Explanation

The James Webb Space Telescope (JWST) primarily uses infrared rays to capture images of distant objects in the univers

Explanation

• Earth revolves in orbit around the sun in one year, 6 hours, nine mins on the subject of the stars, at a velocity starting from 29.29 to 30.29 km/s.
• The 6 hours, 9 mins adds as much as approximately an extra day each fourth year, that's particular a leap year, with the more day brought as February twenty ninth.
• Earth's orbit is elliptical and reaches its closest method to the sun, a perihelion of 147,090,000 km, on approximately January fourth of each yr. Aphelion comes six months later at 152,100,000 km.
  

Explanation

CNES is a space agency in France

CNES stands for National Centre for Space Studies.

CNES Formed  in 19 December 1961

Explanation

The smallest planet in terms of mass and volume is Mercury. With a diameter of 4,879 km  and 3.3010 x 1023 kg, this small world weighs about one-twentieth the mass of the Earth and  is about one-2.5th the diameter. In fact, Mercury is closer  to our moon than  Earth.

Explanation

Mercury revolves around the Sun every 88 days, but its rotation takes nearly 59 days. 

Explanation

The constellation of seven bright stars known as the Great Bear is Ursa Major, which also includes the Big Dipper asterism: 

Name:

The Latin name Ursa Major means "greater (or larger) bear". 

Size:

Ursa Major is the third-largest constellation in the sky and the largest in the Northern Hemisphere

Explanation

• according to some scientists, 100 Billion galaxies are there in the universe
• ***
• Hubble reveals an estimated 100 billion galaxies in the universe or so,
• but this number is likely to increase to about 200 billion 
  
• ****
• IN 2021:
• a previous measurement by the Hubble Space Telescope suggested there were 2 trillion galaxies spread across the universe. But the latest discovery counts only hundreds of billions of galaxies instead
• ***
• in 2022:
• The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.
• ****
• Hubble is the name of the Space Telescope named by Edwin Hubble, in the 1920s

Explanation

Every planet in our solar system except for Venus and Uranus rotates counter-clockwise as seen from above the North Pole; that is to say, from west to east.

This is the same direction in which all the planets orbit the sun. Uranus was likely hit by a very large planetoid early in its history, causing it to rotate "on its side," 90 degrees away from its orbital motion.

Venus rotates backwards compared to the other planets, also likely due to an early asteroid hit which disturbed its original rotation.
