The Moon is tidally locked to the Earth, which means that it always shows one face to our planet. In fact, this is the case for most the large moons in the Solar System. What's the process going on to make this happen?
Jupiter’s iconic Great Red Spot is a huge cyclonic storm big enough to swallow the Earth. But it’s been getting smaller over time, while other storms have been growing. What does the future hold for this Jupiterricane?
Have you ever wondered how you can see your house from space... for free? What are the satellites taking those pictures of Earth anyway?
Did you know that the International Space Station (ISS) is one of the brightest objects in the night sky? You just need to know where, and when to look. So how to see ISS?
Imagine the Big Bang, and you're imagining an explosion. There must be come place we could travel in the Universe and see the wreckage left over from the Big Bang. So, where is it?
Have you ever wondered how old the Earth is? How early scientists tried to get an answer for this puzzling problem, and how modern science has finally given us an answer?
Today #365DaysOfAstro explains how many stars there are. How many can you see with your eyes, with binoculars or a small telescope? How many stars in the Milky Way? How many in the entire Universe?
We hear that black holes absorb all the light that falls into them. And yet, we hear of black holes shining so brightly we can see them halfway across the Universe. What's going on? Which is it?
Since telescopes let us look back in time, shouldn't we be able to see all the way back to the very beginning of time itself? To the moment of the Big Bang?
Have you ever wondered how old the Earth is? How early scientists tried to get an answer for this puzzling problem? And how modern science has finally given us an answer by looking at meteorites? More at #365DaysOfAstro
Today podcast will tell you what is the biggest star in the Universe, as well as the most massive star, and explores the limits that stars can reach. More at #365DaysOfAstro with @fcain
Look at those astronauts, flying through space without a care in the world. But how can they be floating when there's gravity pulling at them in every direction?
In science fiction, wormholes are a method often used to travel great distances across space. Are these magic bridges really possible?
Today on #365DaysOfAstro, lets explore on how fast you're spinning in space right now, and how you'd actually gain a little weight if the Earth stopped spinning. How Fast Does the Earth Rotate?
What temperature do astronauts experience? What about Pluto, or the depths of space. What's the coldest possible temperature space can get?
It seems like the good times will go on forever, so feel free to keep on wasting energy. But entropy is patient, and eventually, it'll make sure there's no usable energy left in the Universe.
We know trips in space will take a long time. Can we go to sleep for the journey and then wake up when we arrive?
Today's show is about the idea of space force to deal with the future warfighting in space. It turns out, this already exists, space is already well militarized.
Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse. So how to get enough power in space?
We try to avoid thinking about it, but spacecraft are machines that break down and eventually fail. Some can last for years, others decades, but in the end they’ll be gone forever.
Every time we send a spacecraft to another world, our Earth-based lifeforms are going with us. No matter how well we try to keep them clean, a few stowaways will always come along for the ride.
Extending humanity to other worlds in the Solar System is at the very limits of our modern technology. Extending humanity to other worlds in the Solar System is at the very limits of our modern technology. And unless there are dramatic discoveries in new propulsion systems or we learn how to build everything out of carbon nanotubes, the future of space exploration is going to require living off the land.
Astronomers have finally solved one of the outstanding mysteries in cosmology. Forget about all the dark matter and dark energy, where’s all the missing regular mass in the Universe? This has been called the “missing baryon problem”.
Why does life rely on water? Couldn’t there be lifeforms which are completely different from life on Earth? Isn’t that the textbook definition of alien?
It’s amazing to think there are telescopes up in space, right now, directing their gaze at distant objects. It’s all thanks to the technology of reaction wheels and gyroscopes. Let’s talk about how they work, how they’re different, and how their failure has ended missions in the past.
The distances to other stars are depressingly enormous. Fortunately, the Milky Way has got our back. Other star systems have been hurling comets and asteroids towards the Solar System. All we’ve got to do… is catch them.
This week Fraser Cain discuss about Fermi Paradox. How difficult it would be for aliens traveling at 10% the speed of light to settle the entire Milky Way, and it turns out, it's not as simple as you might think.
