If Hubble looked at the Earth — from its orbit of approximately 600 km above the earth’s surface — this would in theory correspond to 0.3 metres or 30 cm. Quite impressive! But Hubble would have to look down through the atmosphere, which would blur the images and make the actual resolution worse..
What is the deepest thing in the universe?
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall.
Can you see the rover on the moon with a telescope?
The Hubble telescope, with a paltry diameter of 2.4 meters, would be extremely ineffective in resolving the American flag. Now, let’s look at something that’s bigger than the flag – the lunar Rover. Its length is 3.1 meters, so it would take a telescope 75 meters in diameter to spot it.
What is a dead galaxy?
The “dead” moniker describes the fact that these galaxies no longer have the necessary cold hydrogen gas to make stars. Without the gas, there’s no clumping of matter that eventually leads to the formation of a star.
How far back in time can we see?
We can see light from 13.8 billion years ago, although it is not star light – there were no stars then. The furthest light we can see is the cosmic microwave background (CMB), which is the light left over from the Big Bang, forming at just 380,000 years after our cosmic birth.
What is the newest galaxy found?
HD1 is really far away. It breaks the record held by a galaxy called GN-z11 was discovered in 2017 at 13.4 billion light-years away and takes astronomers even closer to the “Big Bang.”
Are there stars without galaxies?
There may be a cosmic game of gravitational billiards going on, flinging stars into intergalactic space. Although stars cannot form in the voids between galaxies (since the density of matter is far too low), there are in fact large numbers of ‘intergalactic stars’.
Is time Travelling possible?
Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
Can we see 14 billion light-years away? We will never see the light from objects that are currently more than 15 billion light years away, because the universe is still expanding. We are losing 20,000 stars every second to an area that will forever remain beyond our future view.
Can you see the flag on the moon with a telescope?
Yes, the flag is still on the moon, but you can’t see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
What’s the biggest thing in space?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
Who owns the Moon?
The short answer is that no one owns the Moon. That’s because of a piece of international law. The Outer Space Treaty of 1967, put forward by the United Nations, says that space belongs to no one country.
How powerful does a telescope have to be to see the rings of Saturn?
The rings of Saturn should be visible in even the smallest telescope at 25x. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
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 is the hottest thing in the universe? The hottest thing in the Universe: Supernova
The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun’s core.
Can you see leftover equipment on the moon?
That means that there would be no way to discern the Lunar Excursion Module or any of the other equipment left on the moon. It is just too small to pick up, even with the world’s best telescope.
Is there a mirror on the Moon?
It’s amazing how much light our moon reflects. Having a few mirrors doesn’t hurt, though. They’re there because of the Lunar Laser Ranging experiment. In 1969 Buzz Aldrin placed a two-foot wide panel of mirrors on the Moon.
Is the US flag still on the moon?
An enduring question ever since the manned moon landings of the 1960s has been: Are the flags planted by the astronauts still standing? Now, lunar scientists say the verdict is in from the latest photos of the moon taken by NASA’s Lunar Reconnaissance Orbiter Camera (LROC): Most do, in fact, still stand.
What did NASA leave on the moon?
Besides the 2019 Chinese rover Yutu-2, the only artificial objects on the Moon that are still in use are the retroreflectors for the lunar laser ranging experiments left there by the Apollo 11, 14, and 15 astronauts, and by the Soviet Union’s Lunokhod 1 and Lunokhod 2 missions.
What has been left on the moon by humans?
Some of it is waste from the trip that the astronauts dumped when they got to their destination. Aside from trash—from food packaging to wet wipes—nearly 100 packets of human urine and excrement have been discarded. The Apollo astronauts also dumped tools and television equipment that they no longer needed.
Is there a US flag on the moon?
Two previous Chinese lunar missions had flags on the crafts’ coatings – so neither could be affixed to the moon. The US planted the first flag on the Moon during the manned Apollo 11 mission in 1969. Five further US flags were planted on the lunar surface during subsequent missions up until 1972.
Can you see the flag on the moon with Google Earth?
If you use the Google Moon App then you can see the equipment and the flag left behind after the first Moon Landing in 1969. There are even still footprints there where Astronauts Buzz Aldrin and Neil Armstrong walked on the surface of the moon.
Can humans travel to another galaxy? The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
