Exoplanets: Unfamiliar, Wondrous Worlds [Video]

There’s a huge amount of variety among exoplanets – planets outside our solar system. There are water worlds, lava planets, egg-shaped worlds, planets with multiple suns, and even planets with no sun at all! What can we learn from all this weird, wondrous variety?

Weird Exoplanets

There’s a huge amount of selection amongst exoplanets – planets outside our solar system. There are water worlds, lava planets, egg-shaped worlds, planets with more than one suns, and even planets with out a solar at all! What's going to we be taught from all this uncommon, wondrous selection? What does it repeat us about every the exoplanets themselves and our own home planet?

Video transcript:

[Narrator] Earth is awesome.

What would possibly perhaps perhaps be indispensable more awesome, if we chanced on one more earth, or a bunch of earths.

That’s one among the issues we’re in search of at

" knowledge-gt-translate-attributes="[{"attribute":"data-cmtooltip", "format":"html"}]">NASA as we survey exoplanets, planets outside our solar system.

However presumably in search of a planet similar to our own, the place cases would possibly perhaps perhaps moreover need resulted in an fully odd origin of existence, in the end telling us that we’re no longer alone in the universe, presumably that’s no longer your thing.

That’s cool.

Perchance you’re more attracted to precisely how uncommon exoplanets would possibly perhaps perhaps moreover be.

We judge there are total worlds lined by deep oceans, water worlds.

Now not uncommon ample for you?

K. How about planets lined fully in oceans of lava?

There are egg-shaped planets, worlds that orbit so end to their stars that they’re pulled by gravity staunch into a lopsided shape.

And there are planets the place cases would possibly perhaps perhaps moreover be appropriate appropriate for it to rain issues enjoy glass, and even rubies and sapphires.

There are planets that orbit pairs and even groups of stars. Imagine having three or four suns in the sky!

On the reverse close of the spectrum, there are the loners, rogue planets wandering out in place with out a star to name their own.

There are even planets that orbit needless stars, stars that exploded manner serve and left in the serve of a without note spinning core called a pulsar. All these pulsar planets will doubtless be amongst the oldest in our galaxy, pushing 13 billion years.

Such planets would enjoy witnessed lots of the history of the universe. Sadly, nearly all of it without tacos.

Now, we judge that we haven’t chanced on one yet, that there doubtlessly are exoplanets barely similar to earth available.

However in the period in-between, there are completely hundreds uncommon, wondrous worlds in our galaxy.
