The so-called 'solar wind' is a flow of charged particles that are injurious to
living tissue. The reason we never worry about it is that we're protected
from it by the Earth's atmosphere and magnetic field. But if the living
human tissue happens to be in space, in a tin can headed for Mars, then
the Earth's atmosphere and magnetic field are suddenly not there, and
the tissue needs to be shielded somehow from the solar wind particles.
===============================
Because it is so strong that it could blow your spacecraft off-course, and
you would have to use a lot of your precious and limited fuel to keep your
ship on the proper heading toward where you're going to.
A trip to Mars takes months and involves crossing several million miles of space. This is enough time for the solar widn to affect the trajectory of a space craft.
The atmosphere of these planets is not suitable for human exploration. Gases and extreme pressure would instantaneously kill astronauts. Funding and the distance to the gaseous would also be reasons we have not visited Jupiter or Saturn.
Far more expensive and far less productive.
I would suppose that the scientist with the super powered telescopes would discover planets before the astronauts would.
So far, with current technology, yes. Note that the nearest stars are in the order of 10,000 to 100,000 times farther than the planets in our own Solar System. You might imagine a technology that allows astronauts to travel to such other star systems, but that would require enormous technological breakthroughs, and the trip may well take generations - or require the astronauts to be put in some sort of artificial hybernation - another technological breakthrough we haven't achieved yet.
OBVIOUSLY

The main consumers of solar energy would be human beings.
I would be worried about any individual who was notworried. It is human nature to be concerned and nervous about the unknown.
What arguments would you use to convince a friend that the lives of human beings are dependent on solar energy?

There have never been, nor will there ever be, Astronauts who land on Saturn. The gravity is too great, the air pressures are too high and the atmosphere is toxic to human life. A human would be crushed by his/her own weight given the gravity on Saturn. A human could not tolerate the atmospheric pressures on Saturn. A human could not endure the gasses in Saturn's atmosphere.
it would over heat. Black objects typically have a higher solar heat gain coefficient than lighter colors.
She was worried that she would be executed
I suppose you could say "A worried lot" if you mean lot as the noun, and a group of people are all worried, but I would say "The whole group is worried" instead. If you mean that you are worried often, you would say "I get worried a lot" and if you mean that you are extremely worried, then you would say "I am a lot worried" or "I am very worried" which sounds a little better.
