Exoplanet Radio - Ep. 20: TRAPPIST-1d: A World on the Edge of Life
The 365 Days of Astronomy
From Aug 15, 2023. Tucked inside a quiet solar system, in the area of sky outlined by the constellation Aquarius, orbits a planet named TRAPPIST-1d, the third of seven planets in a system positioned 41 light years from our vantage point. TRAPPIST-1d is a rocky, Earth-like planet, meaning that it is roughly the same size and mass as our home.

EVSN - Climate in Crisis & Stars in Formation
The 365 Days of Astronomy
From June 5, 2024. In this episode, we bring you stories on how JWST - Not LIGO and Virgo - spotted the most distant Black Hole merger to date, why the search for life on other worlds gets more challenging the more we look, and we take a deep dive into the things we’re doing that cause and relieve climate change.

Cheap Astronomy - Dear CA #104: Moving Out
The 365 Days of Astronomy
Checking out the neighbors. Dear Cheap Astronomy – Is solar or nuclear better for a future Mars base? A common theme on Cheap Astronomy, with regards to space exploration is that just because we can do it, doesn’t mean we will do it, since any billion dollar investment is going to require some kind of return on investment, whether that be an actual monetary return or political capital, or whatever. And even then, if there’s a major risk of people dying and/or the mission failing, it probably won’t get off the ground in the first place. Dear Cheap Astronomy – Can we look...

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: - More than 240 Lunar meteorites have been found in the Dhofar region of Oman, on the LaPaz Icefield of Antartica, and other locations on the Earth's surface. These space traveling rocks were blasted from the Moon's surface by the impact of asteroids and comets which accelerated them to speeds greater than the lunar escape velocity of 1.5 miles per second.

Today's 2 topics:
- More than 240 Lunar meteorites have been found in the Dhofar region of Oman, on the LaPaz Icefield of Antartica, and other locations on the Earth's surface. These space traveling rocks were blasted from the Moon's surface by the impact of asteroids and comets which accelerated them to speeds greater than the lunar escape velocity of 1.5 miles per second. Subsequently these interplanetary travelers in the night orbited the Sun for an extended period of time before entering our atmosphere and falling to Earth. We know these meteorites are from the Moon because they contain mixtures of atoms which are found on the Moon but not in Earthly rocks.
- Recently in the space of 28 hours my Catalina Sky Survey teammates Rose Matheny and Carson Fuls discovered two Potentially Hazardous Asteroids to add to the list of the more than 1700 which asteroid hunters have discovered. Fortunately, none of the Potentially Hazardous Asteroids are currently on a collision course with planet Earth.
