  • 3567 - Ask A Spaceman Ep. 237: Could Any Supernova Harm The Earth?

    Death by supernova.

    Are we “in range” of any potential supernovae? Has the Earth ever been hit in the past? And what about gamma-ray bursts from across the galaxy, are we safe from those? I discuss these questions and more in today’s Ask a Spaceman!

  • 3566 - Astronomy Cast Ep. 735: Albert Einstein

    https://www.youtube.com/watch?v=15sOxk6cwaQ

    Streamed live on Nov 25, 2024.

    Last week we talked about the Einstein probe. So this week it is only natural that we talk about the man himself, Albert Einstein. He revolutionized the field of physics, played a vital role in the early 20th century and struggled to unite the forces of the Universe at the end of his career.

    Hosted by: Fraser Cain and Dr. Pamela L. Gay

  • 3565 - Travelers in the Night Eps. 293E & 294E: Bright and Bald & 200 Yards of Trouble

    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

    Today's 2 topics:

    - Jul 16, 2024.

    My Catalina Sky Survey teammate Carson Fuls discovered 2015 TC25 as a rapidly moving point of light in the night sky. Followup observations using data from four different telescopes has enabled a team of astronomers led by Dr. Vishnu Reddy of the University of Arizona's Lunar and Planetary Laboratory to determine that this small asteroid reflects four times more of the sunlight than do most other Earth approaching asteroids. Dr. Reddy points out that large asteroids are covered by a blanket of dust but that "Small asteroids might be bald and dust free." This team of researchers found the surface of Carson's discovery to be similar to a small meteorite which fell to Earth in France in 1836.

    - Jul 23, 2024.

    Dangerous Asteroids Are Still Out There! Recently my Catalina Sky Survey teammate Greg Leonard discovered a rapidly moving point of light in the night sky. Subsequent observations made by telescopes in Arizona, Romania, Illinois, the Czech Republic, Australia, and France revealed it to be a close approaching Potentially Hazardous Asteroid. The Minor Planet Center named it 2016 WJ1. This asteroid is about 200 yards in diameter, orbits the Sun once every 567 days, and currently can come to within about 26,000 miles of the Earth's surface. 2016 WJ1's orbit eventually will bring it near Mars, Earth, our Moon, and Venus. Any of these encounters have the potential to change it's path around the Sun.

  • 3564 - Cheap Astronomy - Dear CA Ep. 112: Getting Closer

    Next steps, if we don’t trip first.

    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.

  • 3563 - EVSN - Pluto’s Atmosphere Freezing Out as Pluto Moves Away

    From October 5, 2021.

    Scientists analyzed the results of a stellar occultation when Pluto passed in front of a distant star and found that Pluto’s atmosphere is freezing to the surface as the planet moves away from the Sun. Plus, an interview with Dr. Kat Volk regarding Transneptunian space and the possibility of Planet 9.
