Visible-light astronomy has existed as long as people have been looking up at the night sky, although it has since improved in its observational capabilities since the invention of the telescope, which is commonly credited to Hans Lippershey, a German-Dutch spectacle-maker, [1] although Galileo played a large role in the development and ...
The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
Hubble can also observe at ultraviolet wavelengths which do not penetrate the atmosphere. Each observatory was designed to push the state of technology in its region of the electromagnetic spectrum. Compton was much larger than any gamma-ray instruments flown on the previous HEAO missions, opening entirely new areas of observation.
Hubble Ultra-Deep Field image of a region of the observable universe (equivalent sky area size shown in bottom left corner), near the constellation Fornax. Each spot is a galaxy, consisting of billions of stars. The light from the smallest, most redshifted galaxies originated nearly 13.8 billion years ago.
COSMOS was launched in 2006 as the largest project pursued by the Hubble Space Telescope at the time, and still is the largest continuous area of sky covered for the purposes of mapping deep space in blank fields, 2.5 times the area of the moon on the sky and 17 times larger than the largest of the CANDELS regions. The COSMOS scientific ...
The northern lights made a rare appearance in the Massachusetts sky last night, treating sky-gazers to a colorful display that usually only appears further north.. The unusual showing was due to a ...
Some, however, were also placing blame on Elon Musk, who has previously lit up the desert night sky with a SpaceX rocket launch. But, a few others gave a more well-researched guess that the ...
There are over 200 full-sky images in spectral bands ranging from radio to gamma-rays There are also thousands of individual study images of various astronomical objects from space telescopes such as the Hubble Space Telescope, the Spitzer Space Telescope in infrared, the Chandra X-ray Observatory, COBE, WMAP, ROSAT, IRAS, GALEX as well as many ...
