Radiation of the sun
The radio emission of the Sun has two components - constant and variable. During strong solar flares, the radio emission of the Sun increases by a factor of thousands or…

The history of the discovery of Pluto

In the 1840s, with the help of Newtonian mechanics, Urbain Le Verrier predicted the position of the then undetected planet Neptune based on an analysis of perturbations of the orbit of Uranus. Subsequent observations of Neptune at the end of the 19th century led astronomers to suggest that, in addition to Neptune, another planet also has an impact on the orbit of Uranus. In 1906, Percival Lowell, a wealthy resident of Boston who founded the Lowell Observatory in 1894, initiated an extensive project to find the ninth planet in the solar system, which he named Planet X. By 1909, Lowell and William Henry Pickering had suggested several possible celestial coordinates for this planet. Lowell and his observatory continued to search for the planet until his death in 1916, but to no avail. In fact, on March 19, 1915, two low-level images of Pluto were obtained at his observatory without Lowell’s knowledge, but he was not recognized on them.

Mount Wilson Observatory could also claim the discovery of Pluto in 1919. That year, Milton Humason, on behalf of William Pickering, searched for the ninth planet, and Pluto’s image fell on a photographic Continue reading

Big Bang Scenario

Like any scheme that claims to explain the data on the spectrum of microwave cosmic radiation, the chemical composition of pre-galactic matter and the hierarchy of the scales of cosmic structures, the standard model of the evolution of the Universe is based on a number of initial assumptions (about the properties of matter, space and time) that play the role of original conditions for the expansion of the world. One of the working hypotheses of this model is the assumption of uniformity and isotropy of the properties of the Universe throughout all stages of its evolution.

In addition, based on data on the spectrum of microwave radiation, it is natural to assume that in the Universe in the past there was a state of thermodynamic equilibrium between plasma and radiation, the temperature of which was high. Finally, Continue reading

Uranus and Neptune

Uranus is the seventh planet from the Sun in the solar system. In diameter, it is almost four times larger than the Earth. Very far from the Sun and relatively poorly lit. Uranus was discovered by the English scientist W. Herschel in 1781. It is not possible to distinguish any details on the surface of Uranus due to the small angular dimensions of the planet in the field of view of the telescope. This complicates his research, including the study of the laws of rotation. Apparently, Uranus (unlike all other planets) rotates around its axis as if lying on its side. Such an inclination of the equator creates unusual lighting conditions: at the poles in a certain season, the sun’s rays fall almost vertically, and the polar day and polar night cover (alternately) the entire surface of the planet, except for a narrow strip along the equator. Since Uranus Continue reading
