✨Black holes absorb dark matter, and over the billions of years since galaxies were first formed, this absorption of dark matter in black holes has very likely altered the population of galaxies from what we can observe today✨

✨On July 24, 1969, the Apollo 11 crew with Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Buzz Aldrin splashed down in the Pacific Ocean after achieving the first lunar landing.
Upon splashing down, the Apollo 11 crew underwent a 21-day quarantine. The purpose of this was to protect against the small possibility of lunar contagion. This procedure was discontinued after Apollo 14. This photo provides a candid view of the astronauts in the Mobile Quarantine Facility✨

✨Antares Star✨
✦Antares is a bright red supergiant star in the constellation of Scorpio.
Antares is 550 light years from Earth and the brightest star in the constellation of Scorpius.
Antares takes its name because of its distinctly red color, which compares to that of Mars. The Greek name Antares means "Rival of Mars", the god of war.
The Romans called the star Cor Scorpionis, meaning Heart of the Scorpion. However, they had been anticipated in this by the Assyrians, Babylonians, and Sumerians, who for at least two millennia had also known the star as the Heart of the Scorpion.
According to ancient Arab tradition, Antares is the warrior-poet Antar's star.
Many of the old Egyptian temples are oriented so that the light of Antares plays a role in the ceremonies performed there.
Antares was also known as Satevis in ancient Persia and was one of the four "royal stars" of the Persians around 3000 BC. It was also known as Jyeshtha in ancient India✨
