Who discovered Sun?
GalileoCurious about the Sun, Galileo used his telescope to learn more.
Not knowing that looking at our very own star would damage his eyesight, Galileo pointed his telescope towards the Sun.
He discovered that the sun has sunspots, which appear to be dark in color..
How hot is the earth?
10,800 degrees FahrenheitIn new research, scientists studying what the conditions at the core should be like found that the center of the Earth is way hotter than we thought—around 1,800 degrees hotter, putting the temperature at a staggering 10,800 degrees Fahrenheit.
When was Adam and Eve born?
They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men’s mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.
What was before dinosaurs?
At the time all Earth’s land made up a single continent, Pangea. The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo.
Is the sun black?
The Sun, with an effective temperature of approximately 5800 K, is an approximate black body with an emission spectrum peaked in the central, yellow-green part of the visible spectrum, but with significant power in the ultraviolet as well.
What color is the hottest star?
Blue starsRed stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
How old is the earth?
4.543 billion yearsEarth/AgeEarth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
Who was the first human?
Homo habilisThe First Humans One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life.
Are all humans from Africa?
sapiens most likely developed in the Horn of Africa between 300,000 and 200,000 years ago. The “recent African origin” model proposes that all modern non-African populations are substantially descended from populations of H. sapiens that left Africa after that time.
What came after dinosaurs?
About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.
When did life first appear on Earth?
3.7 billion yearsThe earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
What’s the first animal on earth?
comb jellyThe evolutionary history of the comb jelly has revealed surprising clues about Earth’s first animal. Earth’s first animal was the ocean-drifting comb jelly, not the simple sponge, according to a new find that has shocked scientists who didn’t imagine the earliest critter could be so complex.
Where did the first human come from?
AfricaHumans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
What are the 3 human races?
The main human races are Caucasoid, Mongoloids (including Chinese, Japanese, Koreans, and American Indians, etc.), and Negroid. Khoisanoids or Capoids (Bushmen and Hottentots) and Pacific races (Australian aborigines, Polynesians, Melanesians, and Indonesians) may also be distinguished.
What Colour is Pluto?
Pluto’s visual apparent magnitude averages 15.1, brightening to 13.65 at perihelion. In other words, the planet has a range of colors, including pale sections of off-white and light blue, to streaks of yellow and subtle orange, to large patches of deep red.
What is God’s age?
I’d even say there was no God before the end of the Neolithic age, and that means God is roughly 7,000 years old. I was taught that it is bad form to ask a lady her age. If God is a woman, she is 39.
How long have humans existed?
about 200,000 yearsWhile our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago.
What are 5 interesting facts about Earth?

What color is the sun?
whiteThe color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination “white”. That is why we can see so many different colors in the natural world under the illumination of sunlight.
What is the most interesting fact?

Are Sharks older than dinosaurs?
As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees.
Will the Earth die?
However, the long-term trend is for plant life to die off altogether. … By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
