In November 2010, the scientific journal Icarus published a paper by astrophysicists John Matese and Daniel Whitmire, who proposed the existence of a binary companion to our sun, larger than Jupiter, in the lengthy-hypothesized "Oort cloud" -- a faraway repository of small icy bodies at the edge of our solar system. The researchers use the identify "Tyche" for the hypothetical planet. Their paper argues that evidence for the world would have been recorded by the Broad-field Infrared Survey Explorer (Wise).
Clever is a NASA
mission, launched in December 2009, which scanned the complete celestial sky at four infrared
wavelengths about 1.5 times. It captured far more than 2.7 million photographs of objects in space, ranging from faraway galaxies to asteroids and comets reasonably close to Earth. Not too long ago, Sensible concluded an extended mission, enabling it to end a comprehensive scan of the asteroid belt, and two full scans of the more distant universe, in two infrared bands. So significantly, the mission's discoveries of previously mysterious objects incorporate an ultra-cold star or brown dwarf, 20 comets, 134 near-Earth objects (NEOs), and more than 33,000 asteroids in the primary belt in between Mars and Jupiter.
Adhering to its profitable survey, Sensible was put into hibernation in February 2011. Analysis of Sensible info carries on. A preliminary public release of the first fourteen weeks of information is planned for April 2011, and the final release of the total survey is prepared for March 2012.
Usually Asked Queries
Q: When could data from Wise
verify or rule out the existence of the hypothesized planet Tyche?
A: It is way too early to know whether Smart data confirms or policies out a huge object in the Oort cloud. Analysis over the subsequent few of years will be needed to establish if Sensible has actually detected such a entire world or not. The first 14 weeks of information, becoming released in April 2011, are unlikely to be enough. The total survey, scheduled for release in March 2012, must supply increased insight. When the Smart information are fully processed, released and analyzed, the Tyche
hypothesis that Matese and Whitmire propose will be tested.
Q: Is it a certainty that Clever would have observed such a planet if it exists?
A: It is most likely but not a foregone summary that Sensible could verify whether or not Tyche
