Sister of Earth: planet Kepler-186 f
Kepler-186 f is the first exoplanet with a radius close to Earth's (about 7200 km) discovered in the habitable zone of its parent star.
So far no one knows if Kepler-186 f is inhabited.
Yeah, Venus and Mars are also in the habitable zone of the solar system, but no one has found any traces of life there yet.

Preserved impact crater in Australia🏜
Wolfe Creek was formed by the fall of an iron meteorite weighing about 5,000 tons (!) about 300,000 years ago.
The crater is 880 meters in diameter and almost 60 meters deep.
📌For illustration: 500,000 years ago, humans became modern, and 160,000 years ago the Cro-Magnon appeared.

This photo depicts not a cosmonaut, but l the RadioScape-1 satellite
It was created on the basis of Orlan-M spacesuit hull. Inside the empty space suit there were three batteries, a radio transmitter and internal sensors for measuring temperature and battery charge.
Unfortunately, the RadioScape-1 mission was not a success. It ceased working after two turns around the Earth due to battery failure.

Emerging star
Hubble has detected a new star, Earendel, Morning Star (WHL0137-LS), which is the farthest star on record from Earth. (WHL0137-LS).
The astronomical object is 12.9 billion light years away!

India divided into 4 groups.
Each group having almost equal gdp)
Apparently GDP of Northern Part of India (9 states 3 union territories including new delhi) is equal to just two states in west (Gujarat and Maharashtra) includes major cities like Mumbai, Pune, Nagpur Ahemdabad, Surat etc. And 3 states in south
Here wealth is equally distributed this region also have higher litracy rate and per capita GDP.

An impressive natural phenomenon - the halo effect.

The Lyrids are an annually active meteor shower formed by comet C/1861 G1 Thatcher
Historical records show that mankind has been observing the Lyrids for over 2,500 years.
✔️The oldest mention of it comes from China: it says that "the stars fell like rain" on the night of March 16, 687 B.C.
Earlier it was much more active than it is now. On April 20, 1803, a meteor storm blew over the east coast of the United States - the number of shooting stars was as high as 700 per hour!

Why is Pluto no longer considered a planet?
Since 2006, Pluto was classified as "minor planets and asteroids”.
Scientists were forced to revise the classification by the discovery of Ceres and Eris. They, like Pluto, have not yet cleared their orbit of extraneous celestial bodies. In addition, Pluto cannot be considered the most massive body in its neighborhood.
Therefore, despite the presence of an atmosphere and its own satellite, it is still not considered the ninth planet.

Magnetar Artistic Concept
On December 27, 2004, a gamma ray burst from SGR 1806-20 arrived in the solar system. The burst was so powerful that it impacted Earth's atmosphere more than 50,000 light-years away.
The magnetar emitted more energy in one tenth of a second than the Sun emits in 100,000 years. The outburst is considered the largest explosion in the galaxy since the supernova SN 1604, observed by Johannes Kepler in 1604.

On April 9, a huge prominence was observed over the southern hemisphere of the Sun, with a total length of about 1 million km!
There is no data yet on how many hours it lasted.
The animation above is made for you from the latest images from the solar space observatory. Enjoy with us.

The universe's most powerful magnets
There are objects in the universe with extremely powerful magnetic fields. Even within a radius of 1000 kilometers around it, life would be impossible due to distortions of electron clouds of atoms under the influence of its magnetic field.
This object is a magnetar - a neutron star, the first evidence of whose existence was obtained in 1998 by observing a powerful flash of gamma-ray and X-ray radiation. Today scientists know of 30 magnetars.
The diameter of such a star is about 20 km and its mass is about 1.4 solar masses. They are formed from massive stars with a mass 10-25 times the mass of the Sun.
The density of the inside of a magnetar is such that a tablespoon of its matter weighs more than 100 million tons.😱
