The Big Picture: Sauron in the stars


Nope, that isn't a grainy leaked photo from a new Lord of the Rings spin-off up above, it's actually an image of a space-dust ring surrounding nearby star HR 4796A. The star is part of the Centaurus constellation, and this picture was taken by the European Southern Observatory's (ESO) Very Large Telescope that's been recently outfitted with a SPHERE instrument. What's the SPHERE? According to the ESO, it's Spectro-Polarimetric High-contrast Exoplanet Research tool that has a main objective of studying extra-solar planets that orbit nearby stars. As Space notes, not only does this picture capture a very Eye-of-Sauron vibe overall, it's a showpiece for just how powerful the SPHERE tool is. Namely, it's able to kill enough of the glare to make the actual fiery ball of gas visible, something Space says is essential to discovering more and more celestial bodies.
