This is a newly released Hubble image of the Lagoon Nebula, otherwise known as Messier 8 and the star cluster NGC 6523. It lies 4,500 light-years away in the constellation Sagittarius. Image credit: NASA, ESA, J. Trauger (Jet Propulson Laboratory).This new NASA/ESA Hubble Space Telescope image shows the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
James Webb Space Telescope’s mirrors and science instruments have been mechanically attached to the observatory’s sunshield and subsystems, a major milestone for engineers building the infrared telescope. Launch from French Guiana remains targeted for 2021.
The Helix Nebula is a familiar target to amateur astronomers, a dim, eyepiece-filling doughnut that belies the complexity revealed by spectacular images from the Hubble Space Telescope and other sensitive instruments.
Observations by the Hubble Space Telescope and ESO’s Very Large Telescope indicate processes that may limit the habitability of planets orbiting dwarf stars.
