What we know about Venus in two phrases
Venus, or rather its surface is always hidden behind a curtain of thick clouds, which makes it difficult to observe the second planet from the sun. Due to the density of clouds, it is inaccessible by any powerful ground-based telescope. However, using radar technology, the launches of automatic stations to this planet have long received…

What is in the center of the Earth? How do we know that
Since it is not yet possible to directly penetrate very deep into the bowels of the Earth, some indirect methods are used to study the contents of the Earth’s interior. The study of volcanic eruptions, emissions of incandescent gases and molten rock to the surface indicates that it is very hot inside the Earth. During…

An unusual layer of metals was found in the gas shell of Jupiter
In astronomy, metals are elements heavier than hydrogen and helium. Researchers have built a number of theoretical models describing the structure of Jupiter’s gas envelope. It turned out that in the direction of the center of the planet, the metal content increases dramatically. A gas giant like Jupiter can acquire metals in two ways during…

In the neighboring system , at a distance of 12.5 light-years from us , two exoplanets as similar to Earth as possible have been discovered
The discovered exoplanets, called Teegarden b and Teegarden c, are only slightly larger than our Earth, but in general they resemble it very much. Teegarden b even took first place in the list of potentially habitable exoplanets, scoring the highest score on the Earth similarity index. This index is used to approximate the suitability of…

Flag of the Earth
Before the astronauts landed on the moon, there was an opinion that the first people on the satellite should leave there not an American flag, but a flag representing all of humanity. And although these few voices were not heard, in 1970 they pushed James Cadle, who lived on a farm in Illinois, to create…

Why has man never flown to the dark side of the moon?
The answer, in fact, is simple: there is no radio communication with Earth on the other side. This problem can be solved by grouping satellites that will forward the signal, but it is expensive and difficult. And without constant communication, putting people on the moon is an excessive risk. Of course, now I’m talking about…

On the exoplanet WASP-31b found a substance that is both liquid and gaseous
Researchers have found evidence of the presence of chromium hydride on the exoplanet WASP-31b, which at a certain temperature and pressure is at the boundary between liquid and gas. On Earth, it resembles clouds and rain. Chromium hydride can play a role in the formation of the weather system on this planet: clouds and rain…

Rock analysis has shown that Mars used to resemble Iceland
The ancient Martian Gale crater became the center of research by scientists who compared the data of the Curiosity rover with places on Earth where similar geological formations eroded in different climatic conditions. The basalt relief of Iceland and the cool weather with temperatures, as a rule, below 3 °C turned out to be the…

A unique neutron star was found in the “galactic cemetery”
The MeerKAT radio telescope has discovered a new type of neutron star. It rotates extremely slowly, making one revolution in 76 seconds. The authors believe that a new class of neutron stars has been found. The unique neutron star was named PSR J0901-4046. A neutron star emits at least seven different types of pulses, some…

China targets permanently shaded regions at the Moon’s south pole
China is seeking to land spacecraft near permanently shadowed regions near the moon’s south pole to investigate the potential presence of resources trapped in craters. In such places, the temperature is about -230 degrees Celsius, colder than the surface of Pluto, which makes them potential traps for volatile substances, including water ice, as well as…
