Bliss, originally titled Bucolic Green Hills, is the default wallpaper of Microsoft's Windows XP operating system. It is a photograph of a green rolling hills and daytime sky with cirrus clouds . Charles O'Rear , a former National Geographic photographer, took the photo in January 1998 near the Napa – Sonoma county line, California, after a ...
Fenton's pictures during the Crimean War were one of the first cases of war photography, with Valley of the Shadow of Death considered "the most eloquent metaphor of warfare" by The Oxford Companion to the Photograph.

50 k (−220 °c; −370 °f OGLE-2005-BLG-390Lb (known sometimes as Hoth by NASA [ 1 ] ) is a super-Earth ice exoplanet orbiting OGLE-2005-BLG-390L , a star 21,500 ± 3,300 light-years (6,600 ± 1,000 parsecs ) from Earth near the center of the Milky Way , making it one of the most distant planets known.
It is the second super-Earth for which astronomers have determined the mass and radius, giving vital clues about its structure. The radius of GJ 1214 b can be inferred from the amount of dimming seen when the planet crosses in front of its parent star as viewed from Earth, yielding a radius of 2.742 +0.050 −0.053 R 🜨. [3]
HD 95086 b's brightness at 3.8 μm when combined with sensitive upper limits on its brightness at shorter wavelengths [12] is consistent with trends seen for other young, directly imaged planets like those around HR 8799. In particular, the lower limit of its 1.65–3.8 μm color of 3.1 magnitudes excludes background stars and most brown dwarfs.
Gliese 667 Cc (also known as GJ 667 Cc, HR 6426 Cc, or HD 156384 Cc) [2] is an exoplanet orbiting within the habitable zone of the red dwarf star Gliese 667 C, which is a member of the Gliese 667 triple star system, approximately 23.62 light-years (7.24 parsecs; 223.5 trillion kilometres) away in the constellation of Scorpius.
The size of the star was calculated using the Rosseland Radius, the location at which the optical depth is 2 ⁄ 3, [55] with two modern distances of 1.14 +0.11 −0.09 and 1.20 +0.13 −0.10 kpc. [40] [10] Its angular diameter was directly measured at 11.3 ± 0.3 mas, which corresponds to a radius of 1,420 ± 120 R ☉ at a distance of 1.17 +0 ...
Luhman 16 (also designated WISE 1049−5319 or WISE J104915.57−531906.1) is a binary brown-dwarf system in the southern constellation Vela at a distance of 6.51 light-years (2.00 parsecs) from the Sun.
