3. The completeness and reliability of threshold and false-discovery-rate source
The process of determining the number and characteristics of sources in astronomical images is so fundamental to a large range of astronomical problems that it is perhaps surprising that no standard procedure has ever been defined that has well understood properties with a high degree of statistical rigour on completeness and reliability. ... In this analysis we present results from testing such algorithms as implemented in the SExtractor, Selavy (Duchamp), and sfind tools on simulated data. ...

4. Andy Fruchter's Homepage
This is the homepage of Andrew Fruchter, an astronomer on the staff of the Space Telescope Science Institute . ... Here you can look at an HST images of the optical counterparts of gamma-ray bursts and their host galaxies. ... Therefore, substantial information on the fine scale structure of objects can be obtained by offsetting the pointing of the telescope between exposures and then combining these "dithered" exposures into a single image. ...

10. The Discovery of the Galilean Satellites
The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ...

12. ASP: An Ancient Universe - Changes in Stars
An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...

14. ASTEROID’S MOONS: DISCOVERY BY RADAR
... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...

... About meteorites . ... Meteoritic data . ... About laboratory . ... The lake is like a round mirror 200 meters in diameter, surrounded by a ring wall 350-400 meters across. ... The ring wall, especially well preserved along the southeast shore of the lake, the steep banks and the great depth, all indicated that at one time there had been a powerful explosion here. ... It is possible that the depth may have been 40 meters before but that the slumping of the banks was helping to decrease the depth. ...
