    [Interview] Observing Black Holes With Just One Telescope

    [Interview] Observing Black Holes With Just One Telescope

    Previously the only way to image black holes was with the Event Horizon Telescope, a combination of many radio telescopes across the globe. It is complicated and time-consuming. But with Vera Rubin going online soon, there might be a simpler way to observe black holes with a single telescope using a really clever method.

    [Space Bites] Eyeball Exoplanet // Plant to Terraform Mars // Smelly Find by JWST

    A strange eye ball world seen by Webb, did ancient astronomers see a kilonova in the sky, extreme moss that could handle Mars, and Ariane 6 flies successfully to space (mostly).

    [Q&A] Intergalactic Stars, Sun Switching Poles, A Second Sun

    Can stars be born without a parent galaxy? Can quasars destroy life in an entire galaxy? Is there another planet in our Solar System after all? Did the Sun have a sibling star at some point? Answering all these questions and more in this week's Q&A show.

    [Interview] The Quest for Earth 2.0: Discovering Exoplanets by Suppressing Starlight

    [Interview] The Quest for Earth 2.0: Discovering Exoplanets by Suppressing Starlight

    Seeing an Earth-like planet around a Sun-like star isn't possible with current telescopes. The difference in brightness is just too big. But future space telescopes will have multiple tricks up their sleeve specifically for that. Which ones? Finding out in this interview.

Informative

One of my favourite astronomy podcasts. I enjoy hearing updates about missions, and I enjoy the more in-depth interviews. The other day, this podcast came to mind when we were talking about JWST and I have no hesitation in recommending it!

Best astronomy and space news podcast

Fraser’s channel is simply the best, most well-informed astronomy and space news podcast on this small blue planet. Everything else is a brown dwarf by comparison. David

Catch up on the Universe!

Universe Today- the title says it all. To find out the latest, most significant news in Space and Astronomy this is the podcast. And it doesn’t just skim over the top, it delves into explanations of the science.
As well it has some excellent guests for in-depth interviews.
Today Fraser told us about those rogue Jupiter planets in the Orion Nebula. I had heard about them in the mainstream media, but Fraser had the good insight on what it means for astronomy on a broader scale.
