Nebulae usually consist of Hydrogen and Helium, as these are the most common and stable compounds in theUniverse. The formation of a nebula can occur when a star undergoes a significant change, such as excess fusion in its core. In the case of a planetary nebula, the formation of this dee...
Two different views of the Horsehead Nebula. On the right is a view of the nebula in visible light, taken using the European Southern Observatory’s Very Large Telescope in Chile (eso0202a). The new image on the left shows the nebula in the infrared, using observations from Hubble’s high...
We present observations taken with SCUBA on the JCMT of the Horsehead Nebula\nin Orion (B33), at wavelengths of 450 and 850 \\mum. We see bright emission from\nthat part of the cloud associated with the photon-dominated region (PDR) at the\n`top' of the horse's head, which we ...
The Orion Nebula is a nursery for new stars. 6 Aurora Dependent on geomagnetic activity. The aurora is more intense during periods of high solar activity. 5 Nebula Found throughout galaxies, including the Milky Way. The Horsehead Nebula is a famous dark nebula in the Orion constellation. 5 ...
I think its probably my processing that is the area that's holding me back the most especially the curves, stretch and somehow bringing out the colours better. With this one i struggled to know how black the sky needs to be. 2hrs 20 at F2 seems to have captured a lot of nebulosity. ...
Here is the Horsehead nebula. https://www.cloudyni.../#entry13885269 Note this was using a 5” Apo with military grade night vision attachment. My guess is you were looking at Orion Nebula. It is nearby in the sword of Orion. A cheap finder on an entry level scope could be off that...
A nebula, named for the Greek word for ‘cloud,’is in fact an interstellar cloud of dust and gas.Like the clouds in the sky, nebulae come in interesting shapes like flowers, insects, animals or people.This is how many of them get their names.There are four main types of nebulae....
I was~seeing~ the Horsehead Nebula at 1x.Never would have thought that possible. Using two viewers made the difference. And at 1x, the images merge perfectly without having to strap the two monoculars together. My eyes are PRK corrected to 20/12.5; I think that ...
Yea, thanks for reminding me of another wow moment. As a child looking out of my bedroom window at the summer Milky Way, back in the day when skies were truly dark, I "discovered" the lagoon nebula with my naked eye. Through a window, no less... Comet West rising before the ...
nebula, since the star is centered in the frame, it appears to the left and right in both HA and SII, but also very faint. I still think filter orientation might be in play here as the halos are not as extreme in my examples of the Astrodon filters compared to the Astrobin link...
