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…

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…
Absolute zero is the lowest possible temperature in the universe, where no heat is present. This is a state where all molecular motion ceases entirely. In simpler terms, when there is no movement among the molecules, there is no heat, and this is what we call absolute zero. Heat is the result of molecules moving…

What are they? Let’s explain. Sperm bots are tiny nanorobots designed to aid individuals struggling with infertility. These spiral-shaped robots navigate through semen, much like a small snake, targeting and assisting less motile sperm. Upon locating a sperm cell, the sperm bot captures it within its spiral body, carrying it towards the egg for fertilization….
Hedy Lamarr, often hailed as “the most beautiful woman in the world,” was not only an American film star but also a brilliant electronic engineer whose innovations laid the groundwork for modern wireless communication technologies like Wi-Fi and Bluetooth. Lamarr, a Jewish immigrant from Nazi-occupied Austria, settled in the United States in 1938. Lamarr played…
Suspended in a small turret below a bomber flying at 10 kilometers altitude in freezing temperatures, ball turret gunners faced death every moment as they fired at enemy planes. Only 40% of those who went on these missions returned alive, the rest falling victim to enemy fire in the sky. These gunners had no parachutes…
Europa, the fourth largest of Jupiter’s 95 moons, holds a special place in our solar system. It is the sixth closest moon to Jupiter and, along with Io, Ganymede, and Callisto, was among the first moons discovered beyond Earth. These moons, known as the Galilean moons, were first observed by the Italian astronomer Galileo Galilei,…
