An exoplanet with its own magnetosphere.  The first discovery of its kind by the Hubble Space Telescope

An exoplanet with its own magnetosphere. The first discovery of its kind by the Hubble Space Telescope

These observations were made by scientists from University of Arizona Lunar and Planetary LaboratoryWho covered the details in an article published in the magazine natural astronomy. The report shows that she mentioned The exoplanet is 123 light years from EarthAnd the use of ultraviolet radiation to detect the magnetosphere – the Hubble Space Telescope HAT-P-11b observed in a spectrum of ultraviolet light, which exceeds the human eye.

Device detected carbon ions, that is, the particles interact with the magnetic field that surrounds the planet as if there were space (a bubble) floating on top of it. to gildy blazer And her team at the University of Arizona, it was clear that the magnetosphere had been detected above HAT-P-11b.

Ballast Notes. However, the processes occurring in the Earth’s magnetosphere and HAT-P-11b are almost the same The proximity of an exoplanet to the central star of the system It causes the upper atmosphere to heat up and “evaporate” into space, resulting in the formation of a characteristic magnetic tail. While the presence of a magnetosphere may indicate that the planet has a chance for life to develop, it is worth noting that this has not been 100% confirmed and requires further observations.

“The atmospheric composition that we observe at HAT-P-11b indicates that more work is needed to improve current theories about the general composition of some exoplanets,” Ballaster adds. At the same time confirms it Using ultraviolet light could help detect magnetospheres on other exoplanets or determine if they are habitable..

We have currently detected from 4.3 to 4.7 thousand. of these types of objects in our galaxy, and recently The Kepler space telescope helped add a few hundred more to the list.
