Interesting facts about stars?

Question

I need some cool/interesting facts about stars for a science project. Can anybody help? Thank you!

Answer 1

Of course, i can say a lot about the stars. you can get every thing on wiki. Sun: http://www.solarviews.com/eng/sun.htm

http: http://en.wikipedia.org/wiki/Image:Sun_L... - cool huh?

Mars: The average Martian temperature is -63°C, with a high record of 20°C and a low record of -140°C.

the Martian day is 24 hours and 37 minutes Earth time -- pretty close to ours!

the Martian year, on the other hand, is 687 Earth days -- nearly twice Earth's.

Mars's moon Phobos orbits Mars every seven hours (the Moon orbits Earth every 27.3 days.

Martian air contains 1/1000 as much water as Earth's, but still can form clouds, fog, and frost.

if you weighed 100 pounds on Earth, you would only weigh 38 on Mars.  The mass of Mars is 6.4219x10^23 kg, or the mass of 4,700,000,000,000,000,000 blue whales!

Mars has interesting magnetic fields! the presence of what seem to be canals and the placement of rocks in flood-like patterns cause scientists to believe that water once existed on Mars; now the question is where it went! Some studies have said that Mars's lack of magnetosphere may have allowed the solar wind to carry off a huge amount of water from the Martian surface over billions of years.

it's such a challenge -- scientists conclude that living on Mars (without some kind of high-tech provisions) isn't possible because of UV rays and dry, oxidizing soil.

Pluto: Pluto is a small rocky object that lies at the very edge of the solar system. The planet is so far out it takes light from the sun about 5 and one half hours to reach Pluto in contrast to the 8 minutes it takes to reach Earth. Its orbit of about 248 years sometimes takes it inside Neptune’s orbit. Pluto is so cold that nitrogen and oxygen, which we breathe so easily on Earth, become frozen solid. The planet is only about two-thirds the size of our moon and up until recently was the biggest known object in the Kuiper Belt.

This belt is in the same plane of the planets and are the millions of rocks, ice chunks and particles left over from the formation of the solar system. Comets with orbits of less than 200 years, short-period comets, come from this debris. Beyond the Kuiper Belt is a spherical cloud of dust, rocks and ice called the Oort Cloud where long-period comets hide and the solar wind still flows.

Hope that will help! :) and i still didnt include all the stars in the

solar system...

Answer 2

All known stars rotate.

Answer 3

they rotate just like planets do

they have hundreds even thousands of magnetic poles (think hundreds of south poles and north poles existing all over it's surface)

the heat/light is created at it's core.... and the light you're seeing off it actually isn't 8 minutes old (science shows us it takes about 8 minutes for the heat/light to reach earth once it leaves the sun) the energy was actually created about 250,000 years ago deep in it's core and has taken this long to work it's way to the surface

we know of a star that is so big, it would completely encompass jupiter's orbit..... THAT IS MASSIVE these stars shouldn't have even ever formed they are so large.... (just goes to show you nothing is impossible in the universe)

a few years back we disocvered firey tsunami's.... a massive magnetic kink broke, shooting off a huge burst of plasma, which alot collapsed back down, creating a wave of fire miles high, moving at over a thousand miles an hour, and the farthest reaching ripples would easily cover the diamter of the earth (that is HUGE)

Answer 4

The sun emits most of it's radiation in the form of visible light which probably is no coincidence that human beings have evolved to be able to see only visible light.

The largest star in diameter is about 3000 times the size of the sun and if it were in place of the sun it would be about the size of Saturn's orbit.  The star's name is VV Cephei.

The sun spins at faster and slower rates at different lines of latitude.  This is the reason that the sun's magnetic fields are extremely chaotic and the reason for sunspots.  

Most stars in the universe are part of a binary system (two stars that orbit each other)

When two galaxies intersect and although there are hundreds of billions of stars in each galaxy, the distances between stars is so great that no two stars will collide with each other.  The galaxies will pass right through each other like ghosts until gravity takes hold again and the galaxies will dance around each other and eventually form one huge galaxy.  

Stars are formed in huge clouds of molecular hydrogen known as nebulae.

A stars color is directly related to it's surface temperature.  A red star has a cooler surface and a white star.  And a white star is cooler than a blue star.  

Answer 5

Take a course in stellar structure. You might need to take courses in differential equations and numerical analysis first. And some basic physics, especially thermodynamics, would help. Imagine how you'd blow away your science teacher if you could do all the math involved. You'd get an A for sure.

Some of the things Dee told  you are not true.

Answer 6

There is a ton of information out there.

Try http://www.worldwidetelescope.org/experi...   - which is like Google Earth, but for space, stars and alike. It's a application for your computer.

Answer 7

1-There are more stars than all of the grains of sand on earth.

2-You can see stars from the bottom of a well even in day light.

3-Stars with really strong gravity cause themselves to become smaller and smaller and eventually turn into black holes.

4-Stars come in different colors; hot stars give off blue light, and the cooler stars give off red light.

5-In honor of the original thirteen states, the U.S. $1 bill has the following on the back: 13 steps on the pyramid. The motto above the pyramid has 13 letters (annuity coatis). E pluribus Unum, written on the ribbon in the eagle's beak, has 13 letters. 13 stars appear over the eagle's head. 13 stripes are on the shield. 13 war arrows are in the eagle's left talon.

6-All of the stars comprising the Milky Way galaxy revolve around the center of the galaxy once every 200 million years or so.

7-Until the mid sixteenth century, Comets were believed to be not astronomical phenomena, but burning vapors that had arisen from distant swamps and were propelled across the sky by fire and light.

8-Our galaxy has approximately 250 billion stars and it is estimated by astronomers that there are 100 billion other galaxies in the universe.

9-A galaxy of typical size, about 100 billion suns produces less energy than a single Quasar.

10-A Comet's tail always points away from the sun.

11-A Pulsar is a small star made up of neutrons so densely packed together that if one the size of a silver dollar landed on earth, it would weigh approximately 100 million tons.

12-The Star Alpha Herculis is twenty five times larger than the circumference described by the earth's revolution around the sun. This means that twenty five diameters of our solar orbit would have to be placed end to end to equal the diameter of this Star.

13-Stars closer to the horizon appear to twinkle more than stars that are overhead - because the light of stars near the horizon has to travel through more air than the light of stars overhead and therefore subject to more refraction. Also, planets do not usually twinkle, because they are so close to us; they appear big enough that the twinkling is not noticeable (except when the air is extremely turbulent).

Stars would not appear to twinkle if we looked at them from outer space (or from a planet/moon that didn't have an atmosphere).
