10 Space Objects That Are Impossible To Wrap Your Mind Around

Posted on

Space is pretty cool, and a lot of it is pretty weird. Planets orbit around stars, which die and are reborn, and everything in the galaxy orbits supermassive black holes that slowly pull everything to their doom. But every now and again, space throws a curveball our way so bizarre that you’ll twist your mind into a pretzel trying to figure it out.

The Red Square Nebula

Things in space are fairly rounded, for the most part. Planets, stars, galaxies, and the shape of orbits are all at least somewhat circular. Then there’s the Red Square Nebula, a cloud of gas shaped like, well, a square. Understandably, this made astronomers do a bit of a double take, because things in space aren’t supposed to be square.

But it’s not really a square, either. If you look closely at the image, you can see that the cross shape really forms the sides of two cones with their tips touching, but there aren’t exactly tons of cones in the night sky, either. The hourglass-shaped nebula is so brightly lit because there’s a star at the very center—that is, where the tips are touching. It’s quite possible that this star could eventually detonate into a supernova, making the rings at the base of the cones glow with blinding intensity.

The Pillars Of Creation

As Douglas Adams once wrote, “Space is big. Really big. You just won’t believe how vastly hugely mind-bogglingly big it is.” We all know that the unit of measurement used for distances in space is the light year, but think about what that means. A light year is a distance so enormous that it takes light—that thing that moves faster than anything else in the universe—an entire year to traverse it.

That means that when we look at objects in space that are really far away, like the Pillars of Creation (a formation in the Eagle Nebula), we’re really looking back in time. How is that possible? Well, it takes light 7,000 years to reach Earth from the Eagle Nebula, and we see things by perceiving the light that bounces off of them. The light that we perceive as the Eagle Nebula is 7,000 years old by the time it reaches Earth.

The implications of this glimpse into the past can be pretty weird. For example, astronomers think that the Pillars of Creation formation was actually destroyed by a supernova about 6,000 years ago. Since it takes light so long to reach us, you can still see the pillars if you look up into the night sky, even though they no longer exist.
