Ep. 600: Looking Ahead
03.29.2021
Today we are gonna gaze into the future of space and astronomy. What upcoming missions & events are we excited about?
Pamela has told us in the most flowery terms about the diffuse dust across the inner solar system left over from the formation of the inner planets. well, it turns out she was wrong. Super wrong. Time to update!
You've probably heard of dark matter and dark energy, but maybe you don't fully understand what they are. Or maybe the idea itself just rubs you the wrong way and you'd like to know why scientists think they can just ...
It's been a while since we checked to make sure the Universe was still expanding. Yeah, apparently, that's still a thing. But in the last few years powerful new telescopes and expansive surveys have given us much more knowledge about ...
You might be familiar with the cosmic microwave background, but that's just one of the background radiations that astronomers look at. Some are well known and cataloged. While others are just starting to be possible to see at all. All ...
This is gonna be another one of those evergreen topics where we come back again and again. Finding planets. Every time we talk about this now it seems like we've gained thousands of new planets. Well, buckle up! New techniques ...
Pamela is always loath to talk about spacecraft until the mission's in space and the science is rolling. NASA's Juno Mission just received a mission extension, adding Jupiter's moons to the menu. Now, finally, we can talk about Juno! [Ed. ...
Stars often come in groups of 2 or more. And if they're orbiting close enough to each other one star can feast on the other and when that happens, well, mayhem ensues!
Some of the most powerful explosions in the Universe are gamma-ray bursts, capable of blasting a beam of death half way across the galaxy. In just the last few years astronomers have discovered a tremendous amount about these blasts and ...
Remember the good old days when there were only a few thousand living and dead satellites? Well, those days are long over. We're now entering an era where there will be tens of thousands of satellites. Not to mention the ...
2024 can't come soon enough. You know, that's the year when humans will set foot on the Moon again. Now don't you roll your eyes! That's the plan. Unless the plan changes. But my point is, explorers going to the ...
We've talked about the Moon and its water many times here on Astronomy Cast, but there've been a bunch of big updates thanks to new research from NASA and others. Today we're gonna give you an update on the state ...
All eyes are on the Moon. We're going back, this time to stay, right? One of the best resources on the Moon will be the lava tubes that criss-cross the subsurface of the Moon. These can provide protection from space, ...
So the Moon is about to become a very busy place with multiple countries and private companies planning missions in the next few years. It's been decades since the Outer Space Treaty was negotiated. It's time for the Artemis Accords!
As scientists continue to explore the Earth. They're discovering life, surviving and even thriving in extreme environments. What hints can this give us about what we might find as we search for live on other worlds.
Astronomers are finding even more new extrasolar planets and they're starting to discover entirely new categories. There are classes of planets out there that we just don't have any analog here in the solar system. Let's talk about them!
So with a sample of asteroid Bennu firmly inside OSIRIS-REx's return capsule, it's time to bring this treasure home. So scientists can study the composition and history of the space rock. But it's not the only sample return mission out ...
This year's Nobel Prize in Physics was awarded to three brilliant researchers who worked out some of the secrets of black holes. Today we're going to talk about the chain of discoveries that led to this award.
Did you hear the news? Nobel prizes for Black Holes! Now, we know there are stellar mass black holes and supermassive black holes, but how do you get from one to the other? How do black holes get more massive?
Don't ever accuse us of not comprehensively covering every kind of exploding star. This week we gather up all the left over ways that stars partially or fully explode or don't. Probably. Enjoy!
So you think that a white dwarf star is the end of a stellar life, and it's all downhill from there, a long, slow cool down towards the end of everything. But in some situations even dead stars can get ...
I've got some bad news for you. Stars die. At some point in the next few billion years or so our Sun is going to start heating up, using up all the fuel in its core, and then eventually die, ...
So have you heard the news? Of course you have. Evidence of phosphene on Venus. Which could be a biosignature of life on our evil twin planet. There have been a lot of surprising stories about Venus, so let's get ...
Every 2 years or so Mars lines up nicely with the Earth. It takes only 2 minutes to communicate with the rovers. You can see the polar ice caps in a small telescope. And it's the best time to send ...
It's time once again for Astronomy Cast to go on hiatus. You've got a couple months on your own to explore the night sky. But before we say goodbye, we'd like to make a few suggestions.
As amateur astronomers, we curse the Moon every month. Seriously! Why doesn't someone get rid of that thing! This week, something occurred to us. What if we actually pointed our telescopes at the Moon? What would we see? The Lunar ...
