As of January 25, 2020, Voyager spaceprobe, the farthest human-made object from Earth, is 200 AU away. … Light in a vacuum travels around 300,000 kilometres (186,000 mi) per second, so 1 light-year is about 9.461×1012 kilometers (5.879 trillion miles) or 63,241 AU.

What’s bigger than a galaxy?

Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy. … Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!

Will we ever travel to other galaxies?

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.

What is the biggest celestial object?

The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!

Are there two Earths?

A research team discovered two Earth-like planets in our cosmic backyard, and they’re located in the perfect zone for water to form on their presumably rocky surfaces. The planets orbit a sun known as “Teegarden’s star,” which is only 12.5 light-years from Earth.

What is the smallest thing in the universe?

An atom is the smallest unit of any element in the periodic table. … Experiments found that each atom has a tiny, dense nucleus, surrounded by a cloud of even tinier electrons. The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe.

Is Earth in a void?

Earth and its parent galaxy are living in a cosmic desert — a region of space largely devoid of other galaxies, stars and planets, according to a new study. … That previous study showed that Earth’s galaxy, the Milky Way, is part of a so-called cosmic void.
