Hubble Space Telescope
From the very beginning of astronomy, from the time of Galileo, astronomers have one common goal: to see more, to see further, to see deeper. And the Hubble Space Telescope,…

Star evolution
Like all bodies in nature, stars do not remain unchanged, they are born, evolve, and finally "die." To trace the life path of stars and understand how they age, you…

Atmosphere of the Moon and Moon Space

Since the mass of the moon is negligible, the gas shell around it must be very rarefied, i.e. practically absent. The main components of the gas shell were hydrogen, helium, neon, and argon. The highest density is observed at night and corresponds to about 2 · 105 cm – 3. in the daytime, the gas concentration drops to 104 cm – 3 in terms of density at the surface. Therefore, we can speak with good reason about the presence of some kind of gas shell around the moon.
The moon has practically no global magnetic field of a dipole nature. This circumstance explains the peculiarities of the interaction of the Moon with the stream of charged particles of the solar wind, which consists mainly of protons and electrons with the addition of ionized helium and other heavier elements with different degrees of ionization. The moon is a non-magnetic, relatively non-conductive and cold dielectric sphere. Continue reading

A new level of evolution

Millions more years pass by. Nature “found” the best amino acid sequences in the chains of polypeptides – protein molecules appeared – the future bricks of living organisms. Replication has become more sophisticated and improved. The matrix is ​​no longer a mechanical form, but a conventional, chemical “record” of the order of amino acids in a protein molecule. Record in the form of a portable chain of special molecules – nucleotides. The evolution of matter rises to a new level. Long, bizarrely curved strands of different protein molecules cling to each other and gradually assemble. First into small lumps, then into larger lumps that look like tangles or drops. Molecules that are closely in contact in a lump have Continue reading
