Things You Thought You Knew – Magnetic Cores & Flipping Poles

Is your compass actually wrong? Neil deGrasse Tyson and comedian Chuck Nice explore magnetic fields, why clocks go clockwise, and how phone numbers got their area codes.

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. Here we have created a time-lapse version of these models over four days (2-3 each day) to give you a peek at how these change over time. The spiraling arcs of magnetic field lines emerge from active regions and connect back to areas with the opposite polarity. The field lines are more concentrated where regions are more magnetically intense. And of course, they rotate with the rotation of the Sun.

Fact and Fiction of Health and Wellness with Dr. Nick Tiller

What are the top myths in the health and fitness industry? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly explore pseudoscience, “quick fix” fads like Ozempic, and how to navigate wellness with exercise scientist, Dr. Nick Tiller.

The supplement business is a multi-billion dollar industry that is not currently regulated like conventional food and drug products by the Food and Drug Administration. The use of supplements is designed to add further nutritional value to the diet, not act as a meal replacement. (U.S. Air Force photo illustration/Airman 1st Class Daniel Brosam)

Black Hole Bonanza: StarTalk Live! With Janna Levin and Jenny Greene

How do supermassive black holes form? Neil deGrasse Tyson and comedian Chuck Nice come to you live to learn about the history of black holes, what’s inside them, and new discoveries with cosmologist Janna Levin and astrophysicist Jenny Greene.

This image of Centaurus A shows a spectacular new view of a supermassive black hole's power. Jets and lobes powered by the central black hole in this nearby galaxy are shown by submillimeter data (colored orange) from the Atacama Pathfinder Experiment (APEX) telescope in Chile and X-ray data (colored blue) from the Chandra X-ray Observatory. Visible light data from the Wide Field Imager on the Max-Planck/ESO 2.2 m telescope, also located in Chile, shows the dust lane in the galaxy and background stars. The X-ray jet in the upper left extends for about 13,000 light years away from the black hole. The APEX data shows that material in the jet is travelling at about half the speed of light.

Cosmic Queries – The Atlas of Peculiar Galaxies with Charles Liu

How can we use AI to explore the universe? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly answer grab-bag questions about simulations, black holes, warp drive and more with astrophysicist and “Geek-in Chief” Charles Liu.

UGC 8335 is a strongly interacting pair of spiral galaxies resembling two ice skaters. The interaction has united the galaxies via a bridge of material and has yanked two strongly curved tails of gas and stars from the outer parts of their bodies . Both galaxies show dust lanes in their centers. UGC 8335 is located in the constellation of Ursa Major, the Great Bear, about 400 million light-years from Earth. It is the 238th galaxy in Arp's Atlas of Peculiar Galaxies.

Cosmic Queries – Cool Worlds with David Kipping

What is the weirdest planet ever discovered? Neil deGrasse Tyson and comedian Chuck Nice discover bizarre exoplanets like Erebus, the impacts of living on a habitable moon, hot Jupiters, and more with astronomy professor David Kipping.

The distant exoplanet TrES-2b, shown here in an artist's conception, is darker than the blackest coal. This Jupiter-sized world reflects less than one percent of the light that falls on it, making it blacker than any planet or moon in our solar system. Astronomers aren't sure what vapours in the planet's superheated atmosphere cloak it so effectively.
