The most powerful stratospheric winds were detected at Jupiter's poles 🧐
Astronomers have made the first direct measurements of wind speeds in Jupiter's mid-atmosphere. With the help of the Shoemaker-Levy 9 comet. It spectacularly crashed into the gas giant in 1994, leaving new molecules in its stratosphere after its death, which have been carried in it by the winds ever since.
Astronomers are observing the movements of hydrogen cyanide brought by Comet Shoemaker-Levy 9 and managed to measure the speed of the winds in Jupiter's stratosphere.
The jets detected in this part of Jupiter have an average speed of about 600 km/hour.

Axiom Space to send self-assembling robots to the ISS 🦾
The Ax-1 mission will depart April 8 on the Crew Dragon spacecraft. Four people will spend 10 days in orbit. In addition to various biomedical experiments, the team will perform work on the TESSERAE program.
TESSERAE is a research program whose ultimate goal is the self-assembly of structures in space. Its individual modules will be densely packed at launch, but once activated will form a robotic swarm suitable for self-assembly of various elements.

Storms and cyclones on Jupiter from an altitude of 4,200 kilometers
The Juno spacecraft made its 38th orbit of Jupiter and took several high-quality images of both the gas giant and its satellite Io. The apparatus transmitted images to Earth from a distance of 780 million kilometers.
Because of Jupiter's strongest radiation, Juno constantly has to orbit the planet and not come close. This time, the apparatus was able to approach the planet at a distance of 4,200 kilometers and captured on camera clouds, cyclones, storms and the northern part of Jupiter ☺️

Neptune's rings were first observed in 1968
Scientists believed they were incomplete ring segments. It was suspected that they might have gaps in the 1984 eclipse experiment. When Neptune passed in front of the star, there were flickers. But when it passed again, nothing was noticed.
The problem was solved in 1989, when the Voyager 2 spacecraft approached the Neptune system. The rings were lumpy, which is still a mystery. Perhaps there is a strong impact from the satellites. The ring system is thin and murky. It is believed to be a mixture of ice and dark material with organic compounds.
Voyager 2 has noted five rings. It is thought that they are young and formed after the crash of a small satellite.

Western satellites are predicted to collapse 🛰
Academician Herbert Yefemov predicted the rapid deterioration of Western satellites - we are talking about more than 2,000 apparatuses of the American Starlink constellation and more than 400 apparatuses of the British OneWeb.
"In a decade, these satellites will break down, becoming just unmanageable junk and creating an unprecedented congestion of narrow orbital layers with space debris, with an uncontrollable increase in the number of collisions," he said.
Efremov also noted that satellite constellations will be renewed, and this, in turn, will lead to a further increase in the number of new devices on the Earth's orbit.

One of the first to suggest launching something like a satellite into space was the science fiction writer
In 1945, Arthur Clarkson suggested that a satellite could be placed in orbit in such a way that it would move in the same direction and at the same speed as the Earth. So-called "geostationary satellites" could be used for communications.
Scientists did not get Clarkson - until October 4, 1957.

A needle in a haystack: scientists found another candidate for exoplanets
Kepler-1708 b - a gas giant about the size of Jupiter and 4.6 times its mass, removed from the parent star at 1.6a.u. One turn around the exoplanet makes for 737 days.
The supposed exolune Kepler-1708 bi is huge - its radius is 2.6 times the radius of Earth. Satellite orbits the planet with a period of 4.6 days and removed from it more than 740 thousand kilometers - almost twice as far as the moon from Earth.

FSSAI tells manufacturers to remove claims of 100% fruit juice from labels of reconstituted juice
The word “reconstituted” must be mentioned against the juice that is made from concentrate.
The elephant trunk dark gas nebula in the IC1396 star-forming region of the Cepheus constellation
The Elephant Trunk nebula wriggles around an emission nebula and young star cluster in the IC 1396 complex, high in the sky in the constellation Cepheus. The cosmic elephant trunk, also known as vdB 142, is more than 20 light years long.
This color picture is composed of images taken with narrow-band filters that allow radiation from ionized hydrogen, sulfur and oxygen atoms to pass through.
It clearly shows bright bands that border cold interstellar dust and gas clusters. These dark, mustache-like clouds contain the raw material for star formation and conceal protostars behind layers of light-absorbing cosmic dust.

How to calculate the weight of a Steel/Iron plate?
Example:
Weight = Length x Width x Thickness x Density.
Where:
Length = 1.5 meters.
Width = 1 meter.
Thickness = 0.02 meters (20 mm)
Density of Iron/Steel = 7850 kg/m³
Therefore,
W=LxWxTxD (in meters)
Weight = 1.5 m x 1 m x 0.02 m x 7850 kg/m³ = 235.5 kg.
Example:
Weight = Length x Width x Thickness x Density.
Where:
Length = 1.5 meters.
Width = 1 meter.
Thickness = 0.02 meters (20 mm)
Density of Iron/Steel = 7850 kg/m³
Therefore,
W=LxWxTxD (in meters)
Weight = 1.5 m x 1 m x 0.02 m x 7850 kg/m³ = 235.5 kg.

A Hungarian psychologist named Laszlo Polgar theorized that anyone could become a genius because geniuses were made and not born.
To prove this, he used his own daughters as experiments and trained them to become great at chess. The three Polgar sisters then became chess prodigies, and the youngest, Judit Polgar, become a grandmaster at just age 15.
