How do stars look like exactly?
Stars come in colors from red, orange, yellow, white, bluish-white, and blue. The color depends on how hot the star is. A red star is the coolest, but still is about 5,000° Fahrenheit! Our sun is yellowish-white and the surface is about 10,000° Fahrenheit.
Has anyone seen a star up close?
An international team of astronomers has produced the first detailed image of the surface of a giant star – named Pi1 Gruis – that’s about 530 light-years from Earth in the constellation Grus (Latin for ‘crane’). …
What does a star look like when it dies?
How are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. … Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses, the material at the center begins to heat up.
Are galaxies close together?
I heard yesterday that relative to their size, galaxies are much closer together than stars. Just using orders of magnitude, the sun is 109 meters wide and the nearest star is 1016 meters away. … The Milky Way is 1021 meters wide, and the Andromeda galaxy is 1022 meters away.
Why do stars twinkle?
How old are the stars we see?
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.
Are stars suns or planets?
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
How long would it take for us to see a star explode?
Most supernova take a fraction of a second up to a couple seconds to explode. What we observe as the actual supernova is the light and energy that come out of that explosion. Typical supernova get brighter during the first 3 weeks or so after that very fast explosion.
Has any star gone supernova?
The most recent supernova to be seen in the Milky Way galaxy was SN 1604, which was observed on October 9, 1604. Several people, including Johannes van Heeck, noted the sudden appearance of this star, but it was Johannes Kepler who became noted for his systematic study of the object itself.
Do stars move?
Where do dead stars go?
What is a shooting star?
noun. rocky debris from space that enters Earth’s atmosphere. Also called a meteor.
Are stars alive?
Stars are not alive, and yet we speak of their origins and ends as “birth and death.” It’s a convenient, if fanciful, way of describing the ultimately ill-fated relationship between matter and energy that is a star.
Can a star turn into a planet?
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.
What happens to a star when it is a red giant?
Can the earth survive Andromeda collision?
What will happen if 2 galaxies collide?
When you’re wondering what happens when two galaxies collide, try not to think of objects smashing into each other or violent crashes. Instead, as galaxies collide, new stars are formed as gasses combine, both galaxies lose their shape, and the two galaxies create a new supergalaxy that is elliptical.
What happens if two black holes collide?
What is the hottest color of star?
How many stars are there?
How far away are stars?
The closest star is about 25,300,000,000,000 miles (39,900,000,000,000 kilometers) away, while the farthest stars are billions of times farther than that.
Do Dead stars still shine?
After a star dies, there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow, even though it is not producing any energy. Eventually, the star cools off and does indeed simply become a hunk of ash, which we call a “black dwarf.”
How long does it take for the light from a star to reach Earth?
|Object||Time for the Light to Reach Us|
|Alpha Centauri (nearest star system)||4.3 years|
|Sirius (brightest star in our sky)||9 years|
|Betelgeuse (bright star)||430 years|
|Orion Nebula||1500 years|
Are we made of stardust?
Is the star bigger than the Earth?
How old is the Earth?

What is the largest star in the universe?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.Jul 25, 2018
What if the Sun exploded?
Can we see supernova from Earth?
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.
What supernova will happen in 2022?
This is exciting space news and worth sharing with more sky watch enthusiasts. 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.
