We’ve plundered Earth, what’s next?

Dear Cheap Astronomy – If we did colonize the Solar System, what would we do with the different planets?

It remains to be seen if we will spread out across the solar system. While we starting to feel more confident about avoiding a mass extinction asteroid strike, a super-volcano eruption could just as easily end civilization as we know it. There’s also the more mundane scenario of where our population keeps growing, we run low on resources and then fight a bunch of wars over what’s left, pretty-much trashing what’s left of the ecosystem in the process.

Dear Cheap Astronomy – If we colonized the Solar System, Part 2

In part 2, we are looking into the far future which has access to speculative technologies, which may or may not come to pass. Indeed, as we stated in Pt. 1 we may never get beyond leaving a few footprints on our local satellite before civilization as we know it collapses. But if we assume the rise of technology can be kept on its current trajectory indefinitely, then sure, all sorts of things could become possible.

From December 11, 2024.

From baby planets to ancient black holes, let's look at the week's space news, including the discovery of a planet around a still-forming star, our Sun's massive outbursts as measured by tree rings, a new catalog of white dwarfs in binary systems, and a deep dive into the possibility that black holes create dark energy. As always, we'll also bring you tales from the launch pad.

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. [email protected]

The Actual Astronomy Podcast Episode 464 presents Observing Lists and Eyepiece Cleaning. In this episode we talk about a few observing lists Chris is working on for the RASC Observer's Handbook and Calendar plus some Wide Field Wonders.  Shane details his cleaning process for eyepieces.

My little counterweight arrived!

Bought a semi-truck snow brush to clear snow from the rails

Sadly where the roll off rails enter the observatory freezing rain and snow accumulate behind the wheels, builder can fix it but we need warmer weather.

A lot of folks wrote about why the 7-inch wasn’t up in the observatory…this is why since it eats up so much room it is difficult to work in there.

A couple notes on the RASC publications I’m involved with. Due to our postal strike here in Canada we have to delay giving out a copy of my RASC Observer’s Calendar which I edit each year. The good news if you are in the states there is a bundle sale for the Observer’s Calendar and Observer’s Handbook, $44 and with the exchange favouring our American friends it is nearly a buy one get one free situation.

2024 was a strange year! I’ll let your imagination take flight and consider how 2024 was weird for you. But, for space and astronomy we had some interesting, revolutionary, unsettling and downright weird stories pop up. Today let’s talk about them.

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:

- The more we learn about 322P/SOHO the stranger it becomes.

- In 2023 T. Maroti of the Capricornus Observatory, Csokako, Hungary discovered two Earth approaching asteroids which were passing through the night sky unnoticed by other observers. His equipment is an 11 inch telescope, electronic camera, and computer.

Gravity has shaped our cosmos. Its attractive influence turned tiny variations in the amount of matter present in the early Universe into the sprawling strands of galaxies we see today. A new study using the first year of data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of how gravity behaves at very large scales. In this podcast, Dr. Pauline Zarrout discusses these results and the future of DESI research.

Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

From 2015 to 2018, Pauline did her PhD at CEA-Saclay on the clustering analysis of eBOSS quasars. She is a laureate of the 2018 L'Oréal-Unesco fellowship For Women in Science. Then, she continued as a postdoctoral researcher in DESI at the ICC at Durham University. Since October 2020, she is a CNRS researcher in cosmology at LPNHE.

From Jun 22, 2021.

Minor planet 2014 UN271, discovered in data collected by the Dark Energy Survey, is set to make a close pass to Saturn’s orbit at the end of the decade, giving astronomers a chance to observe a rare trans-Neptunian object from up close...ish. Plus, Venus, Jupiter, the Milky Way, and an invisible galactic structure discovered quite by accident.

(From Wikipedia)

Andrew L. Chaikin (born June 24, 1956) is an American author, speaker and science journalist. He lives in Vermont. He is the author of A Man on the Moon, a detailed description of the Apollo missions to the Moon. This book formed the basis for From the Earth to the Moon, a 12-part HBO miniseries.

From 1999 to 2001, Chaikin served as executive editor for space and science at Space.com. From 2008 to 2011, he was a faculty member for Montana State University in Bozeman, Montana. In 2013, he wrote and performed the narration on a NASA video re-creating the taking of the famous Earthrise photo during the Apollo 8 mission.

His book A Man on the Moon: One Giant Leap states that he grew up in Great Neck, New York, and, while studying geology at Brown University, worked at the NASA/Caltech Jet Propulsion Laboratory on the Viking program.
