Amazing Facts About *STARS*

• The Sun is the closest star. Located a mere 150 million km away from earth.

• Every star you see in the night sky is bigger and brighter than our sun. that is the reason you can see them.

• There are many, many stars, appox. 400 billion stars in our galaxy and there could be as many as 500 billion galaxies in the Universe, and each of which could have as many or more stars as our galaxy.

• They are very far from us. If you tried to hitch a ride on the fastest spacecraft ever launched from Earth, it would still take you more than 70,000 years to get there from earth.

• They are very massive. Some stars that are 100 times more massive than our Sun. These stars also can output about a million times more energy than our sun, while still maintaining the same radius.

• Eta Carinae is one of the largest stars in the known galaxy, it is designated as a hyper-giant.

• Another hyper-giant star is designated as Pistol, it shines even brighter than Eta Carinae, at about 10 billion times more than our sun. It emits such high amounts of radiation that scientists have already declared it impossible for anything to live in such a system.

• The color of a star can tell an observer a lot of things, as the color of a star can show give an idea of how much mass it has, luminosity and other interesting data.

• The coolest stars in the universe are red, and they sit at around 3,500 kelvin (a special temperature measurement used for stars).

• Opposite to that, the hottest stars are blue due to their incredible mass and the amount of chemical reactions occurring within them. They burn at around 6,000 kelvin.

• The stars that have the shortest life spans are the most massive. They lend their mass to a high density of chemicals; as such they burn their fuel much quicker than smaller stars.

• Stars don’t twinkle (twinkle-twinkle little star is not twinkling and not little also). As the light from a star passes through the atmosphere, especially when the star appears near the horizon, it must pass through many layers of often rapidly differing density. This has the effect of deflecting the light slightly as it were a ball in a pinball machine. The light eventually gets to your eyes, but every deflection causes it to change slightly in color and intensity. The result is “twinkling.” Above the Earth’s atmosphere, stars do not twinkle.

Amazing Facts About Dreams!!!

1. You cannot snore and dream at the same time.

2. Not everyone can dream in color.

3. Your body burns more calories sleeping than it does in the day time.

4. You can not control your dreams.

5. Just like men, women can have orgasms during dreams.

6. By the time we die, most of us will have spent a quarter of a century asleep, of which 6 years or more will have been spent dreaming and almost all of those dreams are forgotten (almost 90%) upon waking.

7. The average person has about 1,460 dreams a year. That’s about four per night.

8. Modern research has shown that a sharp decrease in daily calories results in fewer nocturnal ejaculations in men and an overall decrease in the sexual themes of dreams.

9. Aside from those who experience certain kinds of injury, it’s a biological fact that everyone dreams. However, not everyone remembers his or her dreams.

10. Most of us dream every 90 minutes, and the longest dreams (30-45 minutes) occur in the morning.

11. The memory-recording processes of the brain seem to switch off during sleep. In so-called non-dreamers, this memory shutdown is more complete than it is for the rest. Dreams may be forgotten because they are incoherent or because they contain repressed material that the conscious mind does not wish to remember.

12. In general, pregnant women remember dreams more than other populations. This is largely due to the extreme hormonal changes during pregnancy.

13. Birth order influences the role of aggression in dreams. While men typically experience more aggressive dreams than women, a firstborn male typically sees himself in a more positive manner than do his younger male siblings. First-born females tend to have more aggressive characters in their dreams.

14. Modern studies show that children have more animal dreams than adults. The animal figures that occurred most frequently are dogs, horses, cats, snakes, bears, lions, and mythical creatures or monsters.

15. Childhood dreams are shorter than adult dreams and nearly 40% of them are nightmares, which may act as a coping mechanism.

16. People who are born blind report no visual imagery in dreams, but they experience a heightened sense of taste, touch, and smell. Those who become sightless between the ages of five and seven may have visual images in their dreams, while those who lose their vision after age seven continue to “see” in their dreams, though images tend to fade as they grow older.

17. Men’s dreams are more often set outdoors, are more action oriented, and involve strangers more often than women’s dreams do. Women’s dreams usually happen indoors and involve emotional encounters with people they know and care about. Men are more likely than women to dream about aggression, misfortune, and negative emotions such as fear, anger, anxiety, or disgust. Women’s dreams are more often friendly and positive.

18. For reasons that are unknown, males dream of males more often than females dream of males. This sexual asymmetry is universal and has emerged from at least 29 different comparisons of male and female dreams-and it holds true for children, adolescents, and adults in all parts of the world.
