The video starts a long way and then zooms into the center of the Lagoon Nebula, which is about 4000 light-years from Earth. Herschel 36 is the most prominent star emitting strong radiation and stellar winds that push the dust away in "curtain-like leaves," NASA said. You can see dark, elephant-shaped material that resists erosion and serves as an incubator for new star formation.
NASA used the Wide Field Camera 3, which works in the visible light to create the video. The fourth-generation instrument was added to Hubble in 2009 and is by far the highest-resolution camera on the Space Telescope. NASA can also switch to a near-infrared channel, which penetrates much of the dust and exposes an incredible number of stars in the fog, as shown in the following figure.
Although publicly outreach is actually a pretty big part of his mission, Hubble is good for more than just taking beautiful pictures. For example, it has been a crucial tool in the discovery of exoplanets as it has recently shown that the Trappist 1 planets can have water by scanning the starlight through their atmosphere.
New bodies within our own solar system have also been discovered. Impact sites of Comet Shoemaker-Levy 9 on Jupiter and pictured "deep field" views that reveal galaxies billions of billion light-years away, including the farthest-established site, GN-z11. It also turned out that black holes are common in the center of galaxies and are not as rare as one might think.
Similar to the Mars Opportunity Rover, Hubble has already flown far beyond his expected mission life, though he got off a very bad start with a flawed mirror. The last service mission to install the aforementioned Wide Field Camera 3 was carried out in 2009 by the Space Shuttle Atlantis Crew. Hubble will eventually be replaced by the James Webb Space Telescope (JWST), but NASA has recently extended its operational life to at least 2021. It could take even longer, given the recent one-year startup delay for the JWST. 19659006]
