How to Make a Diamond the Size of Earth

David Kaplan, Associate Professor, Department of Physics, UW-Milwaukee, explains how stars die, what they leave behind and discusses the intriguing property of a recently discovered white dwarf star.

Cosmic Rays as Probes of the High-Energy Universe

Erin Boettcher, Graduate Student, Department of Astronomy, UW-Madison, discusses cosmic rays, their characteristic properties and how we can detect them from Earth. Cosmic rays can be used as probes to understand the physical conditions in other galaxies.

Finding Black Holes in the X-ray Sky

Karen Lewis, Assistant Professor, Department of Physics, College of Wooster OH, studies x-rays to find the presence of Active Galactic Nucleus (AGN)—a super-massive black hole at the center of a galaxy. Lewis explains how to pick out the AGN from the rest of the universe’s x-ray sources.

Problems with the Cosmic Fuel Supply

Aleks Diamond-Stanic, Postdoctoral Fellow, Department of Astronomy, UW-Madison, discusses the importance of cosmic fuel, or the supply of gas within the galaxies, in the creation of star formation.

The World's Largest Radio Telescope

Eric Wilcots, Professor, Department of Astronomy, UW-Madison, discusses the collaborative effort, which includes University of Wisconsin astronomers, to build the world’s largest radio telescope. The telescope will have a collecting area equal to one square kilometer, making it the most sensitive radio detector in the world.

NASA's Space Vegetables

Simon Gilroy, Professor, Department of Botany, UW-Madison, explores whether plants and microbes could provide food during a long spaceflight or in a colony on Mars. Gilroy discusses how a lack of gravity affects plants and humans.

Exploring Exploding Stars

Benedikt Riedel, Graduate Research Assistant, Department of Physics, UW-Madison, discusses researching supernovae, also known as exploding stars, at the IceCube Observatory at the South Pole.

Mapping the Structure of Spiral Galaxies

Andrew Schechtman-Rook, Graduate Student, Department of Astronomy, UW-Madison, explains advanced modeling techniques and high-resolution near-infrared imaging to study the anatomy of other galaxies and compares them to our own. Mapping this structure is essential to understanding how spiral galaxies form and evolve.

Shedding Light on Distant Galaxies

Britt Lundgren, a Postdoctoral Fellow in the Department of Astronomy, UW-Madison, explains how quasars can be used as probes in the vast intergalactic distances they cross. Lundgren explores how astronomers use this information to map the “cosmic web” of matter that shapes our visible universe.

Unlocking the Secrets of Why Black Holes Shine

Cami Collins, Research Assistant, Department of Physics, UW-Madison, asks how stars and planets form and why some black holes are the brightest objects in the universe. Collins discusses the underlying physical mechanism which could reveal the answers.
