Re: APOD: Exploring the Antennae (2017 Apr 28)

The 'Hubble' in the credit is a link to the HubbleSite. On that webpage there is a link to a 'Space Telescope Live. Look at what Hubble is seeing right now!' webpage https://spacetelescopelive.org/ that is stated to show what Hubble is looking at. I did not know of such a webpage and so I thought I...

Re: APOD: NGC 4302 and NGC 4298 (2017 Apr 21)

The "Virgo Galaxy Cluster" link https://apod.nasa.gov/apod/ap150804.html brings up the APOD of August 4 2015. Clicking on that image (at least when online) brings up a very useful annotated version on which NGC 4302 and NGC 4298 can be found labelled in the lower right quadrant of the image.

I profess to not understanding what this APOD is all about but nevertheless I find it very fascinating. I'm glad though that, as far as I can tell, my actions I've not split the Universe....or have I? :wink:
