Through the world’s largest radio telescope ALMA system located in Chile, astronomers captured for the first time beautiful images of an amazing astronomical phenomenon: the birth of an alien hundreds of light-years from Earth.
The photo, which was published in Astronomy & Astrophysics on May 20, shows a spiral structure appearing inside the dense dust and gas disk surrounding the star AB Aurigae. This is a young star, located 520 light-years from Earth (about 4.94 million billion kilometers), in the constellation Auriga. AB Aurigae is located in an area called the ‘star nursery,’ filled with gas and cosmic dust.
The spiral structure appears inside the dense dust and gas disk surrounding the star AB Aurigae.
According to the European Space Research Organization in the Southern Hemisphere (ESO), the spiral structure surrounding AB Aurigae is a sign that a planet is slowly taking shape.
“Thousands of exoplanets have been found so far, but few know how they formed“, Said Anthony Boccaletti, an astronomer at the Paris Observatory (France).
“It takes millions of years for a planet to reach the final stage of formation. Therefore, we cannot determine the exact time of birth of a planet. However, we can confirm that we almost caught the moment a planet was in the process of forming“This study could help scientists better understand how planets are formed from the condensation of dust and gas in the disks of dust and gas around young stars.
Further, the distance between the ‘newborn’ planet is forming and its host star is approximately the distance from Neptune to the Sun. Astronomers say this is not a rocky planet like the Earth, but a gas planet. It may be heavier than Jupiter – the largest gas planet in the solar system.
