How do scientists learn more about planets?

By observing them regularly using telescopes and by sending orbital or lander probes to them.


Why do you send out space probes insted of actual space flights with astronauts?

NASA occasionally sends out space probes instead of humans because astronauts could not survive on some of the places that space probes are sent to.


Have astronauts sent any probes to Jupiter?

yes


What are some names of a space exploration?

Robot space probes and telescopes


What are the different methods of investergateing the universe?

Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.

How do scientists collect data about our solar system and the universe?

Through telescopes. We have more ground based telescopes than we have instruments in space, though we have also learned a great deal through some space missions, such as through the COBE & WMAP satellites. Optical telescopes provide a wealth of information, but we can see further using radiotelescopes, and we can penetrate deeper through clouds of interstellar gas with infrared telescopes.


How do we explore space from earth?

We use space probes, and send astronauts... etc.


Why is it cheaper to send space probes then people to other planets?

Sending space probes is cheaper than sending people to other planets because space probes are typically smaller, lighter, and require less infrastructure to support life support systems and return missions. Human missions have to account for the safety, health, and well-being of the astronauts, resulting in significantly higher costs. Additionally, space probes can be designed for specific tasks and don't require return trips, whereas human missions would need to account for the return journey.


What are the different tools used to study the universe?

The different tools are satellites, probes, telescopes. and spacecrafts.
