How far away from Earth could you see the planet with your eyes alone if you were in space? Using merely brightness as a guide, the answer is around 9 billion miles (14 billion kilometers) distant, which is roughly the distance between Neptune and Pluto. In actuality, however, observing it from that distance would be difficult due to the glare of the sun, which would obscure the view of the Earth.

How far in space Can you see the whole earth?
Theodore von Kármán, a Hungarian scientist who lived in the 1900s, calculated that the barrier was around 50 miles high, or approximately 80 kilometers above sea level. Today, however, the Kármán line is fixed at what the National Oceanic and Atmospheric Administration (NOAA) refers to as “an imaginary limit” that is 62 miles or nearly a hundred kilometers above sea level.
How far in space can we see?
The furthest distant object that Hubble has observed is around 10-15 billion light-years away. The Hubble Deep Field is the name given to the area that has been seen from the deepest distance.
How far back in time can we see?
We discussed before that the greatest distance we may observe in a non-expanding universe is twice the age of the Universe in light years: 27.6 billion light years.
How long is 1 hour in space?
Answer: The product of that number multiplied by one hour is 0.0026 seconds. In this case, a person in that deep space location would have a clock that would operate for one hour, while that individual computed that our clock ran for 59 minutes and 59.9974 seconds.
Where on Earth can you see space?
Taking in everything from the world’s largest rivers and mountains to ancient pyramids, we take a look at some of the most stunning sites on the planet that can be viewed only by spacecraft.
- The Great Pyramids of Giza in Egypt
- The Grand Canyon in the United States
- The Himalayas
- The Great Barrier Reef in Australia
- The Amazon River
- Palm Island in Dubai
- The Ganges River Delta
- The Great Wall of China
Are there any real pictures of the Earth?
Nasa has revealed the first image of the Earth it has taken in 43 years, which was shot from the International Space Station. After more than 40 years, a camera on board the Deep Space Climate Observatory (DSCOVR) has taken a picture of the whole planet, which is the first such image since 1972.
Does space ever end?
No, they do not think that there is an end to the universe. However, we can only view a limited amount of what is out there at any given time. The universe is 13.8 billion years old, which means light from a galaxy more than 13.8 billion light-years away hasn’t had enough time to reach us yet, and as a result, we have no way of knowing whether or not a galaxy of that distance exists.
What is in the end of universe?
Astronomers previously speculated that the cosmos could collapsing in a Great Crunch. Now, almost everyone agrees that it will end in a Big Freeze. The cosmos will drift apart for billions of years after the Earth is destroyed, long after the Earth has been destroyed. This will continue until galaxy and star formation is no longer possible.
What is the farthest thing we have seen in space?
The galaxy GN-z11 seems to be the furthest detectable galaxy from us, according to prior research, with a distance of 13.4 billion light-years or 134 nonillion kilometers (that’s 134 followed by 30 zeros) from us, according to Kashikawa’s remark.
Is time Travelling possible?
To summarize: Yes, time travel is a genuine possibility. However, it is not quite the same as you may have seen in the movies. While under specific situations, it is possible to perceive time advancing at a rate other than one second every second, or even faster.
Are we looking at the sun in the past?
Yes, you are quite correct. Not only do we see the Sun 8 minutes in the past, but we also see the history of everything else in space, including the Earth. We can even view the Moon, who is our closest partner, 1 second in the past.
How long would it take to travel 4 light years?
Last year, researchers speculated that our nearest neighbor, Proxima Centauri, may contain a number of potentially habitable exoplanets that may meet the criteria for life on our planet. When measured in light years, the distance between Earth and Proxima Centauri is 4.2 light-years, which would take around 6,300 years to traverse with current technology.
How much do astronauts get paid?
Civilian astronauts are paid in pay grades ranging from GS-11 to GS-14, which are determined by their academic achievements and work experience. Currently, a GS-11 astronaut earns a starting pay of $64,724 per year, while a GS-14 astronaut can earn a salary of up to $141,715 per year [source: NASA].
Do we age slower in space?
We all have a distinct way of measuring our experiences in terms of space and time. Due to the fact that space-time is not flat, but instead is curved, and it can be twisted by matter and energy, this is true. And for astronauts aboard the International Space Station, this implies that they will age only a smidgeon slower than folks on the ground. Because of the consequences of time dilation, this is the case.
Is an hour in space 7 years on Earth?
The time-dilation effect of Einstein’s relativity has absolutely nothing to do with spatial dimensions of any kind. The quicker you move, the slower time appears to be moving for you. So if you were on a planet that was traveling extraordinarily quickly across space, such as the one shown in the movie Interstellar, you might lose seven years on Earth for every hour you were on the planet.
