The lucky imaging system averages the images taken during the excellent periods to produce a final image with much higher resolution than is possible with a conventional long-exposure AO camera. This technique is applicable to getting very high resolution images of only relatively small astronomical objects, up to 10 arcseconds in diameter, as ...
An astronomical interferometer or telescope array is a set of separate telescopes, mirror segments, or radio telescope antennas that work together as a single telescope to provide higher resolution images of astronomical objects such as stars, nebulas and galaxies by means of interferometry.
Typical DSO survey in Celestia. Celestia versions 1.6.3 and under display the Hipparcos Catalogue (HIP) of 118,322 stars and a compiled catalogue of galaxies, while version 1.7.0 includes stars from the Tycho-2 Catalogue alongside the Hipparcos stars, with some data from Gaia, increasing the star count to over 2 million.

The images, taken on March 22, 2023, and released Wednesday, showcase different dynamic aspects of the sun, including the movements of its magnetic field and the glow of the ultrahot solar corona ...
The images, obtained in March 2023 by the ESA's Solar Orbiter, represent what the agency says are the highest-resolution views of the sun's surface, known as the photosphere, to date.
The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.
During the four hours it took Cassini to image the entire 647,808 kilometres (402,529 mi)-wide scene, the spacecraft captured a total of 323 images, 141 of which were used in the mosaic. [6] NASA revealed that this imaging marked the first time four planets – Saturn, Earth, Mars, and Venus – had been captured at once in visible light by the ...
On 1 September 1979, Pioneer 11 passed within 13,000 mi (21,000 km) of the planet's cloud tops at a speed of 71,000 mph (114,000 km/h). An animation of a sequence of images taken by the Voyager 1 probe of the planet Jupiter. One frame was taken every Jupiter day, about 10 hours, from 1 June 1979 to 2 March 1979, giving 66 frames in all. [3]
