Travel can do amazing things: broaden horizons, build relationships, and rejuvenate the soul. But often, those experiences come at a cost. This is Peak Travel, a new podcast from WHYY about how travel shapes communities in hot-spots around the world. We’ll share the wonder that comes with exploring new places, as well as the harm that our worst travel habits can cause. And we’ll try to figure out how we can do it better. Each episode transports you to a new destination. You’ll meet the people who call that place home, hear their stories, and come to understand how tourism has changed their everyday lives. Supported by rich, on-location sound from around the world, Peak Travel unpacks the $1.9 trillion travel industry and its impact on people and the planet.

At the end of September, NASA's DART mission was deliberately crashed into the asteroid Dimorphos. Not carelessness, but a deliberate act with a view to testing planetary defense. After all, if we discover something large heading towards Earth, we might want to be able to nudge it off course. Here in Wales, the Comet Chasers team took a diversion from observing comets to looking at Dimorphos with the Las Combres Observatory global network of telescopes. But they weren't the ones doing the observing - that work is done by school children and members of the public at festivals and the like. Team members Cai Stoddard-Jones, Helen Usher and Prof Paul Roche explain the purpose of the mission, what it's taught us, and what contribution the school students have been making to "help NASA".

Edward Gomez and Chris North discuss names going to Jupiter on the Europa Clipper mission, which is currently being assembled. Then there is a new cannibal star, suspected of eating its own planets, and the detection of new "Galactic Streams" of stars that all formed together but have since spread out through the Galaxy. Finally, we move onto planet formation and the detection of ices in forming planetary systems. But where does all that planet-forming material come from originally? Haley Gomez and Cosimo Inserra tell us about a new object that's changing our view of where all the dust in the Universe originates.…

Recorded in late October, Chris and Edward discuss recent proposals for an all-British mission to space, the launch of Psyche to...erm...Psyche, and Edward's involvement with the detection of something called a Synestia - planets bashing together. Cardiff University also hosted Prof Duncan Lorimer, who was jointly awarded the 2023 Shaw Prize for the detection of "Fast Radio Bursts". These mysterious cosmic events seemingly come form nowhere, but provide an intersting way of investigating energetic processes in the Universe. They also make a nice "dipstick of the Universe". Prof Lorimer spoke to Chris about their detection, what we're learning about them, and his career to date Contents: 00:00 British space mission 05:20 Psyche mission 10:15 Synestia and planet bashing 16:50 Prof Duncan Lorimer and Fast Radio Bursts…

Chris and Edward discuss some recent stories, such as tantalising possible (emphasis on the possible) detections by JWST of interesting molecules on an exoplanet which coul (emphasis on the could) indicate signs of life. There's also new data on Europa, also from JWST, showing carbon dioxide on its surface - what does this mean? And further afield, astronomers have used ALMA to measure magnetic fields in incredibly distant galaxies, opening a potential new way to study the early Universe.…

In 2020 astronomers spotted an object slowly getting brighter, but it wasn't until 2021 tha they quite understood how unusual it was. In 2021, they studied it in more detail, and found that it was something we don't think has ever been seen before. It was also the most energetic single event ever witnessed. Going by the catchy name of AT2021lwx, or simply "lwx" to its friends, this month we learn more about it. Dr Phil Wiseman, from University of Southampton, and Dr Cosimo Inserra, from Cardiff University, explain more. Elsewhere in the news, Chris North and Edward Gomez discuss how the JUICE mission has been jolting one of its antennas, the retirement of NASA's long-serving astronaut Peggy Whitson, and of course more from JWST.…

A news roundup of the last couple of months with Chris North and Edward Gomez. With a few failures - the SpaceX Starship launch, iSpace's moon landing and Virgin Galactic's bankruptcy, it might seem things are going wrong. But it's not all bad news - ESA's JUICE spacecraft has successfully launched on its way to Jupiter! Elsewhere in the Solar System, archives of data from the Magellan mission to Venus have revealed further evidence of a volcanic activity on the hard-to-reach surface of Earth's evil twin planet. And there's Phaethon, the unusual asteroid that is the source of the Geminid meteor shower, and about which the mystery has deepened. Much further afield, there's new research on what leads to quasars, the energetic "burps" of galaxies as their central black holes gorge themselves on infalling gas. And finally, there's the mystery of the "impossible galaxies" seen in one of JWST's first ever images, which turn out to be, well, less impossible!…

Black Holes: Saviours of the Universe? 56:59

hace 2 years56:59

56:59

In terms of what might be called “pure science”, there’s one topic that tends to get people excited, and that's black holes. A few weeks ago, in February 2023, a pair of papers came out that linked theories about black holes to dark energy – something we really don’t understand. If correct, this could mean that black holes, by their very nature, could explain the accelerating expansion of the Universe. Black holes, of course, are often mis-understood. To find out a little more about them, Chris spoke to Dr Becky Smethurst, from University of Oxford. We also get into a few of the details about what the research suggests might be is going on, with lead author Dr Duncan Farrah from the University of Hawaii. Finally, it's back to Becky, who is sceptical about these new results.…

In the last month there was a show of the Northern Lights - or aurora - visible from the UK. If you didn't get to see it (spoiler: neither did we!), then you might get a chance in the future if there's another outburst. Edward Gomez and Chris North discuss how to increase your chances of seeing them next time there's an alert. In science news, some new thoughts on how the Moon could have formed, and an intriguing (and controversial) story about how balck holes might - possibly - be the answer to the mystery of dark energy. Chris also continues the conversation started in the last episode with Dr Ian Harrison and Dr Bob Watson about observing the cosmic microwave background. This time we discuss the advantages and challenges of launching in to space, and the problems caused by increasing numbers of satellites. There's also a new observatory being built in Chile - the Simons Observatory - which will present a huge leap forward in ground-based observations of the early Universe.…

There's also an interesting supernova, the first exoplanet confirmation from JWST. Meanwhile, on Mars, does no news mean bad news for China's Zhurong rover? We also speak to Dr Ian Harrison, from Cardiff University, and Dr Bob Watson, from the University of Manchester, about the telescopes that are trying to unpick what happened at the dawn of time, by looking at the Universe's oldest light, and how a telescope in Tenerife is helping.…

The 25th December marks an anniversary in the world of astronomy (as well as Sir Isaac Newton's birthday, of course) - the launch of JWST, the infrared space telescope launched to explore the Universe in unprecedented detail. One year on from launch, Chris North and Edward Gomez look at a few of the results that have come in, on top of those we've covered previously. From our own solar system, to the birth of stars, and out towards the first galaxies, the results have covered a huge range of scales in both space and time. That's thanks to the remarkable scientific instruments onboard JWST, including cameras and spectrometers. But it's not just the formation of objects that it's looked at - JWST can give unique insights into the deaths of stars as well. Dr Mikako Matsuura and Dr Roger Wesson, both at Cardiff University, explain what they've been discovering about "planetary nebulae".…
