Today we’re talking with Voyager Deputy Project Scientist Dr. Jamie Rankin and learning about all things interstellar, from not only the twin Voyagers (humanity’s only interstellar spacecraft) but also from spacecraft operating within our star system.
We’re celebrating the 35th anniversary of the first and only Portrait of the Solar System, a series of images taken by Voyager 1 on 14 Feb 1990. Dr. Candice Hansen-Koharcheck tells the story behind this portrait. She and Dr. Linda Spilker also talk about their career-long friendship.
Several of the planets and moons in the Solar System are in orbital resonance, orbiting in a geometric lockstep. And not just the Solar System, astronomers have found the same resonances in other star systems.
The Solar System is more volcanically active than we thought. Today, we’ll explore volcanism on other worlds.
We’ve sent robots to other worlds but the amount of science we can deploy can’t compare with the vast science labs we have on Earth. That’s why more and more missions are for a sample return.
Last week we talk about the spacecraft which are helping to study Earth from above. Now @AstronomyCast will talk about missions close to home that helping us understand our place in the cosmos.
What’s all the fuss about Venus our Mars-bound astronauts survive years of exposure to space radiation?
Well yes, they can potentially, but solutions are yet to be
Could we nudge the orbit of the Earth to avoid the death of the Sun? Could it get kicked out of the solar system altogether? What are rogue exoplanets?
The @AstronomyCast reach 666 episodes. To celebrate, here’s an episode about things in the Universe that have been named after mythological people and places in the underworld!
Using a first-principles approach, researchers have discovered that the differences in the rotational rate of the solar system are due to the inward and outward flow of cations and electrons.
