... The first step is to open and inspect the camera body. ... Notice that there are snap locks on both sides of the camera body, one of which should already be open since it contained the film removed by the developer. To open the camera body, peel back some of the yellow sticker identifying the camera as KODAK on the top and bottom of the camera and unsnap the plastic pieces. ... You should now have four pieces: the front cover, back cover, middle (main camera with lens), and a cylindrical spool. ...

. Comment on J1640+1220 . Augusto, Wilkinson & Browne (1998) show a 5 GHz MERLIN image and describe the source as a core-jet: their jet component is at PA=-50 . This, and our image, imply a gently curved jet from mas to 100 mas scale. The mas-scale structure is similar in the 8.4 GHz image from the VLBA Calibrators database. VLBApls home page .

... For the first balloon flight of the Nuclear Compton Telescope (NCT) we have simultaneously reduced lowenergy background and enabled hard X-ray imaging by enshrouding the top of the instrument in a tin shield (bottom had BGO shielding), with part of the shield having strategically placed holes -- a 10% open coded aperture mask working up to 80 keV in conjunction with the finely pixellated double-sided Ge strip detectors. ...

The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...

. This illustration shows the discovery that the outer Milky Way is a really a mixture of two distinct components rotating in opposite directions. The inner component of the Galaxy's halo spins clockwise with the galaxy's rotation at about 50,000 miles per hour. The outer component rotates counterclockwise to the galaxy at 100,000 miles per hour. SDSS-II, Masashi Chiba, Tohoku University, Japan
