... How to Identify that Light in the Sky . ... If so, and if you live near a city, the answer is typically an airplane, since planes are so numerous and so few stars and satellites are bright enough to be seen over the din of artificial city lights . If not, and if you live far from a city, that bright light is likely a planet such as Venus or Mars -- the former of which is constrained to appear near the horizon just before dawn or after dusk. ...

... Basic Observables: Zero-differenced phase and code ionosphere-free combinations of global GNSS network stations, corrected by P1-C1 satellite code biases (cc2noncc), daily observations with 30 seconds sampling rate Sites coordinates : IGb08 reference frame coordinates and velocities Displacements: solid tides, ocean loading, pole tide loading (IERS 2010) Geometric model : Receivers antennas eccentricities, absolute receiver and ...

... AstroAsciiData is a Python module to handle ASCII tables. ... The idea to develop this Python module emerged from the fact that ASCII tables continue to be one of the most popular and widely used data exchange formats in astronomy and probably science in general. ... To load this ASCII table, go into Python, load the AstroAsciiData module and read in the table with: . ... demo = asciidata.open('webexa.txt') . ... Users who only want to work with ASCII tables neeed no further python modules. ...

. This enhanced false-color image of Ida with its small satellite, Dactyl (right), is a vivid example of the effect of space weathering on asteroids. Blue regions on the asteroid tend to be associated with fresh, young craters where subsurface material recently has been exposed to space. Red regions on the surface correspond to old craters and flat surfaces that have not been disturbed in a very long time. NASA / JPL

VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...

... Tour Objects Tours can be created using objects from within the Autostar database or a user can enter in different objects (such as a newly discovered comet). ... Automatic Mode: As the user advances to each object, the title of the object appears on line 1 of the display while its descriptive text automatically starts scrolling across line 2. ...
