- "Flying Telescope" begins 4th round of flights to map galaxies, planets
- The 1 year SOFIA project is conducted by NASA, German Aerospace Centre
- Infrared energy used to map celestial objects invisible in normal light
This operational period, known as "Cycle 4", is a one-year-long observing period in which the Stratospheric Observatory for Infrared Astronomy (SOFIA) is scheduled for 106 flights between now and the end of January 2017.
"The Cycle 4 programme will make more than 550 hours of observations," said Pamela Marcum, NASA's SOFIA project scientist in a statement.
"We'll be studying objects including planets, moons, asteroids and comets in our solar system; star and planet formation; extrasolar planets and the evolution of planetary systems; the interstellar medium and interstellar chemistry; and nearby normal and active galaxies," Marcum explained.
SOFIA's instruments observe infrared energy - one part of the electromagnetic spectrum which includes visible light, x-rays, radio waves and others.
Many objects in space, for example newborn stars, emit almost all their energy at infrared wavelengths and are undetectable when observed in ordinary visible light.
In other cases, clouds of gas and dust in space block visible light objects but allow infrared energy to reach Earth.
In both situations, the celestial objects of interest can only be studied using infrared facilities like SOFIA.
"During the February third flight, the target objects ranged from a young planetary system around the naked-eye star Vega, only 25 light years from us, to an infant star 1,500 light years away in the Orion star forming region," noted Erick Young, SOFIA's science mission operations director.
"We also observed a supermassive black hole hidden behind dense dust clouds in the center of a galaxy 170 million light years away," he added.
Later in "Cycle 4", the SOFIA observatory is scheduled to deploy to the Southern Hemisphere for seven weeks in June and July 2016, with 24 science flights planned from a base at Christchurch, New Zealand.
There, scientists will have the opportunity to observe areas of interest such as the Galactic Center and other parts of the Milky Way that are not visible or difficult to observe from the Northern Hemisphere.
SOFIA is a joint project of NASA and the German Aerospace Center (DLR). NASA's Ames Research Center in Moffett Field, California, manages the SOFIA programme.
