Conception art no longer

Summary: The Alma telescope has captured a first image of its kind. A picture of planetary formation. The star is HL Tau and here we can see the protoplanetary disk that has formed around the star. It is out of this that the planets are formed. The dark rings in the image are the paths carved out by new planets being formed. Astronomers were surprised by how quickly the process was taking place; HL Tau is only about a million years old. It was not expected to have planets forming yet. This adjustment in the timescale of planetary formation could have an impact on how we date our own solar system, and now that we know it forms faster than expected, we might train our telescopes on other stars around this age and hope for similar results.
