The Cosmic Recycling Plant: The Life Cycle of Low Mass Stars from Main Sequence to Red Giant to Planetary Nebula and White Dwarf!

 

I've spent a lot of time lately discussing super massive stars, their explosive ending as supernova and shared a program for seeing their remenants, ie supernovae remnants.  

Now we'll take a look at the opposite side of the coin. Here we discuss main sequence stars that are from 0.4 to 8 solar masses (stars similar to our own Sun) and discuss their lifecyle and how they end up as planetary nebula with white dwarf stars. 

The video is long, and I share my notes that I have created on this from my Astronomy Class way back in college many, many years ago.  I've tried to update it.  Anyway, this is to prepare to share a Planetary Nebula Observing/Imaging Program.

Weather Apps and Sites I use for Astronomical Imaging and Observing

 

This is a recap of the sites I use to make a weather forecast to determine if I want to drive out to a dark site for 1 1/2 to 2 hours and observe.  I've shared parts of this before, and I've added a few items also now.  

For the complete set of videos and the article with all the links to the sites I use, head over to Eadsy Astronomy at the this LINK. You can do the same as I do by using these sites or do a search for similar sites in your area. I do strongly believe that if you really want to ultiilze a dark site, it helps to become an amateur weather forecaster for your region and locations you observe.

Over 70% of massive stars are born in binary systems, but after mass transfers, mergers, or supernova explosions separate them, surviving stars often appear solitary. Until now, astronomers struggled to trace whether a single star had a violent binary past.

A new study published in Nature Astronomy by researchers at the University of Bonn and the Max Planck Institute for Astrophysics introduces a novel, model-independent method to uncover these hidden histories. Come learn more in the video and over at Eadsy Astronomy below!

Eadsy Astronomy Newsletter: August 30th to September 5th (really the 12th) 2026

 

Here is the Eadsy Astronomy Newsletter for next week, August 30th to September 5th. Really this needs to work through September 12th as the week of the September 6th I will be in Yellowstone for a family vacation.  

Here are the segements if you just choose to watch those portions. 

00:00 to 4:03 is Intro; Lunar Phases by Day and Craters and Features to Observe 

4:04 to 7:03 Planetary Items and Double Stars 

7:04 to 9:10 Comets 

9:10 to 10:07 Deep Sky Targets/Objects

New Classical Nova in the Constellation of Sagitta: V488 Sagittea

 

Nova Sagittae 2026 or V488 Sagittae (N Sge 2026 / PNV J19450648+1822422) erupted on August 25, 2026, making it one of the most accessible Milky Way transients of the year due to its high altitude in the summer sky.

What it is: A classical nova caused by a thermonuclear explosion on the surface of a white dwarf that is actively pulling in material from a companion star in a close binary system.

Prior to the outburst, the progenitor star was a faint speck down around magnitude 19 to 21, but it rapidly flared up by tens of thousands of times in brightness. Because it is sitting right around 7th magnitude, it is easily reachable with standard binoculars, even from urban or suburban backyards, though it remains just below the threshold of naked-eye visibility

My Experience with the Lunar Eclipse on August 27th, 2026

 

Life is sometimes definetly like a box of chocolates and sometimes you just have to roll the dice to see what comes up.  Last night was one of those. I wanted to experience this partial Lunar Eclipse and the forecast went from bad to horrible. However, I foudn a window at a place called Five Mile Pass, about 35 minutes from my home so I went there. 

I posted the video shorts here on this channel but over at Eadsy Astronomy and I shared the images I took, the videos are all in one place and it covers what I experienced. Was it a perfect session? Nope, I missed the main event but I did maximize my opporutnity and sometimes in life, that is what we have to do.
