What would be a “tail” on the moon?
The Moon has a comet-like tail and every month it kills a ray around the Earth. By this animation @physicsJ Of Jodi. Based on Wilson’s simulation, it shows how the sodium atoms extracted from the lunar surface are affected by the lunar orbit around the planet Earth. https://t.co/hrFhlwg1FZ pic.twitter.com/SIGfVqOXVo

14 years later, researchers finally discovered why our moon has a “tail”, more or less like a comet – invisible to the naked eye only. The team proposed that the incident may be due to the impact of space objects on our natural satellite.
When these rocks reach the Moon, the effect causes sodium atoms to be taken into orbit, where they collide with photons coming from the Sun. Therefore, it forms a tail-like structure – which, in this case of the moon, greatly expands. , Without the risk of particles reaching the Earth.

Powerful meteor in the american sky
Who was thinking of the big boom / meteor earlier, for today #Btv #Anwar , I dug through some webcam footage and found it on the WCAX / BTV airport webcam – upper left view. pic.twitter.com/oyVLSoVahP

In the state of Vermont, residents were so shocked by a loud bang as well as a vibration that it felt as a jolt throughout the body. All this was the result of the entry of a space object into the Earth’s atmosphere, which became a powerful meteor – moving at a speed of 19 km / h, the rock with an energy equivalent to 200 kg TNT broke!
“Percy” analyzes first on Mars
Peseverance Rover’s Supercam has already begun its scientific activities, revealing the capabilities of its infrared sensor and its spectrometer. Responsible for collecting sunlight to study the mineral content of rocks and sediment, the first is called VIRIS; The second is called Raman, which launches a green laser to heat chemical bonds and, from there, provides information about the composition of the observed material.

And, in addition to giving Start On his camera, Perseverance has also recorded his first sounds of Mars – particularly the sounds of Mars winds and laser-generated “pop” when it hits a cliff. listen!

A mysterious cloud was seen on Mars
In 2018, the Mars Express spacecraft spotted long, thin clouds on Mars, which surprised many. Now, scientists have found that these seasonal clouds (which reappeared last year) were made up of ice particles.
When spring comes to the south of Mars, it brings with it a mysterious cloud that rises next to a volcano made of frozen water. The cloud spreads for a few kilometers and then disappears in a few hours.

The picture of the largest asteroid that will pass us in 2021
On March 21, the largest asteroid will make its approach to Earth to “trip” us this year. Object (231937) 2001 FO32 has an estimated diameter of 0.8 to 1.7 km, but, even though it is listed as potentially dangerous, this time it will not present any risk to our planet.
And when it was about 20 million miles from Earth, the asteroid was recorded through the lens of the Virtual Telescope Project, which appeared as a small white spot in the middle of the stars.

First images of Brazilian satellite Amazonia-1 released
Still in the testing phase, 100% Brazilian satellites have already released their first pictures of the Earth. It was launched only in February to observe our planet, specifically to monitor deforestation in the Amazon region.

This exoplanet lost its environment, where it created a new one
The rocky planet GJ 1132b was identified in 2018, and two years later, scientists discovered an atmosphere around it. Now, using the Hubble Space Telescope, astronomers have found evidence of volcanic activity there, which would in fact be responsible for creating a second atmosphere.
At first, GJ 1132 b appears to be a gaseous planet, surrounded by a thin layer of hydrogen and helium atmosphere. Sometimes this feature earned him the title of “Sub-Neptune” due to the radius of our planet. Over time, this interstellar atmosphere began to lose due to the intense radiation action emitted by the orbiting star, and eventually, the gas planet was reduced to a pure nucleus, approximately the size of Earth, becoming, then, one on our planet We have a rocky world with equal size and density.
Then, Hubble demonstrates that a secondary environment is visible there, lost in the past.
