    Star Cluster R136 Bursts Out
    In the center of star-forming region 30 Doradus lies a huge cluster of the largest, hottest, most massive stars known. These stars, known collectively as star cluster R136, were captured above in visible light by the Wide Field Camera peering through the refurbished Hubble Space Telescope. Gas and dust clouds in 30 Doradus, also known as the Tarantula Nebula, have been sculpted into elongated shapes by powerful winds and ultraviolet radiation from these hot cluster stars. The 30 Doradus Nebula lies within a neighboring galaxy known as the Large Magellanic Cloud and is located a mere 170,000 light-years away.

    Octopus-Inspired Camo Changes Color In Light

    Researchers have taken a tip from the ocean’s masters of disguise to develop a new active camouflage system. 

    An international team of scientists coupled heat-sensitive dye with a distributed grid of photoreceptors to make a flexible material that changes color based on the light that falls on it. When any of the system’s cells is heated above 117 degrees Fahrenheit by a silicon diode underneath, the dye turns from black to clear.

    Like the cephalopods that inspired the work, the camo system can respond to changes in light within two seconds using 

    The concepts provide realistic routes to thin sheets that can be conformally wrapped onto solid objects to modulate their visual appearance, with potential relevance to consumer, industrial, and military applications," the authors write in a report on their work published today in the journal PNAS.
