How big is the Milky Way galaxy in scientific notation?

How big is the Milky Way galaxy in scientific notation?

“In scientific notation, the diameter of the Milky Way is 1 10 21 m, and the diameter of the carbon nucleus is 1 10 14 m. The Milky Way is therefore approximately 10 35 times (35 orders of magnitude) larger than the carbon atom.”

How many stars are in the observable universe scientific notation?

“Using the Milky Way as our model, we can multiply the number of stars in a typical galaxy (100 billion) by the number of galaxies in the universe (2 trillion). The answer is an absolutely astounding number. There are approximately 200 billion trillion stars in the universe.”

Does the Milky Way have 200 billion stars?

““Earth is in the Milky Way galaxy. It’s home to over 200 billion stars with ours being the sun.” Not only is the Milky Way a huge accumulation of stars, but it holds planets, asteroids, meteors, comets and other solar remnants. Most stars are at the center of the galaxy with few at the outer edges.”

Is there anything bigger than Milky Way?

“The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!”

How large is the universe in scientific notation?

“The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m). Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22×104 Gpc3 (4.22×105 Gly3 or 3.57×1080 m3).”

What is the importance of 369?

“The number 369 is also a symbol of hope. This number is often seen as a reminder that no matter what challenges we face in life, we are never alone. The angels are always with us, guiding and protecting us. Trust that the Universe has your back and know that you will always be supported.”

What makes up 99.9 of the universe?

“”99.9 percent of the Universe is made up of plasma,” says Dr. Dennis Gallagher, a plasma physicist at NASA’s Marshall Space Flight Center. “Very little material in space is made of rock like the Earth.””

How many atoms are in the Milky Way?

“Our galaxy, the Milky Way, contains approximately 100 to 400 billion stars. If we take this as 200 billion or 2 × 1011 stars and assume that our sun is a reasonable average size we can calculate that our galaxy contains about (1.2 × 1056) × (2 × 1011) = 2.4 × 1067 atoms.”

How many stars are in the Milky Way 2022?

“Astronomers estimate there are about 100 thousand million stars in the Milky Way alone.”

Why can’t we see a 15 billion year old galaxy?

“Answer and Explanation: Because the universe is estimated to be less than 14 billion years old, conventional wisdom would indicate that we can’t see a galaxy 15 billion light-years away because, if anything exists 15 billion light-years away at all, its light hasn’t had enough time to reach us.”

What will the Milky Way look like in 1 trillion years?

“Our Milky Way will have lost its identity long ago through merging with the Andromeda galaxy, M31. The resulting giant elliptical galaxy will be devoid of dust and gas. The night sky will be a largely homogeneous sprinkling of stars. Stellar density will concentrate toward the galactic core.”

What is the heaviest galaxy?

“Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.”

What is the largest known star?

“The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.”

What is 75% of the universe made of?

“Hydrogen is the most abundant element in the universe, accounting for about 75 percent of its normal matter, and was created in the Big Bang. Helium is an element, usually in the form of a gas, that consists of a nucleus of two protons and two neutrons surrounded by two electrons.”

What is 90% of the universe made of?

“NEW YORK — All the stars, planets and galaxies that can be seen today make up just 4 percent of the universe. The other 96 percent is made of stuff astronomers can’t see, detect or even comprehend. These mysterious substances are called dark energy and dark matter.”

What is 85% of the universe made of?

“Dark matter makes up about 85 percent of the total matter in the universe, accounting for more than five times as much as all ordinary matter. Dark matter played an important role in the formation of galaxies.”

Is ton 618 bigger than IC 1101?

““The current heaviest black hole is associated with the quasar TON 618 and has a mass of 70 billion solar masses, while the second heaviest, at the center of the galaxy IC 1101, has a mass inferred from its radio emission of 40 billion solar masses.””

How do scientists estimate the size of a galaxy?

“Astronomers can use what are called surface brightness fluctuations (SBF, for short), along with the color of a galaxy, to calculate how far away it is from earth. Most galaxies measured in this way are millions of light years away.”

How big is IC 1101?

““

How far is the Andromeda galaxy in scientific notation?

“(2.5 x 106) x (6 x 1012) = 15 x 1018. Since 1018 is a “quintillion”, that’s fifteen “quintillion” miles. In scientific notation, we’d simplify it to 1.5 x 1019 miles.”
