What is it like inside a nebula?
Nebulae are pretty only when they are hundreds of light-years away.
They look thick and cloudy only because you see the structures of light-years in thickness.
Once you’re close to them, their light spreads out so much that you can’t see them.
You could fly your spaceship right into the nebula and never even know it..
What is the biggest universe or 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 biggest known star?
Pistol StarAnswer: 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.
Which is the hottest star in the universe?
Eta CarinaeEta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
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.
What’s the heaviest thing on earth?
The heaviest object ever directly weighed was the Revolving Service Structure (RSS) of launch pad 39B at NASA’s Kennedy Space Center, Florida, USA. The structure was lifted up on 21 jacking points which, between them, measured the mass of the RSS as 2,423 tonnes (5,342,000 lbs).
What is a dying star called?
supernovaeSome types of stars expire with titanic explosions, called supernovae. When a star like the Sun dies, it casts its outer layers into space, leaving its hot, dense core to cool over the eons. But some other types of stars expire with titanic explosions, called supernovae.
What is bigger than a supercluster?
Celestial bodies bigger than the supercluster: A light year is the distance traveled by light in one year and is equivalent to 9.46 trillion kilometers.
What galaxy do we live in?
The Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way.
How old is our galaxy?
13.51 billion yearsMilky Way/Age
How many dead bodies are floating in space?
However, of the roughly 550 people who have so far ventured into space, only three have actually died there. Bringing the universe to your door.
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.
What is a dead star called?
A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently that it no longer emits significant heat or light.
What is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
Is a nebula bigger than a galaxy?
Simply put, the main difference between galaxies and nebulae are an extreme difference in size, as well as their basic structure. A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. A galaxy is much larger — usually thousands to hundreds of thousands of light years across.
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.
Which color star is the coolest?
redThe hottest stars tend to appear blue or blue-white, whereas the coolest stars are red. A color index of a star is the difference in the magnitudes measured at any two wavelengths and is one way that astronomers measure and express the temperature of stars.
Which universe do we live in?
We live on a planet called Earth that is part of our solar system. But where is our solar system? It’s a small part of the Milky Way Galaxy. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.
Which star shines the brightest?
Sirius ASirius 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.
