The Atacama Large Millimeter/submillimeter Array (ALMA) and the 3.58-meter New Technology Telescope (NTT) team up for a very nice look at a newborn star. The colors and filters are explained in the ESO caption below, you might get a better sense of them by going to the ESO website. While you are there you can get desktop versions of the image, it looks good on mine.
Unrelated Observing note: The full moon was quite orange when it was setting this morning. Apparently the color I am seeing is from smoke high in the atmosphere from the fires in western Canada, that according to the local weather guy. He’s good like that, even announces visible Hubble passes.
Here’s the ESO caption:
This unprecedented image of Herbig-Haro object HH 46/47 combines radio observations acquired with the Atacama Large Millimeter/submillimeter Array (ALMA) with much shorter wavelength visible light observations from ESO’s New Technology Telescope (NTT). The ALMA observations (orange and green, lower right) of the newborn star reveal a large energetic jet moving away from us, which in the visible is hidden by dust and gas. To the left (in pink and purple) the visible part of the jet is seen, streaming partly towards us.
