The Hubble Space Telescope has re-imaged the Eagle Nebula, 20 years after it did so to mark 15 years of service. This time, astronomers have used new processing techniques to draw out additional details in celebration of the telescope's upcoming 35th anniversary.
What is it?
A cosmic cloud of cold hydrogen gas, this towering pillar is part of the Eagle Nebula. It is here where new stars are born among the collapsing clouds.
"Hot, energetic and formed in great numbers, the stars unleash an onslaught of ultraviolet light and stellar winds that sculpt the gas clouds around them. This produces fantastical shapes like the narrow pillar with blossoming head that we see here," reads a caption for the image prepared by the Hubble Space Telescope team.
The thick and opaque material in the pillar is outlined by the glow of more distant gas behind it. The blue colors in the background are from ionized oxygen; the red lower down is glowing hydrogen. Orange indicates starlight peeking through the dust: bluer wavelengths are blocked by dust, leaving only the redder light to shine through.
Where is it?
This 9.5-light-year-tall (or about 90 trillion kilometers) pillar is just a small section of the Eagle Nebula, also known as Messier 16. This tower of gas and dust is located near the iconic "Pillars of Creation" revealed by the Hubble Space Telescope in 1995 and 2015.
The Eagle Nebula is one of many nebulae in the Milky Way, located about 5,700 light-years from Earth.
Why is it amazing?
This image is part of a series of observations being made to mark 35 years of observations for the Hubble Space Telescope. Deployed into orbit by the space shuttle Discovery in April 1990, the orbiting observatory became famous for its ability to be repaired and upgraded by astronauts, enabling stunning views of our universe like this one.
