Deep Astronomy - The Earth As An Exoplanet

The 365 Days of Astronomy ·

2025/07/29

https://www.youtube.com/watch?v=s8omjQrl2f4 Hosted by Tony Darnell. From August 22, 2018. Are we alone? How unique is our Earth? Should the hunt for life beyond Earth uncover a multitude of habitable worlds and few (if any) inhabited ones, humanity would begin to understand just how lonely and fragile our situation is. On the other hand, if our hunt yields a true diversity of inhabited worlds, then we would learn something fundamental about the commonality of life in the cosmos. Like this

http://www.astronomycast.com/archive/ From November 13, 2006. You hear distances all the time in astronomy. This star is 10 light-years away; that galaxy is 50 million light-years away; that Big Bang over there happened 13.7 billion years ago. But how did astronomers actually figure out how far away everything is? It’s not a single measuring stick. Instead, astronomers have built up a series of overlapping measuring tools (yes, we’re calling supernovae and variable stars “tools”), which take us from

Hosted by Richard Drumm, your editor! Planets don’t just pop out of nowhere, fully formed and ready for astronomers to study. First, they begin as tiny little specks of dust, forming inside the clouds of gas around baby stars, which are known as protoplanetary discs. These dusty specks condense from the hottest parts of the cloud, kinda like the way raindrops form inside rainclouds. Over time, the specks of dust collide and stick together, forming rocky pebbles. When enough of these pebbles clump

Cheap Astronomy Ep. 121: Black Holes Yet Again!

The 365 Days of Astronomy ·

2025/07/23

Very dense and podcastable. Cheap Astronomy finds there can never be too many podcasts about black holes. Dear Cheap Astronomy – What are squeezars? Squeezars are stars that orbit supermassive black holes. Essentially they are stars on a slow death spiral into the black hole and the squeezing referred to is the tidal stretch being exerted upon them as the orbit closer and closer to the black hole’s event horizon. That tidal stretching heats them up, a bit like how the moon of Io, orbiting close to

Astronomy Cast Ep. 277: Orbit

The 365 Days of Astronomy ·

2025/07/21

From October 22, 2012. When an object is orbiting the Earth, it’s really falling. The trick, described in the Hitchhiker’s Guide to the Galaxy, is how to throw yourself at the ground and miss. There are several different kinds of orbits, and they are good for different reasons. From suborbital jumps to geostationary orbit, time to learn everything there is to know about going around and around and around.

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 Telescope is in the final stages of testing, and WFIRST (Nancy Grace Roman) is waiting in the wings. You’ll be glad to know there are even more

They have discovered thousands of exoplanets. And some of them are located in the habitable zone of their star, which means that liquid water could exist on their surface and is essential for life as we know it. The search for life however, is a little more involved than finding planets, measuring their location and
