It is fun looking back in time billions of years, then comparing the present to the past. Makes one wonder what is going on in the present. More precisely, here on earth, the present, looking through Hubble, is linked with with the past, therefore is the earth actually in the present or past? No offense intended, just being playful this AM.
Yes, it can be fun looking back in time, for instance at andromeda V73 or pulsar 445 W3, or even globular cluster 576T, but sometimes it can be hard to dig up some of those old memories, too.
Man do I ever agree. The Hubble may be the one best scientific investment in history.
