The extrasolar planets discovered to this time are believed to be giant gaseous planets similar to Jupiter and Saturn. ... This, together with the large masses of the extrasolar planets discovered to date, has led researchers to conclude that all the extrasolar worlds are giant gaseous planets similar to Jupiter and Saturn. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

I was wondering what conditions should be met to have the "darkest" sky .. ... Upon the above publication of the Southern Galactic hemisphere, TunГ Tezel started seeking opportunities to create the Northern counterpart image. ... So, the initial quest of having the darkest possible sky have delivered us these two all-sky images of the two galactic hemispheres as seen from Planet Earth. Zoomable and 'full-screenable' fisheye view of the "darkest sky" Southern Galactic Hemisphere image. ...

... This is a false color image of HR 4796A composed of visible and near-IR light (blue=STIS, green=1.71 micron, red=2.22 micron). It's red color is caused by dust grains that scatter light poorly in the visible and very efficiently in the near-IR. This images shows the debris disk around HD 61005, and a model of debris disk dust grains being blown by and interstellar wind. This work was a Goddard web feature (look there for a cool movie showing one of the models). ...

Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian disk. ... Raw versions of real-time processing pictures FDS 0000984 and FDS 0000986 were used (images 196 and 202). ...
