No need to have to be in orbit: a house telescope aboard a Boeing 747-SP allows scientists at the University of Bern to observe planets outside the solar program.
Many thanks to the SOFIA observatory (stratospheric observatory for infrared astronomy), Daniel Angerhausen's crew of University of Bern was ready to contemplate the earth GJ 1214b as it passed in front of its star. The 2.5-meter telescope and the affiliated instruments aboard the Boeing have proved their effectiveness in the useful check, the university declared Wednesday.
The SOFIA observatory flies at a greater altitude than the flights “explained Angerhausen, quoted in the statement. “Sofia is a house telescope that goes residence each individual early morning.” The observatory is a US-German task.
exoplanets in front of their stars, scientists can evaluate their sizing and duration of their rotation cycle.
Scientists can draw conclusions about the attributes of the atmosphere, such as its composition, temperature or strain. With terrestrial telescopes, stellar gentle nonetheless traverses the Earth's atmosphere and disturbs measurements, points out Angerhausen.
Tremendous-Earth or Mini-Neptune
initially details gathered by SOFIA have been published in the specialized journal “Astronomy & Astrophysics”. Despite an open ultimate end result, SOFIA offered new clues about the regularity of GJ 1214b. Scientists have not been ready to figure out no matter whether it is a pretty large rocky earth, a form of “Tremendous-Earth”, or relatively a “Mini-Neptune” of gas or ice.
Scientists are satisfied with the SOFIA check: sensitivity is higher adequate to perform in the exact league as the other observers of exoplanets like the Hubble or Spitzer house telescopes. (19459003)
