    Travelers in the Night Eps. 363E & 364E: House Sized Space Rocks & Jupiter

    Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From November 2025. Today's 2 topics: - Throughout history small close approaching space rocks have been a part of our environment. Now, thanks to improved telescopes and cameras, asteroid hunters are routinely discovering these small asteroids as they pass closer than the Moon is to us. Since these tiny asteroids are only bright enough to detect for a few days out of their long, many month duration paths about the Sun, astronomers have had difficulty in determining how many of these small space rocks may exist in near Earth space. This effort received more emphasis when a house sized space rock exploded over Chelyabinsk, Russia in 2013 releasing about 10 times the energy of the Hiroshima atomic bomb.   - Jupiter has been observed throughout human history and is so bright that you can even spot it under the artificial light dome of one of our cities. Even so it is less than 40 years ago that we were first able to view Jupiter in detail as the Voyagers streaked by it. Jupiter contains more than twice the mass of all of the other planets, dwarf planets, asteroids, and comets in our solar system combined. Eons ago, our solar systems very own giant planet, Jupiter, appears to have cleared out the inner solar system leaving enough rocky debris to form Mercury, Venus, Earth, and Mars.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

    UNAWE Space Scoop - A Blazing Hot World With A Buzzing Secret

    https://spacescoop.org/en/scoops/2608/a-blazing-hot-world-with-a-buzzing-secret/ Hosted by our editor, Richard Drumm. Far, far away from Earth, over 300 light-years away, is an incredible exoplanet called WASP-189b, in the constellation Libra, the scales. It lies a bit to the NW of Beta Librae, or Zubeneschamali, and almost exactly due north of the Libra star with my favorite star name: Zubenelgenubi! WASP-189 is the star & 189b is the planet.   It has about twice Jupiter's mass and about 1 1/2 times its diameter. It orbits its star in 2 days & 17 hours, so it's really close in! But this isn't just any old planet. 189b is a giant, blazing-hot world with a secret that has astronomers buzzing with excitement!  Ah, that's where the buzzing in the title comes from!   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

    Guide To Space - Betelgeuse Is Still Dimming! And We Have the Pictures to Prove It

    https://www.youtube.com/watch?v=gC4LEozmqXE From Feb 16, 2020. Hosted by Fraser Cain. Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months. It's a variable star, and it's known to get dimmer and brighter, but the big surprise is that it's still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star.   The world's biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the star's surface and surrounding area showing how it's dramatically changed over the course of 2019.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
