SPACE IS COMPLETELY SILENT
There is no atmosphere in space, which means that sound has no medium or way to travel to be heard. Astronauts use radios to stay in communication while in space, since radio waves can still be send and received.
THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450 DEGREES C
Venus is the hottest planet in the solar system and has an average surface temperature of around 450 degrees. Interestingly Venus is not the closet planet to the sun - Mercury is closer but because Mercury has no atmosphere to regulate temperature it has a very large temperature fluctuation.
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight.
Astronauts and cosmonauts on the space station stay busy. There's lots of work to operate the many science experiments on board. The crew also has to make sure that the station is in top shape, so they clean, check equipment, maintain and repair or replace broken equipment.
We are yet to see space tourism take off, but astronauts travelling to and from the International Space Station has almost become routine in the 48 years since people last set foot on the moon. New players in this space and the latest developments are making space travel in the next ten years increasingly more likely.
