Starship Asterisk*

Thanks Chris and neufer for your help.

Having read more of the many links I've now found this "Moving back at supersonic speeds that sent a sonic boom across Florida’s Space Coast, the first stage engines ignited to slow the booster down as it neared Landing Complex-1".

I'm not very good at understanding the physics of launchings/landings so please don't accuse me of being stupid as I don't understand why the engines are apparently being fired for a landing, as surely that would result in lifting! I'm sure it's not but it does look as if the video could be being sh...

In the explanation it states the image was "taken in 1996" but in the information in the related Hubble NewsCenter release (including its Fast Facts) it states the exposure was in September 1995 (the image was however released on June 10 1996).

What time of day and year was this taken? I wonder how often (during a year) the milky way appears to come straight up from the horizion (facing south?) as it does in this picture. Hi cindy4444. In the EXIF information that I was able to obtain it stated "Exposure: 77 sec, f/4, ISO 6400. Date:...

The image of the Earth brought up through the "blue marble" link is awesome (just like similar images). I doubt I will ever tire of seeing such wonderful images.

It's an excellent scene. Though out of view on the left I suspect that there may have been just as much activity there. It would thus have been an even more wonderful sight. On trying some online translations of the Chinese text with the image I was amused by one that translated 3200 Phaethon as 320...

It took some finding but I've eventually managed to find that GLASS stands for 'Grism Lens-Amplified Survey from Space'. There were so very many links in this APOD that surely one more could have been done!

Thanks for your help and suggestion Chris.

Something that I've noticed for some time now is the large number of image and/or social network accounts that some people have (not just APOD contributors) that I wonder how they ever get time to really concentrate on what they are providing!

When I click on the 'José Jiménez Priego' link in the credit I get a message in the Facebook website that states "The link you followed may have expired, or the Page may only be visible to an audience that you aren't in.". If the link has expired it seems far too early. If I need to be a m...

This nice image was used as the Earth Science Picture of the Day (ESPOD) on December 6 2015. For anyone like me that likes to know when a photo used an APOD was taken the information with the ESPOD states it was taken on November 21, 2015. A quibble of mine is that the photographers name/coloured ic...

In the information brought up through the 'Oort cloud' link it states "The Oort Cloud is believed to be a thick bubble of icy debris that surrounds our solar system. This distant cloud may extend a third of the way from our sun to the next start -- between 5,000 and 100,000 astronomical units. ...

It's a fascinating image, in which there also seems to be a lot of galaxies. I wonder if there is a theoretical limit on the numbers of galaxies despite there being a lot of space in 'Space'? Assuming that there isn't an infinite amount of space, we can safely say there are a finite number of galax...

Some of those clouds look Lenticular...or is that just appearance from a longer exposure? Really nice display!! :---(===) * Hi Boomer12k :) In a description with the image in Daniele Boffelli's section in 500px (found through his name link to his Facebook account) it states "One of the most am...

It's a great image.

I must be finally learning things from APODs as even I spotted the Horsehead Nebula before I saw the excellent annotated rollover. <<< There isn't a horse smilie so I used the puppy one instead!

Thank you Ann for your help in answering my query.

I think the red arc to the left of Orion is Barnard's Loop, but I'm wondering what is the red area just above Orion?

Thanks neufer for the confirmation that NGC 3165 is not in the image .

I would be grateful if someone could please confirm or not that the "smaller, dimmer NGC 3165 at bottom right" is visible in the image. Before I read this discussion I thought it must be the faint smudge just below and right of NGC 3166, but the APOD of March 28 2013 shows a bright object ...

Wow that was a quick response geckzilla .

I'm surprised that at least the SOHO media people have apparently not noticed the error. I will however take it no further.

In the information brought up through the "video" link in the explanation it states of the video "Published on Oct 30, 2015. Credit: NASA, SOHO Observatory. Occurred in 2014 November", but at least the "Occurred in 2014 November" is wrong as the event was in November 20...

That's an amazing image! :shock: Can't remember the last time I thought a building looked scary, but this one fits the bill. My first impression was that it was a huge, decrepit castle straight out of Dracula territory, but then I saw the person - I swear it looks like two persons!!! - standing in ...

It's a terrific image, but did it need to be so large? To see it all in one view I had to reduced the screen size on my laptop (which has a good size screen) but that makes the text small. There has been a trend for sometime now to issue APOD images that are much larger than they used to be. Is it n...

Thanks Chris for your very helpful answer to my query. Your regular willingness to help me despite perhaps my too many queries is much appreciated.

In information with the image in Ken's website it lists the exposure details, which add up to 17 hours. Will the individual exposure times be concurrently acquired, as if not then the 17 hours will mean at least some data must have been acquired in daylight (unless they were acquired over differing ...
