Space Stories - Perihelion & Aphelion
The 365 Days of Astronomy
Hosted by our Director, Avivah Yamani. Earth swings closest to the Sun at perihelion and farthest at aphelion, words that apply to every planet orbiting the Sun. Learn how Kepler’s laws reveal an elliptical orbit, why Earth moves faster at perihelion, and why seasons come from Earth’s tilt, not distance.

EVSN - Mystery of Mars’ Recurring Slope Lineae Possibly Solved
The 365 Days of Astronomy
From February 8, 2021. A new theory has been proposed that could answer the question of what causes recurring landslides on Mars: small-scale ice melting just below the surface may leave the regolith vulnerable to wind. Plus, a look at some of Earth’s ancient climate changes, a gamma-ray source, puffy galaxies, and this week’s What’s Up.

Cheap Astronomy - Dear CA #128: Persistent Claims
The 365 Days of Astronomy
Still looking. Hosted by Steve Nerlich. Dear Cheap Astronomy – Is there anything new on Planet 9? Well, not really and there is some growing skepticism about whether it’s really there. Nonetheless, its original proponents, Mike Brown and Konstantin Batygin, still stick to their guns on the matter, though both agree Planet 9’s existence must be considered speculative until it is actually observed. Dear Cheap Astronomy – Is Nemesis really out there? Continuing the theme of hypothetical solar system bodies, Nemesis was proposed to be a small, dim and hence difficult to spot...

The Most Efficient Propulsion System Out There
From May 15, 2018.
People always ask me why we’re stuck with chemical rockets. Seriously, exploding a bunch of hydrogen or kerosene is the best we can do?
Good news, there are other, exotic science fiction-sounding propulsion systems out there which use electromagnetic fields to accelerate atoms, allowing their spacecraft to accelerate for months at a time.
I’m talking about ion engines, of course, and several spacecraft have already used these exotic thrusters to perform some of the most amazing missions in the exploration of the Solar System.
