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.

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.

In April 2022 the inhabitants of Earth will see a parade of planets 🪐 Beginning April 20, 2022, all residents of Earth will be able to observe four planets that will be located next to each other. These are Jupiter, Venus, Mars and Saturn. Astronomers have called this celestial phenomenon "parade formation". The main condition is clear weather. The best time to observe is around 4 a.m., just before dawn. The best day is April 22.

The California Nebula Also known to astronomers as NGC1499, the California Nebula is an emission nebula in the constellation Perseus, located about 1,000 light years from Earth. 🚀

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 ☺️

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.

The space around black holes is curved so that light rays can bend around them several times Thanks to this, the object behind the black hole may have several copies. If this object is a supernova explosion, it can be observed over and over again.

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.

What causes solar flares? These phenomena occur because the Sun has its own magnetic field. And flares occur in areas where magnetic fields of opposite polarity collide in a confined space. Even though we already realize what solar flares are, scientists still can't predict when they will happen. So they commonly take us by surprise.

What does a pulsar look like? If you peek at a pulsar in the sky, it appears to be an ordinary shimmering star following a certain rhythm. In fact, their light does not flicker or pulsate, and they do not appear to be stars. A pulsar produces two persistent narrow beams of light in opposite directions. The flickering effect is created because they rotate (lighthouse principle). At this moment the beam hits the Earth and then turns again. Why does this happen? The reason is that the light beam of the pulsar is usually not aligned with its rotation axis.
