The branch of science that has to do
with celestial objects, space, & the
physical universe as a whole.
What am I doing talking about astronomy??
What gives me the right if
I have no
education in it?
Well I want to major in astronomy or quantum mechanics
Noone is really sure about when or where
astronomy first started...
Perhaps a lost hunter followed the setting sun towards his home and then was able to keep traveling when he realized that a star in the sky was shining steadily in the same direction.
A New Discovery in Astronomy
Super-Earth
A small planet, about 4.5x bigger
than Earth, could be possibly
inhabitable. Although it's in a
triple-star system, it travels around
them in a rather cool zone.
It take Super-Earth about 28 days
to make 1 full revolution.It has at least one super-Earth companion orbiting on a tighter orbit in just 7.2 days.
The 3 stars that this revolves around
are just 3 little orange dwarf stars. These stars have only a quarter of the heavy elements that our Sun possesses, depleted in some of the metal-rich ingredients that go into planet building.
This planet is thought to absorb the same amount of sunlight that our Earth does, though in the form of infrared radation. Traveling in a habitable zone puts Super-Earth as the best canidate to support liquid water.
Astronomers from the European Southern Observatory have found that, even though Super-Earth is a small planet, the 3 stars that it revolves around are even smaller that there are small tugs on the stars from the planet's gravitational pull.

Could of been a very observant caveman
who got his attention taken away
by a shooting star.

sooo... I'm kind of learning from this too.
