Planet Formation is (Still) Not Well Understood

One of our recurring topics is ?Planet formation is not well understood,? and a trio of new papers is making it clear why planet formation continues to... not be well understood. Put simply: the universe likes to create more diverse solar systems than an entire planet?s worth of sci-fi writers can imagine.

SPECIAL SHORT: How NASA Budget Cuts Will Hurt Space Science

Earlier in March, Congress voted into place the FY2024 budgets for multiple agencies, including NASA. The agency is being asked for an overall 2% cut. Combined with inflation rates over 3%, we are looking at a fairly significant cut to the U.S. budget for space science. Dr. Pamela Gay breaks down what these cuts will affect, including people and missions, as we move forward with this already stressful fiscal year. (This episode was recorded on March 14, 2024)

Stability, Instability, Drama, and How We are Space Stuff

It is possible to buy stickers, sweatshirts, mugs, and other stuff and things emblazoned with the simple phrase, ?We are star stuff?. This phrase was popularized by Carl Sagan, and it serves as a gentle reminder that all the complex atoms - by which I mean most everything heavier than helium - found their start either in the nuclear core of a star or in the nuclear explosions of a dying star or stars. But, as with so many things, the truth is much more complicated than the meme.

Early Black Holes Formed Before Stars?

One of the unexpected realities of JWST is the discovery that we have really been asking the wrong questions in many astronomy areas. For instance: we generally asked how supermassive black holes and galaxies formed, with a basic assumption that these things happened in some interrelated process. We thought stellar mass black holes came from stars and that there might have been tiny primordial black holes that evaporated away, but that was it. Closed case. Black holes formed with all the normal structures we experience today. Except that now, JWST?s observations require us to find a way to accelerate the formation of those structures, and one way to do that is to seed the universe with black holes.

Yes, Scientists DO Look at the (Dark Energy Survey) Data

Every time I get the digital ?why can?t you scientists just look at the data? lecture, I wonder what people think scientists do. All we do is look at data, and when that data tells us our understanding of the universe is wrong, we?re pretty good at accepting the data and throwing out our false understandings? even when the data makes our life a whole lot harder. Such is the case with the accelerating rate of expansion of the Universe...

Celebrating the Mars Robots that Could

Robots on Mars have a long history of exceeding all possible expectations. From Spirit and Opportunity lasting far beyond their planned 90-day missions to Ingenuity lasting 72 flights out of a planned five, these craft have become so beloved that we mourn their missions ending. Today, while we recognize NASA's Day of Remembrance, we also celebrate all the Mars missions that have done more than expected.

The Compass (Sometimes... Kinda) Points North

If you take a compass and follow its pointy little needle, you will end up in Northern Canada but not at the North Pole. If you have a boat, you'll end up on Ellesmere Island wondering where Santa is hiding. The fact that the rotational north pole of the Earth and the magnetic pole of the Earth don?t align means that if you want to actually get to the Earth?s rotational North Pole - the one the pole sticks out of on your globe - you have to look up corrections online and veer a little bit in whatever direction the correction happens to be at the moment. And if you are catching this show sometime far, far in the future, then Ellesmere Island that is true in early 2024 is likely no longer true.

Spooky Season Space Images

From October 25, 2023: Around our parent collaboration, CosmoQuest, Halloween is, hands-down, the most beloved season of the year. Costumes are worn. Yards are decorated. We are here for all the strangers that knock on our door - the weirdos, the witches, and the oh-so-many werewolves - and there will be as much candy as we can afford given out. We know we are not the only ones. With about a week to go, we know that any day now, NASA, ESA, ESO, and others will begin releasing their spooky season images. There will be nebulae cropped with the contrast adjusted just so to reveal witches' hats, and others rotated to reveal ghosts and maybe - I can hope - a goblin or two.

Making Anti-Matter... Matter

In this episode, we look at what tree rings can teach us about past earthquakes, and how well machine learning can identify life, like trees, from carbon-rich materials that were never alive to distant galaxies and spinning black holes. We even take a deep dive into anti-matter, but not a literal deep dive? just a conceptual deep dive.

Blast From the Past: Watch the Annular Eclipse on October 14!

