As we cannot yet travel outside the solar system, we have to learn as much as we can about the stars by studying them at a distance. Astronomers can tell the brightness, color, and temperature of a star by analyzing the light it gives out.
By splitting starlight into its constituent colors, they can find out what the stars are made of and how fast they are moving.
Stars are so far away, we are not normally aware of their movement through space. But over time this movement, called proper motion, changes the shapes of constellations dramatically.
Astronomers can figure out a constellation’s past and future shape by precisely measuring the positions of its stars over several years.

What Gravity does to Entropy
What qualifies as low entropy or high entropy depends on the situation. Physicists identify the high – entropy state of a system based on how the system evolves over time. For example, if a diffuse and sufficiently cool gas feels the tug of gravity, it evolves to a clump. The law of entropy increase then implies that the clump has high entropy, even though at first glance it might appear to be...

Lunar Eclipses Explained
A eclipse occurs when the Moon passes straight at the rear of the Earth into its umbra (shadow). This will happen only once the sun's rays, Earth, and Celestial satellite are aligned specifically, or extremely closely thus, using the World in the middle. Therefore, the eclipse can only occur the night time of your full-of-the-moon. The sort and also period of a great eclipse depend upon the Mo...

How Eclipses of the Sun Happen
In its 27 – day Orbit of the Earth, the Moon sometimes passes directly in front of the Sun and we see a solar eclipse. In one of the natural world’s most eerie, beautiful spectacles, the dark circle of the Moon gradually creeps over the Sun. Between two and five solar eclipses are visible from somewhere on the Earth each year. When the Moon is at its farthest from the Earth, it is not ...

How the Moon Influences the Earth
Although the moon is much smaller than the Earth, it still has an influence on its bigger companion. Just as the Earth’s gravity pulls on the Moon, the gravity of the Moon pulls on the Earth, stretching it into a slight oval. This distortion barely affects the solid landmasses, but it makes the oceans bulge on either side of the planet, producing the tides on either side of the planet. ...

Red Giant Stars Explained
A red monster is an iridescent monster star of level or halfway mass (harshly 0.5–10 sun oriented masses) in a late stage of stellar development. The external environment is swelled and tenuous, making the span monstrous and the surface temperature flat, an as yet undisclosed place from 5,000 K and easier. The manifestation of the red monster is from yellow orange to red, incorporating the unearth...

Diagram of the Space Station Life Support System
This diagram shows how astronauts live on the space station. Everything is attempted to be recovered on the space station. The urine that astronauts dispense from their bodies is reused as water. Waste water is then reused to create oxygen. Co2 is removed through overboard venting. It's amazing how much everything is reused on board.

A Brief History of the Solar System
The process of existence or initiative of life in the Solar System looks very interesting. Life in the solar system is a monomeric nucleotide, pretty much just a simple molecular compound made out of a normal, every-day inorganic material.

Radio Astronomy
Radio waves are the same type of waves as light. They have less energy than visible light and so have a longer wavelength, but they travel at the same speed as light. At night our eyes and optical telescopes sees light from stars. But normal stars only produce radio waves very weakly.
