Astronomy picture of the Day - Unexpected Clouds Toward the Andromeda Galaxy

Explanation: Why are there oxygen-emitting arcs near the direction of the Andromeda galaxy? No one is sure. The gas arcs, shown in blue, were discovered and first confirmed by amateur astronomers just last year. The two main origin hypotheses for the arcs are that they really are close to Andromeda (M31), or that they are just coincidentally placed gas filaments in our Milky Way galaxy. Adding to the mystery is that arcs were not seen in previous deep images of M31 taken primarily in light emitted by hydrogen, and that other, more distant galaxies have not been generally noted as showing similar oxygen-emitting structures. Dedicated amateurs using commercial telescopes made this discovery because, in part, professional telescopes usually investigate angularly small patches of the night sky, whereas these arcs span several times the angular size of the full moon. Future observations -- both in light emitted by oxygen and by other elements -- are sure to follow.

Gorgeous. The blue streaks look like asbestos fibers in the microscope.

FTA “”No one is sure.””

Now THAT is real science! We can be sure of many things, and we will no doubt determine much more. A quote, attributed in various forms to several wise people: The Beginning of Wisdom is the Ability to State :I don’t know.’

They need to make a public excuse as to why amateurs discovered this first?

It seems the professionals with "professional telescopes" couldn't see the forest from the trees.

And I'm still not sure what a professional telescope is.

I may be wrong, but what I think that means is amateurs who use their professionally made scopes to take photos of huge areas of the sky will have pictures similar to this, although I canā€™t recall seeing one processed to look like that.
Professional astronomers, using their ā€œmonster-sizedā€ observatory scopes will take photos of extremely small areas of the sky, but with much more magnification.

all I did was google “red gas nebula” because the red gas cloud photoshopped in looked familiar... I viola... within the first 6 pics I found a match!!

Lol... They did a pretty job making the picture, but its still fake!

There are many research grade scopes that provide wide angle field of views.

And speaking of wide angle..

“WASP or Wide Angle Search for Planets is an international consortium of several academic organizations performing an ultra-wide angle search for exoplanets using transit photometry. The array of robotic telescopes aims to survey the entire sky, simultaneously monitoring many thousands of stars at an apparent visual magnitude from about 7 to 13.”

I hadnā€™t heard of WASP. Thanks for the update.

That is so true! I get sick of listening to astronomers and astrophysicists who state theory as if it is proven fact.