When we headed into recording this episode, I didn?t know if there would be a government shutdown or not, and I have to admit, on Saturday, September 30, I spent more than a few hours binge-watching TV shows while frequently updating my news feeds. This episode would have looked very different with a shutdown. Since we got a budget, today?s episode focuses on science. In the first segment, I get to talk about something I never thought I?d even read about -- the effects of spawning anchovies on energy dissipation in the ocean. Along with that fishy story, we have news from the Mars rovers, pretty images, and information on watching the October 14th annular eclipse.

Solar Cycle to the Maximum, 2025

Researchers currently think solar maximum - when the Sun is most active - will occur sometime in late 2024 to early 2025. With this cycle, we will experience just what a good blast of solar radiation can do to the small sats, CanSats, and other satellites in low-earth orbit. If history is to be listened to, it?s only a matter of time before a solar event wreaks havoc on satellites and our ground-based society.

It's Not Aliens (We Also Want Aliens)

There are some news cycles that are just plain weird, and this news cycle tried really, really hard to be one of them. Headlines last week highlighted that JWST observed methane and carbon dioxide in the atmosphere of a planet, which is entirely true. This headline was followed by stories that the reason could be aliens? and there is not enough data to be aliens. We want there to be definitive signs of life on other worlds. We want to know that life is common. We want the universe to thrive with societies capable of art, exploration, empathy, and science. We want our universe to not be a tremendous waste of space. And it is really frustrating to see these stories that inevitably imply that researchers are trying to cover up the truth. We?re not; we?re impatiently waiting for there to be enough evidence that we can say, yes, there is life out there among the stars. And that evidence isn?t here.

The Volcano That Could... But Didn't

Dr. Pamela is big on volcanoes, and she hoped we?d have an awesome new eruption to report, but we don't. There is, however, still a lot of news this week that doesn?t include an Iceland eruption. Instead, the news includes the first images from a new spacecraft, updates on Lucy?s discovery of a contact binary, and more on the OSIRIS-REx sample return.

More (Failed) Observations of Dark Matter

In this week's episode, we look at the upcoming solar maximum, how solar activity affects Neptune, the robotic invasion fleet on Mars, and how some of the weirdest star systems in reality have been able to form. In our closer look, we fail to see dark matter - like everyone - but observe its gravitational impact on light from objects we can see.

A River Runs Through It - Mars and Titan

This episode reminds you to look up, look out, and reflect on what we see around us. Stories cover a weird white dwarf that is doing things our Sun may do billions of years from now, how satellite images can now be used to measure river flows here and on Mars, and Titan, as well as the emerging field of planetary geoarcheology, that will help us understand just how long it will take for Mars rovers to become buried relics. And also climate change. Buckle up, the news isn't good. (This episode was originally released on YouTube August 9, 2023.)

Satellite Constellations and Early Warning Systems

According to satellite cataloger Jonathan McDowell, there are now 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites. This is a whole lot of missions to try and keep from colliding and all it takes is one particularly bad collision to transform the more than half-million objects from useful technologies to a shield of shrapnel that protects our universe from us by trapping us here. In our closer look today, we are going to look at early warning systems that are being developed, and how future - more highly mobile satellites, can both do good and create chaos.

Once and Future Life on Venus, Earth, and Mars

Each week, when we set off to do this show, we start with one core idea: We want to tell you what is new in space and astronomy? and remember Earth is a planet too. When we select stories, we try to find the ones we?re excited to talk about over coffee, or the ones we know we will be sharing randomly with strangers who make the mistake of asking, ?What do astronomers do?? We are here, week after week, to inflict space on others, and we hope that when we do you will return the favor and inflict this show on others.

Earth Science is Planetary Science

In this episode, we need to take one of our periodic looks at our planet's science and understand what it means to life as we know it. But we will only look at Earth for the first two segments. Then we?re going to race away to enjoy an interview by Beth Johnson with Dr. Kat Volk about the icy Trans-Neptunian Objects that fill the spaces around Neptune and beyond Pluto. In our final segment, we look at all the amazing - and in one case alarming - launch attempts of the past two weeks. (This episode was originally released on YouTube June 3, 2023.)

A New Space Race?

