... Diagnostic exposures, science exposures and offset maps can be used to identify bad pixels and to confirm the presence of previously identified and up-linked bad pixels. The integration of the data over each exposure can be used to identify hot or flickering pixels (pixels with repeated occurrence in excess of the local Poisson probability distribution of X-ray events), for example running the SAS task .

Dear PALFA consortium members, Another smooth day of observing, with detections of J1928+1746 (PALFA#1), a much brighter re-detection of B2020+28, a few single-pulse candidates, and not much else to report from our quicklook. ... Update databsae with fill_observed.py Quicklook Notes: * Plot order bug: displays candidate 1, 10, 2, 3, .. Plot display bug: If the last candidate (#9 for now) is filtered out, then the single pulse plot is also filtered out. ... No other obvious quicklook candidates. ...

Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. ... Galileo scientists also are trying to determine the cause of the hole they found in Jupiter's magnetic field when the spacecraft was closest to Io. ...

Galileo Finds Giant Iron Core in Jupiter's Moon Io . Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. If so, it would be the first planetary moon known to have one. ... Space History Galileo . ...

... More than 200 microlensing events have been detected during the last ~4 years, most of them towards the galactic bulge. Since the line of sight towards the bulge passes through the disk and the bulge itself, the known stars towards the bulge play a dominant role as gravitational lenses. If these stars have planets around them, then the signature of the planets can be seen as sharp, extra peaks on the microlensing light curves. ... Status of some other similar efforts will be briefly discussed. ...

... 2005 April 5 . Light From A Distant Planet . Illustration Credit: R. Hurt ( SSC-Caltech ), JPL-Caltech , NASA . Explanation: Light emitted by a planet far beyond our Solar System has been identified for the first time. The planet, illustrated in the above drawing , had its light detected by comparing the brightness of only the parent star, when the planet was behind the star, to the light emitted when both the planet and its parent star were visible. ...
