AstronomyCast 230: Christiaan Huygens

Astronomy Cast Ep. 681: Kilonovae by Fraser Cain & Dr. Pamela Gay Streamed live on May 7, 2023. In 2017, astronomers detected the gravitational waves and electromagnetic radiation from colliding neutron stars. This had been long theorized as one of the causes of a certain type of gamma-ray burst. By studying the event and its afterglow, astronomers have learned a tremendous amount about the formation of the heaviest elements in the Universe.

Astronomy Cast Ep. 680: Rogue Black Holes by Fraser Cain & Dr. Pamela Gay Streamed live on May 1, 2023. Last week we talked about rogue stars. This week we're going to take things up a notch and talk about an even more extreme event. Rogue black holes. Astronomers recently discovered a supermassive black hole on an escape trajectory, leaving newly forming stars in its wake. It's wonderful, terrible, nightmare fuel. Fraser's rogue SMBH article: https://www.universetoday.com/160072/astronomers-spot-a-rogue-supermassive-black-hole-hurtling-through-space-leaving-star-formation-in-its-wake/ The original paper: https://arxiv.org/pdf/2302.04888.pdf This video was made possible by the following Patreon members: Burry Gowen Stephen Veit Jordan Young Venkatesh Chary Andrew Poelstra Brian Cagle David Truog THANK YOU! - Fraser and Dr. Pamela

Astronomy Cast Ep. 679: High(per) Velocity Stars by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 24, 2023. Most stars in the Milky Way are trapped in here with us, doomed to orbit around and around and around. But a few have found a way out, an escape into the freedom of intergalactic space. How do stars reach escape velocity, never to return?

Astronomy Cast Ep. 677: The Answer is Always Dust by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 10, 2023. Whenever astronomers discover something surprising, the answer often turns out to be dust. Dust obscuring our view, dust changing the polarity, dust warming things up, dust cooling things down. It's always dust. Until it isn't.

Astronomy Cast Ep. 676: Other Things With Rings by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 3, 2023. We've spent a lot of time gushing about Saturn's rings, but there are other places with ring systems. And not just Jupiter and the ice giants, but asteroids, dwarf planets, centaurs and even exoplanets. Today let's gush about them!

Astronomy Cast Ep. 675: Exotic Forms of Ice by Fraser Cain & Dr. Pamela Gay Ice is ice, right? You know, what you get when water freezes. Well, maybe here on Earth. But across the Universe, water can be squeezed together at different temperatures and pressures, leading to very different structures. Today we'll talk about the different forms that ice can take.

Astronomy Cast Ep. 674: Asteroid Early Warning Systems by Fraser Cain & Dr. Pamela Gay The asteroid apocalypse is one of those existential crises that keep astronomers up at night. But the DART mission showed us that we can push an asteroid off its trajectory if we have enough warning. Today we'll talk about how humanity is building early warning systems to give us time to respond to a dangerous asteroid.
