Astronomy Picture of the Day . Bright Points on the Quiet Sun . ... Explanation: Up close, the solar surface is a striking patch work of granules in this very high resolution picture of the quiet Sun . Caused by convection, the granules are hot, rising columns of plasma edged by dark lanes of cooler, descending plasma. ... Constantly present on the solar surface, the bright points do not seem to be related to sunspots that come and go with the magnetic solar cycle . ... Hole in the Sun . ...

IBIS Data Analysis . ... IBIS . ... Flat Fielding - Introduction . The images obtained by IBIS will have intensity variations across the field of view that are not due to the solar image, but rather caused by instrumental effects that alter the observed intensity in each point of the field of view. ... IBIS Flat Fielding Techniques . ... Therefore, it is desirable to obtain the flat field measurements center on a point along the equator near the heliographic center of the solar disk. ...

... Note that invert supports multi-frequency synthesis, Stokes and spectral imaging. options=mosaic : The most important thing to remember is to invoke invert 's mosaic mode! ... This is because the full field of the each individual pointing is potentially filled with emission. vis : When mosaicing, invert handles input datasets which contain multiple pointing centres. imsize : In mosaic mode, this is interpreted as the image size, in pixels, of each subfield. ...

... Bad Astronomy . ... Bad Astronomy : The seasons are caused by the change in the distance of the Earth to the Sun. ... The change in distance of the Earth to the Sun is a very minor player. ... Well, not completely wrong; certainly the Earth's distance from the Sun has something to do with the temperature, but it is a relatively minor effect. ... Basically, the temperature depends only weakly on distance changes; the temperature goes as the inverse square root of the distance of the planet to the Sun...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... We study the magnetic field structure and evolution for 26 X-ray brightening events in coronal holes and quiet Sun regions, including bright points and jets. We found that all brightening events are associated with bipolar regions and caused by magnetic flux emergence followed by cancellation. ... Comparing coronal holes and the quiet Sun, we do not find differences in their corresponding magnetic field behavior. ...

This image displays a portion of the South Pole Telescope survey of the cosmic microwave background (CMB) - the radiant light left over from the Big Bang. ... The variations in the image are minute fluctuations in the intensity of the CMB. The fluctuations are caused by differences in the distribution of matter in the early universe at a time only 400,000 years after the Big Bang. The image is effectively a "baby picture" of the universe. ...
