Space Research: Solar EclipsesOn April 23, 1996, the PRIRODA international experiment was orbited. This experiment module is design ted to work together with the MR orbital station. The Multichannel Infrared Spectrometer ISTOK-1 is one of the devices used in the experiment ISTOK-1 measures the ...

Total solar eclipses have not always been visible from Earth. In the past, the Moon was too close to Earth and during eclipses it completely blotted out the Sun’s disk. Over time, the lunar orbit has changed at the rate of just over 2 cm per year and in the current epoch, the al...

Francis Baily was an astronomer who detected the phenomenon called “Baily’s beads” during an annular eclipse of the Sun on May 15, 1836. His vivid description aroused new interest in the study of eclipses. Baily retired from a successful business care
Solar eclipse, the Moon coming between Earth and the Sun so that the Moon’s shadow sweeps over Earth’s surface. This shadow consists of two parts: the umbra, a cone into which no direct sunlight penetrates; and the penumbra, which is reached by light f
From Earth, we can see two types of eclipses—eclipses of the Sun (solar eclipses) and eclipses of the Moon (lunar eclipses). These occur when the Sun, Earth, and the Moon align in a straight or almost straight configuration. Astronomers call this asyzygy, from the ancient Greek words...

The nitty-gritty of the 2024 solar eclipse Every eclipse has a different length of totality. This is caused by the nature of the cosmos as Earth and the Moon orbit not in perfect circles, but ellipses — so Earth is not always the same distance from the Sun and the Moon is not always...
