I was just going to say this. It appears the date is missing a digit.

It's very cool that one individual was able to travel to each of those places to capture these images!

As far as the "small rock... stuck into one of Curiosity's aging wheels", is it the right front wheel? ... And the wheel directly behind that front one looks like it has a hole in it as well. Or is one of those spots the rock? On right-middle wheel (especially in the enlarged view), I see...

Very interesting image. As far as the "small rock... stuck into one of Curiosity's aging wheels", is it the right front wheel? The enlarged image shows what looks like several holes that've been punched in the wheel: one towards the upper portion where the tread sorta zig-zags, and the oth...

The APOD FaceBook page, at least, has such an announcement... The APOD for 2017 Oct 16 will be delayed pending an announcement from the NSF and the LIGO and Virgo collaborations at 10 am EDT. Rob Thanks Rob. Not on Facebook, but I (finally) did notice the announcement the bottom of yesterday's imag...

Instead of yesterday's image, why didn't they have a some kind of announcement saying that?
I thought the site was hacked or something.

This is a very ineresting image.
And I also have a question about the colors: or more specifically, what is the difference between 'hydrogen alpha emission' that are colored red, and 'hydrogen series emission', colored blue and purple?

TIA

Wow, what a way to experience the eclipse! Excellent image!

I did, to Western KY, and it was the most amazing thing I've ever seen:

... with neighboring galaxy NGC 4562 at the upper left. Would someone please point out where exactly this galaxy is? (in a screen-shot, maybe?) I've looked and looked, and am just not seeing it... :( TIA NM: Found it. Just have to click on the 'included in the pretty field of view' link. :ssmile:

What a great APOD! Love it

Very nice image - Happy Valentine's Day, APODees!


(or is it: APODers?)

x2. And also, the 'back' arrow doesn't take you to yesterday's APOD, it jumps back to 1 Feb's image. Just FYI.


However, today's image is very beautiful!

The clouds really do resemble oyster shells.
Very nice image!

(I should've known.....) Thank you!

Can someone please point out the fourth planet? I found Mars and Saturn (towards the left), and Jupiter (far right), but cannot locate the fourth one.
Any help? And TIA

This is an awesome APOD! I especially like that some 'geyser action' can be seen.
Very cool!

Thank you for your explanations, Paul and Ann. They definitely helped!

Morning all! My question is regarding the phrase 'active galaxy'. I know that M31 (Andromeda) is the closest galaxy to us, but why is this galaxy considered the closest 'active galaxy'? What makes a galaxy 'active'? (And why is M31 not - or no longer - classified as active?) And this is a beautiful ...

These 'traced-over' images are great! At least now I can see the resemblance. Or resemblances..?
And 'Pterodactyl Nebula' sounds good to me!

Confession: I've never been able to see a pelican in this nebula.
(Is there an 'outlined image' somewhere that someone could point me to? TIA!)

And this is a gorgeous image!

Nitpicker wrote:Wow. It pays to click on the image and check out the full-res version. It is much wider.

x2.
I was just going to say that the full-res version is absolutely gorgeous!

It looks like LMC and SMC or Red Aurorae but ???

I thought they looked like sprites!

Why did they build a fence in Antartica? ...keep the penguins out? I wondered that too! :lol2: I also wondered about the 'asymmetry' that another poster pointed out. And doesn't the foreground portion of the image look a little strange with the shadows not 'right', in relation to the sun? :o But de...

HAPPY BIRTHDAY APOD!!!!

Is this the reason that I haven't been able to view the image of the day since Friday? 'Otto' is on some sort of vacation/hiatus/MIA..?
