Starship Asterisk*

At first I ho-hummed this APOD, because I didn't find it beautiful or immediately interesting. https://apod.nasa.gov/apod/image/2404/Pa30V_NASA_960.jpg ... Wikipedia wrote about Pa 30, the nebula seen in today's APOD: Pa 30 was discovered in 2013 by American amateur astronomer Dana Patchick while s...

How far out do the petals of the corona extend? They seem huge. As the final countdown to the April 8 total solar eclipse approaches, use the Helioviewer Eclipse Watch tool to observe eclipse-like images that are captured over 100 times each day by the LASCO C2 coronagraph on the Solar and Heliosph...

One thing that Hubble has revealed, that is not visible in the APOD, is that the black hole of NGC 4438 is blowing bubbles: https://cdn.esahubble.org/archives/images/screen/opo0021a.jpg https://thumbs.dreamstime.com/z/little-boy-chewing-bubble-gum-vector-illustration-happy-child-popping-bubbles-223...

https://apod.nasa.gov/apod/image/2403/Seagull_Lacroce_1080.jpg That's an interesting and very red portrait of the Seagull Nebula. I can't complain. The Seagull Nebula is very red, since it is heavily dominated by 656 nm Hydrogen Alpha, which is of course this color, ███ . Only one other color is im...

ThanX Ann There you made some good points there. It will be exciting to see what future research on this object will reveal as the fog surrounding the central object slowly clears. I think the study above is just a first step and will not be the only one. I like SN 1987A also as WEBBLE ;-) https://...

Thanks for your fantastic images, Jac! I absolutely agree that Sanduleak −69° 202, the supernova progenitor, must have undergone cyclical outbursts. The reason why the outer outlines "from the star to the supernova remnant" are completely unchanged can only mean, the way I understand it, ...

I'd just say that understanding objectively derived probabilities is an important tool for guiding scientific investigation. If you're going to conduct an investigation, it makes sense to start with the most probable hypotheses. Agreed. Thanks. The pair that make up Arp 256 are two of my favorite g...
