Over the past three decades, astronomers have discovered thousands of planets beyond our solar system. But while some of them might be the right size and mass to be some kind of Earth 2.0, we don't know if any of them is truly...

Have an idea you're yearning to turn into a business? Julissa Prado, founder and CEO of Rizos Curls, explains how she was inspired by the Latino and immigrant communities she grew up in -- and shares 3 principles that guide her in her...

The James Webb Space Telescope is the most ambitious space observatory ever launched, and nobody hyped it more than us. So is it putting in work? Oh, boy, yes. Yes it is.

In 2024, NASA plans to send the first humans to the Moon (well, around the Moon) in over 50 years ago. And in order to get the necessary oomph to hurl those astronauts over there, NASA will be using its most powerful rocket ever: the...

Mars has a ton of amazing features waiting to be explored, but we have to get there first. Thanks to our partners at the Boston Museum Of Science for helping us think about everything we need to plan a trip! Squeaks and Jessi would love...

Put on your spacesuits, because we’re off to explore Mars! We’ll learn all about how we could live there, and meet the robots that already do!<br/>

Right now, discarded parts from old spacecraft, bags of pee, and dead probes are just floating around in space, but it doesn’t have to be like that. Let's take a look at some of the ways we've figured out to reduce, reuse, and recycle in...

In honor of the spookiest time of year, let's take a look at the spookiest-named things in the cosmos.

2022 was a pretty exciting year for space science, but what news might we expect in the coming year?

During the 14th and 15th centuries, mercenaries known as condottieri dominated Italian warfare, profiting from— and encouraging— the region's intense political rivalries. As rulers competed for power and prestige, their disputes often...

In 1926, Robert Goddard launched Nell — the very first (successful) liquid fuel rocket. But Nell wasn't built like other modern rockets, including a notable lack of casing and an exhaust nozzle suspended above the propellant tanks.

Early this year, 3D printing showed off its space-age technology capabilities by printing most of a rocket that was launched into space.

Most of us are hoping that any nuclear threats are just empty threats, and getting at the facts about ICBMs can be difficult. But what would actually happen if someone launched a nuclear weapon?

If you ever get nervous about missile attacks, they're actually a lot harder to make than you might think. To hopefully put your mind more at ease, Hank is here to talk about the work that goes into designing and building ICBMs in this...

Flies are evasive buzzing machines that make it nearly impossible to swat. Luckily, science has some explanation to help you predict their next move. Hosted by: Stefan Chin

The pandemic forced the world to work together like never before and, with unprecedented speed, bore a new age of health and medical innovation. Physician-scientist Daniel Kraft explains how breakthroughs and advancements like...

The Kepler mission has determined that terrestrial planets are extremely common, and may orbit most stars in the Milky Way. But these planets are difficult to directly image because they're dense and small. Our Sun is about ten billion...

The James Webb Space Telescope has launched! But it was a very long road to get to this point, and we’ve been following the progress for a decade!

As we look towards longer missions to the Moon, the shear amount of resources needed to survive becomes a much bigger question. Without space semi-trucks to haul life-giving resources to astronauts, can we utilize the Moon’s barren...

Hank goes from space to sex and then to motherhood, covering the SpaceX launch, a mission to the moons of Jupiter, intersexual workplace rivalries, the evolution of male homosexuality, the fossil evidence of squishy baby skulls, toddler...

In this video Paul Andersen explains why astronauts are weightless. He also explains how Newton's Universal Law of Gravitation can be used to calculate the gravitational force between objects.

How does an astronaut prepare physically and mentally to launch into space? NASA astronaut Megan McArthur, who traveled to the International Space Station in April 2021 as part of the SpaceX Crew-2 mission, shares stellar life lessons...

TeD Fellow Negin Farsad weaves comedy and social commentary to cleverly undercut stereotypes of her culture. In this uproarious talk/stand-up hybrid, Farsad speaks on her documentary, The Muslims Are Coming!, narrates her fight with the...

So how can a game teach us about engineering? Pretty easily! When you're trying to solve a game, or a puzzle, or whatever, you will have a bunch of variables. The trick is knowing how to change one variable at a time to see what changes....
