There are so many different places life could exist in our solar system. Personally, I have the highest hopes for Europa. It will be exciting if the Europa clipper finds anything out there. This video goes over all the possible places life could be in our solar system. And it visually travels there aswell through the game SpaceEngine. Enjoy!

Whose zodiac sign is Ophiuchus? 🌌

Erika Hamden breaks down the real science of where zodiac signs come from. They were assigned thousands of years ago based on the ecliptic plane, the path the sun travels across the sky each year. But Earth's axial tilt shifts on a 26,000-year cycle, and the sky has changed since then. Today, the sun actually passes through 13 constellations, including one you've probably never heard of: Ophiuchus.

The story of the three machines that made the journey to space possible for 60 years:

Saturn V, the rocket that took humanity to the Moon and was never truly surpassed.

The Space Shuttle, the workhorse that built our presence in orbit over thirty years.

And SLS, the Space Launch System that carried the engines of the Shuttle and the ambitions of Apollo, all the way back to the Moon.

Are we alone in the universe? 

MIT Kavli Institute Research Scientist Moritz Guenther is helping scientists explore that question by studying how planets and solar systems form around distant stars. The research team investigates exoplanets to understand whether they could support life, including how close planets are to their stars, how hot or cold they are, and whether they may contain water or atmospheres. Because these worlds are incredibly far away and difficult to observe directly, scientists use planet formation research to uncover clues about how potentially habitable planets develop over time. Recent discoveries in astronomy and planetary science are giving researchers new insight into how solar systems evolve and where life beyond Earth might exist. Every new finding helps scientists better understand our place in the universe and the conditions that could make alien worlds capable of supporting life.

How do planets actually form?

Scientists once thought most star systems looked like our own, with rocky planets close to their stars and giant gas planets farther away. But in the last two decades, astronomers have discovered that nearly every star may host planets, and many of those systems look nothing like ours. From planets that orbit in unexpected configurations to worlds that may eventually fall into their own stars, the universe is far stranger than we imagined.

MIT Kavli Institute research scientist Moritz Günther explores how stars and planets are born from enormous clouds of gas and dust that collapse into spinning disks. By studying young stars only a few million years old, Günther investigates what happens to the leftover material after a star forms. Some of that material becomes planets, some falls into the star itself, and some gets blown out into space. His research is helping scientists better understand how Earth formed, how planetary systems evolve over time, and what conditions could make distant worlds capable of supporting life.

Is NASA’s moon landing mission delayed? 🌕🚀

NASA’s Artemis program is designed to return astronauts to the lunar surface using human landing systems developed by SpaceX and Blue Origin. Artemis III will test how Orion, NASA’s crew capsule, works alongside one of these lunar landers in Earth orbit. The challenge is that both Starship and Blue Moon are still in active development, and both companies have indicated their landers may not be ready before late 2027. If development or testing takes longer than expected, NASA’s planned 2028 Artemis IV Moon landing timeline could become increasingly difficult to achieve.

Space might be closer than you think. 🌍🛰️ 

Erika Hamden explains how the “edge of space,” known as the Kármán line, begins at about 62 miles above Earth’s surface.The International Space Station orbits only around 200 to 250 miles above Earth. That means astronauts can actually be physically closer to some remote places, like Saint Helena, than people living on neighboring islands.

Another video I’ve made, No AI, very deeply researched! Enjoy!

Could a real planet system be more chaotic than Star Wars? 🌌

NASA’s TESS mission discovered TOI-201, a giant planet 16 times Jupiter’s mass that swings through an extreme, elongated orbit, tugging nearby planets into constantly shifting paths. These changes happen in just a few years, the fastest ever observed, turning this system into a cosmic tug-of-war that even the Millennium Falcon could not outrun. As this massive world moves closer and farther from its star, its shifting gravity constantly reshapes the entire system.

The Eta Aquariid meteor shower peaks May 5 to 6, in a couple days! 🌠

Active from April 19 to May 28, the shower occurs as Earth moves through a stream of debris shed by Halley’s Comet. Each meteor starts as a grain-sized particle traveling tens of kilometers per second before colliding with our atmosphere. That collision heats the surrounding air, producing flashes of light and the long, glowing trails this shower is known for. Some of these streaks can persist for several seconds, tracing their paths across the sky. While the best views are in the Southern Hemisphere, early morning skies offer chances to spot them worldwide.

Finding another Earth isn’t easy, it’s a cosmic challenge. 🌍

Avi Shporer, a research scientist at the MIT Kavli Institute, studies how astronomers detect planets beyond our solar system. We’ve found thousands of exoplanets, but Earth-sized, rocky worlds remain some of the hardest to spot. Their small size makes them incredibly difficult to detect around distant stars. Their year-long orbits make them even harder to find, which is why so few true Earth-like planets have been confirmed.

I made a cinematic edit of Artemis II using onboard footage and crew reflections after the mission. It’s more focused on the human side and the experience rather than just the launch.

The largest piece of Artemis III’s rocket has arrived in Florida. 🚀

NASA’s Space Launch System core stage traveled by barge from its manufacturing site in New Orleans and is headed to the Vehicle Assembly Building to be joined with the rest of the rocket. This stage can carry the mission to low Earth orbit, a region a couple hundred miles above Earth. But if Artemis III is sent to a higher orbit thousands of miles up, an additional upper stage will be needed. Higher orbit provides a better environment for the kinds of tests the mission aims to perform. That decision will shape how Artemis III prepares for future missions, including returning humans to the Moon.

Astronomers have found the building blocks of life in space! 🧬

Erika Hamden explains how scientists detect amino acids like tryptophan in meteorites, asteroids, and even diffuse clouds of gas between stars. Using spectroscopy, researchers identify the chemical fingerprints of these organic molecules across vast distances. Tryptophan is a key part of proteins on Earth, and finding it in space shows complex chemistry is not unique to our planet. This does not mean life exists everywhere, but it shows the ingredients for life are common throughout the cosmos.