We imagine the asteroid belt as a place where all the rocks hang out in the solar system. But there are 2 huge bands of asteroids that orbit the Sun with Jupiter called the Trojans. And soon we may actually ...
Not only have astronomers discovered thousands of exoplanets, but they're even starting to study the atmospheres of worlds thousands of light years away. What can we learn about these other worlds and maybe even signs of life.
We're all looking to the next generation of exoplanetary research where we get planets directly. But astronomers are already making great strides in directly observing newly forming planets help us understand how our solar system might have formed.
So we're familiar with regular binary stars. Two stars orbiting each other. Simple. Of course the Universe has come up with every combination of things orbiting other things, and this week we look at some extreme examples.
Discovering comets is one of the fields that amateurs can still make a regular contribution to astronomy. But more and more comets are getting found by spacecraft, automated systems and machine learning. This week we'll talk about how comets are ...
Every year, more and more people are making their way to space. Some private citizens have already gotten their astronaut wings, paying for a trip to space out of their own pocket. What are the ethical implications of this as ...
The key to surviving in space will be learning how to live off the land. Instead of carrying all your fuel, water and other resources from Earth, extract them locally at your destination. It's called in situ resource utilization, and ...
Space is really far away, so when you send a satellite out into the void, that's pretty much the last you're going to be able to work on it. And if anything goes wrong, too bad, you're out a satellite. ...
As everyone knows, the Universe owes us a bright comet. There have been a lot of promising candidates, but in the end, they always fail to live up to our expectations. Comets keep on breaking up with us.
565: When Worlds Collide Astronomy Cast 565: When Worlds Collide by Fraser Cain & Dr. Pamela Gay So much of our Solar System has been shaped by enormous collisions early on in our history. Seriously, the nature of every planet ...
Last month astronomers announced that they had detected a tiny asteroid that had been captured by the Earth's gravity well and had been sharing our orbit for a few years. Today, let's talk about the smallest moons in the Solar ...
White dwarfs are usually about 60% the mass of the Sun, so it was a bit of a surprise when astronomers found one that was almost exactly twice that. What happens when white dwarfs merge?
Pamela and Fraser discuss the implications of COVID-19 and it's changes on the world, and what we all can do during this time.
We lost a bright star here on planet Earth last week. NASA mathematician Katherine Johnson passed away at the age of 101, after an incredible career of helping humans land on the Moon. If you saw the movie Hidden Figures, ...
You might be surprised to hear that we've never done an episode of Astronomy Cast featuring Betelgeuse. Well, good news, this is that episode. Let's talk about the star, why it might be dimming, and what could happen if it ...
A brand new telescope has completed on Maui's Haleakala, and it has just one job: to watch the Sun in unprecedented detail. It's called the Daniel K. Inouye telescope, and the engineering involved to get this telescope operational are matched ...
We've been following this story for more than a decade, so it's great to finally have an answer to the question, why was supernova 2006gy so insanely bright? Astronomers originally thought it was an example of a supermassive star exploding, ...
On the one hand, red dwarfs are the longest lived stars in the Universe, the perfect place for life to hang out for trillions of years. On the other hand, they're tempestuous little balls of plasma, hurling out catastrophic flares ...
For the longest time astronomers could only study the skies with telescopes. But then new techniques and technologies were developed to help us see in different wavelengths. Now astronomers can study objects in both visible light, neutrinos, gravitational waves and ...
The other big issue at the AAS was the challenge that astronomy is going to face from all the new satellite constellations coming shortly. There are already 180 Starlinks in orbit, and thousands more are coming, not to mention the ...
This week we're live at the American Astronomical Society's 235th meeting in Honolulu, Hawai'i. We learned about new planets, black holes and star formation, but the big issue hanging over the whole conference is the protests and politics over the ...
It's hard to believe it, but we survived another trip around the Sun. Now it's time to take the whole journey all over again, but with new news. Let's take a look at some of the space and astronomy stories ...
Huge surveys of the sky are finding more and more planets, stars and galaxies. But they're also turning up strange objects astronomers have never seen before, like Boyajian's star. Today we're going to talk about some unusual objects astronomers have ...
Hi everyone, Producer Susie here. This weekend, December 21-23, 2019, we will be having our CosmoQuest Hangoutathon. For 40 straight hours, our team will be bringing you guests, science and fun live on our channel. We are raising money to ...
