Where are the biggest galaxies?

The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.

What is the rarest type of galaxy?

Only 1-in-10,000 galaxies fall into the rarest category of all: ring galaxies. With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag’s object.

Can we go 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.

Can you touch a star in space?

No. While none exist to date it would be possible for a dead star to have cooled to a safe temperature. However, such objects are inherently supported by degeneracy pressure–they’re very dense.

Is it possible to leave this universe?

We can’t travel out of the universe, any more than we can travel through time. Both are happening in a “direction” that physics doesn’t allow us to move. For a balloon, all the intrinsic curvature can be measured by an ant on its surface, and that’s all physics needs.

Have we ever left the Milky Way?

On November 5, 2018, Voyager 2 officially left the solar system as it crossed the heliopause, the boundary that marks the end of the heliosphere and the beginning of interstellar space.

Will Voyager 1 ever stop?

Engineers expect each spacecraft to continue operating at least one science instrument until around 2025. Even if science data won’t likely be collected after 2025, engineering data could continue to be returned for several more years.

What is beyond our universe?

To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then there can’t be anything outside the universe.

Can you land on a star?

The calculations show that, even using the most theoretical of technologies, reaching the nearest star in a human lifetime is nearly impossible.

Is there any human lost in space?

On 31st October 2014, another astronaut was lost in space. It was Michael Elsbury, the pilot of the suborbital spacecraft SpaceShipTwo of Virgin Galactic. During the 55th test flight of the ship, serious anomalies were discovered, which led to the spacecraft crash.

Which planet can human live on?

Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
