A really great picture!
I wonder why and how it is that the area bottom-left of the horsehead is sharper than the rest. Does anyone of you have any ideas?

You are right! If you have a close look, you can even see some background nebulae! ... Really great stuff!owlice wrote:There are also some lovely spirals!Hofi wrote:Great image! I like the background galaxies most! There are really nice edge-on ones!

Re: APOD: M72: A Globular Cluster of Stars (2010 May 12)
I was wondering some of the same things that tesla (above) mentioned. What is different in the gravitational forces that cause some globular clusters to apparently resolve themselves into a disk-like galaxy as our galaxy but others still remain as globular clusters? What kind of rotational motions ...

Re: MilkyWay@Home
MilkyWay@home sounds a good idea. But I cannot remember to have heard any results from SETI@home and EINSTEIN@home. Does anyone of you know whether there have been results, yet? If the amount of computing power is really so great, there should have been some nice finds.

You cannot say exactly! Humans would see it gray because the colors are so faint that our eyes would not recognize it.gravi wrote:if those are false colors what true colors it would be?

Currently, I have the Cat's Eye Nebular by Hubble hanging in my room. But I deliberate to change it into this one!

Great find, neufer! There are several such objects. Just look at the "North America Nebula" (NGC 7000)! I really like this similarities!

Hi! We all know that there are financial problems nearly all over the world. The shuttle was thought to be cheap because it's reuseable. Indeed, it did not work as planed. That's the reason why the USAF joined the project - because NASA had not the money to pay the expenses. In my opinion, the shutt...

WOW!
I like all of these images! They could have been taken on earth.
Viscous Flow in Protonilus Mensae look like there was plate tectonic forming canyons.

I like this photo. It shows the great height difference between the orbiter and the great fuel tank in the background.
I have one question: What are the dark spots left of the yellow retrainer? I don't think they are windows^^

Re: APOD: The Antennae (2010 May 07)
Last year, there was an eppisode of "Hubble's Universe Unfiltered" which discussed the topic of merging galaxies. There was also an animation which, in my opinion, was quite good.
You can find it here. Hope it helps.

Re: APOD: The Antennae (2010 May 07)
If this really is the photo of 2 galaxies that have collided, why do the curvatures in the tails become sharper as they collide? It seems the opposite would happen. Since we suppose that the galaxies are attracted to each other due to gravitational forces, the curvature lines should become more str...

Re: APOD: The Antennae (2010 May 07)
I cannot agree with you. If you rotate the image 180°, the tidal tales look like old TV-antennas (although one is bend a little bit). Of course you need a little bit of creativity to see it.Astronut wrote:Antennae? - not really.

Re: APOD: Sunset on a Golden Sea (2010 Apr 28)
Were the colours made more intense by volcanic dust ? Maybe not. Normally, sunset (and sunrise) colours can be still be very dramatic, especially when the atmosphere is clear and the Sun is viewed very near the horizon, as in this scene. Nonetheless, I would not agree with APOD Robot. I'm living in...

Is it actually better known why the axial tilt is 177.3°? I just have heard that Venus possibly was hit by a huger object. How sure do "we" know that?

Re: APOD: Northern and Southern Owls (2010 May 06)
The similarity of this nebulae is really astonishing!
While looking at them, a question penetrated into my mind: Why and How is it that the colors at the edge of the nebulae are stronger than in the inner side? Is it because of the higher density of material/gas?

Re: Favorite APOD
Hi!
I will add today's APOD to the list of favourites. The Faces of Mars. I really like the idea of letting children paint the planets. It helps increasing the fascination on the universe. The children of today are the (possible) astronomers of tomorrow!

I like this idea! And Mars is definitely the best object for such paintings through a telescope. My favourite image is the one by Pierre Desvaux. In my opinion, he got the colors as you would see them through a telescope. There has to be more to Mars than meets the eye when 24 different people look ...
