Venus' long term fluctuations in its climate are reflected in its climate
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...

Life on Mars can be spread by the wind!
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...

What is the star value?
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"...

Giant galaxies have been discovered that cannot yet be explained!
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...
