I was browsing through the website (great and interesting information by the way!) , and I was wondering, how exactly are astronomers able to photograph the Milky Way if we are technically in it? Isn't it like trying to take a picture of the outside of your house while being IN your house? Thank you for your time! It's more like trying to take a picture of the inside of your house while you are inside it, and while your house is cluttered with a bunch of junk to boot! Because we are inside the Milky Way, we don't get to take any pictures of it from an angle "above" the galaxy - for example, like this beautiful picture of M31, the Andromeda Galaxy. The Size Of Our World - StumbleUpon. Our Solar System: Facts, Discovery, Exploration &Formation. The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets and meteoroids.
It extends from the sun, called Sol by the ancient Romans, and goes past the four inner planets, through the Asteroid Belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the giant, spherical Oort Cloud and the teardrop-shaped heliopause. Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun.
For millennia, astronomers have followed points of light that seemed to move among the stars. The ancient Greeks named these planets, meaning "wanderers. " Mercury, Venus, Mars, Jupiter and Saturn were known in antiquity, and the invention of the telescope added the Asteroid Belt, Uranus, Neptune, Pluto and many of these worlds' moons. Can Life Thrive Around a Red Dwarf Star? Roughly three quarters of the stars in the galaxy are red dwarfs, but planet searches have typically passed over these tiny faint stars because they were thought to be unfriendly to potential life forms.
But this prejudice has softened lately. Preliminary results from a dedicated research program have shown that planets around red dwarfs could be habitable if they can maintain a magnetic field for a few billion years. Red dwarfs — also called M dwarfs — are between 7 and 60 percent as massive as our sun. ? Their lower mass means they don? T burn as hot or as brightly, emitting less than 5 percent as much light as the sun. To understand the environment around these common stars, the "Living with a Red Dwarf" program was started three years ago.
"This is the information that you would want to know to model the suitability for life on a nearby planet," says Ed Guinan of Villanova University, a scientist working with the program. Death lock Still, life might not be a picnic around a red dwarf. The Solar System Looks Way Better Than It Used To. Rocket launch blows away the sky.
