suppose you were looking at our own solar system from a distance of 9.0 light-years. What angular resolution would you need to see the Sun and Jupiter as distinct points of light

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

the inner core.

good luck: )
