[SAPOD]Introducing today’s space imagery. We have picked up characteristic images introduced by sorae in the past and attractive images released by space agencies around the world. (There is a link to the original article at the end of the article)

- sorae – Galaxies that periodically brighten, the result of stars being torn apart by black holes?
This is a drawing of “a star that is partly torn apart as it approaches a supermassive black hole” introduced by sorae in an article dated January 23, 2021.imaginationis.
This image was used to explain the brightening phenomenon occurring in the active galaxy ESO 253-3, which is about 570 million light-years away, announced by a research group at the University of Hawaii at Manoa.
This brightening phenomenon appears to be at the center of ESO 253-3Supermassive black hole (approximately 78 million times the mass of the Sun)It is believed that the brightening phenomenon is occurring repeatedly because the fixed star orbiting the 114-day period “survives while being torn apart every time it approaches the black hole”.

In addition, it is estimated that the star loses gas equivalent to about three times the mass of Jupiter every time it approaches the black hole.

Glossary
【active galaxy】
Some galaxies radiate strong electromagnetic waves from a very narrow central region. Such galaxies are called active galaxies. The central region is called “active galactic nucleus” or “active galactic nucleus” (AGN).
