... Credit Copyright: Stan Honda Explanation: Beautiful, luminous decorations on this pinyon pine tree are actually bright stars in the constellation Scorpius and the faint glow of the central Milky Way. Captured in June from the north rim of the Grand Canyon of planet Earth, the shallow, close focus image has rendered pine needles on the tree branch sharp, but blurred the distant stars, their light smeared into remarkably colorful disks. Of course, temperature determines the color of a star . ...

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. ...

Discover the cosmos! ... December 6, 1999 . M83: The Southern Pinwheel Galaxy from VLT . ... Explanation: M83 is one of the closest and brightest spiral galaxies on the sky. Visible with binoculars in the constellation of Hydra , majestic spiral arms have prompted its nickname as the Southern Pinwheel. Although discovered 250 years ago, only in this century was it appreciated that M83 was not a gas cloud but a barred spiral galaxy much like our own Milky Way Galaxy . ... About APOD > . ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

The WFPC2 UBVRI system is fairly close as regards effective wavelengths to the Johnson UBVRI system, but cross-calibration is necessary to convert to Johnson magnitudes. ... For hotter stars, the transformation is quite linear.  Figure 8.2: F439W-F555W against Johnson B-V. The residuals from the best linear fit are quite similar to those that apply if F569W (instead of the preferred F555W) is chosen for a WFPC2 passband. ... This particular color combination is widely used.  ...

... First of all, you can obtain a map of the final coordinates of your objects and guide stars by using the command: PLOT/OPTOPUS [table] [label] [EW_flag] , . where [table] is the table output by REFRACTION/OPTOPUS . ... In order to avoid object misidentifications at a later stage, and for a cross identification between object identifiers and hole numbers, it is recommended to bring a printout of the table output created by the command REFRACTION/OPTOPUS to the telescope. ...

. Breathtaking! Moraine Lake in all its glory! . I really tried to capture it all in my camera. It is absolutely impossible. First, the place is gigantic. Second, not matter how good the photos are, nothing comes close to actually being there! . One of the reasons why it is so much better to just be there is that we just keep getting different perspectives when we hike along the shore of this lake. The blue color of the lake is striking, even when hiking among the trees. We are now looking back...
