25 years of planetary hunting

August 25, 2021

The Solar System, in which the planet Earth. The only place in the universe where we can now say for sure that there is life.It is this thought that touches the depths of human curiosity that mainly motivates us to discover the planets outside the solar system.One of man’s primitive curiosities is whether life exists…

How do we know the atmosoheric composition, size, temperature, etc. of millions of other planets farther away from Earth?

August 25, 2021

When we look through a Kepler telescope. The size is determined by looking at the amount of light that passes through the front of a planetary star.It calculates the year by looking at the time differences that pass through itThen the atmospheres can be understood by looking at the spectrum of a planet as it…

Why is Mercury hotter than Mercury, even though it is closer to the Sun than Venus (475 degrees c)?

August 25, 2021

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

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

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….

What is the difference between asteroids and comets?

August 24, 2021

For centuries, people have looked up at the night sky and wondered about what they see and beyond. Over time, with the development of the study of space and astronomy, scientists slowly began to answer these questions, naming different objects in space and predicting certain astronomical events. For those unfamiliar with the study of astronomy,…
