Confirmation of loss of contact with Voyager 2, currently approximately 21 billion kilometers from Earth. On July 21, commands sent from Earth to Voyager 2 accidentally caused Voyager’s High Gain Antenna to point 2 degrees away from Earth. Therefore Voyager cannot currently receive messages from Earth or send messages in the direction of Earth. A…
The Manhattan Project nicknamed the Trinity Test was the most top secret nuclear test conducted by the United States. The movie Oppenheimer was released about it.Only a handful of people knew about it…after the test America dropped the nuclear bomb on Japan. But after this trinity test there was another group in this world who…
As far as we know, the universe is made up of fundamental particles like electrons and quarks. Everything we see in the universe, including ourselves, is the result of interactions between these particles. Fundamental forces mean interactions of elementary particles. Four fundamental forces have been identified. They are gravitational force, electromagnetic force, weak nuclear force…
The location is the 4,000-acre bottom of dry Ivanpah Lake in California’s Mojave Desert. Three hundred thousand movable mirrors, curved around the three towers, capture energy from the sun, reflect it, and vaporize the water at the top of the tower at temperatures above 500 degrees Celsius. This steam is used to spin the lower…

NGC 6888, also known as the Crescent Nebula, is a cosmic bubble about 25 light-years across, blown by winds from its central, bright, massive star. This beautiful telescopic view combines a composite color image with narrow band data that isolates light from hydrogen and oxygen atoms in the wind-blown nebula. The oxygen atoms produce the…
You don’t need to be an expert in science to understand that black holes often pull things in rather than spit them out. However, NASA has just discovered something quite weird around the supermassive black hole Markarian 335. Two NASA satellite telescopes, including the Nuclear Spectroscopic Telescope Array (NuSTAR), witnessed a black hole’s corona being…
