Can you hear a star explode?
They’re so far apart though, the particles don’t immediately collide with each other allowing a sound wave to pass through a grouping of them.
So, even if you did watch the Death Star explode, you couldn’t hear it.
There’s no sound in space, so you can’t hear what a supernova sounds like..
How often does a star explode?
On average, a supernova will occur about once every 50 years in a galaxy the size of the Milky Way. Put another way, a star explodes every second or so somewhere in the universe, and some of those aren’t too far from Earth.
Do Stars make sounds?
Stars make sounds naturally but we can’t hear this as it is has to travel through space. “Like a musical instrument, stars are not uniformly solid all the way to their core, so the sound gets trapped inside the outer layers and oscillates around inside. “This makes the star vibrate causing it to expand and contract.
What would a supernova explosion look like from Earth?
Supernova Seen From Earth Life on Earth will be unharmed. But that doesn’t mean it will go unnoticed. Goldberg and Bauer found that when Betelgeuse explodes, it will shine as bright as the half-moon — nine times fainter than the full moon — for more than three months.
Will two stars collide in 2022?
Scientists predict that a pair of stars in the constellation Cygnus will collide in 2022, give or take a year, creating an explosion in the night sky so bright that it will be visible to the naked eye. If it happens, it would be the first time such an event was predicted by scientists.
When was the last time a star exploded?
October 9, 1604The most recent supernova to be seen in the Milky Way galaxy was SN 1604, which was observed on October 9, 1604.
Does the sun make noise?
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!
Can a star destroy Earth?
A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs (30 to 1000 light-years) away) to have noticeable effects on Earth’s biosphere.
What does an exploding star sound like?
Bang! Sounds—which are simply pressure variations in a medium such as air or water—can’t propagate in the vacuum of space, so the roiling surface of a star would make an impression on the eyes, but not the ears. A supernova would sound like 10 octillion two-megaton nuclear bombs exploding.
What would happen if a star exploded?
An explosion of a nearby star might leave Earth and its surface and ocean life relatively intact. But any relatively nearby explosion would still shower us with gamma rays and other high-energy radiation. This radiation could cause mutations in earthly life.
How loud would a supernova be?
Originally Answered: How loud is a supernova explosion? Zero Decibels. … But once this audio blast moves out into the vacuum of space, where there is nothing to pass the sound waves along, the sound would die out. If Sol exploded (which it in reality won’t), we would hear nothing from the star itself.
Does an explosion in space make a sound?
So it’s not strictly true that no sound vibrations can travel through space at all, but it is true that humans would not be able to hear any sounds in space. But in movies when they show a large space ship exploding and another spaceship nearby they often play a large exploding sound.
How loud is the sun if we could hear it?
How loud would the sun be measured on Earth if its soundwaves could propagate through space? The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth!
What is a dying star called?
Some 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.
How does a star fall on its own?
In collapsed stars, matter has been pushed to the limit. Internal pressures produced by nuclear power production in the centers of stars are no longer important, because the nuclear fuel has been exhausted. … When those nuclear reactions stop producing energy, the pressure drops and the star falls in on itself.
What is the loudest thing in the universe?
As far as I’m aware, the Perseus galaxy cluster is the current record holder for the loudest sound discovered in the Universe. Generating sound requires two conditions. First, there must be a medium that the sound waves can travel through, like air or some other gas.
How loud is a black hole?
1100 dB is the volume level at which the shockwave compresses the air to a density sufficient to make micro black holes the size of a neutron. 724 dB is the volume level of a shockwave which compresses air to a compact mass of neutrons, with density the same as a neutron star.
Can a supernova destroy a planet?
According to the model, when stars at least 7 to 10 times the mass of our sun go supernova, the blast swallows any inner planets, those orbiting out to several times the distance between Earth and the sun. (See “Red Giant Sun May Not Destroy Earth.”)
