Travelers in the Night Eps. 299 & 300: Caves of Mars & Lost and Found
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: - Aug 27, 2024. Presently the surface of Mars is very dry and any liquid water that reaches it quickly boils away since the martian atmospheric pressure is what you could experience in your space suit 30 to 50 miles above the Earth's surface. However, since the martian gravity is about 1/3 that of the Earth, its crust is less dense and more porous than what we find on our home planet. - Sep 3, 2024....

EVSN - Cool Worlds, Exploding Stars, & An Asteroid That Missed Earth
The 365 Days of Astronomy
From August 20, 2020. Join us today as we look at how citizen science helped discover 100 cool worlds nearby. Then we examine evidence that exploding stars may have contributed to a mass extinction on Earth. Speaking of mass extinctions, an asteroid narrowly missed our planet last weekend. Because 2020.

Big Impact Astronomy - Cosmic Webs and Hands-On Learning with Mark Neyrick
The 365 Days of Astronomy
Hosted by Mike Simmons. - Mark Neyrick, cosmologist and research scientist at Blue Marble Space Institute, explains the cosmic web of galaxies and matter, and how this large-scale structure mirrors branching structures in nature, like trees and rivers. He discusses the artistic and educational method of using origami and tactile models to teach complex cosmological concepts, making science more accessible and memorable. - Origami models make cosmic webs tangible! By folding paper and fabric, Mark illustrates how dark matter forms cosmic filaments, offering a hands-on approach to...

The 365 Days of Astronomy
Streamed live on Jan 27, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay Gravity Waves ... not gravitational waves ... move atmospheres and make pretty clouds. Have you ever looked up into the sky and seen bizarre cloud formations that look like waves on the ocean? These are gravity waves. Not to be confused with gravitational waves, and they’re caused by a balance of buoyancy and gravity. And of course these have been seen across the solar system.

Today's 2 topics: - Richard Kowalski discovered 2016 WM48, a Centaur. Centaurs are named after the mythical beasts which were half human and half horse perhaps because they have characteristics of both asteroids and comets. 2016 WM48, is about a mile in diameter. We don't know if it has rings, tiny moons, or a gas cloud surrounding it as some other Centaurs do. 2016 WM48 must have had a catastrophic...

Hosted by Steve Nerlich.
Dear Cheap Astronomy – How will we find the first evidence of extra-terrestrial life?
Well of course, we don’t know – the question is more invitation to review the various options and rank the relative likelihood of those options based on the information we have to hand. So - it’s possible that we’ll first find evidence of intelligent life in the form of an electromagnetic signal of technological origin coming from another star system.
Dear Cheap Astronomy – Are we safe from asteroid impacts now?
No, but we are safer. The recent DART mission showed that you can divert the trajectory of an asteroid by impacting it with a fast moving spacecraft. The 2022 DART mission demonstrated that the DART spacecraft’s kamikaze crash moved the asteroid Dimorphous by some tens of metres. Tens of metres won’t save Earth from a collision with an object that’s already closing in – but from sufficient distance such fractional shift could very well modify its trajectory so that it misses.
