Kepler-22b

A comparison of kepler-22b and earth Kepler-22b is an exoplanet located about 600 light-years away from Earth in the constellation Cygnus. It was discovered by Kepler spacecraft in December 2011, it was launched in 2009 on the mission of finding planets outside our solar system which are known as exoplanets. The discovery of Kepler-22b was announced after more than a year of observation and analysis of data from the spacecraft. The planet was detected by using the transit method it involves measuring the small decrease in the brightness of a star which occurs when a planet passes in front of it. Kepler-22b orbits a star called Kepler-22, Kepler-22b is known as a super-Earth, it means that it has a radius that is larger than Earth's but smaller than Neptune's. It is believed that its radius is 2.4 times that of Earth, and its mass is considered to be almost 35 times that of Earth. The planet orbits its star at a distance of almost 85 million miles (137 million kilometers) that i

History of cricket bats

First shoulderless bats were introduced in 1960's from salazenger. Imran Khan playing with shoulderless cricket bat  Double sided bats were first introduced in 1970's from warsop stebbing and first GN100 scoop was released in 1974. In 1979 Dennis Lillee used a combat aluminum metal bat. Dennis Lillee holding his combat aluminum metal bat  In 2004 Newbery created the uzi bat for t20. Uzi bats In 2005

James Webb Space Telescope(JWST)

Image
  James Webb telescope  James webb space telescope (JWST) was launched on December 25, 2021.It sent it's first pictures in 2022.It is approximately 15 lakh kilometers from earth. According to NASA it takes just five seconds for data to reach earth from the telescope which is then directed to the mission centers. Some of the first images of James Webb are: Carina nebula  Carina nebula is nicknamed as the cosmic cliffs.This picture looks like “mountains” and “valleys” with beautiful stars but actually it is the edge of a young, star-forming region called NGC 3324 in the Carina nebula. Stephan's Quintet  It is a  group of five galaxies which is mostly known for being featured in a holiday film, “It’s a Wonderful Life.” Southern Ring Nebula Two cameras on james Webb captured the recent image of this nebula which is known as the Southern Ring Nebula. This nebula is almost 2,500 light-years away from earth. The detailed images that James webb have delivered are among the most breatht

Hubble space telescope(HST)

Image
Hubble space telescope(HST) The Hubble Space Telescope (HST) is a powerful astronomical observatory located in low Earth orbit. The idea of a space telescope was first proposed in the 1940s, but it wasn't until the 1960s that the concept gained momentum. In 1977, NASA selected a team of scientists and engineers to develop a space telescope, and the project was named the Hubble Space Telescope in honor of Edwin Hubble, who is widely regarded as one of the greatest astronomers of the 20th century who made significant contributions to our understanding of the universe. The HST is operated by the National Aeronautics and Space Administration (NASA) in partnership with the European Space Agency (ESA).It was designed to be a general-purpose instrument, capable of observing a wide range of objects and phenomena in space, from planets and moons in our solar system to the most distant galaxies in the universe. The telescope is approximately the size of a large school bus and weighs nearly 2
