... Kepler is a mission designed to detect and characterize Earth-sized planets around solar-like stars. The sizes of the planets are determined from the decrease in light from a star that occurs during planetary transits, and the orbital period is determined from the repeatability of the transits. ... These goals are accomplished by continuously and simultaneously monitoring a single field of 140,000 stars for evidence of brightness changes caused by transits of Earth-sized or larger planets. ...

... Research . ... The major problem in HVC research is the unknown distance towards most of the HVCs. ... Thilker et al. (2004) used the Green Bank Telescope (GBT) to map an area of $7^{\circ} \times 7^{\circ}$ around M31 in H i . They discovered a population of HVCs located within a projected distance of about $50~\mathrm{kpc}$ from M31. ... 2004). ... The remaining HVCs around M31 are isolated in position and velocity and may represent primordial, dark-matter-dominated clouds. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

... Keywords: Proper Motions, Schmidt Plates, Astrometry, Guide Star Catalog, Palomar Sky Survey . In this paper we describe a program of determining proper motions from digitized scans of 1950's-era Palomar Sky Survey (POSS) Schmidt Plates and 1980's-era Palomar Oschin Schmidt `Quick V' plates that were taken for the Hubble Space Telescope ( HST ) Guide Star Catalogue. ... Arrows indicate the magnitude and direction of the proper motion for the stars. ...

Next: The Scenario Machine: Operational Up: Evolution of Magnetic Rotators Previous: Ejector-propeller hysteresis . ... The length of this segment is determined by the eccentricity. ... In this case no hysteresis occurs and transitions E -- P and the reverse take place in symmetrical points of the orbit. ... Here EP means a mixed state of the rotator at which it is in the ejector state during one part of the orbit, and in the propeller state during the rest of the orbital cycle. ...

Swift Launches . ... Credit Copyright: NASA Explanation: Where do gamma ray bursts occur? To help find out, NASA launched the Swift satellite on Saturday, as pictured above . What Swift is designed to do better than any previous satellite is to quickly locate these enigmatic explosions in both sky position and distance. Once a gamma ray burst (GRB) is located, Swift itself will rotate to face it head-on and determine its distance directly. ... NASA Official: Jay Norris. ...

Detection technique . We are using ISIS , the optimal image subtraction method developed by C. Alard & R.H. Lupton, to search for SNe in our images. ... The second image shows the same subtraction, but after the convolution of the best image with ISIS: . ... For this reason, we are suggested to search for nuclear SNe with NICMOS on HST, to exploit its stable PSF, sensitivity and angular resolution to detect from space nuclear obscured SNe which might have been missed by ground-based surveys. ...

. First Observer's Trailer Installation: June 17, 2002 . Unit R-8108 arrived around noon; driver determined to install the first trailer near the walkway instead of first placing the other trailer to the side of the storage uni. Note the damage in the upper right corner of the roof - missing shingles. Tight fit; the driver was confident there would be enough room to move in the other trailer. Note: the doors and windows are in the wrong location.

... We have determined the correlation coefficient between tree-ring index values and the sunspot cycle length for 69 tree-ring data sets from around the world of greater than 594 years duration. ...
