[edit] Optical astronomy
The Subaru Telescope (left) and Keck Observatory (center) on Mauna Kea, both examples of an observatory that operates at near-infrared and visible wavelengths.
Optical astronomy from the ground is limited by (at least) two important things -- the cycle of day and night, and local weather conditions.

The Crab Nebula in the visible spectrum (photograph courtesy of the Anglo-Australian Observatory) shows two distinct features: a reddish web of filaments at the outer edges of the nebula and a bluish core.

As you can see, this is still lower than what is achievable for ground-based optical astronomy. Fortunately astronomers can also link up telescopes over longer baselines by recording the data with an accurate time base and correlating the data later.
Connie Walker, a Senior Science Education Specialist at the National Optical Astronomy Observatory in Tucson, Arizona, also hails the new resource.

The GONG homepage at the National Optical Astronomy Observatories is a must see. A concise fact sheet for GONG is available, as well as, information about helioseismology in general.
13. Compared with optical astronomy, what new problems arise when we wish to make observations in the high-energy domain? HINT
14. What is the main advantage of studying objects at different wavelengths of radiation? HINT ...
Because hydrogen is the most abundant element in the Universe, the Balmer lines are a common feature in optical astronomy and the red H line corresponding to the electron transition from the = 3 to the = 2 energy level gives the characteristic ...

"It was amazing how everything fell into place so neatly," says Steve Howell of the National Optical Astronomy Observatory in Tucson, Arizona. "All the features of this system are interlinked, so if you tinker with one, you have to change another.
These views, from a mosaic of ground- based (from the National Optical Astronomy Observatories) and Hubble images, show that the apparently smooth ring is actually made of myriad dense "comet-like" filaments that point away from the central star.
The idea of MMT was further advanced in the mid-1980s with the building of the New Technology National Telescope (NTNT) for the National Optical Astronomy Observatories, also located near Tucson.
Mark Dickinson, of the National Optical Astronomy Observatory, Tucson, AZ, principal investigator for the new observations, said "with these ultra-deep Spitzer images, we are easily seeing objects throughout time and space, ...

perception of radio astronomy conjures up images of astronomers in tight jeans wearing headphones to detect some weak signal buried in the galactic noise. If we apply a brief reality check, we find that radio astronomy is much like optical astronomy, ...
