... But light has many more secrets. For example, did you know that the light that we can see with our eyes is only one of many types of light? ... This is because when people are talking specifically about the type that we can see with our eyes, they usually only call it light when they should actually say visible light . While our eyes can only see visible light, special cameras can detect the other types. Things look very different when you photograph them in a different type of light. ...

... 2001 September 11 . Spiral Galaxy NGC 3310 Across the Visible . ... Explanation: The party is still going on in spiral galaxy NGC 3310. Roughly 100 million years ago, NGC 3310 likely collided with a smaller galaxy causing the large spiral galaxy to light up with a tremendous burst of star formation . ... NGC 3310 spans about 50,000 light years , lies about 50 million light years away, and is visible with a small telescope towards the constellation of Ursa Major . ... 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 gravitational lens effect of the red, foreground, elliptical galaxy visible near image center creates a cloverleaf image of the single distant quasar. ... NGC 1850: Gas Clouds and Star Clusters . ... Globular clusters only 40 millions of years old can still be found in the neighboring LMC galaxy, though, but perhaps none so unusual as NGC 1850. The Coma Cluster of Galaxies . ... Stars Without Galaxies . ... Galaxies are made up of stars, but are all stars found within galaxies? ... March . ...

Astronotes Armagh Planetarium's Stellar Blog! ... Colin Johnston . ... Our Galaxy . ... To locate it, look along the imaginary line between the two end stars on the leading edge of the PloughтАЩs blade (Merak and Dubhe) and Polaris (the North Star), the galaxy M82 (also known as the Cigar Galaxy) along with its companion M81, lies just off this line about a third of the way between the Plough and Polaris. €а€аAs usual, the supernova is far brighter than its home galaxy, appearing as an extra star. ...

... 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 ...

... STScI-PRC01-04 HUBBLE'S ULTRAVIOLET VIEWS OF NEARBY GALAXIES YIELD CLUES TO EARLY UNIVERSE Astronomers are using these three NASA Hubble Space Telescope images to help tackle the question of why distant galaxies have such odd shapes, appearing markedly different from the typical elliptical and spiral galaxies seen in the nearby universe. ... Light from these galaxies travels great distances (billions of light-years) to reach Earth. ... These stars emit mostly ultraviolet light. ...

... Bad Astronomy . Misconceptions . ... But what if they make Bad Astronomy there? ... But they aren't; what looks like a flat painting of stars on a canvas is actually a three-dimensional tapestry of stars at varying distances, the least of which is still tremendously far away. ... Look at the constellation of Orion, shown on the left as seen from the Earth. ... You cannot simply travel a thousand light years to the "opposite side" of Orion, look back, and see it backwards (as shown on the right)! ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

The Sun's corona . ... For instance, short "plumes" rising from the polar regions of the Sun look very much like field lines coming out of the end of a bar magnet, and they therefore suggest that the Sun, in addition to the intense fields of sunspots, also has a global magnetic field like the Earth's. Arches above the . Sun's surface . ... It is brightest near sunspots, whose arched field lines apparently hamper the outflow of solar wind which carries away energy and helps cool the corona. ...

This is the homepage of Andrew Fruchter, an astronomer on the staff of the Space Telescope Science Institute . ... Here you can look at an HST images of the optical counterparts of gamma-ray bursts and their host galaxies. ... Therefore, substantial information on the fine scale structure of objects can be obtained by offsetting the pointing of the telescope between exposures and then combining these "dithered" exposures into a single image. ...

Triple conjunction: After the Sun sets this afternoon, Monday 1 December 2008, look towards the south: J upiter, Venus and the crescent Moon are now in a beautiful conjunction that some astronomers are calling "the best sky show of the year". ...

... When the Voyager 2 spacecraft flew by the planet Uranus in January 1986, astronomers were treated to their first close-up glimpse of the satellites that orbit the seventh planet. ... But by far the most intriguing of those 15 satellites was a jigsaw-puzzle world called Miranda . ... How dark was it at Miranda? One of the Voyager scientists put it this way: Taking pictures in the Uranus system is like trying to do photography in a ballpark at night when the only light comes from a single candle. ...

... Your main research interests concern neutral hydrogen. ... That means that there must be enormous quantities of gas lying around, waiting for the chance to collapse under its own weight into lumps and form stars and galaxies. If we could actually observe this gas, as it moves around and assembles itself into lumps, we would be directly observing the process of galaxy formation. ... Optical astronomers seem to think that they can observe galaxy formation by taking optical images. ... In galaxies. ...

Dust and debris parade in an extremely misshapen ring around the young star, HD 15115. The disk, seen edge-on with NASA's Hubble Space Telescope, is the dense blue line extending from the star to the upper right and lower left of the image. The disk appears thicker at upper right than at lower left, evidence of its lopsided structure. Astronomers think the disk's needle-like look is caused by dust particles following a highly elliptical orbit around the star. ...
