The youngest exoplanet in the Universe has been discovered
Astronomers have confirmed the discovery of the youngest known exoplanet, Elias 2-24 b, which is less than a million years old. This finding provides valuable insights into the early stages of planet formation.
Cursus
Every year, numerous exoplanets are discovered with the help of telescopes, but some of them stand out due to their unique characteristics. One such example is Elias 2-24 b—the youngest exoplanet identified to date.
Confirmation of Discovery
To confirm the existence of this exoplanet, researchers analyzed archival data from the W. M. Keck Observatory in Hawaii. Using a coronagraph, they studied seven stars surrounded by disks of gas, dust, ice, and rock. By blocking out the starlight with the coronagraph, they were able to detect the object Elias 2-24 b, which orbits the star Elias 2-24.
Characteristics of the Exoplanet
The mass of Elias 2-24 b is estimated to be between 1.9 and 4 times that of Jupiter. The distance from Earth is approximately 450 light-years. The planet’s age is believed to be less than a million years, making it the youngest known exoplanet.
Further Research
The age and mass of Elias 2-24 b provide a unique opportunity to study the early stages of planetary formation. To better understand the nature of this object, additional archival observations from 2018 and 2020 were analyzed. A combined analysis of the data showed that the object behaves like a planet, confirming the discovery.
Prospects for Future Discoveries
In the coming years, it is likely that even younger exoplanets will be found. The launch of the Nancy Grace Roman Space Telescope, scheduled for August 30, 2026, will enable the use of a coronagraph to search for new worlds.
