Just a warning, the holidays are rapidly approaching. It’s time, once again, to think about what to buy all the space nerds on your lists. Here’s what we like.
Ep. 650: First Light for JWST
Well, this is it, we’re finally going to talk about the James Webb Space Telescope. After decades of development, delays and budget creep, the powerful infrared observatory is at its final home at the L2 Lagrange Point. Yesterday we saw the first scientific images from the telescope, and according to Pamela’s rules, we’re finally allowed to talk about it.
Ep. 605: Sounding Rockets
Last week we talked about balloon-based astronomy. This week we’re going to talk about putting balloons on rockets and making observations mid-flight. Welcome to the world of sounding rockets.
Ep. 599: Zodiacal Light
Pamela has told us in the most flowery terms about the diffuse dust across inner solar system. Leftover from the formation the inner planets. Well, it turns out, she was wrong. Super wrong. Time to update.
Ep. 526: Event Horizon Telescope and the Black Hole at M87
Today, of course, we’re going to talk about the announcement from the Event Horizon Telescope and the first photograph of a black hole’s event horizon.
Ep. 492: Comets, Asteroids and KBO's
Another topic with plenty of updates. Since we started Astronomy Cast we’ve visited many smaller objects in the Solar System up close, from Ceres and Vesta to Pluto, not to mention a comet. What have we learned?
Ep. 475: Fast Radio Bursts
You know what’s fun? Mysteries. Here’s one: fast radio bursts. Astronomers have been detecting mysterious one-time signals from across the sky. What’s causing them? Nobody knows for sure, but the search is on to get to the bottom of them.
Ep. 463: Pareidolia and the Moon
Have you seen the “Man in the Moon”? Pareidolia is your mind’s way of helping you make sense of the world, but doesn’t always match reality.
Ep. 452: Summer Observing Challenges
Summer is almost here, and for the northern hemisphere, that means warm nights for observing. But what to observe? We’re here with a list of events and targets for you to enjoy over the summer. Get your calendars handy, and start organizing some events with your friends, and then get out there!
Ep. 448: Prepping for the Eclipse
On Monday, August 21, 2017, there’s going to be a total eclipse of the Sun, visible to path that goes right through the middle of the United States. You should be making plans to see this, and we’re here to help you know where to go and what to do.
Ep. 416: Fireballs from the Sky!
Every now and then we look up and see bright fiery balls falling from the sky. Don’t panic, these are just bolides. Sometimes they leave trails, sometimes they explode, and sometimes they survive all the way to the ground.
Ep. 411: Science of Sunset Colors
We all enjoy beautiful, multicolored sunsets. But what causes the brilliant oranges, pinks and purples that we see, and why does it change from day to day and season to season?
Ep. 354: Comet Siding Spring vs. Mars
We were witness to a once in a million year event. A close approach of Comet Siding Spring to the Planet Mars. And fortunately, humanity had a fleet of spacecraft orbiting the Red Planet, ready to capture this monumental event in real time. What did we see? What will we learn?
