Only one side of the moon is visible from Earth, i.e. 50% of the surface. But in fact, we can observe 59%, thanks to lunar librations - small swings of the Moon around a common center with the Earth.

Observing the globular clusters orbiting the Andromeda galaxy, astronomers found out that since its formation, it has absorbed several of its large and small satellites. Andromeda is now the largest galaxy closest to the Milky Way and the largest in the Local Group. F the distance from the Sun to it is 2.5 million light-years, but it is reduced by 300 kilometers every second. The Milky Way will collide with Andromeda in about four billion years.
Compared to our Galaxy, Andromeda has a much larger and more complex stellar halo. This indicates that it destroyed a significant number of its neighbors, possibly larger than the Milky Way destroyed.

Black holes absorb objects in different ways. They can slowly pull gas from the shell of a star and gradually destroy it until thermonuclear fusion stops in it. Or the star will come close enough to the event horizon of the black hole, the latter can tear it apart and "swallow" it piece by piece. This phenomenon is called a "tidal disruption event"
This video shows how recently, for the first time, the planet observation satellite TESS] observed how a black hole tears apart a star from beginning to end exactly according to the tidal destruction scenario.
The black hole in this system weighs about six million suns and is located about 375 million light-years away from us. The destroyed star may have been similar in size to the Sun.

Rainbow clouds appear when the Sun occupies a certain position in the sky, and at the same time is hidden behind dense clouds, then a transparent cloud located nearby can turn into a rainbow.
