Radio Telescopes Salvage Titan Wind Data, Huygens Scientists Say - Space.com  By combining Doppler shift data from the Green Bank Telescope and other radio instruments, astronomers now know that while Titanís winds are relatively weak at the moonís surface, they reach nearly 270 miles (434 kilometer) an hour at an altitude of about 75 miles (120 kilometers). At an altitude of about 37 miles (59 kilometers), Huygens found highly variable winds that may be a region of vertical wind shear, mission scientists said. Ground-based observations of the Huygens probeís descent gave astronomers a glimpse at the north-south attributes of Titanís winds, but  the Cassini spacecraft failed to return data on the moonís east-west wind patterns.      
Scientists Announce Smallest Extra-Solar Planet Yet Discovered - SpaceDaily  Left:  Diagram showing rough comparison of the distance of PSR B1257+12's three inner most planets with our own.  Immersed in an extended cloud of ionized gas, the new planet orbits a rapidly spinning neutron star called a pulsar. The discovery, to be announced during a press conference at a meeting concerning planetary formation and detection in Aspen, Colorado, on 7 February, yields an astonishingly complete description of the pulsar planetary system and confirms that it is remarkably like a half-size version of our own solar system ó even though the star these planets orbit is quite different from our Sun. The small planet, about one-fifth of the mass of Pluto, may occupy the same outer-boundary position in its planetary system as Pluto does in our solar system.

Nano Probes Allow Researchers To See Tumors Through Flesh - SpaceDaily   Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only infrared light. "We have shown that the dispersion of thousands of brightly emissive multi-porphyrin fluorophores within the polymersome membrane can be used to optically image tissue structures deep below the skin Ė with the potential to go even deeper," said Michael J. Therien, a professor of chemistry at Penn. "It should also be possible to use an emissive polymersome vesicle to transport therapeutics directly to a tumor."
