We present 15-20 μm spectral maps toward the reflection nebula NGC?2023 obtained with the Infrared Spectrograph in short-wavelength, high-resolution mode on board the Spitzer Space Telescope. These spectra reveal emission from polycyclic aromatic hydrocarbons (PAHs), C60, and H2 superposed on a ...
M20 is the famous Trifid Nebula, a bright colourful emission and reflection nebula that's located in the constellation of Sagittarius. At magnitude +6.3, it's visible with binoculars. This remarkable object not only contains an emission and reflection nebula but also a ...
Messier 42 - M42 - The Great Orion Nebula (Emission/Reflection) M42, also known as the Great Orion Nebula or Orion Nebula, is the prime deep sky attraction in the constellation of Orion and a showpiece deep sky object. With an apparent magnitude of +4.0, it's easily visible to the nake...

We have mapped the NGC 2023 reflection nebula in [CII] and CO(11--10) with the heterodyne receiver GREAT on SOFIA and obtained slightly smaller maps in 13CO(3--2), CO(3--2), CO(4--3), CO(6--5), and CO(7--6) with APEX in Chile. We use these data to probe the ...

Red Emission In Reflection NebulaDr Morbius
The newly-commissioned University of New South Wales Infrared Fabry-Perot\n(UNSWIRF) has been used to image molecular hydrogen emission at 2.12 and 2.25\nmicrons in the reflection nebula Parsamyan 18. P 18 is known to exhibit low\nvalues of the (1-0)/(2-1) S(1) ratio suggestive of ...

Having no any explanations the radiation of high-frequency components of the\npulsar in the Crab Nebula can be a manifestation of instability in the\nnonlinear reflection from the neutron star surface. Reflected radiation it is\nthe radiation of relativistic positrons flying from the magnetosphere ...
