- In 1892 the world's largest telescope, the Lick Observatory's 36 inch refracting telescope made the news when E.E. Barnard discovered, Amalthea, the 5th moon of Jupiter. In 2025 this historic telescope made the news again when on Christmas morning winds of 114 mph blew off a 3 ton piece of the shutter on its dome. The adaptive optics research pioneered at Lick Observatory...
NOIRLab - Strong Hints of Magnetic Fields On Exoplanets
Using the Gemini North telescope in Hawai'i and the European Southern Observatory's Very Large Telescope, a team of astronomers measured wind speeds on seven very hot, Jupiter-like exoplanets. The observations revealed that the winds on these planets are most likely governed by magnetic fields, providing the first robust measurement of magnetic activity on planets outside the Solar System. In this podcast, Dr. Hayley Beltz describes how these magnetic fields were discovered from observations using data from the Gemini North telescope in Hawai'i and the European Southern Observatory's Very Large Telescope.

Guide To Space - Lunar Rovers, From Apollo to Artemis
https://www.youtube.com/watch?v=larzCw9Vn-w
From Jul 21, 2020.
When the Apollo astronauts first landed on the Moon, they couldn't go far on foot. That's why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science.
Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it's considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon.

UNAWE Space Scoop - Story Of the Sun's 'Road Trip' Through the Milky Way With Friends
https://spacescoop.org/en/scoops/2605/story-of-suns-road-trip-through-the-milky-way-with-friends/
Did you know that our Sun and its many, uh, childhood friends were all born at a place much closer to the center of our Galaxy? Over the years, our Sun and its friends have been on sort of a speedy galactic tour traveling a distance of almost 10,000 light-years from the center of the Milky Way. But traveling much farther than that on a long curved trajectory! Astronomers call this the 'mass migration' of stars. Kind of like a flock of migrating birds.
How and when did th...

Exoplanet Radio - The First Exoplanet Of JWST
Hosted by Tony Darnell.
From July 17, 2023.
The James Webb Space Telescope Has confirmed its first exoplanet, LHS 475 b, in the southern constellation Octans, using the transit technique. The TESS satellite detected the possible presence of it and JWST's NIRSpec instrument has confirmed the observation. The planet is 99% the diameter of Earth & 91.4% of Earth's mass. So your first hope is that it's a second Earth. The orbital period is only 2 days, though, so it's assuredly tidally locked & very hot. It's unlikely to have an atmosphere either, so you can forget about finding life there.
Astronomy Cast Ep.139: Energy Levels & Spectra
http://www.astronomycast.com/archive/
From May 25, 2009.
Last week (May 18, 2009) we took a peek into the tiny world of quantum mechanics, and its unintuitive, but very accurate mathematical predictions. And although we all appreciate the physics lesson, you're probably wondering what this all has to do with astronomy. Well, today we bring it all home and explain how quantum mechanics has given astronomers one of the most powerful tools they have to study the nature of the cosmos.

Guide To Space - Finally! An Explanation for One of the Most Powerful Supernovae Ever Seen
https://www.youtube.com/watch?v=OEZu3pXAFWY
Hosted by Fraser Cain.
From Jan 31, 2020.
In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual.
This clearly wasn't a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer.
