Astronomers Stunned by a Tiny World With an Atmosphere

The World, the Universe and Us ·

2026/05/06

Episode 366A Pluto-sized object in the outer solar system has shocked scientists. It’s so tiny that it shouldn’t have an atmosphere - but it does. Object 2002 XV93, known as a plutino, is a small rock floating about in the Kuiper belt - a doughnut-shaped region of icy objects out near Pluto. What’s surprising is that many dwarf planets bigger than this object can’t hold an atmosphere, so it’s a mystery how this is even possible. This discovery comes as the decades-long debate about Pluto begins

2026/05/01

Episode 365Craig Venter, one of the world’s most influential geneticists, has died aged 79. He leaves behind an incredible - and complicated - legacy. Venter is primarily known for playing a leading role in the sequencing of the human genome. Later he pioneered the field of synthetic biology, creating what was described as the first synthetic life form - a feat that was not without controversy. So what drove Venter? And why was he so compelled to promote the idea of science as a competitive

Episode 364 Global temperatures are rising faster than ever - and with a strong El Niño on the way, scientists are warning we could temporarily breach 2°C of warming above pre-industrial levels. While other models suggest it may only hit 1.75°C, either option is bad news for the climate. The European state of the climate report has just been released, painting a picture of a rapidly warming world. Temperatures in Europe are rising faster than any other continent - and places like Iceland, Norway

2026/04/23

Episode 362It’s been 40 years since the world’s worst nuclear disaster unfolded. Since the explosion at Chernobyl in 1986, the world has feared nuclear power - and the widespread damage it can do. But are we right to fear it? Though it’s left a lasting scar on the region, nuclear power is still safer than fossil fuels - which kill millions of people each year. So what will it take to change public opinion? We examine the lasting impact of nuclear fallout on Chernobyl - and how things have changed

2026/04/20

Episode 361 The Earth is about to enter an extremely strong climate phase that could cause major disruption on a planet-wide scale. This “super El Niño” - or “Godzilla El Niño” - threatens to make 2027 the hottest year on record. If it’s as strong as scientists fear, the weather event will bring droughts to some areas of the world and floods to others, causing food shortages and billions of pounds of damage. And with the world already warming faster due to human activity, the effects will only be

2026/04/10

Episode 359DNA analysis of 10 Neanderthal people is shedding light on why their populations declined 75,000 years ago - eventually leading to their extinction. After being hit by a cold spell, we can see Neanderthals lost a lot of genetic diversity as their numbers dwindled. Living in small, isolated groups, we see evidence in both genetic and archaeological evidence that this pushed the human species to die out. One exception to this trend is Thorin - known as the last Neanderthal. We explore

Episode 358The male G-spot exists - and scientists have found it. The most comprehensive study of the human penis has identified one specific location most involved in sexual pleasure - and it’s not what science thought. 14 penis slices from deceased donors were inspected under the microscope - and one region in particular was packed with nerve endings. Medical literature has long thought a different region was home to the most nerves, but this new finding debunks the old textbooks. Now we know

2026/03/27

Episode 356A truck carrying antimatter has been driving around the campus at CERN, home of the Large Hadron Collider. But why are scientists transporting this delicate and extremely expensive substance? Antimatter is regular matter’s counterpart, first theorised in the 1920s. Producing and storing it has proved difficult, as it’s prone to annihilating the moment it meets its opposite half. But CERN scientists found a way - and it’s the only facility on Earth able to create these

2026/03/25

Episode 355 An entire pig’s brain has been preserved after death, using a technique that will keep the structure of the brain intact - potentially for hundreds of years. Scientists say they will offer the treatment to terminally ill humans, in the hopes that one day, in the distant future, we’ll be able to reconstruct their minds and bring them back to life. Because of the speed at which scientists need to preserve the brain tissue, the method will only work on people who opt in for assisted

Episode 352Notwithstanding President Trump’s efforts to slow the growth of renewable energy, the US/Israeli attack on Iran has given the green revolution a huge boost. In response to the war in Iran, the Islamic Republic has stopped almost all traffic in the Strait of Hormuz, a waterway through which one-fifth of global oil and one-fifth of seaborne gas supplies pass. They’ve also struck oil and gas fields with drones and missiles. This has given countries a much-needed wake-up call, showing

Episode 348Thought extinct for 6,000 years, two marsupial species have been discovered alive in New Guinea. Biologists have found a new genus of marsupial glider and the Pygmy Long-fingered Possum on a small Western part of the island. One biologist said this discovery was “more important than finding a living Thylacine in Tasmania”. Host Rowan Hooper is joined by Tim Flannery of the Australian Museum in Sydney, who led the team that confirmed the discovery. He tells us all about these quirky
