Environmental Protection Agencys National Decontamination Team. 19, 2008: Flying over storm-damaged refineries and chemical factories, a twin-engine plane carrying the ASPECT (Airborne Spectral Photometric Environmental Collection Technology) system has been on duty throughout the recent hurricanes that have swept the Florida and Gulf Coast areas.
The name ASPECT is an acronym for Airborne Spectral Photometric Environmental Collection Technology. Environmental Protection Agency project that can put chemical and radiological mapping tools in the air over an accident scene. More>Ī unique airborne emergency response tool, ASPECT is a Los Alamos/U.S. Her calculations correctly predicted the mass and location of both of the known satellite galaxies. With the help of NERSC systems, she successfully validated her method by analyzing the radio observations of the Whirlpool Galaxy, which has a visible satellite one-third of its size, and NGC 1512, which has a satellite one-hundredth its size. According to Chakrabarti, the dark satellite galaxies create disturbances in the cold atomic hydrogen gas at the edges of the spiral galaxy's disk, and these perturbations reveal the mass, distance and location of the satellite. When she applied this method to our own Milky Way galaxy, Chakrabarti discovered a faint satellite might be lurking on the opposite side of the galaxy from Earth, approximately 300,000 light-years from the galactic center. Using supercomputers at the National Energy Research Scientific Computing Center (NERSC), Sukanya Chakrabarti, an assistant professor of physics at Florida Atlantic University, developed a mathematical method to uncover these "dark" satellites. Scientists suspect that these faint satellite galaxies are primarily comprised of mysterious "dark matter" which makes up 85 percent of all matter in the universe and so far remains undetected.
While a few satellites are visible, like the Magellanic Clouds, many other galaxies are too dim to see. It should be recalled that a group of creative Japanese students from the University of Tokyo presented a robotic arm (already the third version), that overcomes a human in the popular game of Rock-paper-scissors.Astronomers predict that large spiral galaxies, like our Milky Way, have hundreds of satellite galaxies orbiting around them. “Maybe in the future, people can use this as decoration or a wearable,” Xingjie Ni, an assistant professor at Pennsylvania State University, who conceived the research idea and led the team, told Mashable.
Unlike previous attempts at an invisibility cloak, this design is scalable - able to cover larger objects without increasing the thickness of the cloak, and able to conceal objects that have sharp edges and peaks. “As long as the metasurface is designed correctly,” the study says, “both the container and the objects inside the container will become invisible.”

The study, modestly called “An ultrathin invisibility skin cloak for visible light,” was published in the journal Science.īecause the reflected intensity is close to that of a mirror, not only is the object undetectable, but so is the cloak. The so-called “metasurface” of the cloak was designed so that light hitting it “would be the same as that of light reflected from a flat mirror,” according to the team’s research.

But this cloak, at 80 nanometers thin, could be wrapped tightly around an object and leave it free from optical detection. While the cloak itself is 2D, it can cover a 3D object. The cloak is made up of tiny gold brick-like “nanoantennas” that reroute light waves away from the object, making it functionally invisible. It’s the first time scientists have been able to achieve this illusion using their technique. Researchers at University of California, Berkeley, made a small object disappear using an ultra-thin invisibility skin cloak - just 80 nanometers thin. Scientists have been able to create invisibility technology that made a small object disappear using an ultra-thin invisibility skin cloak, Mashable 17/9/15 Researchers at University of California, Berkeley created invisibility technology that can make things disappear just like in wizard’s world
