The dimming of Betelgeuse could be caused by a black hole
When the Betelgeuse star began to fade rapidly in 2019, many thought that it would soon flare up as a supernova. However, over time, its luminosity recovered, and scientists began to think about the cause of this phenomenon. Now there is a theory that it was caused by a black hole that passed near the…

Spiral Galaxy ESO 137-001
Here is an atypical spiral galaxy with a jumper (an elongated structure of stars and gas in the galactic disk), which looks like a dandelion seed head caught up by the wind. In addition, ESO 137-001 behaves accordingly, spreading its “seeds” in space.⠀The galaxy is moving at a speed of about seven million kilometers per…
