How Long Will It Take To Fall Through The Earth?

You might not want to check this out for yourself, but do you know how long it would take for a person to fall through the Earth? Around 42 minutes.


What Would Happen To Our Solar System If Jupiter Didn't Exist?

Video: Our solar system is weird. Not only because we’re unique little snowflakes on a blue marble called Earth, but because other stars usually have their giant arse planets (that is, their Jupiter) orbiting them at a much closer distance. This is really common in other systems! Our Jupiter, however, doesn’t work like that. Why?


Saturn's Moon Titan Is Looking Even More Earth-Like

The Cassini mission is sending us better and better data and images of just what’s happening on the surface of Saturn’s moon Titan. And it’s beginning to look awfully familiar…


How Many People Can The Earth Actually Hold?

Video: There’s over seven billion people on this planet of ours and some estimates peg the population to reach 10 billion by the end of the century. Given that there’s only a certain amount of land on Earth, is there a maximum amount of humans that our blue marble can support? Sort of! And that limit is tied to our diet and the land we need to dedicate to livestock (the size of Africa!) and crops (the size of South America!).


NASA's 4K Earth Porn Montage Is Beautifully Peaceful

Video: Queue up that 2001 soundtrack, baby! Following up on the incredible Aurora Borealis and Australis footage that NASA posted a few days ago, we can now marvel at crystal clear 4K footage of our home sweet home, covered in white clouds and blue sky. Now that NASA and the astronauts on the ISS are shooting and sharing videos in glorious 4K, you finally have a perfectly justifiable reason to upgrade your TV.


A Nightmarish Timeline Of Earth's Fate After A Massive Solar Flare

At first, things could actually be rather beautiful: worldwide auroras! A brighter sun! But then things would rapidly get ugly, with the breakdown of communications, rolling power outages, and a burning away of the ozone.


The Vernal Equinox Isn't What You Think It Is

Video: Yesterday was the vernal equinox, or the autumnal equinox for those of us in the southern hemisphere. You might think that it’s simply the mid-point between each solstice, but that’s not exactly correct. Joe Hanson, host of It’s OK to be Smart, explains.


When You Think Of Beautiful Things, Don't Forget Earth

Image cache: Scott Kelly posted up a stunning picture of Earth earlier this week, with a fitting caption: “When you think of beautiful things. Don’t forget Earth.”


The Earth And Moon As We Know Them Were Created In A Violent Collision With Another Planet

4.5 billion years ago, when Earth was 100 million years old, Theia — a planetary embryo around the same size as Earth — crashed into our planet in a “violent, head-on collision” creating one single planet — and the moon.


Savour The Snow From Far, Far Away

Image Cache: Australia is lucky. For those in the US, the beauty of winter can be difficult to appreciate when constantly shovelling walkways, scraping ice off cars and tromping through freezing slush. Meanwhile Australians can simply admire that beauty from afar – and now, above as well, far away from the chilly realities of the season.
