In a composite picture of the Swan Nebula, SOFIA has identified some blue spots close to the core and some others green. Spitzer spotted the white star area. The picture of SOFIA unveils proof that elements of the nebula have been developed separately to reach the swan-like form observed recently.
Swan Nebula or the Omega has represented an aim of astronomical study for 250 years, but until now, astronomers couldn’t get a clear view of the core of the structure. With the help of SOFIA (the Stratospheric Observatory for Infrared Astronomy), we can now take a sneak peek at the Swan Nebula.
SOFIA is NASA’s flying observatory, a bunch of tools aboard a revamped Boeing 747SP jetliner aircraft. The device can fly hight into our planet’s atmosphere over the broad majority of water mist. By doing that, its sensitive tools can identify infrared signals that are very low or far away.

In contrast, usually, the cloud would intervene with those signals and make it challenging to discover. Moreover, thanks to the tools such as the German astronomer handset at GREAT (Terahertz Frequencies), SOFIA can identify infrared light from distant clouds. By glancing into the infrared wavelength, those tools can see through the sand clouds that produce fog.
NASA’s moving observatory also allows researchers to gaze in and notice spots near the core of the structure. “The current mist has the secrets that reveal its past; we should only be able to discover them. SOFIA lets us do this so that we can understand why the mist looks like today,” stated scientist Wanggi Lim.
However, the sand is the only one that makes it hard to view the stars in the core of the nebula. The inner place shines brightly, so identifiers on almost all telescopes are immersed, “similar to an overexposed photo,” according to NASA. SOFIA utilizes a device dubbed the FORCAST, which can see into the core of the nebula and examine the various area within it, unveiling those places in different discharges of star birth over nebula’s records.
