New data from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, reveal a three-dimensional (3-D) view of the Orion Nebula – Earth’s closest star-formation nursery – and a powerful stellar wind. Researchers can rotate, zoom in, and even dive through this data cube to better understand how stars are forming.

The Stratospheric Observatory for Infrared Astronomy, SOFIA, released new data from its recent Southern Hemisphere observations revealing the structure of celestial magnetic fields in the region known as 30 Doradus, or 30 Dor, at a scale that has never been seen before.
Two research teams used a map from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, to uncover new findings about stars forming in Orion’s iconic Horsehead Nebula. The map reveals vital details for getting a complete understanding of the dust and gas involved in star formation.
To have a full picture of the lives of massive stars, researchers need to study them in all stages – from when they’re a mass of unformed gas and dust, to their often dynamic end-of-life explosions.
Astronomers are observing star-forming regions in our galaxy with NASA’s flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments required to create the largest known stars, which tip the scales at ten times the mass of our own Sun or more.
An international team of researchers used NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, to make maps of the ring of molecular clouds that encircles the nucleus of galaxy IC 342. The maps determined the proportion of hot gas surrounding young stars as well as cooler gas available for future star formation. The SOFIA maps indicate that most of the gas in the central zone of IC 342, like the gas in a similar region of our Milky Way Galaxy, is heated by already-formed stars, and relatively little is in dormant clouds of raw material.
