How old is light from the Moon?
It's also about 380,000km away, so it takes 1.3 seconds for light to travel from the Moon to us. We see the Moon not as it is, but as it was 1.3 seconds ago. The Moon doesn't change much from instant to instant, but this 1.3-second delay is perceptible when mission control talks to astronauts on the Moon.
How much time does light take to travel from Sun to Earth?
Light travels with a speed of 3 × 108 m/s in vacuum. Sunlight takes 8.3 minutes to reach the earth.
How many Earth years is a Lightyear?
Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year.
How far back can you see in space?
Essentially, we are seeing that object as it appeared 13 billion years ago. With every year that passes, our newest technology enables us to see further and further back. The image used for this stop on our journey is the Hubble Ultra Deep Field (UDF).
How long does it take to get to Mars?
The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).
How old is the light we see from the Sun?
The sunlight we see is 170 000 years and 8.5 minutes old. It is ancient!
What is 1 light year away?
about 5.9 trillion miles A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.9 trillion miles (9.5 trillion km).
How many miles is the Universe?
It's about 238,855 miles on average, and I say on average, because the distance does change.
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.
Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
What planet takes 7 years to get to?
Saturn FAQ – Spacecraft

|---|---|---|
| Messenger | Mercury | 6.5 years |
| Cassini | Saturn | 7 years |
| Voyager 1 & 2 | Jupiter; Saturn; Uranus; Neptune | 13,23 months; 3,4 years; 8.5 years; 12 years |

Do we age faster in space?
Training on the simulated martian terrain of Mars-500. Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
Can we see back in time?
As it takes a really long time for light to travel we can essentially look way back in time from when stars and planets were formed after the Big Bang. The light that reaches the James Webb space telescope may have traveled millions of miles from a star that no longer exists.
How far back in time can we see?
The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years.
How long would it take to get to Mars?
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
What’s bigger than the universe?
No, the universe contains all solar systems, and galaxies.
What is the deadliest thing in the universe?
Death by black hole Black holes are expected to form when a massive star dies. After the star's nuclear fuel is exhausted, its core collapses to the densest state of matter imaginable, a hundred times denser than an atomic nucleus.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
What is bigger than the universe?
No, the universe contains all solar systems, and galaxies.
How cold is space?
In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have. So in a truly empty region space, there would be no particles and radiation, meaning there's also no temperature.
Do you age in space?
In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.
How long is trip to Mars?
The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).
How much do astronauts get paid?
The pay grades for civilian astronaut candidates are set by federal government pay scales and vary based on academic achievements and experience. According to NASA , civilian astronaut salaries range from $104,898 to $161,141 per year. Here are a few of the benefits offered to civilian astronauts: Health care.
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.
How long will Universe last?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.
How long will it take to go to Pluto?
With a maximum velocity of 590 miles per hour, the trip to Pluto will only take about 680 years. Which really puts things into perspective when considering just how wild it is that we have a spacecraft about to reach Destination Pluto.
What are 3 things found in the universe?
The universe is filled with billions of galaxies and trillions of stars, along with nearly uncountable numbers of planets, moons, asteroids, comets and clouds of dust and gas – all swirling in the vastness of space.
Is there color in space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

Who created the God?
We ask, "If all things have a creator, then who created God?" Actually, only created things have a creator, so it's improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.
