Because Earth, by far the only planet known to have life, orbits the Sun, planetary systems around stars of similar size and type are logical targets for astronomers looking for extraterrestrials.
A new study published in the journal Nature suggests that planets in binary systems built around sun-like stars could be great targets in the search for extraterrestrial life, which could bring humanity the desired result.
Researchers believe that worlds revolving around binary systems, which consist of two stars locked in gravitationally and orbiting one another, may be the best way to research, according to the University of Copenhagen researchers, more than half of the stars the size of the sun are in binary systems, where energy supplies the region Habitable to the outside and make it bigger.
The results determined that these stars are heating each other’s worlds, increasing the chances of orbiting a planet with liquid water.
Professor Jess Christian Jorgensen, one of the study’s lead authors, said: “The result is exciting because the search for extraterrestrial life will be equipped with many very powerful new tools over the coming years, and this reinforces the importance of understanding how planets form around different types of stars. Findings such as these may identify places that would be particularly interesting to look for the presence of life.”
In their study, the researchers note that the discovery is based on observations of a young double star about 1,000 light-years from Earth by the Atacama Telescope in Chile, known as NGC 1333-IRAS2A surrounded by a disk of gas and dust, so the researchers developed a computer simulation that travels back and forth in time.
The rotation of gas and dust, for example, does not follow a consistent pattern, becoming very strong for “relatively” short periods of time over thousands of years, and the binary star brightens up to a hundred times before returning to its original state, since the two stars surround each other, researchers believe that This periodic pattern can be explained by duality.
The joint’s gravity will affect the surrounding disk at regular intervals, causing massive amounts of debris to fall toward the star.
“The observations allow us to zoom in on stars and study how dust and gas move toward the disk, and the simulations will tell us about the physics at play, how stars evolved, right up to the snapshot we observe and their evolution in the future,” said co-author Dr. Rajika Kuroeta.
However, the star system in question is still too young for planets to form, according to the study.
“Comets are likely to play a major role in creating the potential for life to develop,” Jorgensen said in the report. “Comets often contain a high percentage of ice with organic molecules.” “It can be imagined that organic molecules are preserved in comets during the eras when the planet is barren, and that the effects of subsequent comets will introduce the molecules to the surface of the planet, and the heating caused by the explosions will lead to the evaporation of the surrounding dust and ice grains, and this may change the chemical composition of the material that composes it. Planets, and the wavelengths covered by the telescope allow us to see very complex organic molecules, and therefore molecules that contain 9-12 atoms and contain carbon, can be building blocks for more complex molecules that are the key to life as we know it, for example, acids amino acids found in comets.
