🔆Manganese:

✅Manganese is the fifth-most abundant metal on earth that exists in the form of oxides, carbonates and silicates. 
✅It is present in water, soil and rock as a naturally occurring component.
Properties
✅It is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel.
✅Its minerals are widely distributed, with pyrolusite (manganese dioxide) and rhodochrosite (manganese carbonate) being the most common.
✅It somewhat resembles iron in general chemical activity.
✅It oxidizes superficially in air and rusts in moist air. 
✅It is obtained by reducing the oxide with sodium, magnesium or aluminium, or by the electrolysis of manganese sulfate.
✅Its ores are primarily found in Australia, South Africa, China, Gabon and Brazil.
✅It is essential for the growth of plants and is also involved in the assimilation of nitrates in plants and algae.

Gaia BH3 - Massive Black Hole:

✍️ Astronomers have discovered a massive Black Hole in our Galaxy, named “Gaia BH3”.
✍️ It’s the 2nd-closest known Black hole to Earth. It is 33 times heavier than the sun and the most massive black hole of stellar origin in the Milky Way, surpassing Cygnus X-1.
✍️ Stellar black holes are formed as a result of the collapse of a single star.
✍️ Black holes are extraordinarily dense objects with gravity so strong that not even light can escape, making it difficult to spot them.
✍️ They are formed when a massive star collapses in on itself at the end of its life, creating an incredibly dense object with a gravitational pull that is so strong that it warps space-time around it.
✍️ Supermassive Black Hole masses ranging from millions to billions of times that of the sun, found at the centres of most galaxies including our own Milky Way galaxy.
