Over 200 New Planets Found By Astronomers In 2022

In an enormous discovery, astronomers discovered over 200 new planets exterior our photo voltaic system. In 2022 alone, astronomers found fewer than 5,000 exoplanets. And by the tip of 2022, the quantity has grown to five,235 exoplanets. 

The launch of the James Webb Area Telescope has helped the hunt to find extra exoplanets. Probably the most highly effective observatory despatched into area succeeded the Hubble telescope, which continues to be working, and commenced transmitting its first cosmic photos in July. One of many foremost objectives of the $10-billion telescope is to review the life cycle of stars. One other foremost analysis focus is on exoplanets, planets exterior Earth’s photo voltaic system.

In a tweet, NASA stated, “We began the 12 months with fewer than 5,000 confirmed exoplanets. We finish with 5,235 identified worlds. About 4% are rocky planets like Earth or Mars. What’s going to the brand new 12 months deliver? Extra planets!”

Exoplanets have a diverse vary of worlds relating to their composition and traits. Whereas some are small and rocky, different seems so much like Earth. 

Astronomers found the newest planet in 2022, named HD 109833 b, it’s a Neptune-like exoplanet that orbits round a G-type star. The astronomers discovered it utilizing the transit technique. 

In a latest discovery, astronomers discover that two exoplanets could also be largely water. Water wasn’t straight detected, however by evaluating the sizes and much of the planets to fashions, they conclude {that a} vital fraction of their quantity — as much as half of it — ought to be fabricated from supplies which can be lighter than rock however heavier than hydrogen or helium (which represent the majority of fuel large planets like Jupiter). The most typical of those candidate supplies is water.
