The RQ-3 DarkStar (known as Tier III-or "Tier three minus" during development) is an unmanned aerial vehicle (UAV). Its first flight was on March 29, 1996. The Department of Defense terminated DarkStar in January 1999, after determining the UAV was not aerodynamically stable and was not meeting cost and performance objectives. [1]
In April 2023, a study investigated four extremely redshifted objects discovered by the James Webb Space Telescope. [5] Their study suggested that three of these four, namely JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0, are consistent with being point sources, and further suggested that the only point sources which could exist in this time and be bright enough to be observed at these ...
During 1783 geologist John Michell wrote a letter to Henry Cavendish outlining the expected properties of dark stars, published by The Royal Society in their 1784 volume. . Michell calculated that when the escape velocity at the surface of a star was equal to or greater than lightspeed, the generated light would be gravitationally trapped so that the star would not be visible to a distant astron

Development of the Y-9 may have begun as early as 2002 as the Y-8X program. The program was a collaborative effort with Antonov – the designers of the An-12 that it was ultimately derived from – and was aimed at competing with the Lockheed Martin C-130J Super Hercules. By September 2005, the Y-9 designation was being used. [4]
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
I'm an experienced skier who has been to more than a dozen ski resorts around the world.. I often see beginners make mistakes such as holding up lines, tailgating, and zooming down slopes. Wearing ...
In a June 2014 interview with the Jenkem online publication, Thomas explained that the Dwindle Distribution company—responsible for the Enjoi, Blind Skateboards, Almost Skateboards, Darkstar and Cliché Skateboards brands—will take over "the sales, finance, production and distribution aspects" of the Zero brand.
