It's Official: Astronomers Caught The First-Ever Direct Picture of a Planet Being Born
For the very first time, astronomers have captured an image of a baby planet as it carves a path through the disc of dust that surrounds its star, an orange dwarf 113.4 parsecs (370 light-years) away from Earth.
[...] PDS 70 has a few features that made it a good candidate for this sort of search. Its protoplanetary disc is large, spanning a radius of around 130 astronomical units (the distance between Earth and the Sun; the Kuiper belt only goes up to about 50 au).
[...] Using its coronagraph and polarisation filters, the [Very Large Telescope] team discovered a very large planet orbiting in the gap in PDS 70's protoplanetary disc - which means it's probably still in the process of accumulating material. Further analysis of the planet, described in a second paper, was conducted based on its spectrum. Its mass is several times that of Jupiter, and its orbit is around 22 AU, just a little bit farther than Uranus's orbit around the Sun. It takes about 120 Earth years to complete one orbit around its star, and its surface temperature is around 1,200 Kelvin.
