Discover what exist in the universe
SN15X is a space mission to study the solar system, and the universe beyond. sn15X will be launched in 2020 by ISRO (Indian Space Research Organization). It is an unmanned interplanetary mission that will study 70 different asteroids in our solar system for six months. The estimated cost of this […]
A Telescope is a telescope that detects radio signals emitted by celestial objects, such as stars, planets, and galaxies. A type of transducer, it converts electromagnetic waves in the atmosphere or in space into electrical signals which are amplified to be converted back into images in the form of sound […]
All you need to know about our Nearest Star System Alpha Centauri is the nearest star system to our Star Sun. It is about 4.37 light-years away from us. Alpha Centauri (known as Proxima Centauri) is a three-star system named Alpha Centauri A, Alpha Centauri B and Alpha Centauri C. […]
The Sun is a massive ball of incandescent gas. It is a star and the nearest to Earth. The mass of the Sun is 1,989 times that of Earth. The volume is 1,300,000 times greater than that of Earth. About 30% of its group is hydrogen, 70% helium, and other […]
Neutrinos are tiny, neutral particles that are created in the big bang. They’re so small they can pass through a light-year of lead without interacting with any matter. They come from the Sun and other nuclear reactions and radioactive decay. To study neutrinos, scientists use large particle detectors buried deep […]
What Are Neutrinos? Neutrinos are tiny, almost massless particles. They are reproduced by nuclear reactions in the Sun and other stars, radioactive decay, and high-energy cosmic rays striking the Earth’s atmosphere. Electrically neutral, they can stream through ordinary matter with little or no interaction. Neutrinos are subatomic particles with no […]
The Sun is a giant star. It’s the biggest of all the stars. It has a diameter of 1,392,684 km (865,374 miles). To give you an idea of how big that is: if the Sun was hollow and you could shrink the Earth down to a single grain of sand, […]
The Sun is a ball of hot gasses present in the solar system, and it is also one of the largest celestial bodies. It is a perfect sphere of hot gasses with an internal convective movement that generates a magnetic field through a dynamo method. It is an almost perfect […]
A star’s mass determines its color and lifetime. Blue giants are massive stars, much more massive than the Sun, but they don’t burn as long as red dwarfs. This shade of blue is slightly different from what you see in the sky every night. The celestial kind is produced by […]
Red giants are stars that have exhausted their core hydrogen and helium and expanded to millions of miles wide. They burn heavier elements in their cores, resulting in a giant star with a swollen atmosphere. In the final stage of its stellar evolution, a red giant is a large, glowing […]
