Astronomy’s exoplanet boom has recorded 5,000 worlds

More than 400 years ago, Galileo broke man’s understanding of the earth when he realized that the Earth was not the center of the universe, and that our planet revolved around the Sun, proving that in the opinion of Nicolaus Copernicus from the 1500s exactly.

Just a hundred years ago, astronomers thought the Milky Way was the entire universe. It wasn’t until 1925, when Edwin Hubble was able to measure the distance to a star in what became the Andromeda galaxy, that man realized that our “earth” was the only galaxy inside. of the earth’s ocean.

And in 1995, astronomers saw the first exoplanet orbiting a star similar to the Sun in the Milky Way, reshaping our solar system in a different way.

Now, just a few years later, scientists have confirmed over 5,000 exoplanets in our galaxy. The latest story came on March 21 when 65 new exoplanets joined the NASA Exoplanet Archive. The archive combines exoplanet data printed on peer -reviewed papers and marks them as “verified” when seen and verified with a variety of methods.

“It’s not just a number,” Jessie Christiansen, scientific director for the library said in a press release. “Everyone is a new world, a new world. I’m happy with each one because we don’t know anything about them.
