For 10 years, scientists have been observing the state of the Venus atmosphere using sensors installed on spacecraft. As a result, it became clear that an important cause of cyclical climate change is the long-term fluctuations of the planet's albedo (reflectivity), which in turn is related to the number of mysterious dark spots in the atmosphere of Venus. These spots absorb solar radiation much more effectively than the surrounding lighter clouds, but their nature is not yet clear. According to...

The driest desert on Earth continues to tell us about the potential of Martian life. Microbial life on Mars can spread all over the planet, moving on dust particles raised by the winds. This is the conclusion of scientists led to the observation of microorganisms in the desert Atacama, whose climate is incredibly dry and strongly reminiscent of the Martian. The results of the study are presented in the journal Scientific Reports. "To understand whether microbial life can move through the Atacama...

On a dark, clear night away from the city, thousands of stars can be seen in the sky. The first thing that strikes the eye is that they all differ in brightness or, as astronomers say, brilliance. Astronomers have long ago learned to accurately determine the shine of stars and other celestial lights. A stellar value is one of the oldest measurement standards we use. For the first time this term was used by the great astronomer of antiquity Hipparkh (130 BC). Hipparch decided to divide all the stars in the sky by their brightness into six groups or "values"...

The discovery calls into question the modern understanding of the early universe. Using an array of radio telescopes ALMA, astronomers identified 39 extremely dim and massive galaxies, which escaped even from the sharp vision of the space telescope "Hubble". Scientists assume that these ancient relics are the ancestors of the elliptical galaxies observed today, but none of the modern theories of evolution of the universe can explain such many large starry megacities at the dawn of the universe. The results of the study are presented in the journal Nature...

Https://rusargument.Ru/data/photo/062919_055320216126.Jpg Representatives of NASA and the ESA held a meeting of the Working Group on the study of Mars (mepag) on July 26, during which they discussed some details of the plan for the delivery samples of Martian soil to the Earth...

Today, several ways have already been announced for direct study and analysis of objects that originate outside the solar system, and now our satellite is in the same row with them. Since the Moon is practically devoid of atmosphere and is a geologically quiet world, its surface can be in the public domain with a large amount of extraterrestrial material and building blocks of extraterrestrial life, scientists say in the study, presented on the server of preprints arxiv org. "We predict that the...

At the moment, the main problem of this pair of famous probes is the gradual decline in the power of their RITEGs (radioisotope thermoelectric generators), which currently produce only about 40% of the original electrical power of 470 watts (which corresponded to about 7 kW of thermal power). Their electricity is used for two purposes: to power scientific instruments, to heat them, and to heat other important parts of the instruments in the cold of deep space. 6 out of 11 scientific instruments...

Https://taspo.De/fileadmin/_processed_/0/6/csm_eden-iss_august2019_2_9af17513c9.Jpg The German Centre for aviation and aerospace (DLR) has been working on the EDEN-ISS project in Antarctica for some time now to find out how food production may look in life-threatening conditions in the future...

The age of Saturn's rings is a longstanding subject of debate among planetary scientists. Some believe that they were formed along with the giant 4.5 billion years ago from the ice fragments left in orbit after the formation of the solar system. Others say that the rings are very young and that Saturn at some point seized an object from the Kuiper belt or comet and then gradually "crushed" him or her into a cluster of debris in his or her orbit. Now, this argument is most likely to have a dot in it...

We have a planet near us that looks very much like our own. Venus and Earth are about the same size and formed from the same materials around the same star. Indeed, an alien astronomer observing these two planets from another star system at a distance of a few light-years from us would not see the difference between Venus and Earth. But if you know something about the conditions on the surface of Venus, you realize that it is not like the Earth at all. The temperature is like in a self-cleaning furnace, the atmosphere is made of carbon dioxide, sulfuric acid clouds...
