The Space Telescope Revolution Dust ring Location of Fomalhaut Scattered starlight Fomalhaut b Coronagraph mask Above left: A dusty ring encircles the star Fomalhaut, potentially sculpted by a growing planet (circled). Above: A view toward the galactic center, down to magnitude 30. Hubble monitored tens of thousands of stars for periodic dips in brightness, and astronomers identified potential hot Jupiters around several (circled). Far left: These two cocoons in the Orion Nebula enshroud protoplanetary disks of dust and gas around embryonic stars. The disk in the lower image appears clearly as a green oval. Near left: As they form, protostars eject jets along their poles, forming glowing patches called Herbig-Haro objects. Two pairs of jets appear in this image of the Carina Nebula: one at the very top, and the other at the top of the second-tallest "peak." Bottom: The iconic Pillars of Creation in the Eagle Nebula, in infrared (left) and visible wavelengths. The infrared image cuts through all but the densest dusty gas and confirms that the pillars are gas that's hiding in the "shadow" of dense clouds at the pillars' tops. Those clouds shield the gas below from destructive ultraviolet radiation and stellar winds raining down from stars above. 22 June 2015 sky & telescope FOMALHAUT: NASA / ESA / P. KALAS AND J.
