INSIDE SCIENCE

  Vega Lyra is the brightest star in the Constellation Lyra . It has the title of the alpha Lyra in the Constellation Lyra. It exists 25 light years away from us. Vega has always been a topic of discussion in astronomers. Today we will discuss it. If we talk about its name then it comes from, Arabic word. In Arabic, it is called “ waqi ” it means falling. Vega is presently the Fifth brightest star in the night. Vega is associated with the name Abhijit in Hindu culture .it is the brightest star in the north celestial hemisphere . You can easily see the Lyra constellation in the night sky. Today Polaris is our North Star it does not change its position when its sees the earth. This is because the earth rotation axis is completely tilted towards the Polaris. At the moment Polaris is our northern star, the brightest star in the constellation Ursa Minor . But in 3000 B.C. The earth’s North Star was Vega and after 13000 years Vega will become our North Star again. There are several

  There are more than 250 moons in our solar system . All planets except mercury and Venus have their own moons. Jupiter and Saturn have the largest number of moon on any other planets in our solar system. Jupiter   has about 79 moons and Saturn has 82 moons. Of   Saturn ’s 82 moons, Titan has been the subject of much discussion since its discovery. Titan is the second largest moon in our solar system after  Ganymede .  Image source-google| image by Kelvinsong Titan is the largest moon of Saturn moon. On Saturn and it is the most special natural satellite in the solar system . What makes it so special is its dense atmosphere and finding solid evidence of the existence of vast oceans and rivers on it. Hence, it also called planet like moon. Titan is larger than our Earth’s moon and is about 78% more massive than our moon. WHO DISCOVER TITAN FIRST On March 25, 1655 Dutch astronomers Christian Huygens first discovered Saturn’s largest moon Titan. Christian Huygens was a Dutch astronomer

1.  Light is a type of electromagnetic radiation. Which the humans eye can easily see. Light, particles and wave can be occur simultaneously in nature. Whatever natural light we see that makes us see everything we get from our sun. There are many types of light for example: Infrared Light, x-rays light, Gamma rays, Ultraviolet light. 2.  The speed of light in highest in space or vacuum. Because these light particles are completely massless. Unlike all other particles, these particles do not interact with the Higgs Field at all. So they travel in space at the speed of 2.99792 km/PS. Because massless particles can travel in space at the same speed. 3.  Infrared Light was discovered by William Herschel. In infrared light infra means ‘below’ in Latin. Because it is below red spectrum of light. This light is invisible, we cannot see it with our naked eyes. We just feel the heat of it.  The difference in light is due to the wavelength. With difference light we can see qualities present i
