Can All stars make elements of all sizes?
Only the bigger stars can produce heavier elements. This is because these stars can pull up their temperatures higher than the smaller stars like our Sun can.
Where did all elements come from?
the universe formed through the big bang explosion, all of the elements on Earth have been cooked for billions of years in stars and then released in the universe through super- nova explosions.
How many elements do stars create?
As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies. The other 86 elements found in nature were created in nuclear reactions in these stars and in huge stellar explosions known as supernovae.
Is a supernova bigger than a galaxy?
Supernovae can briefly outshine entire galaxies and radiate more energy than our sun will in its entire lifetime. They’re also the primary source of heavy elements in the universe. According to NASA, supernovae are “the largest explosion that takes place in space.”
Can we create new elements?
New elements aren’t exactly discovered anymore. However, they can be made, using particle accelerators and nuclear reactions. A new element is made by adding a proton (or more than one) or neutron to a pre-existing element.
Does atom really exist?
Atoms and Molecules exist in nature due to the fact that matter is made up of small particles called atoms.
Can All stars produce heavy elements?
Every element possible, that is, except the three we skipped. You see, the Universe starts off with hydrogen and helium, all stars produce helium, and then stars over a certain mass threshold produce carbon, nitrogen, oxygen and lots of heavier elements.
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
What’s the rarest element in the universe?
Element Astatine.
The rarest naturally occurring element in the universe. Discovered in 1940.
Do stars create elements?
Light elements like hydrogen and helium formed during the big bang, and those up to iron are made by fusion in the cores of stars. Some heavier elements like gallium and bromine need something more, such as a supernova.
Will there be a supernova in 2022?
Yes, it is true that somewhere there is likely to be a supernova during 2022. It is likely to be in another galaxy. Supernova that are visible to the naked eye on Earth occur, on average, once every 200–400 years. The most recent one was supernova 1987a.
Will a supernova destroy Earth?
A supernova is a spectacular explosion of a massive star. If our sun exploded as a supernova, the resulting shock wave probably wouldn’t incinerate the entire Earth, but the side of Earth facing the sun would boil away.
How are stars born?
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
What’s the gravity of a black hole?
The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now. The sun will never turn into a black hole.
Is it true that the average star has shorter lifespan?
A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion.
When a star becomes a red giant it will?
Once at the red giant stage, a star might stay that way for up to a billion years. Then the star will slowly contract and cool to become a white dwarf: Earth-sized, ultra-dense star corpses radiating a tiny fraction of their original energy.
Why do stars stop at iron?
The outer regions of the star have expanded to fill a volume as large as Jupiter’s orbit from the Sun. Since iron does not act as a fuel, the burning stops. The sudden stoppage of energy generation causes the core to collapse and the outer layers of the star to fall onto the core.

How are atoms created?
Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
What is Democritus atomic theory?
The atomic philosophy of the early Greeks
Democritus believed that atoms were uniform, solid, hard, incompressible, and indestructible and that they moved in infinite numbers through empty space until stopped. Differences in atomic shape and size determined the various properties of matter.
How did Albert Einstein prove the existence of atoms?
In 1827, the English botanist Robert Brown noticed that pollen seeds suspended in water moved in an irregular “swarming” motion. Einstein then reasoned that if tiny but visible particles were suspended in a liquid, the invisible atoms in the liquid would bombard the suspended particles and cause them to jiggle.
How long do stars live for?
Stars live different lengths of time, depending on how big they are. A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long.
What is the closest star to Earth?
The closest star to Earth is a triple-star system called Alpha Centauri. The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are about 4.35 light-years from Earth, according to NASA.
How old are the stars we see today?
For the most part, the stars you see with the naked eye (that is, without a telescope) are still alive. These stars are usually no more than about 10,000 light years away, so the light we see left them about 10,000 years ago.
What is the hardest element to get?
Can you name the hardest element? It’s an element that occurs naturally in pure form and has a hardness of 10 on the Mohs scale. Chances are you have seen it. The hardest pure element is carbon in the form of a diamond.
What is the heaviest element?
There are 91 naturally occurring elements (but it depends on how you count them). The heaviest element that occurs in large quantity is uranium (atomic number 92).
Are all stars made of hydrogen?
Hydrogen and helium are found in all stars. Ninety percent of all atoms in the universe are hydrogen atoms and fusion reactions fuel stars, resulting in the formation of helium and higher atomic number elements.
What is the oldest thing in the universe?
Microscopic grains of dead stars are the oldest known material on the planet — older than the moon, Earth and the solar system itself. By examining chemical clues in a meteorite’s mineral dust, researchers have determined the most ancient grains are 7 billion years old — about half as old as the universe.
