How often do objects fall into the Sun? Why do some stars explode as novae, not as Type 1a supernovae? Can the US Army just donate NASA a Hubble 2? Will humans be living underground on Mars? Answering all these questions and more in this week's Q&A. Watch the video here (with no ads) or on YouTube:

We’re now weeks away from a nova, NASA is looking for new Mars Sample Return mission ideas, there’s frost on Olympus Mons, and watching asteroids collide in another star system.

What kind of science can we do with telescopes on the Moon? Giant radio dishes in craters, gravitational wave detectors, UV interferometers, and much more. How Starship will completely change this field and enable new opportunities. Guest: Dr. Martin Elvis https://cfa.harvard.edu/people/martin-elvis

SpaceX announces their new spacewalking suit, China is off to the Moon again, progress on Vera Rubin, and take a one-way trip into a black hole. Watch the video here (with no ads) or on YouTube: https://youtu.be/_OIfxkBc4-8 Planet 9 Updates // Vera Rubin Mirror // New SpaceX EVA Suit (Vimeo)

Does gravitational lensing affect the CMB? Can the Great Attractor solve the Hubble tension? Why don't we put a Deep Space Network antenna in space? What's the difference between a nova and a supernova? Answering all these questions and more in this week's Q&A show. Watch the video here (with no ads

How do we know that Psyche is a metal asteroid? Did primordial gravitational waves stretch when inflation happened? When do we finally get more Trappist-1 data from JWST? Can a dead star possibly reignite? Watch the video here (with no ads) or on YouTube: https://youtu.be/aUyevaUmAbo Here's a link t

Which things can go faster than light and what does it mean for Physics. Can quantum entanglement provide interstellar communication. Why NASA didn't believe in websites during the early internet era. How should scientists approach controversial ideas. Answering all these questions with Dr Robert Ne

A mind-bending JWST image of the Orion Nebula, filled with rogue planets. Seeing the cosmic web. An explanation for a massive star that just disappeared.

Is our galaxy's black hole still consuming stars? When will we finally figure out dark matter? Can James Webb last until it exhausts its fuel and not break before that? How should we name exoworlds? Answering all these questions and more in this week's Q&A show. Watch the video here (with no ads) or

In this week's questions show, I wonder if we'll have enough time to respond to an asteroid or comet, if we're going to fill the asteroid belt with space junk and if antimatter engines are the best way to explore space. Watch the video here: https://youtu.be/pJbMAcXgLS4 Of course, the big news on my

In the pristine icy environment of Antarctica, there’s a telescope, embedded into an ancient glacier. The telescope is observing the Universe, directly through the Earth, using a cubic kilometer of ice to capture elusive particles called neutrinos. These ghostlike particles are streaming from the Su

In this week's questions show, I explain why we don't know of any perfectly habitable worlds in the galaxy. Why we don't know if the Universe is finite or infinite, and why we call it "micro gravity" and not "zero gravity". Watch the video: https://youtu.be/OOzwppRhHLU Here's a link to Dr. Hossenfel

The Earth’s atmosphere keeps us safe from the harsh environment of space, but it also obscures our view into the cosmos. No matter how powerful a telescope you build, the turbulence of the atmosphere limits your resolution. But astronomers and engineers have an amazing technology that allows a teles

The Hubble Space Telescope has been in space for 28 years, producing some of the most beautiful and scientifically important images of the cosmos that humanity has ever taken. But let’s face it, Hubble is getting old, and it probably won’t be with us for too much longer. NASA’s James Webb Space Tele

Got any plans for March, 2019? Want to come to Costa Rica with me and Dr. Paul Sutter? https://www.astrotours.co/costarica Our next Astro Tour leaves for Costa Rica on March 2-10, 2019. We'll be going to San Jose, Guanacaste Beach, Monteverde Cloud Forest, Arenal Volcano and much more. And every nig

In this week's questions show, astronaut Mike Massimino answers a question about astronaut training, I wonder how we could survive if the Sun dies, and explain why the shuttle's fuel tank was first white and then changed to orange.

In just a few hours we're going to be doing a very special live QA with Dr. Alan Stern, the Principal Investigator with New Horizons and Dr. David Grinspoon, AKA, Dr. Funkyspoon. They just released a new book all about Pluto and New Horizons, and they'll be available for 30 minutes to take your ques

President Trump recently called for the creation of a space force to deal with the future warfighting in space. It turns out, this already exists, space is already well militarized. https://youtu.be/D894aUbW1YE (YouTube)

In this week's episode, Fraser talks about how you can support the creators you love, why NASA doesn't make duplicates of its spacecraft, and what binoculars he's using. Q&A 54: Why Doesn't NASA Mass Produce Spacecraft? and More... (YouTube)

One of my favorite creators is futurist Isaac Arthur, we've even done a few collaborations together. Never seen his stuff before? Check it out here: https://www.youtube.com/channel/UCZFipeZtQM5CKUjx6grh54g This week Isaac will be joining me for a live QA on YouTube. Got questions for us? Join us liv

We’re now entering the final days for NASA’s Kepler Space Telescope. It’s running out of fuel and already crippled by the loss of its reaction wheels. In just a few months NASA will shut it down for good. That is sad, but don’t worry, NASA’s next planet hunting spacecraft, the Transiting Exoplanet S

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. Where Are the Voyagers Now? Remembering the Amazing Voyager Missions (YouTube)

Hey everyone, Fraser here. I just wanted to let you know about a special event happening today, Monday April 24, 2017 at 12 pm Pacific Time. Twitch is having a science week, and I'm going to be participating with a bunch of live events. One event will be a COSMOS Marathon playing on Twitch.tv. Start
