NASA Confirms Over 5,000 Planets Outside Solar System


According to NASA, the total number of known planets in the cosmos surpassed 5,000 this week, thanks to the discovery of 65 exoplanets that were discovered. According to the space agency, the verified planets represent just a tiny proportion of the billions of planets that the Milky Way Galaxy is believed to contain. When we take into account galaxies other than our own, that number only goes up.

Several detection techniques, as well as peer-reviewed scientific articles, were used to validate the existence of the newly discovered exoplanets — worlds that live beyond our solar system, according to NASA. On Monday, they were officially added to the NASA Exoplanet Archive.

According to Jessie Christiansen, scientific lead for the archive and a research scientist at the NASA Exoplanet Science Institute at Caltech in Pasadena, Calif., “it’s not just a number.” “It’s not just a number,” she said. “Each of them is a whole different world, a completely different planet. Because we don’t know anything about them, I become enthusiastic about each and every one of them.”

When it comes to the thousands of exoplanets that have been discovered outside of our solar system, many are small, rocky worlds similar to Earth, gas giants larger than Jupiter, “hot Jupiters” that rotate in close proximity to their stars, super Earths, mini Neptunes, and some that continue to revolve around collapsed, dead stars.

It was in 1992 when the discovery of three planets circling a neutron star known as a pulsar was discovered, marking the first time that planets beyond our solar system had been proven by science. Pulsars are very rapid rotating objects that emit “searing radiation” on a regular basis, according to NASA.

In the words of Alexander Wolszczan, the author of the study that discovered the first three planets, “If you can locate planets near a neutron star, planets have to be virtually everywhere.” “The technique of creating the planets must be very strong.”

As anticipated by Wolszczan, the recently launched James Webb Space Telescope will herald the beginning of a new age of discovery, which will result in the addition of even more planets to the NASA Exoplanet Archive.

The James Webb Space Telescope (JWST), which was launched on December 25th, is the most powerful telescope ever sent into space, and it will employ infrared technology to see things that have never been seen before. In the hopes of receiving photographs of the universe’s initial stars and galaxies — as well as exoplanets — the telescope will be launched in 2009.

“I believe it is inevitable that we will come across some kind of life someplace — most likely of a rudimentary nature,” Wolszczan added.

NASA revealed the first picture taken with the new telescope after refining its focus last week — a beautiful, blazing orange star known as 2MASS J17554042+6551277 — which was taken with the new telescope after refining its focus. The photograph also showed a number of galaxies in the backdrop of the star, none of which have been named as of yet.
