High - contrast observations with the Keck and Gemini telescopes have revealed three planets orbiting the star HR 8799, with projected separations of 24, 38, and 68 astronomical units. (science.sciencemag.org)
We resolved for the first time the scattered light from the nearly edge - on circumstellar disk around RY ~ Lup, at projected separations in the 100 \, au range. (arxiv.org)
Second, HDST must have exquisite starlight suppression that blocks out the starlight to 1 part in 10 billion for planet - star projected separations of about 35 milliarcseconds (equivalent to the width of a human thumb viewed from a distance of 130 km). (hdstvision.org)
