At the age of 17, Corey Pegues joined one of Queens, New York's most formidable gangs, the Supreme Team. He soon realized the threat that this lifestyle posed to himself and his family and sp he quit the crew and join the New York City...

We don’t yet know the long-term health consequences of e-cigarettes, and gaining that knowledge could take decades. However, a recently published study in mice offers new data for consideration.

Miss Palomine explains that a scientist makes predictions based on observations, made either by himself or by other scientists. She defines both words and gives examples.

Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners, but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local...

Today, thanks to better early detection, there are 63% fewer deaths from heart disease than there were just a few decades ago. Thomas Insel, the director of the National Institute of Mental Health, wonders: Could we do the same for...

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular....

With so many galaxies in the universe, some are bound to astound us. Here are three of the most extreme galaxies scientists have discovered so far.

We've been trying to count the galaxies in the universe since the mid '90s, but our estimates change as our tools improve. So what does our current estimate really mean?

Quantum mechanics is our best theory of the fundamental nature of reality, but it's usually only distinguishable from familiar classical mechanics on the smallest scales. But it’s also possible that our entire galaxy is filled with a...

The Milky Way is often described as measuring 100,000 light years across and containing the mass of a trillion Suns. But our home galaxy is actually far bigger, and might be much less massive. Astronomers aren't sure what the exact stats...

The universe is a big place full of galaxies that we've only begun to study. SciShow Space presents 3 of the strangest ones we've found so far.

Scientists have spotted a galaxy from the early origins of the universe, and found evidence to support the existence of a 9th planet in our solar system.

A voyage on a river can take you to the heart of an unfamiliar place, and also free you from some of the stress of travel. ➡ Subscribehttp://bit.ly/NatGeoSubscribe' target='_blank' rel='nofollow'>Subscribe About National Geographic:...

Paul Andersen describes our place on the Earth in the Solar System within the Milky Way Galaxy in the Universe. The make-up and origins of the Universe are included along with stellar evolution. A teaching progression K-12 is also...

For most of human history, we didn't know that galaxies were a thing. So over the past century, astronomers have been working to understand how galaxies come to be and how they evolve over time. And for a full decade, there was one...

Submillimeter galaxies are ancient, dense, massive galaxies with up to 10 times the number of stars in the Milky Way, and for a long time, scientists couldn’t even figure out how they existed in the first place.

Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with a Big Bang, when...

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip. -- We know about our universe’s past: the Big Bang theory predicts that all...

In the aftermath of a 8 – 20 solar mass star’s demise we find a weird little object known as a neutron star. Neutrons stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars,...

Sometimes galaxies eat each other! It's actually pretty common. And it turns out that our own galaxy, the Milky Way, is pretty hungry.

Astronomers have found a couple galaxies that were much larger than expected, and the Opportunity rover might be in for some harsh Martian weather!
