NASA’s WISE Colors in Unknowns On Jupiter Asteroids |
Scientists using data from NASA’s Wide-field Infrared Survey Explorer, or WISE, have uncovered new clues in the ongoing mystery of the Jovian Trojans — asteroids that orbit the sun on the same path as Jupiter. Like racehorses, the asteroids travel in packs, with one group leading the way in front of the gas giant, and a second group trailing behind.
The observations are the first to get a detailed look at the Trojans’ colors: both the leading and trailing packs are made up of predominantly dark, reddish rocks with a matte, non-reflecting surface. What’s more, the data verify the previous suspicion that the leading pack of Trojans outnumbers the trailing bunch.
The new results offer clues in the puzzle of the asteroids’ origins. Where did the Trojans come from? What are they made of? WISE has shown that the two packs of rocks are strikingly similar and do not harbor any “out-of-towners,” or interlopers, from other parts of the solar system. The Trojans do not resemble the asteroids from the main belt between Mars and Jupiter, nor the Kuiper belt family of objects from the icier, outer regions near Pluto.
“Jupiter and Saturn are in calm, stable orbits today, but in their past, they rumbled around and disrupted any asteroids that were in orbit with these planets,” said Tommy Grav, a WISE scientist from the Planetary Science Institute in Tucson, Ariz. “Later, Jupiter re-captured the Trojan asteroids, but we don’t know where they came from. Our results suggest they may have been captured locally. If so, that’s exciting because it means these asteroids could be made of primordial material from this particular part of the solar system, something we don’t know much about.” Grav is a member of the NEOWISE team, the asteroid-hunting portion of the WISE mission. continue reading
Doug Perrine captured these stunning photographs in the Maldives. The particular location (Vaadhoo Island) has a concentrated population of bioluminescent phytoplankton. Bioluminescence is a natural chemical reaction which occurs when a micro-organism in the water reacts with oxygen. When washed ashore by the tides, the phytoplankton’s chemical energy is turned into light energy, illuminating the waves.

Before becoming an illustrator, he was, by turns : an astrophysician, an international snooker player, a hypnotist and an esperanto teacher. “I hope i can someday have enough free time to devote myself to my real passion: time travel.” (cf. artist’s bio) You can find more Julien’s work on his website and what inspire him on his Tumblr.
