You can thank dark matter! As the universe expanded, dark matter became a web that stretched across space. It pulled in normal matter to create galaxies.

Scientists have been searching for dark matter particles for years, yet we still have no idea what they look like. One theory suggests we can’t find it because there are many different dark matter particles.

We can’t see it, but the universe appears to be full of this invisible mass.

Space smells like gunpowder and steak.

Blueberries found on Mars prove that there has to be flowing water, iron, and wind that can strip away fossil sand dunes.

This impact would make the one that killed the dinosaurs look like a pebble. It may have been the size of Pluto.

Scientists are split on where we should search for life. Sand dunes? Lava tubes?

Who doesn’t want to go to the red planet?

There is a giant area that is colder and emptier than it should be. How did it get there? We have to look back to the Big Bang.

It’s beautiful, but catastrophic. Even the smallest bits of matter travel at 400,000 miles per hour after the collision.

There’s a level of danger out in space that’s beyond even our own imaginations. We asked our How the Universe Works experts to describe the most mind boggling way the universe could kill us.

A neutron star is one of the most dangerous objects in the universe. Neutron stars are the densest things besides black holes. A stone sized piece of this star would weigh 100 million metric tons.

Take it from us, you don't want to smell like a comet.

Think of it like a cosmic ray gun. The energy released from a gamma ray burst is equivalent to a hundred trillion nuclear weapons going off every second for a hundred billion years. They can reduce planets to vapor.

Stars go out with a bang. It’s an incredible light show.

We’re not joking. It’s actually a thing. These stars rise from the dead and take revenge on the vampire stars that sucked the life out of them.

Exoplanets are smaller and dimmer than stars. It makes them incredibly difficult to spot.

Some alien worlds orbiting red dwarf stars might resemble giant eyeballs. They could be some of the most beautiful places to live in the universe.

The Earth could be a second generation planet.

It’s beautiful, but don’t get too close. The planet’s density exerts a gravitational pull over 15 times stronger than on Earth.

The area where dark meets light on an exoplanet is called the terminator line.

Meet the artist who has created a machine that creates portraits using his own blood as ink. The result is some amazing art but even more interesting science.

As if making origami cranes wasn’t impressive enough, see how one man makes them dance together. Tiny magnets control their synchronized movement.

The solar system is more geologically active than you might think.

Jupiter’s red eye has been swirling for at least 350 years.

Einstein's theory of general relativity was not always considered correct. It wasn't until Hubble made a grand discovery that the equation was fixed.... or was it? Some scientists believe the equation should actually go back to it's original form due to dark energy.

Dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe.

Luckily the Cassini spacecraft was there to witness one of these storms.

Before heading into the solar system and beyond, get the latest weather conditions.

Volcanic activity on Io, one of Jupiter’s moons, could be the key to the planet’s extraordinary auroras. Here’s how scientists at Syracuse University in New York have recreated volcanic activity on Io.
