I was just this little kid made of hydrogen and helium. I hadn 't yet developed the right powers to turn this hydrogen and helium into energy for anyone. I felt alone and useless. But over the course of the next 50 million years as this protostar, the temperature and pressure inside me kept increasing, and finally I got my superpowers when I was able to convert hydrogen into helium through the process of nuclear fusion. Through fusion, I am able to create the necessary amount of heat to keep you folks alive.
preexisted as different forms. Evolution tries to show that everything evolved from something that existed a couple of billion or million years ago in a process called natural selection meaning that living things tend to evolve to another form to adapt and survive. It also tries to prove the Earth existing up to 4.5 billion years, meanwhile Scientist has proven that it is impossible for the Earth to be a billion years because the Earth’s magnetic field during the 18th century deteriorated in a predictable curve. With the results this shows that it is impossible to have life before 20000 B.C. An illustration showed that the moon would slowly be drifting away from the Earth.
The Earth has been in existence for over four billion years, and the universe for much longer, but modern humans have only existed for approximately two-hundred thousand years. Since the beginning of human thought, people have looked to the sky and wondered what lay beyond what we can see. With the advancement of the human mind along with technology, the perception of the cosmos has drastically changed over time. One of the most important changes in our thinking was the Copernican Revolution, when Copernicus aimed to replace Ptolemy’s earth-centred model of the solar system with a sun-centred one. The advancement of science facilitated the changes in our perception, and it can be argued that our knowledge about the universe is getting closer
The different gravitational pulls of the four types of stars show the different effects on space-time. The first star is our star in th center of the solar system referred to as the sun. The last star is a neutron star. Neutron stars are extremely dense star with a gravitational pull of two hundred billion times that of Earth. If a person lived on the sun in the center of our solar systems, and then traveled to a neutron star and lived there for one year, when the person went back to the sun he left, hundreds of years would have passed.
Close to its moon Triton, Neptune’s has an approximate surface temperature of -210° C and although it has a considerable distance and low power input from the Sun, Neptune has an incredibly active climate. On Neptune, winds are recorded to reach up to 1,500 miles an hour, three times stronger than Jupiter’s and nine times stronger than Earth’s currently making it the fastest terrestrial winds found in our solar system. To complement this, Neptune has two particularly intense storms ordinarily noted as the Great Dark Spot and the Small Dark Spot. The Great Dark Spot was said to be approximately the same size as Earth while the Small Dark Spot (also known as the Dark Spot 2 and the Wizards Eye) was roughly known to be the size of Earth’s moon. These Dark Spots on Neptune are quite similar to the Great Red Spot on Jupiter and usually compared to one another.
A subject of debate for years, centuries even, has been that of Creation versus Evolution. Which one outweighs the other? Which is most heavily supported by scientific evidence? Many have mulled over the idea of One omnipotent God miraculously creating the world we live in today, modeling it according to His perfect plan. Others stand firm in the belief of a phenomena of space and matter where earth was brought into existence by a spectacular “big bang,” causing entire planets, ecosystems, and life forms to materialize from nothing.
“The total mass of all eight planets is around 2.67 x 1027 kg. The sun 's mass is 1.989×1030 kilograms (2.2×1026 short tons), approximately 330,000 times the mass of Earth. It accounts for about 99.86% of the total mass of the Solar System.” (space.com). In this situation, the sun has a lot greater mass than all the planets, so it can carry the planets’ force, so it doesn’t move. This shows that the magnitude of the planets in the orbit around the
It is a gas giant, 96% of its volume is hydrogen. Saturn has been known since prehistoric times. Greek god Saturn was named after the planet, and ancient Chinese and Japanese culture named Saturn the “earth star”, one of the five elements of nature. Observations of Saturn from a telescope was first discovered by Galileo in 1610, with a 15mm diameter telescope. First photograph of the planet was in September 1979, by Pioneer 11, launched by NASA.
The Fission Theory is a commonly believed theory for how the Moon was created. This theory states that the Moon was once part of the Earth, but somehow separated from it. This is believed to have happened in early history times of the solar system. It is believed that the Moon most likely broke off of the Pacific Ocean basin. This is because the Moon 's composition is the same as the Earth 's.
An exoplanet is a planet that orbits a star not within our solar system. Formation of an exoplanet Before an exoplanet is formed, a star must be formed. The very beginning of the formation of a star begins with a gas and dust cloud, known as a molecular cloud which is a kind of nebula. The molecular cloud is mostly made up of hydrogen and helium gas. As the elements begin to clump together, the gravity of the clumps grow.
Freeman et al. (1977) measured a half-width of at least 32 arcmin x 15 arcmin for the HI extent of Circinus, much larger than the optical diameter (about 10 arcmin) of the galaxy. Jones et al. (1996, in prep.) and Koribalski & Whiteoak (1996) only recently mapped Circinus with several configurations of the ATCA; a few preliminary results are presented
Mercury is an amazing planet in our solar system. It is the smallest, fastest and closest planet out of the eight planets. It is a terrestrial planet slightly larger than the Earth’s moon. What is Mercury named after? Mercury is named after the messenger of the Roman gods Mercury.
Pluto’s curiosity since 1931 has grown and now this probe will answer a lot of questions that still known to us. The excitement builds as the probe reaches its destination. Will finally have the answers to questions we have waiting for? What I know from my research that Pluto has a lot of substance things I did not know about until now. Pluto has huge mountains and I know from the probe is remains the smallest planet in the s system.
There are exactly 7 steps for a star to become a main sequence star just like our Sun. Step one: Interstellar Clouds: This is the very first stage of the processing of a star forming into a main sequence star. It is known as a dense interstellar cloud. It could be the very core of a dark dust cloud even. Or sometimes a molecular cloud.
