... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ... HISA Main ...

... To better understand this complex and chaotic process, astronomers used the Hubble Space Telescope to image in unprecedented detail the star forming region LH 95 in the nearby Large Magellanic Cloud galaxy. An Avalanche on Mars . ... What caused this sudden cloud of dust on Mars? An avalanche! The first avalanche imaged in progress on another planet was recorded last month on Mars by NASA's robotic Mars Reconnaissance Orbiter. ... Planets Align Over Australian Radio Telescope Array . ...

... January 24, 1998 . The Large Cloud Of Magellan (LMC) . ... These star clouds are small irregular galaxies , satellites of our larger Milky Way spiral galaxy . The Large Magellanic Cloud (LMC) pictured above is only about 180,000 light-years distant - the only known galaxy closer is the Sagittarius Dwarf . Both the LMC and the Small Magellanic Cloud (SMC) are joined to the Milky Way by a stream of cold hydrogen gas. ... Tomorrow's picture: The Small Cloud Of Magellan . ... About APOD > . ...

... Fig. ... One of these is a pink-coloured solar prominence, a tongue of incandescent hydrogen gas spewing out of the obstructed solar disc, visible at the 2 o'clock position. ... Such an eclipse was predicted to be visible from deep within the Asian continent on the 1st August 2008. ... A pink-coloured prominence was visible right from the onset (Fig. 1), while several streamers appeared to emanate from the obstructed solar disk throughout the event (Fig. ...

... STScI-PRC00-12 THE GLOWING EYE OF NGC 6751 Astronomers using NASA's Hubble Space Telescope have obtained images of the strikingly unusual planetary nebula, NGC 6751. Glowing in the constellation Aquila like a giant eye, the nebula is a cloud of gas ejected several thousand years ago from the hot star visible in its center. ... The nebula shows several remarkable and poorly understood features. ... Hajian and his team are scheduled to reobserve NGC 6751 with Hubble's WFPC2 in 2001. ...

... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...

... Operating at a wavelength of 10 ?m, it produces a 135њx135њ image with a resolution of 0.9њ. ... The clouds move from the west-southwest. ... At the same time as the IR images, visible light images were taken with an Apple Computer QuickTake electronic camera. ... At 1540 MDT, the large central cloud is visible in both images. At 1544 MDT, a distinctive cloud is apparent near the center in the visible image and right of center in the IR. The performance of the SDSS cloud scanner is excellent. ...

... Happy Birthday to the Very Large Telescope! To celebrate, the telescope has been used to take this space photograph of a party in space. ... What this picture actually shows is a spectacular cloud of gas and dust that astronomers call a stellar nursery. That s because deep inside this pretty pink cloud, new stars are flaring into life. ... Silhouetted against the glowing pink gas are clouds which look like balloons : even thicker clumps of dust, known as Thackery's globules. ...
