What is biggest star in our galaxy?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star.
It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright.
In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy..
What are the 4 types of black holes?
And anything that ventures too close—be it star, planet, or spacecraft—will be stretched and compressed like putty in a theoretical process aptly known as spaghettification. There are four types of black holes: stellar, intermediate, supermassive, and miniature.
What is in a black hole?
A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.
Does the Galaxy have an end?
And now, NASA scientists say they know exactly when it will come to an end. In a universe that is forever spreading apart, the Milky Way has been moving closer to celestial neighbor the Andromeda galaxy.
Is it possible to travel to another galaxy?
According to the current understanding of physics, an object within space-time cannot exceed the speed of light, which means an attempt to travel to any other galaxy would be a journey of millions of earth years via conventional flight.
What is the next closest galaxy?
Distance Information The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
How many galaxies are they?
Research released in 2016 revised the number of galaxies in the observable universe from a previous estimate of 200 billion (2×1011) to a suggested two trillion (2×1012) or more and, overall, as many as an estimated 1×1024 stars (more stars than all the grains of sand on planet Earth).
What galaxy do we live in?
The Milky WayThe Milky Way. We live in one of the arms of a large spiral galaxy called the Milky Way.
What is beyond outerspace?
If by outer space you mean all that surrounds the Earth and stretches into all directions as far as people can see, then you’re talking about what astrophysicists call the universe. For there to be anything outside of the universe supposes that it has an edge, which is a problematic supposition for physicists.
Who is the creator of universe?
In other versions of creation, the creator deity is the one who is equivalent to the Brahman, the metaphysical reality in Hinduism. In Vaishnavism, Vishnu creates Brahma and orders him to order the rest of universe. In Shaivism, Shiva may be treated as the creator.
How old is our galaxy?
13.51 billion yearsMilky Way/AgeHow Old Are Galaxies? Most galaxies are between 10 billion and 13.6 billion years old. Our universe is about 13.8 billion years old, so most galaxies formed when the universe was quite young! Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old.
How many universes are there?
The multiverse. If we define “universe” as “all there is” or “all that exists,” then obviously, by definition, there can be only one universe. But if we define “universe” as “all we can ever see” (no matter how large our telescopes) or “space-time regions that expand together,” then many universes may indeed exist.
How many galaxies are in space?
100 billion galaxiesAll 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 is a galaxy for kids?
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system.
What is the name of Earth’s home galaxy?
The Milky WayThe Milky Way: Earth’s home galaxy. Giant clouds of gas and dust sprinkled with splashy star clusters adorn the Milky Way’s spiral arms, while the galaxy’s vast halo teems with darker matter. Scientists think our galaxy has four major spiral arms that wind their way out from a central bar.
What is the name of our universe?
Milky WayOver the next decades, the current terminology came in to use, with Milky Way as the name of our galaxy, the term Galaxy for all galaxies (groupings of billions of stars gravitationally bound), and Universe for everything.
Who created God?
Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
Which is bigger sun or star?
Although the Sun appears larger to us than any other star, there are many stars which are much larger. The Sun appears so large compared to the other stars because it is so much closer to us than any other star. The Sun is just an average sized star.
Which star shines the brightest?
Sirius A and B. The brightest star in the sky is Sirius, also known as the “Dog Star” or, more officially, Alpha Canis Majoris, for its position in the constellation Canis Major. Sirius is a binary star dominated by a luminous main sequence star, Sirius A, with an apparent magnitude of -1.46.
What is the oldest thing in the galaxy?
GN-z11 is currently the oldest and most distant known galaxy in the observable universe. GN-z11 has a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
What is the largest known star?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
What is the oldest thing in the universe?
Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
Which is the oldest star?
Methuselah starThis Digitized Sky Survey image shows the oldest star with a well-determined age in our galaxy. Called the Methuselah star, HD 140283 is 190.1 light-years away. Astronomers refined the star’s age to about 14.3 billion years (which is older than the universe), plus or minus 800 million years.
Where are we in our galaxy?
We’re about 26,000 light-years from the center of the galaxy, on the inner edge of the Orion-Cygnus Arm. It’s sandwiched by two primary spiral arms, the Sagittarius and Perseus Arms. The artists’ concepts above and below show the Orion-Cygnus Arm, the home spiral arm of our sun in the Milky Way galaxy.
What are the 4 types of galaxies?
In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies. More than two-thirds of all observed galaxies are spiral galaxies.
What is the youngest galaxy?
Dubbed Abell2744_Y1, the galaxy is so far away that it takes about 13 billion years for light from the galaxy to reach our neighborhood. That means it appears as it was just 650 million years after the Big Bang, scientists say. The universe is estimated to be about 13.8 billion years old.
