New view of the Orion Nebula
Brand-new data from the Atacama Large Millimeter/ submillimeter Array (ALMA), as well as other telescopes, has been used to create this stunning image that reveals web filaments in the Orion Nebula. They might look fiery and red-hot, but in reality they are so cold that only telescopes that operate in millimetre-wavelengths are able to observe them.
The Orion Nebula lies about 1,350 light years away from Earth, with this snap in particular combining data not just from ALMA but from the IRAM 30-metre telescope (red) and the European Southern Observatory’s HAWK-I instrument (blue). The grouping of bright blue-white stars, visible in the upper left, is the Trapezium Cluster, which is made up of searing hot, young stars only a few million years old.
