The Wiki Science Competition (WSC) is a global science photography competition for students, researchers, and others to contribute freely licensed high-quality, well-sourced images and other media to Wikimedia Commons. [3] [4] It evolved from the Estonian Science Photo Competition.
Lenna is so widely accepted in the image processing community that Forsén was a guest at the 50th annual Conference of the Society for Imaging Science and Technology (IS&T) in 1997. [16] In 2015, Lena Forsén was also guest of honor at the banquet of IEEE ICIP 2015. [ 17 ]
SMACS J0723.3-7327 – a galaxy cluster at redshift 0.39, with distant background galaxies whose images are distorted and magnified due to gravitational lensing by the cluster. This image has been called Webb's First Deep Field. It was later discovered that in this picture the JWST had also revealed three ancient galaxies that existed shortly ...
The anisotropy, or directional dependency, of the cosmic microwave background is divided into two types: primary anisotropy, due to effects that occur at the surface of last scattering and before; and secondary anisotropy, due to effects such as interactions of the background radiation with intervening hot gas or gravitational potentials, which ...

The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape the understanding of the cosmos.
(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.
Portal:History of science/Picture/2 . An engraving by Albrecht Dürer, from the title page of the Masha'allah ibn Atharī's astronomy treatise De scientia motus orbis (Latin version with engraving, 1504). As in many medieval illustrations, the compass here is an icon of religion as well as science, in reference to God as the architect of creation.
