Bio SOFIA is the worlds largest flying observatory. It is a Boeing 747SP aircraft modified to carry a 2.7-meter telescope and a joint project of @NASA and @DLR_en. Location California Tweets 4,6K Followers 76,1K Following 684 Account created 20-10-2008 22:57:21 ID 16876667
iPhone : +89° 15′ 50.8″NASA Armstrong Massive stars like these are born deep inside celestial clouds. They are invisible to the light our eyes can see, but are bright when observed with infrared light like in the above image. 😊
Twitter Web App : NASA JPL If magnetic fields inhibit the gravitational collapse of celestial clouds in other regions of the galaxy, the number of new stars may be lower than current models predict. go.nasa.gov/2yTwC6B
Twitter Web App : An instrument built by NASA JPL reveals new details: Magnetic Fields. It uses infrared light to study dust grains, which align along magnetic fields, letting scientists infer the shape and direction of the otherwise invisible magnetic fields.
Twitter Web App : Orion is only 1,500 light years away, making it one of the closest stellar nurseries to Earth. Its clouds collapse under gravity to form massive stars. But something is preventing them from collapsing as efficiently as they could.
Sprinklr : A new view of the Orion Nebula reveals magnetic fields, shown as streamlines. These invisible forces are preventing star-forming clouds from collapsing under gravity — slowing the formation of new stars. go.nasa.gov/2yTwC6B
Twitter Web App : Astronomers call these effects "feedback.” They regulate the physical conditions of the nebula, influence star formation activity, and ultimately drive the evolution of the interstellar medium, the space between stars.
Twitter Web App : This bubble disrupts star birth in the cleared out area. But at the same time, the bubble pushes molecular gas to the edges, creating new regions of dense material where future stars might form.
Twitter Web App : At the heart of the nebula is a small group of young, massive stars. The brightest of these is creating a wind so strong that it has blown away the seed material for new stars — creating a large bubble — like a snow plow clearing a street by pushing snow to the edges. pic.twitter.com/SJ06gRtPgp
Twitter Web App : The nebula is the closest stellar nursery to Earth, where scientists can study how stars are born. But a veil of gas and dust shrouds the entire process from view. So scientists must use infrared light, which pierces through the cloudy veil.
