If light always travels at the speed of light, how does it slow down when passing through air or water? Does it matter is light is made of particles or waves? What’s the difference between phase velocity and group velocity, and how does that all play into this?
One of JWST’s top jobs is to peer deeper into the Universe than ever before, watching as the first galaxies came together. What’s going on and what does it mean for cosmology?
Venus shines bright at sunset all month, with Mars nearby, while Saturn, Jupiter, and even Mercury shine in the mornings, and the Beehive Cluster gets two wandering guests, all in the solstice month of June.
In science fiction, wormholes are a method often used to travel great distances across space. Are these magic bridges really possible?
Today Actual Astronomy talk about watching Mars pass through M44, the Beehive Cluster as well as other sights to see in the June Night Sky. We go over some of the pairings of the Moon and Jupiter, Saturn, and Venus during its best appearance for the year.
Join us as we take a deep dive into the history of atmospheric methane on Mars and Titan, how that methane could be a sign of life, and what methane means for future missions and science. Plus, a planetary nebula, a supernova, ancient helium, and a couple of rockets.
Astronomers describe ‘cosmic noon’ as a dramatic period in the history of our Universe when it was buzzing with galaxy mergers and furious star formation. And here’s the evidence of the early merger.
After the cosmic microwave background radiation was released, the Universe returned to darkness, cloaked in this clouds of primordial hydrogen and helium. Gravity pulled these vast clouds into the first stars, and then the first galaxies. This is Cosmic Dawn, and JWST will help us probe this mysterious time in the Universe.
