  1I/2017 U1 'Oumuamua' is the scientific name of Omuamua   Omuamua was the most recent interstellar object detected while passing through the solar system. 1I/2017 U1 ‘Oumuamua, was discovered on October 19, 2017, by the University of Hawaii’s Pan-STARRS1 telescope, which is funded by NASA’s Near-Earth Object Observations (NEOO) Program, which finds and tracks asteroids and comets in Earth’s neighborhood. Initially, it was classified as a comet but after some observations like speed and direction of path no signs of cometary activity were revealed as it slingshotted past the Sun on Sept. 9, 2017, at a blistering speed of 196,000 miles per hour (87.3 kilometers per second).   Size, Shape, and specifications Omuamua was The first confirmed object from another star to visit our solar system, It was looking like a rocky body and somewhat cigar-shaped object, very weird straight and slim shape and its color was reddish hue due to effects of irradiation from cosmic rays over ...

Is Mars Our Future Or Not?

-

  Mars is the 4th planet of our solar system and the nearest planet of Earth. 1610 was the year when Galileo Galilei discovered Mars with telescopic observation, the distance between the sun and mars is 228.19 million km. Behind the mars, there is the belt of so many Asteroids. The orbital period is 687 days which is quite more than the earth’s orbital period. Planet Mars is surrounded by so many artificial ( manmade) satellites. But mars have 2 natural satellites named Phobos and Deimos. Colonization on a different planet is also known as the Space settlement it is the political concept of space law for human habitation and the taking advantage of all-natural resources of that planet where we want to colonize. Yes, we can colonize Mars but it is too difficult to survive due to some issues.  Mars is on the boundary of the Habitable zone. A habitable zone is simply the orbit at a certain distance from the star where a planet or planetary surface can support water with sufficien...

Evidences for the Dark Matter

  Dark matter is known  as the “missing mass,” dark matter’s existence was first inferred by Swiss American astronomer Fritz Zwicky, who in 1933 discovered that the mass of all the stars in the Coma cluster of galaxies provided only about 1 percent of the mass needed to keep the galaxies from escaping the cluster’s gravitational pull.  In this blog we will discuss 5 different pieces of evidence for the existence of the dark matter  BENDING OF LIGHT Gravitational lensing:- The amount of bending is proportional to the mass of the object that causing the bending,  Light gets bent due to the mass of the object. In this image light from the distant galaxy is lensed due to galaxy clusters, so we get lensed images here on the earth. But we are getting an extra lensed image than usual but the Amount of bending is proportional to the mass of the object, so there is evidence of missing mass, We get the factor of the Dark matter here. We can derive the formula for this...
