A star system with a cool methane-rich T-dwarf star and a dying white dwarf stellar remnant in orbit around each other gives scientists the first good handle on T-dwarfs’ mass and age.
...
The methane dwarf was identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) as part of a project to identify the coolest objects in the galaxy. The Gemini North Telescope in Hawaii measured the temperature and spectrum.

Jupiter's missing stripe returns
November 24, 2010 - USA Today
A brown stripe on Jupiter, the king of planets, has returned after a springtime fade, astronomers reported Wednesday.
Called the South Equatorial Belt (SEB), the atmospheric band south of Jupiter's equator had turned white, earlier this year. In November, however, Filipino amateur astronomer, Christopher Go of Cebu City, observed a bright spot in the unusually whitened belt, according to a University of California, Berkeley, statement. Observations from large telescopes in Hawaii, suggest the stripe has returned.

NASA: Stripe that disappeared on Jupiter coming back
November 25, 2010 - CNN (blog)
One of Jupiter's stripes that "disappeared" last spring is reappearing – and the disappearance was apparently an illusion created by Jupiter's atmosphere, NASA scientists said.
Scientists noticed earlier this year that the longstanding dark-brown stripe, called the South Equatorial Belt, had turned white, essentially disappearing. Researchers with NASA's Infrared Telescope Facility, the W.M. Keck Observatory and the Gemini Observatory telescope began studying the phenomenon and found the answer likely lies in a cloud deck made up of white ammonia ice that basically obscured the ring.
