Callisto ("ka LIS toh") is the eighth of Jupiter 's known satellites and the second largest. ... Discovered by Galileo and Marius in 1610. ... Unlike Ganymede , Callisto seems to have little internal structure; however there are signs from recent Galileo data that the interior materials have settled partially, with the percentage of rock increasing toward the center. ... Callisto's surface is covered entirely with craters. ... Like Ganymede, Callisto's ancient craters have collapsed. ... Jupiter .. ...

Orbital intersection . ... Structure of Taurid stream . ... Meteoroid swarm and Taurid fireballs . ... The following four diagrams schematically show four different Taurid orbits and the orbits of Earth and Jupiter. ... The Taurid stream contains particles (small, solid grains) at different stages of their precession cycles. ... The study of when a meteor stream can produce a meteor shower is the study of when precession brings orbits to intersection with Earth, or e.g. with Mars . ...

IMPLEMENTATION OF THE MIR ORBITAL COMPLEX . MISSION PROGRAM . Since the launch of core module on February 20, 1986, till March, 23, 2001 Mir Orbital Complex (Mir OC) was in operational use on orbit under the Flight Test Program of the module-based permanently manned Mir station. A total of more than 100 launches of different spacecraft and modules (including the US Shuttle launches) were performed under the Mir Complex Mission Program. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Bad Astro Store . ... Site Info . ... It is from from Voyager 1 and shows a whopping big impact crater dominating the profile of the moon. Note that Mimas is about 400 kilometers across (about 250 miles). ... The wall around the crater is 5 kilometers high, and that central peak rises 6 kilometers above the surface (many impact craters have a large central peak which is caused by a pressure rebound from the impact). ... 2008 Phil Plait. ...

The H II complex N 44 in the Large Magellanic Cloud (LMC) provides an excellent site to perform a detailed study of star formation in a mild starburst, as it hosts three regions of star formation at different evolutionary stages, and it is not as complicated and confusing as the 30 Doradus giant H II region. We have obtained Spitzer Space Telescope observations and complementary ground-based 4 m uBVIJK observations of N 44 to identify candidate massive young stellar objects (YSOs). ...

... The spacecraft of Magion type have been selected as the subsatellites of the Interball project: Magion-4 (C2-X) for the Tail Probe and Magion-5 (C2-A) for the Auroral Probe. ... Magion-4 was produced in the Czech Republic in collaboratrion with Russia, Ukraine, Hungary, Austria and has onboard scientific instruments and sensors designed and built in Czech Republic, Russia, Poland, Hungary, Romania, Bulgaria and Slovak Republic. ...

... Sampling Descretization of a continuous-in-time signal into a finite number of samples Nyquist-Shannon Theorem: lossless for real sampling if t Lossless for complex sampling if t 1 1 2 Quantization Approximation of a range by a finite set of values Each value can be represented by a code for internal representation A reconstructed signal will differ from the original due to introduction of quantization ...

Ganymede . ... Ganymede Statistics . ... Hubble Finds Ozone on Jupiter's Moon Ganymede . ... Like Callisto , Ganymede is most likely composed of a rocky core with a water/ice mantle and a crust of rock and ice. ... Ganymede's mantle is most likely composed of ice and silicates, and its crust is probably a thick layer of water ice. ... Ganymede's surface is rich in water ice and Voyager and Galileo images show features which are evidence of geological and tectonic disruption of the surface in the past. ...

Microsymposium 34, MS058, 2001 ANOMALIES OF THE MOON'S THERMAL EMISSION IN THE IR SPECTRAL RANGE (10.5 - 12.5 micron). ... Sternberg State Astronomical Institute, Moscow, 119899, Russia, pugach@sai.msu.ru Summary: New satellite measurements of the lunar-surface radiation temperature were used to construct the spatial angular function of thermal radiation of the Moon in the infrared (10.5-12.5 micron) spectral range. ... These thermal anomalies are observed only in the limited range of phase angles. ...
