Raw images from Cassini were received on Earth shortly after the event, and a couple of processed images—a high-resolution image of the Earth and the Moon, and a small portion of the final wide-angle mosaic showing the Earth—were released to the public a few days following the July 19 imaging sequence.

The Large-aperture Synoptic Survey Telescope (LSST) is a 6.5-m-class optical telescope designed to survey the visible sky every week down to a much fainter level than that reached by existing surveys. It will catalog 90 percent of the near-Earth objects larger than 300 m and assess the threat they pose to life on Earth.
(For comparison purposes, satellite images on Google Mars are available to 1 meter. [21]) It can image in three color bands, 400–600 nm (blue–green or B–G), 550–850 nm and 800–1,000 nm (near infrared or NIR). [22] HiRISE incorporates a 0.5-meter primary mirror, the largest optical telescope ever sent beyond Earth's orbit.
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 James Webb Space Telescope has enabled astronomers to see things they can't explain. At least, not yet.In new research from Webb — the most powerful space observatory ever built ...
The hits just keep coming from the James Webb Space Telescope as NASA released a spectacular new image to mark the one-year anniversary of the start of its science mission. The shot is of the Rho ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
The first image from NASA's James Webb Space Telescope shows innumerable galaxies swirling around a central point, like the light thrown off from a disco ball.
