For the first time, observations with the Gemini Observatory clearly reveal an extreme, large-scale galactic outflow that brings the cosmic dinner to a halt. The outflow is effectively blowing the galaxy apart in a negative feedback loop, depriving the galaxy’s monstrous black hole of the gas and dust it needs to sustain its frenetic growth. It also limits the material available for the galaxy to make new generations of stars.

When two galaxies merge to form a giant, the central supermassive black hole in the new galaxy develops an insatiable appetite. However, this ferocious appetite is unsustainable.For the first time, observations with the Gemini Observatory clearly reveal an extreme, large-scale galactic outflow that brings the cosmic dinner to a halt.

M1 expansion over 9 years
http://www.emilivanov.com
Copyright 1st image: Niki Petrov, Galin Borisov, Emil Ivanov
Copyright 2nd image: Niki Petrov, Yanko Nikolov, Emil Ivanov Two days after I posted my previous post "M1 Expanding", Niki Petrov sent me a raw material of earlier M1 image, taken on January 21st 2002 with 2m RCC telescope at NAO Rozhen. Thus I can present the expansion of the Crab Nebula over period of almost 9 years (the second image was taken on November 14th 2010 with the same telescope)
A mouseover version (better than this .gif image) can be found here:

The sky of the Mayas : a night in Tikal (Guatemala)
Tikal (or Tik'al according to the modern Mayan orthography) is one of the largest archaeological sites and urban centres of the pre-Columbian Maya civilization. It is located in the archaeological region of the Petén Basin in what is now northern Guatemala. Situated in the department of El Petén, the site is part of Guatemala's Tikal National Park and in 1979 it was declared a UNESCO World Heritage Site.

Stephane,
Very nice collection of images and video. I enjoyed them. How long were you there?

Very nice image! Very dynamic!
Re: Recent Submissions
Diana Juncher, it is nice to see a woman posting pictures here! I don't know Morse code, but I suppose you have written Vega's name in Morse code in the sky!
Fabiomassimo Castelluzzo and Stefano Conti, it is interesting to see your image of NGC 2841, particularly in view of the fact that it was APOD here just a few days ago. The galaxy looks very red in your picture.
Stéphane, I love your picture of Orion over Temple V. The composition is delightful, the cloud-flecked sky looks interesting, and I love the blue halo around Sirius!
Richard Yandrick, I'm bewildered by planetary nebulae because I don't understand their colors, but you picture looks very true-color and very interesting, so thanks!
ftherrmann, that animation showing the expansion of M1 over 72 years is hugely interesting. I wonder, however, if the film that was used to photograph M1 back in 1939 had the sensitivity to red Ha light that black and white film has today. It could be that the expansion hasn't been quite so great as it appears to be, but that modern film or CCD chips simply "sees" the red outer filaments of M1 better than the photographic plates of yore managed to do.

Re: Recent Submissions
Stéphane's pictures reminded of this APOD: http://apod.nasa.gov/apod/ap090411.html
I'm frequently frustrated when something humongous in real life (a mountain, a tree, a building, a Mayan temple perhaps) looks quaint and modest in my pictures of it. Not so in Stéphane's - compare the apparent size of Orion with your experience of viewing Orion in real life. Orion spans almost 19 degrees from Betelgeuse to Rigel, and really dominates its part of the sky, but in the pictures here it is a dwarf. Those temples must be really big!
It must have been an amazing experience, and congratulations on such great photos that show it!

Ann,
If you concentrate only on the size and movement of the filaments I think you'll agree that the Crab is expanding. Also consider that the older film exposures were done at the back end of a 4 meter scope compared to my 10" RC from the backyard. The CCD is indeed a great equalizer!
