Is there a 3D map of the galaxy?

Scientists have created the largest and most detailed 3D map of the universe using an instrument that has mapped out more galaxies than all other three-dimensional surveys combined.

Can I travel to a different 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.

Is there a cosmic web?

In the Universe, galaxies are distributed along extremely tenuous filaments of gas millions of light years long separated by voids, forming the cosmic web.

What is on the edge of the universe?

As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations.

Is Earth in the Orion Arm?

The Orion Arm is a minor spiral arm of the Milky Way galaxy some 69 across and approximately 69 in length. The Solar System and therefore the Earth lies within the Orion Arm.

Where is Earth in Milky Way?

Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.

Will humans ever leave the Solar System?

Climate change is altering our planet, and some have wondered if we may have to leave Earth to another distant planet. We will never escape climate change, and unfortunately, we will never leave the Solar System, and Earth may be our home forever.

Does the multiverse exist?

Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists.
