Radio Stars
by Radio Stars
When we think of starlight, we typically think of the visible light stars emit against the backdrop of the night sky. But did you know that virtually all stars also emit radio waves?"Radio Stars" is a podcast series that explores how observations at radio wavelengths reveal surprising new insights into the lives and deaths of stars in our Galaxy.In this series, you will have a chance to discover more about how radio observations are revealing previously hidden secrets in the lives of some of the most familiar stars in the sky.The Radio Stars podcasts have been funded by a series of grants from the National Science Foundation to Dr. Lynn D. Matthews, Principal Research Scientist at MIT Haystack Observatory.

Radio Stars in the Era of New Observatories
In April 2024, MIT Haystack Observatory hosted an international conference titled "Radio Stars in the Era of New Observatories" that was attended by more than 60 professional astronomers and other researchers from around the world. The meeting focused on how radio wavelength observations are…

What's Up with Betelgeuse? (Part 2)
Betelgeuse is a red supergiant star visible to sky watchers in the "shoulder" of the constellation of Orion, the Hunter. In late 2019 Betelgeuse began to undergo a surprising "dimming" event before recovering its typical brightness several months later. In this two-part podcast, hear how...

Astronomy's First Radio Stars
Today we know that virtually all stars within our Galaxy emit radio waves. Using modern radio telescopes, astronomers routinely study these stellar radio waves to better understand how stars form, how they evolve, and how they die. However, for early radio astronomers, it was an enormous…

The Evolving Shapes of Giants
Even with the most powerful optical telescopes, the closest stars beyond the Sun generally appear as mere pinpoints of light, leaving us to only imagine what their light-emitting surfaces or "photospheres" might look like. However, using a technique known as radio interferometry, astronomers are...

Stellar Shape-Shifters
Planetary nebulae form when a wind from a dying star blows away its outer layers, enveloping the star in a cloud of debris that can span many light years across. Often planetary nebulae have spectacularly complex shapes, leading to whimsical nicknames such as "Eskimo" or "Cat's Eye". However, the...

Trailing Red Giants
As they near the end of their lives, stars like the Sun eventually deplete the supply of nuclear fuel in their cores. At this point, the outer layers expand and cool, until the star swells to as much as a hundred or more times its original size. Such stars are known as "red giants". Red giants…

Secrets of Cepheids
For roughly a century, Cepheid variable stars have been used as a yardstick for measuring the scale of the universe. Cepheids undergo steady pulsations, causing their brightness to undergo regular variations. Because the exact period of these brightness fluctuations is tightly linked with the...
