Question

1:-How can you recognise the planets Venus, Mars, and Saturn in the sky. 2:-Why is life found only on the earth.

Answer 1

1) For one, Venus is brighter than any other object except the Moon and Sun. So it’s pretty easy to spot. (Presently it’s in the western, evening sky.)

Mars isn’t too hard - it’s kind of a burnt orange color. Knowing where it is 20–22 months at a time helps, as it’s often around 1st magnitude. It can easily be confused with Antares (anti-Mars!) when the red planet is in Scorpio. It brightens up considerably near/at opposition.

Saturn is kind of creamy colored. Usually at 1st magnitude, it can blend in with the other bright stars pretty well.

However, all of the planets travel on/near the ecliptic (zodiac constellations). And once you know the stars along the ecliptic, recognizing the planets isn’t too difficult.



2) We do know that life as we understand it requires very special conditions to exist. In fact, many scientists believe that these conditions exist elsewhere and offer the possibility for life beyond just our Earth. These may be very simple organisms such as bacteria or even more complex life such as plants and animals
