E = hf E = hcT/b hf = hcT/b f = cT/b f = ((m/s)*K) / (mK) = 1/s = s^-1 = Hz B E=mc2 the Sun produces its energy by the conversion of matter into energy in its core E=mc2 Stars like the Sun live for around 10 billion years or more. but massive stars, die allot quicker because they burn massive amounts of nuclear fuel. Stars are giant nuclear reactors. In the center of stars, atoms are taken apart by allot of atomic collisions that change the atomic structure this then release allot of energy. This makes the stars’ super hot and bright.
Would we have an extreme runaway greenhouse effect and dry up like Venus? The concept of a habitable zone, sometimes referred to as the “Goldilocks Zone,” is vital to explaining the possibilities. WOULD MOVING EARTH CLOSER HAVE A BIG EFFECT? What would happen if Earth were to move a mile closer to the sun? Since the Earth’s orbit is an ellipse, not a circle, its distance from the sun varies from a minimum of 147.1 million kilometers each January to a maximum of about 152.1 million kilometers each July.
The moon has orbited the earth for over 4 billion years. Many scientists hold different opinions on how the moon was really formed. There are three main thoughts on how the moon was formed, these being:the giant impact theory, the co-formation theory and the capture theory. But the question still remains, how was the moon created? The giant impact theory, Space.com thinks that the giant impact theory is probably the most valid of the three,this theory holds the idea that the as earth orbited the sun in its early days it collided with many other smaller objects (asteroids) that were travelling through space at the time, and absorbed them into its growing mass.
Also, it is a dominant greenhouse gas which contribute to the global warming and climate change, the ability to trap thousands of times more heat than carbon dioxide. HFCs are categorized as a more long-term supersession than HCFCs, and have an ozone depleting potential of zero as they contain no chlorine and they are nonflammable. What negative effects will this factor have on your
They have almost the same density. They both come from the same part of the solar nebula. Differences: Venus has a slower rotation than Earth. Earth has a stronger magnetic field than Venus. Venus’s atmosphere is mostly made up of carbon dioxide, while Earth’s carbon dioxide density is lower.
It is the accumulation of iron in the center of a star which triggers a supernova explosion and the subsequent scattering of the vital atoms of life throughout the cosmos. It was the drawing by gravity of iron atoms to the center of the primeval earth that generated the heat which caused the initial chemical differentiation of the earth, the outgassing of the early atmosphere, and ultimately the formation of the hydrosphere. It is molten iron in the center of the earth which, acting like a gigantic dynamo, generates the earth’s magnetic field, which in turn creates the Van Allen radiation belts that shield the earth’s surface from destructive high-energy-penetrating cosmic radiation and preserve the crucial ozone layer from cosmic ray
For many years, it has been believed and scientifically proven that only the planet Earth can sustain life. And without it, we’ll no longer have a place to call home. However, with the Earth’s drastic condition - climate change, greenhouse gases, depletion of the ozone layer, and etc.- the astronomers have been searching for a planet that can save us from the ultimate fate of the Earth- and to also prove that we are not alone. Thus, after long years of research, we have found Kepler-452b. Here is a gist of what has been discovered about Kepler-452b: Kepler-425b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun.
The big bang was an enormous blast of energy throughout the universe, which formed all things instead the universe. Using Thomas’ logic of causes and effects in world, this massive explosion could have produced the first effects in the world since science does not have a theory to what caused the big bang, Thomas would state, whatever the cause of the big bang is an uncaused cause. This would be considered God, which God’s only effect could be the big bang theory in which that would create other effects and eventually over time into the world we
The spacecraft found out information about the moon and the rings around Uranus all of that in just 6 hours. It also discovered 10 new moons and that Uranus has got a stronger magnetic field then saturn. Uranus is called the ice giant because it is made up of frozen water (ice) methane and ammonia. Uranus can hit the coldest temperature of any planets in the solar system. Neptune is average more colder but Uranus can sometimes be really
Astronomers from WISE say that with the new infrared observations, Baptistina is not the responsible party leaving the Origin of the Asteroid a mystery to scientists. Immediate Impact on Earth The asteroid which collided with Earth 66 million years ago immediately created a deep hole, known as the peak ring, with an area of 100 kilometres wide and 30 kilometres deep, leaving the crater mainly under sea. Just after the impact deep granite bedrock, in liquid form, rebounded up to 10 kilometres tall before falling into a circular ridge. Next, the peak ring was enclosed in a layer of rocks, called a breccia, that contains bits of broken rock and impact melt. The Chicxulub asteroid originally landed near the town of Chicxulub which is where the asteroid got its name.
Starburst galaxies can sometimes be the brightest things in the universe. This happens when they release ultraviolet rays, which are absorbed by the dust and then re released at infrared wavelengths. The formation of stars can be stopped if the remaining gas in the galaxy is blown away by stellar winds or a Supernova explosion. Starburst galaxies are less common now than they were in the early stages of the universe. These galaxies are about 12 billion
Brown and barren, tortured by the extreme heat of the sun, this planet 's surface geology is limited. Venus 's atmosphere is extremely thick compared to the one surrounding our own planet. While Earth 's atmosphere works as a buffer, keeping the planet at just the right temperature, the atmosphere on Venus is so thick that it traps most of the heat from the sun, resulting in extreme temperature variations on the surface. Made of carbon dioxide, nitrogen,
The average temperature of an interstellar cloud are about 10 K. The density is about 1 Billion particles. These clouds are very stable. On the other hand if a star was to form within in an interstellar clouds the clouds need to become the opposite of stable, they need to become unstable and collapse not being able to handle its own gravity. When they collapse they create smaller clouds. Then they will break down and become unstable and so on and so forth.
The discovery was Pluto’s surfaces were new. Scientists have yet to determine why Pluto’s surfaces are new. That’s interesting because most planet are beat up by asteroids and meteor rocks throughout there exist. Could Pluto existence be from a large piece of another planet? Like most of the other planets, Pluto has several moons.
