NASA exploring Pluto
Cristina From Hours worked on spectrographs used to photograph the dwarf planet
TREVISO From Treviso thanks to Pluto spectrograph that she invented. It is the journey across the sky that Cristina Dalle Ore, astronomer Treviso transplanted in Cupertino, is doing with his team working at NASA in California. His role, as she called it in an interview with the journal Wired, is to “detective-archaeologist who studies the hyperspectral images.” Images that, thanks to the spectrograph launched into orbit with a probe, have allowed for the first time of photographing Pluto. “These are images in which each pixel has a spectrum, namely the representation of the reflected light 256 of different wavelengths from Pluto covered by the pixel. Imagine a rainbow with 256 colors instead of the usual 6 – explained the scientist to the science magazine Wired -.
The intensity of the color is like the fingerprint surface and from that we can trace the composition and indirectly to the history of the surface. They are part of a small group of scientists (three) and we each apply different analytical techniques that we compare to make sure the results are accurate. ” An important step for the project to which the works and Treviso which experienced the most significant moment on Monday when Pluto came the first images: “I was not in the skin by the desire to analyze and understand their meaning. At the same time was one of the days more ‘exciting of my career. ” Cristina Dalle Ore is enthusiastic about her work and a mission, he continued to Wired: “It pushes the boundaries of our species on the edge of the solar system and will be an inspiration for the younger generation to continue to expand the horizon of our knowledge to new destinations more and more distant. ”
