Emission Nebulae are those that emit radiation from ionized gas and are often called HII regions because they are largely composed of ionized hydrogen. The Orion Nebula is an emission nebula and star-forming region. Not only is it thebrightest nebulain our sky, but it is also the most active...
a cloud of gas and dust that is only visible because of bright nebulae and stars behind it.Like a shadow or a silhouette,they take their shape from the light we do not see.One of the most famous dark nebulae is the Horsehead Nebula.It is easy to see where this nebula got its name!
I think ive just about got the spacing right. As i understand the Samyang 135mm is actually a 130m FL. So the proof of proper spacing is that images plate solve as close as possible to 130mm. i think these solve at 129.82mm. So if i can find a 0.2mm spacer i might add that. ...
哈勃看到不同颜色的马头星云(Hubble Sees a Horseheadof a Different Color) 天文学家已使用NASA的哈勃太空望远镜在新的红外光下拍摄了标志性的马头星云,以纪念著名天文台在1990年4月24日发现号航天飞机上发射23周年。 鹰星云柱(Eagle Nebula Pillars) 像海底畜栏?像魔法城堡?像太空蛇?这些...
I also made a brief attempt at IC 4592 (Blue Horsehead Nebula), but was not able to identify it either. Once I settled on M57 I found it easily. Being able to identify Vega, I was able to clearly see Lyra. M57 is easily located almost on the line between Sulafat (...
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 ...
(bottom right) — and scores of explorable planets, from Mars to the Horsehead Nebula. But for all BioWare's work on the fantastical creatures and locales, the biggest challenge was designing humans like Shepard that didn't look like creepy mannequins. "We spent a lot of time on the ...

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 ...
The Horsehead Nebula is a famous dark nebula in the Orion constellation. 5 Aurora Visible effects of solar particles colliding with atmospheric gases. We camped under the stars hoping to catch a glimpse of the aurora. 3 Nebula Sites of complex chemical processes. Nebulae play a crucial role in...
