Galaxy trivia - did you know?

A place for all the 100% useful and meaningful trivia about the galaxy we live in! Wink

Please share a fun fact about space, space travel or even movie lore facts below. 

All just for fun and to learn a little something new! Dizzy

  • "Voyager 1 was the first spacecraft to cross the heliosphere, the boundary where the influences outside our solar system are stronger than those from our Sun."
    And it has a record of Chuck Berry playing "Johnny B. Goode"

  • The closest star to Earth is Proxima Centauri. It's about 4.2 light-years away, which means it would take about 4.2 years for light to travel from Proxima Centauri to Earth.

    The movie “Gravity” was filmed entirely in a soundstage. The special effects team created the illusion of space by using a combination of CGI and practical effects. The film was produced entirely in the United Kingdom, where British visual effects company Framestore spent more than three years creating most of the film’s visual effects, which involve over 80 of its 91 minutes.

    The fastest speed ever recorded by a spacecraft is the Parker Solar Probe, which is currently studying the Sun. On its 10th close solar flyby on Nov. 21, 2021, the sun's powerful gravity accelerated the probe to a top speed of 101 miles (163 kilometers) per second, which translates to an astonishing 364,621 mph (586,000 kph).

  • NASA has revolutionized our understanding of the universe and pushed human exploration to new heights. One fun fact about space is that there are four known forces in nature: gravity, electromagnetism, weak nuclear force, and strong nuclear force. However, when NASA launched their twin Voyager probes into interstellar space in 1977, they discovered a fifth force called "hybrid impressions," originating from structures deep in the cosmos. This force has allowed us to see beyond typical gravitational lensing effects and uncover previously hidden features of our universe. Scientists have used hybrid impressions to observe objects too faint or distant for traditional telescopes and discover more about dark matter and its influence on galaxies throughout our universe. With further study, hybrid impressions could continue to shed light on the mystery that is our vast universe.

  • We measure distances by attempting to use the third leg of a triangle from one side of the earth to the other.  However, when looking at stars, that distance is so infinitesimally small compared to the star we are measuring, that it makes you wonder at the accuracy.

  • The sped of light is 186,282 miles per second. I have had that number memorized since I was a kid, and there is a rarely a situation where that comes in handy.

  • nothing to share but to learn from all these facts being shared!

  • On Venus, the average temperature is +462°C. I think I'm already there!

  • Galaxies can collide with each other.

  • We have a massive black hole as a part of our galaxy. It's called Sagittarius A. If we talk about its size, only a few million earths can fit inside it Slight smile

  • I kind of believe the world could be flat and that God created us as center of universe.
