Starship Asterisk*

It would be interesting to have a video of this...because the previous wave is pulled out, but not the interval between the waves... though Daphnis should be pulling the whole way.... :---[===] * Take a look at the "making waves" link. It seems like an animation like you are asking about....

Microsoft did an update recently to the Windows OS. Things misbehaved for me until I realized the need to Restart my computer allowing the updates to install. If your OS is Windows and you do not normally turn off your computer, you might be experiencing problems due to the updates not having instal...

The refraction in atmospheric layers, reflected in the waters is forcing me to look further into the definition and meaning of the two words. The Asterisk uses them extensively but until now they were just technical terms from scholars who did know what they were talking about. Light being refracted...

2)These pillars are indeed being pushed away rather than "evaporating" as we normally think of it...but they are being pushed away by radiation pressure rather than by stellar winds. To some degree the dust really is evaporating (although "sublimating" might be a more accurate d...

It was beautiful then, it is beautiful now. This is one of the first pictures I shared with friends to show what APOD is. I also love the angel. But the views are really whatever we see. Thank you APOD for finding me and allowing me to share you. Thank you to the core persons for putting up with me ...

I think the date on this moons picture should be the 23rd, and the discuss link should go to the picture for the 23rd.

Catching the Red Eye back to Earth from the Asterisk.

Click on the "featured here" link.

Makes one wonder; how much energy could be saved and how much pollution diminished were we to turn out the lights. The lights not being used by anybody and just lighting up the planet for no reason. People want them on for security? Activate those lights with motion detectors. If nothing is using th...

From 1:31 to 1:38 it looked like the sun was watching Mercury through a set of eyes. Gotta cut down on my coffee intake...

I've never seen a Mercury transit. The past three were obscured by clouds in my area. Despite a lot a of cloudy/rainy weather recently, the forecast for tomorrow looks good through the early afternoon, so keeping my fingers crossed, I'll have a chance to see much of it. In my area at 40°N-75°W, sun...

The Eastern Seaboard link brings up the question of terminology. Terms for where the ocean meets the land on the Eastern and Western sides of the U.S. of A. Eastern Seaboard as compared to the West Coast. My understanding of the non-issue is the coasts were named by the European nations which settle...

If it helps, click the E of the five links in the word Earth for a roll over

There are some guys that can hit a ball a fare distance. I look at today's picture and can't help but think on the other side of this small world is the word Titleist. It is almost round enough and the dimples seem about right.

The expression "Gyr" means "billion years. It does (although "billion" is ambiguous). However, if you're doing your own writing, "Ga" is the preferred unit for 10 9 years. Thank you Chris, for reminding us that from 'ten to the ninth,' onward, this world does not ...

I, also, want to thank Art.

The 95% vs 5% cleared up discrepancies and misunderstanding I had regarding postings I had read.

Wow! Beautiful picture. F. H. Hemmerich has done a wonderful job capturing this image IMHO. Today's APOD goes into my saved photos collection. Ann, thank you for the link showing the previous wide tailed image. Both wonderful pictures and so different in colors. Is the difference in the colors due t...

"by grammar granny » Sat Nov 28, 2015 5:16 am Please. It's its, unless you mean it is, in which case it's it's. Check any dictionary. The possessive does not have an apostrophe. You write his rather than hi's, don't you?" GG, I would get on the grammar bandwagon with you if this were not t...

AE Aurigae. That left me wondering if it was named for somebody. (IE WC Fields). The two-letter name implies variability, and indeed the star does vary between magnitudes 5.4 and 6.1.

The picture in my mind is of a field of snow. Along comes a bunch of people. The loose snow gets compacted into snowman bodies and snowballs. My view is fun but unrealistic as it is not gravity pulling the balls together, but compression pushing them to form. Be prepared for snowball fights and a sn...

I agree, not star trails but the water being ever so slightly disturbed by a very low frequency wave.[/quote] http://core0.staticworld.net/images/article/2014/04/smoothly-water-waves-ripple-water-concentric-circle-wave-splash-000001280919-100264173-primary.idge.jpg The bright streaks are probably Je...

Arrrrrrrrr matey, The picture be wonderful. I would like to say many a similar scene has exposed itself to my eyes as I traveled the Pacific, Atlantic, Arctic and Med seas. Yes, I would like to say that. But I was in a submarine and didn't get to see the beautiful skies reflected in the ponds I was ...

Sure seemed like the woodwork was leaking trolls filled with wrath because the APOD was not exactly to there liking. I loved it. Some points were made re why they thought the picture was incorrect and I thank them for pointing out what was inaccurate. But the picture was chosen for both the data pre...

My Modus Operandi is similar to what Chris wrote above. In one tab I open the APOD. Then Right Click the mouse on the picture and open that in a second tab. Third, I Right Click on the "Discuss" link and open that in a third tab. Pro tip: If you press your scroll wheel / middle mouse butt...

Beautiful image! One bit of feedback for APOD: it would be nice (not just for today's image, but more generally) if clicking the image brought one to a high-res version of the image. I like to download and collect APOD images, for use as desktop images, but I often have to track down the high-res v...
