The Wide-field Infrared Survey Explorer (WISE) space telescope has completed an all-sky infrared survey that includes areas where Whitmire and Matese anticipate that Tyche may be found. [7] On March 14, 2012, the first-pass all-sky survey catalog of the WISE mission was released. [21]
Hyperion, a large distant 10th planet theorized in 2000 to have had an effect on Kuiper Belt formation. [4] Tyche, a hypothetical planet in the Oort Cloud supposedly responsible for producing the statistical excess in long period comets in a band. [5] Results from the WISE telescope survey in 2014 have ruled it out. [6] [7] [8]
This list of exoplanets discovered in 2025 is a list of confirmed exoplanets that were first reported in 2025. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
More than 100 of the new planets are 1.2 Earth masses or smaller and are 'almost certainly rocky in nature.' NASA just discovered 1,284 new planets -- here's how many could potentially support ...
Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find ...
Harrington died in January 1993, without having found Planet X. [53] Six months before, E. Myles Standish had used data from Voyager 2's 1989 flyby of Neptune, which had revised the planet's total mass downward by 0.5%—an amount comparable to the mass of Mars [53] —to recalculate its gravitational effect on Uranus. [54]
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
