Paris, Nov 20 : The Akari infrared surveyor, a Japanese Aerospace Exploration Agency mission with ESA (European Space Agency) participation, is uncovering a number of secrets of the cold and dusty Universe.
For example, Akari observations of Betelgeuse, a bright red supergiant star located in the constellation Orion about 200 light-years from Earth, show the star making a big splash by creating a bow shock as it crosses the interstellar medium.
