Summary

Description
English: This ALMA image of the young nearby star TW Hydrae has a resolution of 1 AU (Astronomical Unit, the distance from the Earth to the Sun in the Solar System). It reveals a gap in the disc at 1 AU, suggesting that a planet with a similar orbit to Earth is forming there.
Čeština: Snímek protoplanetárního disku kolem mladé hvězdy TW Hydrae pořízený pomocí radioteleskopu ALMA má rozlišení asi 1 au (také 1 AU podle starších pravidel, původně střední vzdálenost Slunce-Země, dnes přesně definována jako 149 597 870 700 m). Záběr odhaluje mezeru v disku ve vzdálenosti cca 1 au od hvězdy, což by mohlo naznačovat vznik Zemi podobné planety v této oblasti.
