We’re nearly at the 40th anniversary of the launch of NASA’s Voyager spacecraft. And they’re still going! Let’s remember these amazing missions. Support Universe Today Podcast
The Van Allen Belts surround the Earth with deadly radiation. What can we do to get past them and escape into deep space? Support Universe Today Podcast
In part 2 of this series, we look at the supertelescopes heading to space in the next few decades. Support Universe Today Podcast
Astronomy is about to get much much more exciting, with a whole new class of enormous telescopes developed on Earth and in space. How much more powerful? What will we be able to see? Support Universe Today Podcast
It’s a mystery that’s puzzled astronomers for years. Which came first, supermassive black holes or the galaxies that surround them? Support Universe Today Podcast
In this week’s question show, Fraser wonders if science is the best tool we’ve got, if communicating with aliens is a wise idea, and how he feels about people falling asleep to his videos. Support Universe Today Podcast
In this week’s question show, Fraser answers questions about dark matter black holes, the magnetospheres of exoplanets and whether the Earth is increasing or decreasing in mass. Support Universe Today Podcast
In this week’s QA, Fraser worries about artificial super intelligence, getting flung out of the Milky Way. Support Universe Today Podcast
North America is preparing itself for the August Eclipse, so we thought it would be a good time to explain how eclipses work and what’s going on as the Moon briefly destroys the Sun. Support Universe Today Podcast
Once we know where all the dangerous asteroids are, how do we prevent one from hitting Earth? Support Universe Today Podcast
We know we live in a cosmic shooting gallery. Who’s got their eyes on the sky, and how will we prevent an asteroid strike if we find a dangerous space rock? Support Universe Today Podcast
NASA is working on the most powerful rocket ever built: the Space Launch System. What could it be used for to explore the Solar System? Support Universe Today Podcast
In this week’s questions show, Fraser explains how the Apollo astronauts got past the Van Allen Belt, bulking up brown dwarfs, and how to deal with conspiracy theories. Support Universe Today Podcast
In this week’s QA, Fraser talks using an asteroid for a space ship, colonizing the whole galaxy, and whether you’ve got dark matter all around you. Support Universe Today Podcast
It’s been half a century since humans first set foot on the Moon? Why haven’t we gone back? Will we ever go anywhere interesting in space? Support Universe Today Podcast
In this week’s QA, Fraser talks about black holes consuming dark matter, if traveling faster than light moves you backwards in time, and what those big pools under rockets are for. Support Universe Today Podcast
We’ve only seen Uranus and Neptune one time up close. There are now some mission ideas in the works that might take us back. Support Universe Today Podcast
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? Support Universe Today Podcast
In this week’s QA, Fraser talks about how spacecraft deal with orbital debris, the ethics of dismantling planets, the age of life in the Universe. With special guest answerer, Dr. Paul Matt Sutter. Support Universe Today Podcast
We’ve now had multiple detections of gravitational waves, opening up a whole new field: gravitational astronomy. We talk about the detections made so far, and how we can see the Universe in a whole new way. Support Universe Today Podcast
NASA is planning a mission to get as close as possible as we can to the Sun and reveal its mysteries. Support Universe Today Podcast
In this week’s QA, Fraser talks about how aliens might be testing our morality, traveling faster than light to go back in time, and alternatives to the Big Bang Theory. Support Universe Today Podcast
Fraser Cain and Isaac Arthur team up again to bring you another epic collaboration. This time, it’s a 2-part series of construction tips from an engineer from a Type 2 Civilization. In this episode, we harvest helium 3, mine the asteroids, and rearrange the Solar System. Support Universe Today Podcast
In this week’s QA, Fraser talks about capturing comets, finding Lagrange Points around black holes, and what would happen if you crashed a whole lot of oxygen into the Sun. Support Universe Today Podcast
Cosmologists tell us that the Universe is flat. It sure feels like 3-dimensions. What does this even mean, and how do we know it’s true? Support Universe Today Podcast
Owning land here on Earth is nice and legal. But what about a plot of land on the Moon or Mars? When can I buy some ice on Europa? Support Universe Today Podcast
In this week’s QA, Fraser talks about the Chinese space exploration efforts, rotating space stations with artificial gravity and why he’s always standing in a forest. Support Universe Today Podcast
The Big Bang was a tremendous theory, but it had a few problems. In 1980 Alan Guth developed the revolutionary theory of cosmic inflation, and astronomers have been looking for evidence to this day. Support Universe Today Podcast
The Sun uses its enormous mass to crush hydrogen into fusion, releasing enormous energy. How long will it be until we’ve got this energy source for Earth? Support Universe Today Podcast
In this week’s QA, Fraser proposes ways to destroy the Milky Way, wonders what might happen if a warp drive ship passes through a planet, and how you could keep a galaxy alive forever. Support Universe Today Podcast
