I’d say half the astronomy-related videos on YouTube are all about black holes. Clearly, they’re a fascinating topic, but they’re also a mystery. How do you observe something that can absorb all the radiation and matter falling onto them, and nothing can ever escape? How do we know they’re really there, and what are the best observations we can make? Today I’m joined by Dr. Paul Sutter, a cosmologist, and astrophysicist to talk about how we know black holes are really there and not just a figment of an astrophysicist’s imagination?

On Sunday, May 31st, 2020, a SpaceX Crew Dragon capsule carrying astronauts Robert Behnken and Douglas Hurley docked with the International Space Station. This was a tremendous accomplishment for SpaceX and NASA, giving the United States the capability of launching its own astronauts, and no longer relying on its Russian partners. This was the 5th time that US astronauts went into orbit on a new kind of space vehicle, following in the footsteps of Mercury, Gemini, Apollo, and the Space Shuttle.

When you’re out in space, water is the most precious resource you can get your hands on. It can be used for air, water, to grow food, radiation shielding, and most importantly, as the propellant for your spacecraft. Exploration of the Moon has revealed that there’s a tremendous amount of water ice locked into the regolith, but it’s probably very difficult to access. But there are also permanently shadowed craters at the Moon’s poles that could have more than enough water to support a permanently inhabitable station on the Moon. But it’s going to be tricky to get at, considering the fact that temperatures in the shadows plunge to -240 degrees Celsius, just 30 degrees above absolute zero.

The distances to other stars are depressingly enormous. Sure, it’s incredibly far to get to Mars, Jupiter, and even Pluto, but at least you can design a robotic spacecraft to make the journey and see the science results in your own lifetime. But in the case of other stars, interstellar flight times will take thousands and even tens of thousands of years to send just a robotic mission. 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.

The Moon orbits around the Earth. The Earth orbits around the Sun. And out in the distant Universe, astronomers have found a system that takes this logical progression to its most extreme. There’s a system where a supermassive black hole with millions of times the mass of the Sun orbits another black hole with billions of times the mass of the Sun. How astronomers discovered this incredible interaction took careful observations, imagination, and the hard work of the Spitzer Space Telescope, taken during its final years of operation.
