The Hubble Space Telescope has peered out into the cosmos and spotted its youngest exoplanet yet, a giant world 379 light-years from Earth that's still growing.
Planets form as dust and gas, swirling around in a circumstellar disk surrounding their star, collides and condenses to slowly become a "ball." Far out in the constellation Centaurus, Hubble has spotted a planet still coming together. The young gas giant exoplanet, designated PDS 70b, is "just" 5 million years old, Hubble scientists said. While the planet is still gathering mass, pulling it from the young star it orbits, it's already huge — roughly the size of Jupiter.
In a new study, scientists took advantage of this unique opportunity to study a planet in its formative years like PDS 70b with Hubble's telescope eye. .
"This system is so exciting because we can witness the formation of a planet," co-author Yifan Zhou, also of the University of Texas at Austin, said in a statement. "This is the youngest bona fide planet Hubble has ever directly imaged."
