellow, all against a black background. White text in the top right reads "Credit: EHT."
:19 Back to the woman talking.
:21 A dark sky glowing faintly brown, speckled with stars. In the lower third, a black hole in space is distorting the stars surrounding it. A bright yellow star is pulled in toward the black hole from the upper left. As it approaches the black hole, it stretches out into a long, ropy beam of light, which orbits around the black hole in a donut shape, expelling puffs of bright yellow light.
:31 Back to the woman talking.
:36 An animation of a black hole with an accretion disk on a black background. The accretion disk is bright orange material flowing in concentric rings. The far side of the disk appears bent up over the black hole, giving the whole object a shape like an eye.
:41 The black hole tips toward the viewer. From the top down, it just looks like a spinning disk of orange and red rings circling the invisible black hole.
:51 Fade back to the woman talking in front of the accretion disk.
