Many of the techniques now used to detect exoplanets — such as observations of their gravitational effect on the movements of their parent stars, or mini-eclipses that occur regularly as they pass in front of the stars as seen from Earth — aren't sensitive enough to detect the presence of an exomoon.

William Borucki, of the NASA Ames Research Center in Mountain View, California, has captured the astronomy prize for two achievements: conceiving the observational technique of transit photometry that raised the tantalizing prospect of sighting Earth - like planets orbiting other stars, and leading the 25 - year - long development of the Kepler mission, which in 2009 placed a telescope in space to make those observations.

The meeting presentations will focus on synergies among various approaches and provide recommendations on how to improve the use of earth observations, ground data and modeling techniques for the improved understanding of land use sources and sinks.

The measurements for the Earth's motions come from a variety of space - based measurements including satellites, like those in the Global Positioning System (GPS), the geodetic satellites that included records from NASA's older LAGEOS satellite, and observations of distant astronomical objects using a technique known as Very Long Baseline Interferometry.

See, the first thing to do is do determine what the temperature trend during the recent thermometer period (1850 — 2011) actually is, and what patterns or trends represent «data» in those trends (what the earth's temperature / climate really was during this period), and what represents random «noise» (day - to - day, year - to - random changes in the «weather» that do NOT represent «climate change»), and what represents experimental error in the plots (UHI increases in the temperatures, thermometer loss and loss of USSR data, «metadata» «M» (minus) records getting skipped that inflate winter temperatures, differences in sea records from different measuring techniques, sea records vice land records, extrapolated land records over hundreds of km, surface temperature errors from lousy stations and lousy maintenance of surface records and stations, false and malicious time - of - observation bias changes in the information.)
