Cepheus constellation is famous for the variable stars in it, as the prototypes of at least three different types of pulsating stars have been found in it. The brightest of these,...

The Complete Guide to Leo Constellation: Origin, History and Facts
Leo and Leo Minor Leo is one of the most recognisable signs of the zodiac. In mythology, it is Nemean the Lion, who was slain by the great hero Hercules.

Almost every culture in the world imagines this constellation as a lion. As one of the 12 tasks of Hercules, Nimean the Lion was killed. The large curved arc on the front side of the constellation forms the famous “Scythe of...
How does the International Space Station maintain the cabin environment?
The International Space Station (also known as ISS) is an artificial satellite that orbits the Earth at an altitude of at least 321.8 kilometers (200 miles). There are 5-6 astronauts on the ISS doing research, experiments, and so on. They do a range of things that give us a better understanding of how everything will work in space. International Space Station: The International Space Station is the most expensive object ever built by man (Photo: Wikipedia) It is obvious that there must be some mechanism, some system to ensure that the astronauts are as comfortable as possible on the space...
How far are we from the sun?
How close can we get to the sun? Robert Goddard created the world’s first liquid-fueled rocket in 1926, the Soviet Union launched an artificial Earth satellite in 1957, and about five years later, Yuri Gagarin became the first man getting into space. Sometime in the late 1960s, the world watched Neil Armstrong and Buzz Aldrin walk on the moon. And then, Voyager 1, launched in 1977, reached Saturn and its largest satellite, Titan. After that it moved further and further away from the sun. Thirty years after its launch, our gaze on the universe is extending more and more frequently...
What are the most important things to survive on Mars?
“Now, you want to settle on Mars. Although it is somewhat smaller than Earth, it still has vast land . Where is the most suitable place to settle?” NASA’s credo is to follow the water – they’re looking for evidence of the existence of life. It’s good advice for past and future humans. Water is heavy and nearly incompressible, so bringing it along to Mars is very expensive and difficult. That’s why finding water locally on Mars is the key to success. In addition, water is not just for drinking: it can be broken down into hydrogen and oxygen, which can...
In the era of rapid development of spaceflight, can space travel be realized?
What are the future of space travel? From early on, mankind has lots of inspiration, enlightenment and excitement to the stars. In the twentieth century, we took a major step forward in space exploration with the launch of the first artificial satellite in the 1950s, followed by the successful lunar landing of Apollo 11 in 1969 and the establish of the International Space Station in 1998. Today, given the growing concern about global warming and climate change, our vision is broader and more ambitious. It’s probably not hard to understand why NASA, Space X, Boeing and other companies are working on...
Best Books on Saturn
Saturn is one of the eight planets in the solar system, sixth in distance from the sun. And the name of Saturn comes from the Roman god of agriculture, Saturn. Saturn is a gas giant, made mostly of hydrogen, with small amounts of helium and elements. And an inner core of rock and ice surrounded by layers of metallic hydrogen and gas. Moreover, with winds of up to 1,800 kilometers per hour, Saturn’s winds are obviously faster than Jupiter’s. Saturn’s planetary magnetic field is between the strength of Earth’s and Jupiter’s. Saturn has a remarkable ring system consisting mainly of icy particles, less rock debris...
