Is the flag still on the moon?
Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing..
Can Earth survive a black hole?
Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in.
What would happen if the moon was hit by a large asteroid?
If the 400-meter-wide asteroid were to impact the moon, it would kick up enough dust — and that dust would moving at a high enough speed — for a small quantity to escape the moon’s gravity and coast all the way to Earth, 240,000 miles away, Yeomans said.
Can we survive without moon?
The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Can you survive an asteroid?
Yes, We Can Survive A Deadly Asteroid Impact Just As Our Early Ancestors Did. This article is more than 2 years old. There is new evidence that our early ancestors survived a kilometer-sized asteroid impact in Southeast Asia.
Will the Earth die?
Four billion years from now, the increase in the Earth’s surface temperature will cause a runaway greenhouse effect, heating the surface enough to melt it. By that point, all life on the Earth will be extinct.
How long the sun will last?
Stars like our Sun burn for about nine or 10 billion years. So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go.
What happen if the sun died?
It means our sun will run out of fuel in its interior. It’ll cease the internal thermonuclear reactions that enable stars to shine. It’ll swell into a red giant, whose outer layers will engulf Mercury and Venus and likely reach the Earth. Life on Earth will end.
What would happen if the moon was destroyed?
Destroying the Moon would send debris to Earth, but it might not be life-exterminating. … If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
What would happen if Earth was hit by an asteroid?
With an asteroid hitting the Earth; dust and smoke rising in the atmosphere prevents sunlight from reaching our world and causes the total temperature to drop. This event can lead to the death of many living things. If an asteroid the size of an apartment hits Earth, this blow could possibly destroy a small city.
Can an asteroid move the moon?
“If an asteroid hits the moon, it will just get another crater,” says Gareth Wynn-Williams, an astronomer at the University of Hawaii. It would take a moon-size object to move the moon, says Clark Chapman, a planetary scientist at the Southwest Research Institute, and most likely the moon wouldn’t survive.
Can we live without sun?
Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth’s position in the solar system is optimal for the development of life.
What if Earth stopped spinning?
If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. … This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.
What would happen if the moon hit Earth?
A large explosion might cause the debris to scatter away from the Earth, or the debris would fall towards us and create meteors that could hit the surface of our planet. An explosion with a specific amount of power might create a set of rings around our planet, like Saturn.
Can we stop an asteroid?
The impact of a massive object, such as a spacecraft or even another near-Earth object, is another possible solution to a pending NEO impact. An object with a high mass close to the Earth could be sent out into a collision course with the asteroid, knocking it off course.
Do asteroids hit the sun?
No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.
Could an asteroid hit Earth again?
As of October 2019, there were two asteroids with a more notable cumulative Palermo Technical Impact Hazard Scale than Apophis, though none of them have a Torino level greater than 0. On average, an asteroid the size of Apophis (370 metres) can be expected to impact Earth once in about 80,000 years.
What would happen if an asteroid hit Mars?
“An impact would loft a lot of stuff into the Martian atmosphere–dust, sand, water and other debris. The result could be a warmer, wetter Mars than we’re accustomed to today.” Meyer worries that solar-powered Opportunity might have a hard time surviving if the atmosphere became opaque.
How big was the explosion that killed the dinosaurs?
An instant later, the asteroid slams into Earth with an explosive yield estimated at over 100 trillion tons of TNT. The impact penetrates Earth’s crust to a depth of several miles, gouging a crater more than 115 miles (185 kilometers) across and vaporizing thousands of cubic miles of rock.
How long would we live if the sun died?
A relatively simple calculation would show that the Earth’s surface temperature would drop by a factor of two about every two months if the Sun were shut off. The current mean temperature of the Earth’s surface is about 300 Kelvin (K). This means in two months the temperature would drop to 150K, and 75K in four months.
How long would humans survive if the sun disappeared?
You might be able to survive for a bit longer than you think. If the sun suddenly blinked out of existence, you’d have nothing to worry about — for the first eight minutes, anyway. After that, all hell would likely break loose. Still, it wouldn’t be the instantaneous end to life on Earth that you might think.
