Supernovae can briefly outshine entire galaxies and radiate more energy than our sun will in its entire lifetime. They’re also the primary source of heavy elements in the universe. According to NASA, supernovae are “the largest explosion that takes place in space.”
What is the biggest explosion in space?
The news: Astronomers have detected the biggest explosion in space that’s ever been observed. The massive eruption occurred in the Ophiuchus cluster, about 390 million light-years from Earth, where thousands of individual galaxies mingle with hot gas and dark matter.
What is the biggest explosion in the galaxy?
The biggest cosmic explosion on record has been detected – an event so powerful that it punched a dent the size of 15 Milky Ways in the surrounding space. The eruption is thought to have originated at a supermassive black hole in the Ophiuchus galaxy cluster, which is about 390m light years from Earth.
What is the biggest explosion that humans have ever seen?
A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
What explodes in space?
Yes, provided there is an oxidizer. A spaceship with liquid hydrogen and liquid oxygen will blow up quite well in the vacuum of space. … Nuclear explosions can of course occur in space, too. However, in space, there is no atmosphere to transmit sound from the explosion to the observer, so it would appear to be silent.
Can a bomb explode in space?
If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. … There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.
What is the most powerful explosion in the universe?
GRB 080916C is a gamma-ray burst (GRB) that was recorded on September 16, 2008 in the Carina constellation and detected by NASA’s Fermi Gamma-ray Space Telescope. It is the most powerful gamma-ray burst ever recorded.
Can you see an explosion in space?
To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so we would not be able to hear the explosion.
What is the biggest thing in our 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.
Will universe ever explode?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Can a supernova destroy a planet?
Yes, absolutely. A supernova would annihilate anything within its blast zone. A that includes really big planets.
Can our sun go supernova?
A supernova — specifically, a core-collapse supernova — can only occur when a star many times more massive than our Sun runs out of nuclear fuel to burn in its core. … When our Sun runs out of hydrogen fuel in the core, it will contract and heat up to a sufficient degree that helium fusion can begin.
Do stars explode?
Such stars explode when they use up their nuclear fuel and collapse. Stars weighing more than about eight times the Sun’s mass burn through their hydrogen fuel quickly, but as a massive star runs low on one fuel, it taps into another. … Each new fuel releases less energy, so the star burns through it even faster.
What happens if we nuke the moon?
The explosion would also likely create a shotgun-like blast of moon debris, as lower gravity makes it easier for moon rocks and dust to easily escape the moon’s gravity. This would be ejected into space, but also strike Earth, creating micrometeor showers visible in the night sky.
Are there nuclear weapons in space?
The United States, Russia, China and India have shown such capability, with the U.S. and Russia having performed nuclear tests in space in the 1960s. Russia tested such a capability as recently as April.
How much do astronauts make in space?
According to NASA, here are the common salaries for astronauts and how they are categorized: GS-11 astronauts average starting salary: $66,026 per year. GS-14 astronauts can earn up to $144,566 per year.
