Exoplanet Radio Ep. 29: Meet TrES-2b (aka Kepler-1b): The Planet That Reflects Almost No Light
The 365 Days of Astronomy
From Aug 29, 2023. Hosted by Tony Darnell. This planet was discovered in August 2006 by the Trans-Atlantic Exoplanet Survey. It became the very first planet observed by the Kepler Space Telescope with the designation Kepler-1b. Kepler-1b is a gas giant that is slightly larger than Jupiter and has one and a half times its mass, but orbits much closer to its star than Mercury does to our Sun. It takes only 2.5 days to complete one orbit, meaning that its year is very short. It also rotates synchronously with its star, meaning that one side always faces the star and the other...

Astronomy Cast - Ep. 733: Euclid Of Alexandria
The 365 Days of Astronomy
Streamed live on Nov 5, 2024. Last week we talked about the mission. This week we’ll talk about Euclid of Alexandria, the ancient Greek mathematician who inspired the mission. Let’s learn about his life and the ground breaking work that made so much of our modern mathematics possible. Hosted by: Fraser Cain and Dr. Pamela L. Gay. SUPPORTED BY YOU! This Episode is made possible thanks to our Patrons on Patreon. Join at the Galaxy Group level or higher to be listed in our YouTube videos.

Travelers in the Night Eps. 761 & 762: Alexandra’s Duo & Kacper’s PHA
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: - In less than two hours my Catalina Sky Survey teammate Allesandra Serrano discovered two small fast moving space rocks. Both of them passed through the Earth-Moon system unimpeded. Other space rocks are not so lucky. - An object like 2023 MN5 impacts Earth once every 90,000 years or so creating a crater 5 miles in diameter an 1800 feet deep in sedimentary rock. 50 miles from the impact of such an object...

NOIR Lab - Quasar In The Early Universe
The 365 Days of Astronomy
Observations using the Dark Energy Camera (DECam) confirm astronomers’ expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam’s exceptionally wide field of view and special filters played a crucial role in reaching this conclusion, and the observations reveal why previous studies seeking to characterize the density of early-Universe quasar neighborhoods have yielded conflicting results. In this podcast, Dr. Trysten Lambert discusses how DECam enabled astronomers to reach this conclusion. Bios: Rob Sparks is in the...

EVSN - Aquatic Planets Like Earth Could Abound in Milky Way
The 365 Days of Astronomy
From March 10, 2021. A new study examines the formation of rocky worlds from dust particles containing ice and carbon, increasing the possibility that our own Milky Way galaxy could be filled with aquatic planets similar to Earth. Plus, a simulation of the Milky Way-Andromeda collision and an overview of asteroid Apophis.

Guide To Space - How Do Ion Engines Work?
The 365 Days of Astronomy
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...

Big Impact Astronomy & Astronomy For Equity - Taisiia Karasova: Inspiring Astronomy Education in Wartime
The 365 Days of Astronomy
Hosted by Mike Simmons. Astronomy as a grounding force during war: "In times of extreme stress, focusing on studies and astronomy helps students stay grounded, offering a sense of normalcy and future hope." Taisiia Karasova, a Ukrainian student at MIT, shares her journey from founding Astro Sandbox to promoting astronomy education in Ukraine, even during wartime. She emphasizes how the Astro Sandbox initiative fosters community and academic excellence in astronomy for high school students through webinars, tournaments, and resource archives. Big Impact Astronomy: Through the...

Travelers in the Night Eps. 759 & 760: Number 7 & Discover an Asteroid
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: - Hungarian astronomer and geography teacher Krisztián Sárneczky was asteroid hunting in the constellation of Lynx with 0.6m (24 inch) telescope at the Piszkéstető station in the Mátra Mountains when an unknown object streaked through a set of his images. It is the 7th such object to be tracked in outer space and then observed to enter our atmosphere. A tiny asteroid the size of 2023 CX1 enters the...

- An object like 2023 MN5 impacts Earth once every 90,000 years or so creating a crater 5 miles in diameter an 1800 feet deep in sedimentary rock. 50 miles from the impact of such an object observers would feel the effects of a 7.1 Richter scale Earth. Rest assured that asteroid hunters will continue to track 2023 MN5 as it passes near Earth and Jupiter to make sure that its orbit does not change to make it a threat to humanity.