Space science isn?t where the money is? at least not yet. Astronomy and planetary science in the U.S. are funded by NASA, the National Science Foundation, and a variety of smaller foundations and extremely wealthy individuals. And this means that sometimes science can only advance at the speed Congress is willing to budget. The U.S. is in a new space race with China, and our ability to remain competitive in low-earth orbit is now an economic issue, with communications and imaging satellites powering multiple sectors. If a multi-year authorization is passed, there is hope folks will be able to dream, focus on research, and maybe, just maybe, spend less time asking for money.

While we could spend an entire episode on Earth, there is just too much going on in the universe to linger anywhere too long. From our world, we journey out to look at the super massive black hole in the core of M87, and then Beth Johnson will join us with an interview of the SETI Institute?s Dr Chenoa Tremblay and how radio astronomers are one step closer to simultaneously looking for life and doing science with the very large array. This interview highlights how advances in signal detection and processing will now allow researchers to both study the science of distant stars and look for potential signals of alien civilizations.

This episode features the kind of news week where we looked at the April 20th eclipse in the South Pacific and decided it just wasn?t a huge priority. Between watching Starship's ?will it won?t it? launch attempts and getting news of discoveries in cosmology and new software in planetary science? and the discovery of a totally weird rock formation on Mars? there is a lot going on out there. We?ll have a total eclipse on April 8, 2024. With that event occurring in less than a year, now is the time to start planning your travel if you want to see a transformative celestial experience.

In Venus VERITAS

For decades now, our planetary science news cycles have been dominated by Mars. Mars is relatively close, and we have a lot of experience landing there and science goals to pursue. But it has left our other closest neighbor, Venus, off the mission list. That is, until 2021, when NASA and the European Space Agency announced three separate but complimentary missions to that hellscape world. And now, one of those missions - VERITAS - is threatened to be completely mothballed before even really beginning. Later on in the show, Beth Johnson will interview deputy principal investigator, Darby Dyar, about why VERITAS is suddenly on the chopping block, what this means for planetary exploration, and how the public can help change NASA?s mind.

Humans are the ultimate pattern matchers - at least for now. I have to admit I?m looking forward to the day I can give some new AI a set of images and ask it to tell me what animals it can find among the nebulae. The software isn?t there yet? But we?re also going to take a closer look at how art and AI look at space.

The Search for Life on Other Worlds

Right now, humans are tantalizingly close to being able to search for life on other worlds where it is reasonable to think life could exist. We can?t do it yet - at least not in a way that would be safe for any potential life, but this is a long game, and as we?ll discuss in this episode, the technologies we need are being actively developed and tested on Earth, and the missions we need to find the best places to search are either already out there doing their job, or preparing to launch. This could happen, provided nothing happens to prevent us from getting off the planet? (This episode originally aired on television March 25, 2023.)

A new asteroid has been discovered with an orbit that crosses our own planet?s orbit. In general, this object and Earth are very good and not trying to occupy the same space at the same time, and we?ve managed to coexist for a fair amount of time. We are going to have a close approach, however, in 2046, and for the first time in a long time, the potentially dangerous asteroids list actually gave us something to worry about.

Is 2023 the Year of Io?

In general, the kind of year we?ll experience gets its label at the end of the year. 2005 was the year of the never-ending hurricane season. 2017 was the year we experienced an eclipse and lost Cassini. 2020 was the year satellite constellations went from a handful to hundreds of spacecraft. 2022 was the year of Mars exploration with Curiosity, Percy, Ginny, Insight, and Tianwen-1. Each year gets to define itself, and it is up to us to fight or embrace what that year brings us. This year, 2023, is still young, but I?m going to guess that come January 2024, this will be the year of Io. (This episode originally aired on television March 11, 2023)

Space science potpourri and a more hopeful look at climate change

This episode has a little bit of everything as we bring you results from astronomers, geoscientists, climate scientists, imaging scientists, glaciologists, meteorologists, planetary scientists, engineers, and even bioarchaeologists. This diversity of research allows us to better understand our world and beyond. In our first segment, we look at how our ecosystem and past cultures rebounded after prior naturally occurring climate events. It's unclear if this research will help us better recover from the climate change we're currently facing, but maybe it will give us hope. From our world, we travel outward, looking at the meteorology of Mars, future technology for space exploration, and the star catalogs that will help us define our place in space.
