Definition of graviton

A graviton is a hypothetical particle that is postulated in quantum field theory to mediate the fundamental force of gravity, similar to how the photon measured the electromagnetic force. In the framework of quantum theory, the graviton would be a massless spin 2 particle. However, until […]

Definition of astrophotography

Astrophotography is the result of the combination of knowledge, interests and actions that are linked to both astronomy and the field of image capture. In this discipline, therefore, art and science are combined with extraordinary results that, simultaneously, teach and amaze. As the years went by […]

Definition of galaxy formation

The formation of galaxies is the subject of study and monitoring by scientists specialized in the field of astrophysics. Although there are still numerous enigmas to be deciphered in this regard, thanks to continuous research and the advancement of technology, information linked to both the birth of the universe and also the […]

Definition of neutron stars

Neutron stars are, according to scientists specialized in astronomical matters, a type of stellar remnant that emerged as a result of the gravitational collapse of massive supergiant stars. This phenomenon is triggered once they exhausted the fuel present in their cores and exploded like a supernova in one of their […]

Definition of blue giant

Blue giant is a star with high luminosity and a high surface temperature. Most of them are of spectral class B, although there are also some of spectral type O (such as the case of HD164492A belonging to the open star cluster called Collinder 360, in the Trifid nebula). They usually have an absolute magnitude of between […]

Definition of cosmic radiation

Cosmic radiation is a highly energetic form of radiation that comes from outer space. These are cosmic rays composed mainly of protons, helium nuclei and other subatomic particles. They originate from various cosmic sources, such as supernovae, black holes, and other extreme astrophysical events. Upon reaching Earth, they interact with the atmosphere, […]

Definition of space observatory

A space observatory is a scientific facility located in outer space designed to observe astronomical phenomena without the distortions caused by the Earth's atmosphere. These observatories can be in orbit around the Earth or other celestial bodies, and are often equipped with telescopes and other advanced instruments to capture data at different longitudes […]

Biography of Galileo Galilei

Galileo Galilei is the identity of a multifaceted man born in Italy who, for his valuable discoveries and achievements, is recognized universally as "the father" or main exponent of modern science. His arrival into the world, according to records, occurred on February 15, 1564 in Pisa, while […]

Definition of planetary nebula

A planetary nebula is something that forms in interstellar space based on interstellar dust and gas from the exhaustion of a star's fuel. When it, now without hydrogen available and appealing to the helium reserve, cannot resist the weight of its own mass, it becomes […]

Definition of Venus

Venus is a term with different meanings depending on the context: astronomy: Venus is the second planet in the solar system. It is considered the sister planet of Earth, and is located between it and Mercury. It is known for being the brightest apparent object in the sky after the Sun and Moon. Venus has […]
