M83 is one of the closest spiral galaxies to our own Milky Way Galaxy and from a distance of 15 million light-years, appears to be relatively normal. ... DIA Sunrise . ... Pictured is of one of the closest star forming regions, part of the Rho Ophiuchi cloud complex some 400 light-years distant near the southern edge of the pronounceable constellation Ophiuchus. ...

... Planets . ... Earth Satellites . ... Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

... An artificial comet holds secrets to Earths life . ... Astronomers recently discovered that Scholz's star passed close to the Sun 70,000 years ago. Wouldn't its gravity have sent Oort Cloud comets raining into the inner planets? ... COMETS | OORT CLOUD . Based on the number of long-period comets that enter the inner solar system, astronomers estimate there are probably trillions of them in the Oort Cloud.

... STScI-PRC95-45a CRUCIBLE OF CREATION: PANORAMIC HUBBLE MOSAIC ZOOMS IN ON MAELSTROM OF STAR BIRTH This spectacular color panorama of the center the Orion nebula is one of the largest pictures ever assembled from individual images taken with NASA's Hubble Space Telescope. ... Though this 2.5 light-years wide view is still a small portion of the entire nebula, it includes almost all of the light from the bright glowing clouds of gas and a star cluster associated with the nebula. ...

Trail encounter . ... Expected meteor rates . ... The Leonids are the debris of Comet 55P/Tempel-Tuttle. ... The Earth's passage right through the centre of trails is associated with the most spectacular meteor displays (studies show that, as well as how close to the centre of the trail you are, the strength of the display also depends on how far along a trail's length you are). ... The encounter with the 1932 trail will lead to enhanced meteor activity: a nice outburst, but below storm level. ...

... A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. ... These "tadpoles" (seen just below center) are regions of denser, cooler gas, and more slowly resist the erosive radiation from the hot stars. ...

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 . ...

... STScI-PRC00-10 "HUBBLE TAKES A CLOSE-UP VIEW OF A REFLECTION NEBULA IN ORION" Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a nebula in the constellation Orion. ... NGC 1999 is an example of a reflection nebula. ... The star is so young that it is still surrounded by a cloud of material left over from its formation, here seen as the NGC 1999 reflection nebula. ...

... The distances between stars are so immense that we can't use miles or kilometres to measure them, the numbers would become too large. For example, the closest star to our Solar System, is a whopping 38,000,000,000,000 kilometres away! And that's the closest star. ... And this cloud is inside one of the Milky Way s closest neighbours, a nearby galaxy called the Large Magellanic Cloud. ... The colourful clouds of gas and dust are filled with hot new-born stars which make these clouds glow. ...
