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…
A contact lens is a lens that attaches directly to the surface of the eye. Abbreviated as C.L- and just Contacts. Contacts are often used to correct vision defects or facial expressions.

Radio images reveal fast-moving electrons interacting with the galaxy’s magnetic field. They help us map atomic and molecular hydrogen and hot ionized regions. Infrared images show where starlight heats the interstellar gas and dust and reveal red giants, planetary nebulae, and young, massive stars deeply embedded in their parental molecular gas clouds. Visible light shows…
An explosion from a new and unnamed sunspot created the X-Class flame, the first of the 25 solar cycles. An X-ray explosion travels to Earth at the speed of light and collides with the upper part of our atmosphere, causing a shortwave radio blackout in the Atlantic Ocean and coastal areas. The blackout map above…
Pegasus is a constellation near Pisces. 51 Pegasi is a star that is barely visible to the naked eye. It is about 50 light-years from Earth. That is, when we see that star, we see light that traveled five decades ago. Michel Mayor and Didier Queloz, researchers at the University of Geneva in Switzerland, who…
