A likely reason for this is that the older stars in the center are actually triggering the formation of the younger edge stars. The triggered star formation occurs when hot outflowing gas compresses cooler gas into knots dense enough to gravitationally contract into stars. ...

... The Colors of IC 1795 . ... Credit: Don Goldman Explanation: This colorful cosmic portrait features glowing gas and dark dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia. The nebula's colors were created by adopting the Hubble false-color palette for mapping narrow emission from oxygen, hydrogen, and sulfur atoms to blue, green and red colors, and further blending the data with images of the region recorded through broadband filters. ...

home publications > mercury . ... Rings of Creation . ... 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. ...

It is especially hard to explain this process of star birth in some spiral galaxies. ... Targets include both star clusters and galaxies, and star formation rates seen range from the starburst galaxy M82 (the Cigar Galaxy) which is creating about ten new stars in its core alone every year to the much less fecund star producer NGC 2841. ...

Henize 206 is a region of star formation in the Large Magellanic Cloud of the approximate scale of the Orion belt and sword. Our Spitzer Space Telescope infrared images and Cerro Tololo Inter-American Observatory (CTIO) optical images show that the region is experiencing very energetic star formation. ... A few percent of the total flux from this brightest region in Henize 206 emanates from infrared peaks of subparsec scale. ...

... This is combined emission from all the gas clouds circling the black hole, between 0.1 and 10 light years out. ... These are the expanding clouds of gas left behind when a massive star comes to the end of its life and explodes, producing a supernova. ...

... To move toward open analysis software, we plan to make the PROS regions subsystem available from processes outside of IRAF. We also plan to make the region descriptor parsing system available for purposes beyond the creation of masks, such as an interface to an image display program, accepting a region descriptor and generating commands to display the region on an image. ... Anticipating two kinds of new requirements, we reconsidered the design of the PROS region descriptor processing subsystem. ...

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. ...

Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...

... If requested ( runbackground =Y), the task creates a background lightcurve, as well as a background spectrum for the imaging modes (FF, eFF, LW, SW) using background masks. ... The background masks are created by task badpixfind using threshold parameters, appropriate for the detection of real X-ray sources. ... As the GTIs strongly depend on the intended science this screening is not performed and only background masks, the lightcurve, and a GTI file are created by epchain . ...

. This new infrared view of the star forming region the Lagoon Nebula (M8) was captured by the VISTA telescope at ESOтАЩs Paranal Observatory in Chile. This color picture was created from images taken through J, H, and Ks near-infrared filters, which were acquired as part of a huge survey of the central parts of the Milky Way. The field of view is about 34 by 15 arcminutes. ESO/VVV

... The forcing by the solar wind is able to modify this field, creating a cavity called the magnetosphere. ... The outer boundary of the magnetosphere is called the magnetopause . In front of the dayside magnetopause another boundary called the bow shock is formed because the solar wind is supersonic. ... Solar wind and the magnetic field it carries along ( IMF ) modify the form of the magnetosphere, by pushing it in in the dayside and creating a long magnetotail in the nightside. ...
