Historical milestone: Over 5,000 planets have been discovered outside the solar system

A historic milestone in space exploration: NASA has announced the discovery of 65 new extrasolar planets, thus crossing the continent of 5,000 verified extrasolar planets in a 30-year study.

The first discovery occurred in 1992, when three celestial extrasolar planets orbiting a pulsating neutron star were identified. Today, the database in NASA’s official archive stands at 5,005 solar extraterrestrial planets, all of which have appeared in peer-reviewed articles and received approval after using a variety of detection methods and analytical techniques. Most of the stars are up to 3,000 light-years away.

The list includes small rocky stars such as Earth, giant rocky stars called “Super Earth”, gas giants larger than Jupiter, “Hot Jupiter” stars that orbit near their own stars and smaller stars from the planet Neptune. Last month it was even reported that an extrasolar solar planet 855 light-years away has clouds made of metal and rains made of liquid gems.

“It’s not just a number,” explained Jesse Christiansen, chief scientist at the Solar Planet Archive, who also serves as a scientist at NASA’s Solar Planet Research Institute at Cal-Tech in Pasadena. “Each one is a whole new world.”

The search for extrasolar planets has gained momentum thanks to the Kepler Space Telescope, which has been operating since 2009, and the research satellite for extrasolar planets (TESS), which has been operating since 2018. The James Webb Space Telescope, which is in the final preparations for launch, is expected to detect new worlds.

NASA is expected to launch the Nancy Grace Roman space telescope in 2027. It will also search for new stars. The European Space Agency’s Ariel mission, which is expected to be launched in 2029, will focus on studying the atmospheres of extrasolar planets.
