Venus is covered by clouds of opaque and light-reflecting sulfuric acid, and Venus has a darker atmosphere than all other rocks.

Mercury Planet Facts

August 25, 2021

SizeMercury is the smallest planet in the Solar System in mass and diameter. It is slightly larger than Earth’s Moon. HeatMercury’s surface temperatures range from −173 degrees C at night to 427 degrees C during the day. This is because the planet does not have the atmosphere to trap heat, and the energy from the…

GEODYNAMO

August 25, 2021

Is it enough for a planet to be in a habitable zone for life to exist? Any planet standing there would have to receive strong radiation from its parent star. It will eventually melt the planet’s atmosphere. (But the thick clouds on Venus reflect solar radiation, which is why they shine). The movement of molten…

galaxy -#2

August 25, 2021

Galaxies can be classified into three main types: elliptical, spiral, and irregular. Hubble’s morphological classification is a more detailed taxonomic method. Since the Hubble method classifies galaxies only on the basis of shape, it ignores the rate of star formation in Starburst galaxies and the number of active galaxies. Elliptical. (Elliptical galaxy) The Hubble taxonomy…

How many types of planets are there in terms of mass system?

August 24, 2021

Astronomers studying celestial objects such as planets have revealed eight classifications based on mass systems. Billions of objects have been discovered in space, and astronomers make such discoveries every year. Planets are some of the most common celestial objects, and the most studied. Astronomers have come up with various classifications used to classify the planets….

How Many Satellites Are There In Space

August 24, 2021

Satellites are launched into space to perform a specific mission, and are specially designed to perform the required function. A satellite is a man-made object that is placed in orbit to fulfill a specific mission. Also known as man-made artificial satellites, they are different from natural moons, such as the moon. Different moons are classified…

Aliens watching us?

August 24, 2021

Two years ago, on April 20, 2019, scientists received a unique radio signal from Alpha Centauri, 4 light years away from us. After much study, scientists arrived on December 20, 2020, concluding that it was more likely to be an alien signal. There are many valid reasons to come to such a conclusion. One of…
