Hi there! You’ve probably heard of the phrase “learn something new everyday “, and “know a little about everything ” . If you have, this post is written in that context. And if you haven’t. Same information goes to you. Below are earth science terms that I read about once upon a time. You know, “know a little about everything”. I have put them in alphabetical order for you, for easy navigation when you need to come back to read . Am I a darling? Yes or yes? Enjoy!
Absolute magnitude: An absolute magnitude is the magnitude a star would have if it were viewed from a distance of 10parsecs (32-62 light years) from the earth. A light year is the distance light travels in one earth year. One light year is 6 trillion miles.
Alpha Centauri : An Alpha Centauri is the closest bright star to our Solar System, the brightest star in Centaurs and the second nearest star to the sun .
Aphelion : This is the point in the orbit of a planet or other celestial body where it is farthest from the sun.
Asteroid : An Asteroid is a small celestial body in orbit around the sun. It is larger than a meteoroid but smaller than a planet. Most Asteroids are found in a belt between orbits of Mars and Jupiter. The orbit of some asteroids take them close to the sun, which also takes them across the path of the planet.
Aurora : the bands of lights caused by charged solar particles is called an Aurora .
Big Bang : this is the cosmic explosion that is hypothesized to have started the universe. Hypothesis – the universe was a single dense sphere of hydrogen that exploded into a gigantic expanding cloud that eventually condensed into separate galaxies. Theory- the Big Bang theory states that 10-20 billion years ago, all matter exploded from an infinitely compressed state .
Blue Star : Blue stars are the hottest stars. They have a surface temperature of more than 37,000ÃÂF
Brane: Tycho Brane is a Danish astronomer whose observations of the planet provided the basis of Kepler’s law of planetary motion. Johannes Kepler first discovered that the orbits of the planets are ellipses,not circles . His discovery was based on the close observations of Tycho Brane.
Chromosphere: a chromosphere is a gaseous layer of the sun’s atmosphere. It lies above the photosphere. It is Visible during a total eclipse of the sun.
Circumpolar Star : A circumpolar Star is a star that doesn’t set, but stays above the horizon. The further south you go as an observer, the fewer stars will become circumpolar. It all depends on your location. Polaris, the North Star, is circumpolar in most of the northern hemisphere.
Comet: A comet is a small frozen mass that travels around the sun.
Constellation: this is a group of stars that appear to form a pattern in the sky. It is a configuration of stars as seen from the earth.
Cosmic String : this is a tube-like configuration of energy that is believed to have existed in the early universe . A cosmic string would have a thickness smaller than a trillionth of an inch but it’s length would extend from one end of the visible universe to the other .
That is all for today amazing people! Till I see you next week, on another amazing episode of earth science terms. I sound like those radio anchors right now. But yes! See ya!
