... If the parameter withinputlist is set to ``true'', the reconstruction and/or background image will be created using source parameters from an input source list. ... Use parameters makerecon and savebkgrnd to specify which of the output images you want to create. Only sources originally detected at scales up to maxscale will be used for to calculate the images. The value of maxscale will also control the scale of the kernel used to filter the background image. ...

In 1755, Immanuel Kant had the remarkable insight that stars and planetary systems form by the gravitational collapse and rotational flattening of interstellar clouds. Later in the 18th century, Marquis Pierre Simon de Laplace refined Kant s idea by suggesting that planets condensed from rings produced at the edge of a contracting disk while the Sun formed at the center a picture thereafter known as the Nebular Hypothesis. ...

Isaak Newton (1642 - 1727). ... During 1665 - 1667 Newton made his three main discoveries: the method of fluxings and quadratures (differential and integral calculus, explanation of the light nature and the law of gravitation). ... In 1668 Newton built the first reflecting telescope. The big lens telescope gave indistinct image with painted edges. ... The scientist considered this problem indisolved and suggested a mean against chromatic aberration: a mirror must be used instead of objective lens. ...

The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... That produces an extra resistance to the flow of current. ...

... Time service of RATAN-600 outputs sideral seconds and impulses of minutes with time codes for feed-cabines. These signals are coincided with local sideral time, recalculated from coordinate time UTC, using of sideral time program (stm) having accuracy of 0.0001s. DeltaUTC can be received from Time service or from Astronomical Annuals. The program stm calculates mean sideral time on any date with high accuracy (usage: stm hh [dd/mm/yy] ). ...

... Submitted by Robert Halstead on 10/12/2010 20:35:42 . Stacked image to get longer exposure . This image was created by stacking nine 60-second exposures that were made over the course of a 30-minute period. The comet is moving through the sky quickly enough that aligning the comet in all the images causes the star images to spread out in a line. ...

The Very Large Telescope Interferometer (VLTI) at ESO s Paranal Observatory in Chile has obtained the sharpest view ever of the dusty disk around the close pair of aging stars IRAS 08544-4431. For the first time, such disks can be compared to the disks around young stars and they look surprisingly similar. ... The inset shows the VLTI reconstructed image, with the brighter central star removed. The background view shows the surroundings of this star in the constellation Vela the Sails. ...

Next: Binary Radiopulsars with Black Up: Black Holes in Binaries Previous: Black Holes in Binaries . Two different types of stellar BH formation exist: (1) direct core collapse   of a massive star and (2) AIC of a NS. A BH of the first type presumably will have a mass comparable to that of the collapsing star and can be born both from a single star and in a binary system. ...
