Feature Guest: William Rapin

Welcome to Sutton Island, here in the middle of a beautiful and rugged landscape consisting of shallow lakes filled with salts and minerals. It’s a common vista on this world, and while the world in question is not our home, ancient Mars may well have been someone’s home. Today we’re joined here at The Star Spot by William Rapin, with reports from the latest discoveries of the Mars Curiosity rover and why one of the Principal Investigators of NASA’s Viking mission is now convinced we found life on Mars back in the 1970s.

Amelia and Tony share exciting news: the most powerful radio dish telescope in the world will soon be ready for widespread astronomical use! Then Joseph excites even more with a stunning discovery: the presence of water in the atmosphere of an exoplanet, making it the most prominent target yet in the search for habitable worlds. And once again on the subject of habitable worlds, in her debut, Dunja wonders if the size of planets matters to their potential for being habitable. Finally, Amelia and Priyanka report on a remarkable new technique for estimating the mass of black holes!

The Hubble constant, which measures the expansion rate of the cosmos, may not be a constant after all, and if that’s true it means we’re missing something big in our understanding of the universe. Today we’re joined here at The Star Spot by Sherry Suyu, who leads the aptly named H0LiCOW project which uses the phenomenon of gravitationally lensed quasars to measure the expansion rate of the universe.

Feature Guest: Jorge Zuluaga

Astronomers have yet to confirm a single detection of an exomoon, that is a moon orbiting a planet outside our solar system. Now it turns out at least part of the explanation is that we may have been looking in the wrong place all this time. Introducing ploonets. No, I did not just mispronounce the word planet. Today we’re joined here at The Star Spot by Jorge Zuluaga, whose team coined the name to describe a moon that has gone rogue, and while it may sound exotic, a speculative theory posits that ploonets could have played a key role in the evolution of our very own planet.

Tony is back with an exciting discovery made in fresh snow in Antarctica: an isotope that can only have been manufactured in one place – the infernal heart of a supernova. Then Joseph and Tony once again ask the cosmic question: what are fast radio bursts, or FRBs, as eight more repeating FRBs have been detected in deep space, and we just may be on the cusp of solving the mystery. Finally, Amelia and Tony talk about a glitch. A software glitch? No. A neutron star glitch!

Feature Guest: Vikram Ravi

They come to us from deep space. They last a tiny fraction of a second. They contain as much energy as the sun’s total output in 80 years. Yet we still haven’t figured out what causes these so-called Fast Radio Bursts or FRBs. I don’t want to say it’s aliens, but, no, it’s probably not aliens. Today we’re joined here at The Star Spot by Professor Vikram Ravi whose team is quickly zeroing in on the origin of these bizarre FRBs.

Amelia and Tony explain new research stating that worlds with completely frozen oceans, fittingly known as snowball planets, may actually be habitable . . . on the surface! And while the peak of the prolific Perseid meteor shower may have already passed, Simon reminds us that it’s still not entirely over, and to get out there and take a look while you still can. Finally, robots are on the International Space Station! Joseph and Tony explain the purpose of three artificial helpers floating in the orbiting laboratory, one of which arrived only in late July.

Today we’re joined here at The Star Spot by science writer Dan Falk.

We’ll start today’s interview with a commemoration of the 50th anniversary of the landing of humans on the moon and the internationalism of that critical moment. But then, 50 years after this triumph of science, we’re going to confront head on a set of old and new challenges to the scientific enterprise itself.

All the fascinating research and discoveries we share at The Star Spot rests on basic assumptions about the primacy, scope and universality of science. In this two episode series, we take a step back and wrestle with some uncomfortable questions.

What if the fundamental reality we probe is merely a simulation? Does science harbour blind spots that will forever limit its ability to build a theory of everything? And even if science is supreme, can it contend with conspiracy theories and pseudoscience – like the moon landing hoax belief – that undermine its legitimacy in the eyes of the wider public.

Today we offer a best of from our vault here at The Star Spot. We dug back to a fan favourite, our December 2014 interview with Nobel laureate Brian Schmidt, who won the biggest prize in science for discovering the accelerating universe. 

The 1929 discovery of the expanding universe by Edwin Hubble forever changed our picture of the cosmos and our understanding of our place in the universe. In 1998 we learned that wasn’t the only surprise. That’s when two teams of astronomers announced that the expansion of our universe isn’t slowing down as everyone assumed. Its speeding up. Today we’re joined at The Star Spot by Distinguished Professor Brian Schmidt who won the Nobel Prize for discovering our accelerating universe.

Tony and Amelia discuss a new finding from the ALMA observatory: a cool ring of gas encircling the supermassive black hole at the center of the Galaxy. Then Simon pulls you in with the measurement of a tiny black hole at the center of a nearby dwarf galaxy. And finally Tony returns with breaking news from the Jovian satellite system: Sodium chloride, aka table salt, has been found on none other than the ice-covered ocean moon Europa!

Remember that nursery rhyme, “Up above the world so high, like a diamond in the sky?” Well they were on to something, because it turns out diamonds – albeit nanodiamonds – are ubiquitous across the Milky Way galaxy. So-called diamond dust is even here in our own solar system. Today we’re joined at The Star Spot by Professor Jane Greaves, whose team made the discovery that unexpectedly solved a long standing astronomical mystery.

Feature Guest: Cynthia Phillips

In the 1970s, the Viking landers performed historic experiments aimed at detecting life in the Martian soil. The results were disappointing although to this day still not entirely conclusive. Now over 40 years later a new lander with a next generation set of life detection equipment is under assessment by NASA. This time the target is not the Red Planet, but the ocean moon Europa, which has emerged as a prime candidate in the search for life in the solar system. Today we’re joined here at The Star Spot by Cynthia Phillips, Deputy Project Scientist for the Europa Lander mission concept, who tantalizes us with dreams of flying through plumes and digging into an icy crust.

Tony goes into speculation mode and ponders the chances that interstellar interlopers, like the recent Oumuamua, could actually carry life and deposit it on planets, perhaps even Earth. Then Samantha debuts with a report on a new gravitational wave event, one which may be the result of a type of binary system merger we’ve been hoping for. Simon troubles us with the disturbing discovery of holes in the Milky Way that were punched by . . . something. And Amelia and Samantha talk the dazzling first-ever discovery of the so-called first-ever molecule in space.

Feature Guest: Simona Pirani

The planet Jupiter occupies a position today that is far from its home 4.5 billion years ago, a destination resulting from a primeval migration that started way out around the current location of Uranus. Like the god for which it was named, Jupiter enjoys the company of thousands of followers, the so-called trojan asteroids, which have remained by its side all these years, and they now offer a window into the murky origins of the gas giant. Today we’re joined here at The Star Spot by Simona Pirani, lead author of a new study that provides the first ever proof that Jupiter – and perhaps most planets – undertake ancient odysseys around the solar system.

We have bad news and good news. Simon puts a bit of a damper on things, as the first manned mission to Mars will have to wait longer than initially projected. Then Amelia and Samantha explain a crazy new finding: a pulsar that seems to be speeding through space! And we save the good news for last, as Tony shares new research suggesting that Earth-like planets orbiting red dwarf stars, which have been deduced as unlikely to host life, may actually be habitable after all.
