"Baby alien worlds are indeed likely slicing gaps in the disk of dust and gas swirling around the young star HL Tauri — a finding that could help reshape scientists' current understanding of how planets form.
Astronomers found that some of the rings in the disk's gaseous component line up with rings in the dust, further supporting the theory that exoplanets are coalescing there — and suggesting that alien worlds may form much more quickly than scientists had thought.
"To our surprise, these gaps in the gas overlap with dust gaps," lead author Hsi-Wei Yen, a researcher at the Academia Sinica Institute of Astronomy and Astrophysics in Taiwan, said in a statement. "This supports the idea that the gaps are the footprints left by baby planets. Our results indicate that planets start to form much earlier than we expected."
