The magnetosphere is a region around a celestial body, such as Earth, dominated by its magnetic field, which acts as a protective barrier against charged particles from the solar wind and cosmic radiation. This magnetic bubble deflects and traps particles, creating structures such as the Van Allen belts and visible phenomena such as […]

The inflation theory is a cosmological model that proposes a rapid exponential expansion of the universe during its first moments, immediately after the Big Bang. This cosmic inflation phase would have occurred in a fraction of a second and explains several problems in the standard Big Bang model, such as temperature uniformity […]

An elliptical orbit is the elliptical path that an object follows around a central point due to the influence of gravity, as happens with the planets around the Sun. In this type of orbit, the distance between the object and the center Attraction varies, being lower at perihelion […]

A white hole is a region of space-time that constantly repels and ejects matter. It is, therefore, the opposite of a black hole (which attracts matter due to its immense concentration of mass). At the moment, the existence of white holes has not been demonstrated, which constitutes […]

Time dilation is a phenomenon predicted by Einstein's theory of relativity, in which time passes more slowly for an object in motion relative to an observer at rest. This occurs because, at speeds close to that of light, time stretches or dilates, […]

Anthropic principle is an expression that encompasses an idea whose content can be approached or analyzed from cosmology and physics, as well as from theology and philosophy. This concept that gained relevance after being pronounced in a symposium by an expert in theoretical physics who was born in […]

Space station is the name given to each structure or platform that is designed for research purposes and to house a laboratory module intended to carry out studies and experiments that are useful for multiple space vehicles. It should be noted that space stations, throughout history, have been created with both […]

The observable universe refers to the portion of the universe that we can observe and study from Earth, limited by the speed of light and the time that has passed since the Big Bang. Because light has a finite speed, we can only see objects whose light has had time to arrive […]

The solar wind is radiation that is continuously emitted by the Sun. Made up mainly of protons, it also contains electrons and other components and propagates in all directions. The release of these charged particles occurs in the solar corona, which is the outer layer of the star. In fact, it is considered that […]

Uranus is the seventh planet in the solar system, located about 2.9 billion kilometers from the Sun. It is an ice giant, composed mainly of hydrogen, helium and compounds such as water, ammonia and methane. Uranus is known for its blue-green hue, a result of methane in its atmosphere absorbing red light. TO […]
