Good Red Friday morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Central Lagoon in Infrared." The Lagoon Nebula (M8) is found in the constellation Sagittarius and lies about 1,000 light years from Earth. The central star, Herschel 36, is 30 times larger than our Sun. Using Hubble data, this infrared image of the Lagoon Nebula paints a much starker picture than the obscuring gas and dust that marks what can be seen in visible light (see below). I'll post the June 1, 2020 APOD in a separate comment for comparison.

APOD Background
"Explanation: Stars fill this infrared view, spanning 4 light-years across the center of the Lagoon Nebula. Visible light images show the glowing gas and obscuring dust clouds that dominate the scene. But this infrared image, constructed from Hubble Space Telescope data, peers closer to the heart of the active star-forming region revealing newborn stars scattered within, against a crowded field of background stars toward the center of our Milky Way galaxy. This tumultuous stellar nursery's central regions are sculpted and energized by the massive, young Herschel 36, seen as the bright star near center in the field of view. Herschel 36 is actually a multiple system of massive stars. At over 30 times the mass of the Sun and less than 1 million years old, the most massive star in the system should live to a stellar old age of 5 million years. Compare that to the almost 5 billion year old Sun which will evolve into a red giant in only another 5 billion years or so. The Lagoon Nebula, also known as M8, lies about 4,000 light-years away within the boundaries of the constellation Sagittarius."
