Distant Aliens & Space Dinosaurs with Lisa Kaltenegger

Has JWST found potential alien worlds? Neil deGrasse Tyson and comedian Matt Kirshen learn about exoplanet discovery on the frontier, how higher oxygen gave us dinosaurs, and what type of life could be out there with astrophysicist and astrobiologist Lisa Kaltenegger.

This artist's concept shows what the exoplanet WASP-17 b could look like. WASP-17 b, also called Ditsö̀, is a hot gas giant that orbits its star at a distance of just 0.051 AU (about 4.75 million miles, or one-eighth the distance between Mercury and the Sun), completing one full circuit in about 3.7 Earth-days.

Just Another Really Good Episode with Brian Greene

How do particles get mass? Neil deGrasse Tyson and comedian Chuck Nice discover squarks, sneutrinos, the Higgs boson, and whether dark matter has a particle with theoretical physicist Brian Greene.

An example of simulated data modeled for the CMS particle detector on the Large Hadron Collider (LHC) at CERN. Here, following a collision of two protons, a Higgs boson is produced which decays into two jets of hadrons and two electrons. The lines represent the possible paths of particles produced by the proton-proton collision in the detector while the energy these particles deposit is shown in blue. More CMS events at CMS Media

Cosmic Queries – Space Traveler’s Delight

Is there anything in the universe that is not moving? Neil deGrasse Tyson and comedian Chuck Nice answer fan questions about stillness, humans on Mars, and what songs they would add to the Voyager Golden Record.

The Whirlpool Galaxy (Spiral Galaxy M51, NGC 5194) is a classic spiral galaxy located in the Canes Venatici constellation.

Darwin’s Daring Idea with Richard Dawkins

Neil deGrasse Tyson sits down with evolutionary biologist and author of The Genetic Book of the Dead Richard Dawkins to talk about evolution, whether we were “designed,” how we are living reflections of our ancestors and much much more.

Statue of Charles Darwin in the Natural History Museum, London. The statue was created by Sir Joseph Boehm and was unveiled on 9 June 1885.

Sun Explosions with Lika Guhathakurta

Could a coronal mass ejection wipe out all electronics? Neil deGrasse Tyson and comedian Matt Kirshen learn about The Carrington Event, eclipses, and how the Parker Solar Probe doesn’t melt with heliophysicist Lika Guhathakurta.

NASA’s Solar Dynamics Observatory (SDO) captured this image of an X5.8 solar flare peaking at 9:23 p.m. EDT on May 10, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares.

Guide to Alternative Medicines with Helene Langevin

What does science say about alternative medicines and health fads? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly learn about the science behind alternative medicine with director of National Center for Complementary and Integrative Health, Helene Langevin, M.D.

Quantum Computing Corral: StarTalk Live! With Michio Kaku

Could quantum computing solve the three-body problem? Neil deGrasse Tyson and comedians Jordan Klepper and Tiffany Haddish discuss how quantum computing will change the world with theoretical physicist Michio Kaku live at the Beacon Theater.

NIST physicists used this apparatus to coax two beryllium ions (electrically charged atoms) into swapping the smallest measurable units of energy back and forth, a technique that may simplify information processing in a quantum computer. The ions are trapped about 40 micrometers apart above the square gold chip in the center. The chip is surrounded by a copper enclosure and gold wire mesh to prevent buildup of static charge.

The Magic of Chemistry with Kate the Chemist

What is chemistry? Neil deGrasse Tyson and comedian Chuck Nice take fan questions on exothermic reactions, PFAS, ice cream, sugar, fire, and more with Kate Biberdorf, aka Kate the Chemist.

On this picture you can see fluorescence of different substances under UV light. Green is a fluorescein, red is Rhodamine B, yellow is Rhodamine 6G, blue is quinine, purple is a mixture of quinine and rhodamine 6g. Solutions are about 0.001% concentration in water.

Cosmic Queries – Bits of Spacetime with Janna Levin

Is gravity fundamental to the universe? Neil deGrasse Tyson and Chuck Nice explore quantum physics, the fourth dimension, whether H2O is water, and the many-worlds interpretation with theoretical cosmologist Janna Levin, PhD.

Combined observations from Chandra (purple), the Very Large Array (yellow) along with Hubble (red, green, and blue) have provided astronomers with a detailed new look at how galaxy and black hole formation may have occurred in the early Universe. The lack of a significant bulge of stars in the center of Henize 2-10, a galaxy with similar properties to those when the Universe was very young, indicates that black hole growth may be preceding the growth of the bulge. This differs from the relatively nearby Universe where the growth of galaxy bulges and supermassive black holes appear to happen in parallel.

Low-Mass Mania with Emily Rice

Could we find life around low-mass stars? Neil deGrasse Tyson and comedian Chuck Nice find out why life might be more likely around low-mass stars, what makes brown dwarfs, galactic archeology, and more with astronomer Emily Rice.

This artist's conception illustrates the brown dwarf named 2MASSJ22282889-431026. NASA's Hubble and Spitzer space telescopes observed the object to learn more about its turbulent atmosphere. Brown dwarfs are more massive and hotter than planets but lack the mass required to become sizzling stars. Their atmospheres can be similar to the giant planet Jupiter's. Spitzer and Hubble simultaneously observed the object as it rotated every 1.4 hours. The results suggest wind-driven, planet-size clouds.

Debating Pluto’s Planethood with Alan Stern

Will Neil take back what he said about Pluto? Neil deGrasse Tyson and comedian Chuck Nice explore planets, dwarf planets, and the Kuiper belt with planetary scientist and principal investigator for the New Horizons Mission, Alan Stern.

NASA's New Horizons spacecraft captured this high-resolution enhanced color view of Pluto on July 14, 2015. The image combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). Pluto’s surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode. The image resolves details and colors on scales as small as 0.8 miles (1.3 kilometers). The viewer is encouraged to zoom in on the image on a larger screen to fully appreciate the complexity of Pluto’s surface features.
