    Ask A Spaceman Ep. 274: Is Dust the Best Thing in the Universe?

    All Hail Dust!

    Hosted by Dr. Paul M. Sutter.

    Why is dust so annoying? But where does it come from, and what can it do? And is dust responsible for the creation of life? I discuss these questions and more in today's Ask a Spaceman!

    Astronomy Cast Ep. 797: Summer in Space

    https://www.youtube.com/watch?v=tSIp-RwWegA

    Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest)

    Streamed live June 10, 2026.

    We're about to take a much needed 2 month hiatus. But just because we're not here doesn't mean space stops existing and doing things. Today, let's give a preview of the big events due to happen in space this summer so you can prepare yourself and make sure you don't miss a thing! From meteors to moon landings and more, join Fraser and Pamela as the look at what you can enjoy this summer, after we go to hiatus in July.

    Travelers in the Night Eps. 889 & 890: Lick Observatory & Comet 467P (Linear-Grauer)

    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 March 2026.

    Today's 2 topics:

    - 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 helped in the creation of the twin giant 10 meter telescopes that sit atop Mauna Kea in Hawaii.

    - Astronomers using the 8.1 m Gemini South Telescope in Chile were excited by the fact that 467P (LINEAR-Grauer)'s Centaur like orbit had been changed as the nucleus emitted rocket like bursts of gases as it was warmed by the Sun. Inert inactive asteroids orbit the Sun following the law of gravity whereas active asteroids can emit little rocket like bursts of gas which can change their path about the Sun in interesting ways. It is important to study objects like 467P (LINEAR-Grauer) to make sure their path about the Sun doesn't change to make them a threat to our home planet.

    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.

    Bios:

    - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona.

    - Dr. Hayley Beltz currently a Postdoctoral Associate at the University of Kansas and an incoming NHFP Sagan Fellow. Her work focuses looking at hot and ultrahot Jupiter atmospheres with three-dimensional atmospheric models and exploring how magnetic effects might change atmospheric circulation and appear observationally. She is also very passionate about teaching and mentoring students. You can find more about her, including recent papers at hayleybeltz.com

    Actual Astronomy - Observer's Calendar for June

    Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan who enjoy teaching astronomy classes and showing the public views through their telescopes. [email protected]

    This month we talk about the Moon meeting up with the planets and some interesting Lunar Features. We also talk about some of the best deep sky objects to observe at this time of year.

    I was away then sick so haven't replied to everyone's emails or I've been late. We'll read some on the next show and I'll go over what I've been up to.

    Perpetual Twilight started for us on May 29th and runs through until July 15th!

    Deep Astronomy - Vega: The Second Most Important Star in Our Sky

    https://www.youtube.com/watch?v=0NEnjp1I6GQ

    Hosted by Tony Darnell.

    From Sep 7, 2017.

    Vega, or alpha lyrae, is the brightest star in the constellation Lyra the Harp and it is the fifth brightest star overall in our night sky. It is also the second brightest star in the northern celestial hemisphere.

    Vega has also been called by astronomers the second most important star in our sky next to the Sun.

    https://www.youtube.com/watch?v=HwCk5uldz4g

    Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest)

    Streamed live on Jun 1, 2026.

    Mars is cold & dry today, but the evidence is growing that it used to be warmer & wetter. with seas & oceans that covered large parts of its surface. With the additional findings of the chemicals for life, the search for life on Mars is getting pretty interesting! New results from Perseverance and Curiosity describe a past Mars with complex chemistry and water. But did it have life?

    Travelers in the Night Eps. 887 & 888: Apophis Bound & Investigating the Mystery of How Life Formed

    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 February 2026.

    Today's 2 topics:

    - In April 2029 on one of the luckiest Friday the 13th in human history the 1,500 ft by 500 ft asteroid Apophis will pass within 23,600 miles of the Earth's surface traveling at some 4.6 mi/s. This is extremely fortunate since an Apophis impact would release the energy of scores of nuclear weapons and cause wide spread devastation. NASA's OSIRIS-APEX will become the companion of the potentially hazardous asteroid Apophis on 5 June 2029.

    - On Earth living things are everywhere from the deepest ocean depths to the highest mountain tops. On our home planet RNA (Ribonucleic Acid) is a complex essential molecule involved in the process of translating genetic information into the working components of living cells. In a recent paper in the peer reviewed scientific journal Proceedings of the National Academy of Sciences, Dr. Yuta Hirakawa and his team of two coauthors report on their experiments to produce RNA under conditions similar to those which may have occurred in the early history of Earth and Mars.