What’s the hardest thing in the universe?
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
Why do you think massive star?
A massive star has a shorter life span than an average star because of faster hydrogen fuel consumption by a massive star. Massive stars have shorter lives than common small stars because, despite having more hydrogen for nuclear reactions, they consume their fuel at a much faster pace because of their very large size.
Can a star turn into a planet?
Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. Some scientists do not consider brown dwarfs to be true stars because they do not have enough mass to ignite the nuclear fusion of ordinary hydrogen.
What does a star turn into when it dies?
After puffing off its outer layers, the star collapses to form a very dense white dwarf. One teaspoon of material from a white dwarf would weigh up to 100 tonnes. Over billions of years, the white dwarf cools and becomes invisible.
How many galaxies are there?
All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.
What would happen if the sun exploded?
The Sun will get hotter and brighter, and it will start to expand. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
Will I see a supernova in my lifetime?
Unfortunately, supernovae visible to the naked eye are rare. One occurs in our galaxy every few hundred years, so there is no guarantee you will ever see one in our galaxy in your lifetime. In 1987, a supernova called 1987A was visible in a nearby galaxy called the Large Magellanic Cloud.
Is there a star that will explode in 2022?
In 2022—only a few years from now—an odd type of exploding star called a red nova will appear in our skies in 2022. This will be the first naked eye nova in decades. And the mechanism behind it is fascinating as well.
Will 2 stars collide in 2022?
According to study from a team of researchers from Calvin College in Grand Rapids, Michigan, a binary star system that will likely merge and explode in 2022. This is an historic find, since it will allow astronomers to witness a stellar merger and explosion for the first time in history.
Is it possible for the earth to explode?
Fortunately, that’s unlikely to happen anytime soon. Based on the geological record of cosmic impacts, Earth gets hit by a large asteroid roughly every 100 million years, according to NASA. However, smaller asteroid impacts do happen all the time.
When did the Earth explode?
ATLANTA—A cataclysm may have jump-started life on Earth. A new scenario suggests that some 4.47 billion years ago—a mere 60 million years after Earth took shape and 40 million years after the moon formed—a moon-size object sideswiped Earth and exploded into an orbiting cloud of molten iron and other debris.
What is inside a white hole?
In general relativity, a white hole is a theoretical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it.
Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
Are we inside a black hole?
We might be the product of another, older universe. Call it our mother universe. The seed this mother universe forged inside a black hole may have had its big bounce 13.8 billion years ago, and even though our universe has been rapidly expanding ever since, we could still be hidden behind a black hole’s event horizon.
What do red giants fuse?
Once the helium core reaches 100 million degrees, it explosively begins fusing helium. The birth of the active helium core is called the helium flash. The Sun as a red giant will fuse helium for about 2 billion years after the helium flash.
Why do some stars become super red giant?
The fusion of hydrogen to form helium changes the interior composition of a star, which in turn results in changes in its temperature, luminosity, and radius. Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants.
How do stars burn out?
The “burn-out” happens through a phenomenon called nuclear fusion. Nuclear fusion happens when the atoms inside the star collide together (often the element hydrogen). Fusion usually turns hydrogen into helium–going “up” the periodic table, so to speak.
Will the Sun become a black hole?
No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
How long before our sun dies?
According to a study in the journal Nature Astronomy earlier this year, the Sun will ‘die’ in about 10 billion years. Stars, like the Sun, start to ‘die’ when they’ve burnt all of their hydrogen fuel. At this point, they expand and become a very large kind of star called a red giant.
Will the Sun swallow the Earth?
The Sun would be larger than Earth’s orbit. It would swallow the planet whole. Once it’s inside the Sun’s atmosphere, Earth would collide with particles of gas and spiral inward.
Can you drown a star?
As long as there’s still viable fuel at the core of the star, and adequate temperatures and pressures, it’ll continue fusing and releasing energy. If you could swap out the hydrogen in the sun with a core of iron, you would indeed kill it dead, or any star for that matter. It wouldn’t explode, though.
Can stars burn helium?
As a star burns hydrogen (H) into helium (He), the internal chemical composition changes and this affects the structure and physical appearance of the star. The older the star, the greater the amount of helium in the core.
Can we touch a star?
Surprisingly, yes, for some of them. Small, old stars can be at room temperature ex: WISE 1828+2650, so you could touch the surface without getting burned. Any star you can see in the sky with the naked eye, however, would be hot enough to destroy your body instantaneously if you came anywhere near them.
Is element 140 possible?
However, extended periodic table theories predicted about chemical elements beyond these 118 elements. According to this, Corbomite (Ct) is a chemical element with atomic number 140. However, in real-life science, element 140 has yet to be identified.
