Whether or not you think humans should be announcing our presence to the cosmos, we're doing it, anyway. Both intentionally, and not. And if aliens really do exist, there are several ways they could find us. Here are six of them.

The Pioneer 10 and 11 probes were launched to explore outer space, but in the 80s scientists discovered they were veering off-course, and we had no idea why!

Every amazing mission you know about today started off as just an idea, and some of 2019’s early phase NIAC concepts could mean big things for our future.

Humans have never visited another planet, but we can send special spacecraft called probes to visit them for us! One of those probes, called Voyager 1, has gone deeper into space than any other, and it's sent us some amazing pictures...

Let's take a moment to remember the selfless sacrifices made by some amazing robotic explorers.

Most of the time, it’s not great when an expensive spacecraft slams into an extraterrestrial body. But now and then mission control intentionally crashes a spacecraft for science!

A lot of our knowledge of the inner solar system was gained fairly recently, and the Mariner program led the way!

Akatsuki missed Venus once, but with a little ingenuity and its secondary engines, it's heading back on December 7th!

For more than 40 years, the Voyager probes have traveled through space sending back all kinds of fascinating data. But these probes were never meant to send us data forever - so how much longer will these amazing probes last?

Earlier this year, scientists pitched a mission to bring 'the cloud' to Mars. While this proposal may seem expensive and risky, it's a legitimate idea that could fundamentally change how we plan space missions!

NASA is launching a mission to send a probe into the sun, and it's the first to be named after a living scientist: Eugene Parker and the Parker Solar Probe! Astronomers have found another hot topic, and it's the hottest planet we've ever...

Mars One. The Mars Rover. Bruno Mars. Mars Bars. It's pretty clear we're OBSESSED with the idea of Mars, especially in regard to it being a potential colony for earthlings. But is that really the best option? Is there a better place for...

Hank tells us about the planned demise of two lunar satellites that have been collecting data for NASA, and have now reached the end of their mission.

To figure out an organism's genome and DNA sequence, field biologists need big, expensive equipment in the labs. But, new high-tech devices help scientists to examine samples on the sites!

Hank updates us on two new missions that will help us learn more about some of the fascinating things in our space neighborhood.

Big, fiery rocket launches are just too powerful for something like a toaster-sized CubeSat once it’s in space. Electrospray propulsion is a promising new way to move these little satellites.

Paul Andersen explains how mathematics and computational thinking can be used by scientists to represent variables and by engineers to improve design. He starts by explaining how mathematics is at the root of all sciences. He then...

NASA's working on a mission to send a probe and a lander to Europa, but there are many challenges to overcome to make it happen.

Welcome back to the FLUCTUS channel to witness the presence of the U.S. military in the world’s coldest region, Antarctica. Fluctus is a website and YouTube channel dedicated to sea geeks. Whenever you are curious or an incorrigible...

This video will teach us about the six port states: open, closed, filtered, unfiltered, closed/filtered, and open/filtered.

Insane (for the time) Voyager engineering.

A look at permanently shadowed regions on the Moon where NASA and KARI hopes to find water ice.

The journey of Voyager I and II beyond the orbit of Neptune.

We need to better understand the Sun. Here's why NASA (Parker Solar Probe) and ESA (Solar Orbiter) have both sent probes to the Sun in the last few years.