In order to really survive and thrive in space, we’ve got to learn to live off the land, to acquire the resources in space that will allow us to survive… in space. We’ve got to learn to turn those raw materials into forms we need: fuel, breathable air, water, construction materials, and eventually even finished goods like rocket parts and electronics.
NASA’s Hubble Space Telescope launched on April 24, 1990, and it’s been hard at work ever since, studying the cosmos like no other observatory in human history.
We’ve reached the third part of our series on Lagrange Points, those stable spots in the Solar System, where you can sort of hover with the minimum amount of fuel. In this episode we’re going to look at the L4 and L5 points which share the orbit with a more massive object.
Lagrange Points. Stable spots in space. What spacecraft work best in which places? What are some amazing ideas that could utilize these regions across the Solar System? This week, we’re going to talk about L2 and L3, the other meta-unstable spots that you can park a spacecraft at.
Thanks to gravity, there are places across the Solar System which are nicely balanced. They’re called Lagrange Points. Various spacecraft have already visited Lagrange Points, used them for some or all of their missions. Let’s explore the Lagrange Points.
Whenever I mention dark matter in anyway in the Guide to Space, or in a questions show, I get a bunch of responses that have essentially the same point. Astronomers are just speculating, why do they even think dark matter is a thing?
It’s too bad Mars is such an interesting place, because it’s actually one of the most difficult places to visit in the Solar System, especially if you want to bring along a lot of luggage. That planet is a graveyard of missions that didn’t quite make it.
Fraser gives 5 answers to the question, “why should we explore space when we have so many problems here on Earth?"
The far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earth’s constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe.
As astronomers and engineers design the next generation of giant space telescopes, they’re running up against the limits of current launch providers. To go bigger, space agencies will need to consider assembling their next-generation space telescopes… in space.
Earth is the best planet in the Universe. No matter where we go, we’ll never find a planet that’s a better home to Earth life than Earth. However, is it the best planet? More at #365DaysOfAstro
ESA’s Solar Orbiter and NASA’s Parker Solar Probe will measure the Sun from every angle up close, providing detailed images and insights of our closest star, to help understand how it creates and controls the giant bubble of plasma that surrounds the entire Solar System.
Over the coming decades, more and more of our space-based infrastructure will be built in space, manufactured out of materials that were mined in space. In order to achieve that space future, engineers and mission planners will need to design and construct the technology that will make this possible. That means testing out new prototypes, technologies and methodologies for mining and space-based manufacturing.
After James Webb Space Telescope, there's LUVOIR, but what come after? Let’s have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes.
Humans to Mars. That’s the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. But there are two places humans can go which are a stepping stone between Earth and Mars. Phobos & Deimos.
With so much attention on Mars, we tend to forget there's another Earth's twin. Venus. What’s on the Surface of Venus? More about the history of Venera Program at #365DaysOfAstro
Astronomers working with the NASA’s Chandra X-Ray Observatory and ESA’s XMM-Newton have developed a technique to watch quasars and track the expansion of the Universe. More at #365DaysOfAstro
The total number of confirmed exoplanets are more than 4000. So let’s run the clock forward and try to calculate what the future holds for exoplanets. How many worlds will we know about 3 decades from now, in the year 2050?
If spacecraft, rovers or even astronauts make the momentous discovery of life on another world, that’ll just open up new questions. Did it originate all on its own, completely independently from Earth, or are we somehow related?
The European Space Agency announced their plans to build a comet interceptor. A spacecraft that will lurk out at the Earth-Sun L2 Lagrange point, waiting for a long-period comet or interstellar object to pounce on, and give us the first close up view ever.
How humanity will react if we discover life somewhere out there in the Universe, whether it’s bacteria under the surface of Mars, a biosignature of alien life in the atmosphere of another world, or a radio signal from another civilization?
When we send anything to space, we have to pay an enormous amount of money. But what about building an enormous structures in space with 3D Printing?
