... Hubble View: Jupiter Impact . ... This sprawling dark marking is Jupiter's latest impact scar, a debris plume created as a small asteroid or comet disintegrated after plunging into the gas giant's atmosphere. Located in Jupiter's south polar region, the new feature was discovered by Australian amateur astronomer Anthony Wesley on July 19. ... The July 22nd total solar eclipse was the longest of the 21st century. ... Seeing the corona first-hand during a total solar eclipse is best. ... July . ...

... Scientists of Samara State Aerospace University (SSAU) have created an unique mobile platform for the production of training and gaming simulators. ... Such mobile platforms also known as the Stewart platforms became widespread in the world primarily as simulators for training of highly-qualified military pilots and drivers. ... For example, the Rocket and Space Centre Progress is going to test level sensors for residual fuel in the fuel tanks of the rocket carrier on this mobile platform. ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

What will happen when the fragments hit Jupiter? ... All the fragments will enter Jupiter's atmosphere at an angle of 42 degrees from the vertical and impact near a latitude of 44 degrees south, but on the back side of the planet as seen from Earth (about 10 degrees in longitude behind the edge of Jupiter, as seen from Earth). ... Any body moving through an atmosphere is slowed by atmospheric drag, by having to push the molecules of that atmosphere out of the way. ...

The above process keeps the # of protons and the # of neutrons in the early Universe constant. This is extremely important and will result in a testable prediction later. Remember, a free neutron (one that is not bound in an atomic nucleus) will decay into a proton + electron (+ anti-neutrino) in about 900 seconds. ... During this epoch, the proton-to-neutron ratio is 1.0 . ... The Universe consists of protons, neutrons and electrons plus a photon background and a neutrino background. ...

BACKGROUND . ... Electron bombarded silicon (EBS) gain makes the CCD interesting for keV electron detection. Ionizing particles absorbed in silicon create electron-hole pairs at the average rate of one per 3.64 eV incident energy. ... The variance in the number of electron-hole pairs created is given by the Fano factor for silicon (.1-.2) times the number of pairs created. When we use a CCD as a detector of ionizing particles, we would like to collect all of the electrons created. ...

. To remove a directory that is a symbolic link that points to another directory use the command: rm directory_name . Notice that the directory does not need to be empty and you do not have to use the rmdir command. You are not really removing a directory, just a named symbolic link that points to the "real" directory.

... In the presence of only uniform magnetic field B , the motion of a charged particle can be described with gyration about the guiding center and motion along the field line. ... In the precence of both magnetic and electric fields, the equation of motion for charged particle (mass m, charge q) is m d v /dt = q ( E + v x B ). ... Because v is independent of the mass and sign of the charge, it is the same for negatively and positively charged particles, and does not create electric current. ...
