5 facts about space срочно

Answer 1

Facts about space

1) One million Earths could fit inside the sun – and the sun is considered an average-size star.

2) For years it was believed that Earth was the only planet in our solar system with liquid water. More recently, NASA revealed its strongest evidence yet that there is intermittent running water on Mars, too!

3) Comets are leftovers from the creation of our solar system about 4.5 billion years ago – they consist of sand, ice and carbon dioxide.

4) You wouldn’t be able to walk on Jupiter, Saturn, Uranus or Neptune because they have no solid surface!

5) If you could fly a plane to Pluto, the trip would take more than 800 years!

Answer 2

Certainly, here are five fascinating facts about space:

1. Vastness of Space: Space is incredibly vast. The observable universe is estimated to be about 93 billion light-years in diameter, containing billions of galaxies, each with billions of stars.

2. No Sound in Space: Space is a vacuum, meaning it is devoid of matter, including air. As a result, there is no medium for sound to travel through, so space is completely silent.

3. Microgravity Effects: Astronauts in space experience microgravity, which can have profound effects on the human body, including muscle atrophy, bone loss, and fluid redistribution. This is why astronauts aboard the International Space Station (ISS) exercise daily to counteract these effects.

4. Extreme Temperatures: Space can be extremely cold and hot. In the absence of an atmosphere, there is no medium to conduct heat, so objects in space can experience temperatures ranging from hundreds of degrees below freezing to hundreds of degrees above boiling.

5. Cosmic Phenomena: Space is home to many intriguing cosmic phenomena, such as black holes, supernovae, pulsars, and quasars. These objects are the result of extreme physical processes and can teach us a lot about the nature of the universe.

These facts highlight the incredible, mysterious, and often challenging nature of space.
