How many light years can we travel?
Even if the fabric of space didn’t change over time, there are plenty of objects we can see today that could be farther away than 13.8 billion light-years. The only catch is that their light could travel for 13.8 billion light-years at most; how the objects move after emitting that light is irrelevant.
How long would it take to travel 100 light years?
roughly 1,736,809 years
What is 100 light years away from Earth?
The planet, currently known as TOI 700 d, is about 100 light years away. It is orbiting a star that is about 40 percent of our sun’s mass and size, according to CNN. TOI 700 d is one of three planets orbiting its star. Researchers say it is just the right distance from the star to support liquid water.
How fast can a human travel in space?
Surprisingly, the fastest manned mission record still belongs to Apollo 10, which took place back in May 1969. During its return from the Moon, the crew’s vehicle reached a speed of 24,791 mph (39,897 km/h).
Can we see distant galaxies in the Milky Way?
Answer: Yes, you can see a few other galaxies without using a telescope! The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.
How far to the edge of the Milky Way?
Distance Information The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.
Is the earth at the edge of the Milky Way?
The earth is on the Milky Way Galaxy.
How old is the oldest star in the universe?
about 13.2 billion years
How old is GRB 090423?
On April 23, 2009 the Swift satellite detected a gamma ray burst and as we reported back in April, scientists soon realized that it was more than 13 billion light-years from Earth. GRB 090423 occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.
What Does the Milky Way really look like?
The Milky Way is a spiral galaxy. The spiral arms contain stars, cold molecular gas, glowing star- forming regions and dark dust. The galactic bulge contains mainly older stars, and appears redder than the spiral arms. Since the central bulge is elongated, the Milky Way is classified as a barred spiral galaxy.
