Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time. [3] [4] SMACS 0723 is a galaxy cluster visible from Earth's Southern Hemisphere, [5] and has often been examined by Hubble and other telescopes in search of ...
In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images of this small celestial object and its ...
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations.
It was found by Peter Berrett, who participates in the NASA funded Sungrazer project. [81] PSP-001 was discovered in images from 29 May 2022, part of the spacecraft's 12th approach to the Sun. Since this discovery, a further 19 sungrazer comets have been discovered in the images taken by the Parker Solar Probe, including two non-group comets.
Near-Earth object detection technology began to improve around 1998, so objects being detected as of 2004 could have been missed only a decade earlier due to a lack of dedicated near-Earth astronomical surveys. As sky surveys improve, smaller and smaller asteroids are regularly being discovered.
The Orion spacecraft's record-setting distance from Earth made for stunning photography, apparently. NASA has shared a photo taken by the Artemis I vehicle on Monday showing both Earth and the ...
Near-Earth comets (NECs) are objects in a near-Earth orbit with a tail or coma made up of dust, gas or ionized particles emitted by a solid nucleus. Comet nuclei are typically less dense than asteroids but they pass Earth at higher relative speeds, thus the impact energy of a comet nucleus is slightly larger than that of a similar-sized ...
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.
