'Tenth planet' may be bigger than expected

Filed under
Sci/Tech

An observational error may have understated the size of the tenth planet - if "planet" is in fact what astronomers finally decide to call it.

The upper limit on the size of the object, temporarily called 2003 UB313, was earlier set at 3000 kilometres following the Spitzer Space Telescope's failure to spot any infrared source at its location. But as its discoverer Mike Brown notes on his website, the telescope was actually pointed at the wrong place, so the object could actually be bigger than that.

The Spitzer observations were made before the object was entered in public data bases, so Brown's group at Caltech, US, had to specify the positions of it and two other giant Kuiper Belt objects.

Spitzer was aimed correctly at two of them - but somewhere along the line an error crept in with the location of 2003 UB313. "The mistake was caught by one of the many extremely careful members of the Spitzer Science Center," Brown writes. Spitzer will check the right spot to see 2003 UB313 later in August.

The state of Linux gaming in the SteamOS era

For decades after Linux's early '90s debut, even the hardest of hardcore boosters for the open source operating system had to admit that it couldn't really compete in one important area of software: gaming. "Back in around 2010 you only had two choices for gaming on Linux," Che Dean, editor of Linux gaming news site Rootgamer recalls. "Play the few open source titles, Super Tux Kart and so on, or use WINE to play your Windows titles." Read more
