Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2003 March 18 Coronal Holes on the Sun Credit: SOHO EIT Consortium ESA NASA Explanation: The ominous, dark shapes haunting the left side of the Sun are coronal holes low density regions extending above the surface where the solar magnetic field opens freely into interplanetary space . Studied extensively from space since the 1960s in ultraviolet and x-ray light , coronal holes are known to be the source of the high-speed solar wind , atoms and electrons which flow outward along the open magnetic field lines. During periods of low activity, coronal holes typically cover regions just above the Sun's poles. These coronal holes , however, have just moved into view near the Sun's equator, and particles escaping them have already caused notable aurora here on Earth. Coronal holes like this one may last for a few solar rotations before the magnetic fields shift and change configurations. Shown in false-color, this picture of the Sun on March 9 was made in extreme ultraviolet light by the EIT instrument on board the space-based SOHO observatory.

March Home Star Maps The Sky this Month My Astro Pics About Me ... Games Astronomy News Where are the other 'Earths' beyond the solar system? One of the most fascinating areas of astronomical research in recent years has been the search for other 'Earths' circling Sun-like stars far beyond our Solar System. In recent years nearly 100 planets have been discovered in orbits around other stars, but none of these 'exoplanets' remotely resembles the Earth. However, according to the latest computer simulations by Barrie Jones and Nick Sleep (The Open University), millions of Earthlike worlds could be scattered throughout the Galaxy, just waiting for telescopes to imp rove sufficiently for us to find them. NASA's Chandra X-ray Observatory has found two stars one too small, one too cold that reveal cracks in our understanding of the structure of matter. These discoveries open a new window on nuclear physics, offering a link between the vast cosmos and its tiniest constituents. Cosmic X-rays find evidence for new form of matter Chandra's observations of RX J1856.5-3754 and 3C58 suggest that the matter in these stars is even denser than

The Cookbook Camera is a CCD camera which I built following the directions supplied in "The CCD Camera Cookbook" by Richard Berry Veikko Kanto and John Munger. More information about this camera can be found at Richard Berry's Cookbook Camera Page Color images on this page have been produced using one of two methods. Most of the color images were obtained using cyan magenta , and yellow filters following a method created by Al Kelly Richard Berry Chuck Shaw , and Ed Grafton . This method, abbreviated as WCMY imaging, combines a series of exposures through each of the colored filters with a white (no-filter) image. The second method employed was LRGB, which combines a white (no-filter) luminance image with a series of exposures through

The Planet Pluto Pluto , which was discovered in 1930, is but a dot of light in even the largest Earth-based telescopes. Pluto is 2/3 the size of Earth's moon but 1,200 times farther away, which makes viewing surface detail as difficult as trying to read the printing on a golf ball located thirty-three miles away (more info) . The adjacent movie made from recent Hubble Space Telescope computer enhanced images (Ref) indicates that we are finally beginning to resolve some detail on the surface of this distant planet.

They heat up the interstellar medium, distribute heavy elements throughout the Galaxy, and accelerate cosmic rays . But just what is a supernova? And is there more than one type? Indeed, there seems to be two distinct types of supernovae those which occur for a single massive star and those which occur because of mass transfer in a binary system. As you will see, however, it is only what gets the process started toward the explosion which differs between the two types. Supernovae from Single, Massive Stars The Life Cycle of a Massive Star Stars which are 5 times or more massive than our Sun end their lives in a most spectacular way; they go supernova. A supernova explosion will occur when there is no longer enough fuel for the fusion process in the core of the star to create an outward pressure which combats the inward gravitational pull of the star's great mass. First, the star will swell into a red supergiant...at least on the outside. On the inside, the core yields to gravity and begins shrinking. As it shrinks, it grows hotter and denser. A new series of nuclear reactions begin to occur....temporarily halting the collapse of the core... but alas, it is only temporary. When the core contains essentially just iron, it has nothing left to fuse (because of iron's nuclear structure, it does not permit its atoms to fuse into heavier elements). Fusion in the core ceases.
