Those aren’t Dyson Spheres they’re hotDOGs, the best gravitational lens in the Universe, new Starlinks are really bright in the radio, and SpaceX recovers its SuperHeavy.
Are we alone in the Universe? Probably, one of the most important questions one can ask. So, how are we currently trying to answer it and what happens when we finally do?
What happens if astronauts throw stuff from orbit? Can we travel through a black hole? What is our Sun's place in the Milky Way? How can human spaceflight become profitable? Answering all these questions and more in this week's Q&A show.
Could we repair missions like JWST and Gaia? Polaris Dawn returns to Earth, did Earth once have rings? and a peanut-shaped asteroid just drifted past Earth.
This is an unusual interview for my channel. It's mostly about AI, our current developments and the threats it poses to us.
What's the maximum speed you can get from a gravity assist? Can we have a double gravitational lens? What do you need to do to a phone to sent it to space? Answering all these questions and more in this week's Q&A show.
Polaris Dawn launches and completes the first private spacewalk, the surface of a giant star is resolved with incredible detail, Starliner comes home empty, and amazing new images of Mercury from BepiColumbo.
Stars oscillate. Even the Sun does. And we can learn a lot about them by studying those oscillations. How is it done and what can we learn? Finding out in this interview. Guest: Dr. Marc Hon
What would it take to bring the Voyagers back to Earth? When will we see a true deep field by Webb? Why is Europa Clipper solar-powered? Why do black holes rotate? Answering all these questions and more in this week's Q&A show.
Another asteroid hit exactly where astronomers predicted, a monster asteroid rolled Ganymede over onto its side, strange sounds coming from Starliner, and China announces when it’ll try to grab a piece of Mars.
Interferometers are a great tool for getting incredible resolution without building giant mirrors. Why don't all telescopes use it? What projects should we expect and what could we get from them? What are the challenges? Finding out in this interview! Guest: Dr. Gerard van Belle
Could entangled electrons be used for FTL communications? Will Starship enable better satellites? Could we detect radiation on another world? Are there alternative explanations for black holes? Answering all these questions and more in this week's Overtime Q&A.
Is Betelgeuse a binary star? Starliner is coming home empty. New Glenn is on schedule to launch NASA’s next mission to Mars. NASA’s solar sail unfurls.
Why does the Sun have an 11-year cycle? Would I rather have a Venus mission or a Jovian moon mission? Do black holes attract other black holes? Can Chinese astronomers use Hubble/Webb? Answering all these questions and more in this week's Overtime Q&A.
The DART mission is going to create a meteor shower on Earth, an explanation for the Wow! Signal, big problems with New Glenn, and JUICE completes a flyby of both the Earth and Moon.
Have I ever messed up a recording? Are there plans for new space stations? Is there a limit to the size of an orbital rocket? Will humanity survive the next mass extinction event? Answering all these questions and more in this week's Overtime Q&A.
The quest to find an Earth-sized planet around a Sun-like star continues. One of the telescopes that could achieve it is ESA's Plato mission. How will it be able to do it and what should we expect from it? Finding out it this interview. Guest: Dr. David Brown
Vast amounts of water found on Mars, but there’s a catch, Milky Way and Andromeda might not merge after all, a planet found before it gets destroyed, and an easier way to terraform Mars.
The final parsec problem is a mystery that is yet to be answered by cosmology. On paper, supermassive black holes shouldn't merge. But yet they do. Why is it happening? What helps them slow down? Could it be dark matter? Looking for answers in this interview. Guest: Dr. Gonzalo Alonso Álvarez
What's the most challenging part of Astronomy? What happened to Uranus? Which telescope to get for $200? Could we detect Voyager-like spacecraft flying through the solar system? Answering all these questions and more in this week's Q&A.
Interstellar travel might not be as impossible as most people think. Especially if we adopt the multi-stage approach that we already use in everyday rockets. How can we do it and what results we can expect? Finding out in this interview. Guest: Jeff Greason
It’s time for the Perseids meteor shower, Gaia has found hundreds of asteroid moons, Starliner is still in question, and where does the Moon’s atmosphere come from?
Future telescopes like Vera Rubin and Nancy Grace Roman will generate a lot of data. This will be a big challenge. To get ready for it astronomers use simulated observation data. Why is it important and how is it done? Finding out in this interview.
What happens to the stuff that falls into black holes? Do supergiants have sunspots? How can you do a gravitational slingshot from the Sun? Answering all these questions and more in this week's Overtime Q&A.
TRAPPIST-1 is one of the most interesting systems out there. JWST did observe them but we still don't have the results from all of them. Why is that and when can we expect to know something about their atmospheres? Finding out in this interview.
We’ve learned much more from the DART mission, dark oxygen is being generated at the bottom of the ocean, Starliner is almost ready to come home, and we might not need to dig deep to find life on Europa.
John Michael Godier and Universe Today's Fraser Cain discuss the exciting developments in space exploration, focusing on Spacex and the upcoming fifth test launch of Starship. Join us as we discuss the details, analyzing the performance, challenges, and future implications of SpaceX's ambitious project.
What happened at the earliest stages of the Universe and what is it expanding into? Can they just put a telescope inside a Starship? Why do I like the NIAC program so much? Answering all these questions and much more in this week's episode of Overtime Q&A.
Fluids behave very differently in space. We can make good use of it. For example, a recent NIAC grant was awarded to investigate a Magnetohydrodynamic Drive for Hydrogen and Oxygen Production in Mars Transfer. This is a system that should provide breathing oxygen for a journey to Mars made out of water with no moving parts in it. 🟣 Guest: Dr Alvaro Romero-Calvo https://ae.gatech.edu/directory/person/alvaro-romero-calvo 👉 More about the NIAC project: https://www.nasa.gov/general/magnetohydrodyn...
