Painted Asteroids in Sloan Digital Sky Survey

Painted Stone: Asteroids in the Sloan Digital Sky Survey from Alex Parker on Vimeo.

Over 100,000 asteroids and their colors, as seen by a single remarkable survey telescope.

This animation shows the orbital motions of over 100,000 of the asteroids observed by the Sloan Digital Sky Survey (SDSS), with colors illustrating the compositional diversity measured by the SDSS five-color camera. The relative sizes of each asteroid are also illustrated.

All main-belt asteroids and Trojan asteroids with orbits known to high precision are shown. The animation is rendered with a timestep of 3 days.

The compositional gradient of the asteroid belt is clearly visible, with green Vesta-family members in the inner belt fading through the blue C-class asteroids in the outer belt, and the deep red Trojan swarms beyond that.

Occasional diagonal slashes that appear in the animation are the SDSS survey beams; these appear because the animation is rendered at near the survey epoch.

The average orbital distances of Mercury, Venus, Earth, Mars, and Jupiter are illustrated with rings.

Colors represented with the same scheme as Parker et al. (2008):

Storm of Stars

Source: Wired From Wired: A storm of stars is brewing in the Trifid nebula, as seen in this view from NASA’s Wide-field Infrared Survey Explorer, or WISE. The stellar nursery, where baby stars are bursting into being, is the yellow-and-orange object dominating the picture. Yellow bars in the nebula appear to cut a cavity into…Read More

What’s Zero Gravity Feel Like?

Richard Branson’s Virgin Galactic has teamed up with the Zero G corporation to give anyone who has already purchased a $250,000 ticket a chance to get acclimated to the experience of zero gravity. Bloomberg’s Cory Johnson traveled down to Cape Canaveral to try it out and break down the business of weightlessness.
