First magnetic field discovered on an exoplanet

Recently, a team of astronomers used data from the Hubble Space Telescope to search for signs of a magnetic field on an exoplanet. Its findings were described in the journal Nature Astronomy.

A magnetic field around the planet explains the observation of an extended field of charged carbon particles.
Magnetic fields play an important role in protecting the planet’s atmosphere.

Researchers used Hubble to observe the exoplanet HAT-P-11b. It is a Neptune-sized planet, located at a distance of 123 light years from Earth.

The outer planets are the planets outside our solar system. The first possible evidence of an outhouse was found in 1917, but this was not recognized. The first confirmed outhouse was discovered in 1992. As of December 2021, there are 4,878 confirmed extraterrestrials located in 3,604 planetary systems. Of all the systems, 807 systems have more than one planet.

There are several ways to locate the outhouse. But transit photometry and Doppler spectroscopy have made the most of the discoveries.
