Patricia: I have always wanted to see the Northern Lights with my own eye, but never had a chance.  We're WAY too far south, and it's overcast right now anyway.

Have YOU been able to see the Light Show this week?

Why are the Northern Lights burning so bright?

I live in California, and Jupiter has been out for the last couple days, probably longer. I'm new to star gazing. And according to this site, I've been missing a lot more:

Ok, I've made my A/N donation......your turn.

The predicted merging of Andromeda & Milky way is interesting.  I'd like to be around 8 billion years from now to see it.

I think so, too.

Gemini legacy - photo of day   

Polar Ring Galaxy NGC 660   beautiful

"a sharp composite of broad and narrow band filter image data from the Gemini North telescope on Mauna Kea. Over 20 million light-years away and swimming within the boundaries of the constellation Pisces, NGC 660's peculiar appearance marks it as a polar ring galaxy. A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting in rings nearly perpendicular to the plane of the galactic disk. The bizarre-looking configuration could have been caused by the chance capture of material from a passing galaxy by a disk galaxy, with the captured debris eventually strung out in a rotating ring. The violent gravitational interaction would account for the myriad pinkish star forming regions scattered along NGC 660's ring. The polar ring component can also be used to explore the shape of the galaxy's otherwise unseen dark matter halo by calculating the dark matter's gravitational influence on the rotation of the ring and disk. Broader than the disk, NGC 660's ring spans over 50,000 light-years."

The solar eruption is not as amazing as the fact they can take a picture like this of a solar eruption.
