NASA shared some interstellar fireworks to bring 2020 to an end. The Orion Nebula looks like a rainbow canvas peppered with dots of light.

NASA decided to share some interstellar fireworks to end an unforgettable year.

The agency posts an “image of the day,” every day, and the final image of 2020 did not disappoint.

A canvas of color, NASA’s December 31 image of the day depicts a composite image of the Orion Nebula, captured by the Hubble Space and Spitzer Space Telescopes.

It’s located more than 1,500 light-years away from Earth.

Nebulae like this one are interstellar nurseries – giant clouds of gas and dust in space that cradle infant stars as they’re born. Some nebulae form as stars die: As a star’s core cools, it starts to shed its outer layers, which disperse to form gaseous clouds

When space telescopes like the Hubble image the hydrogen, sulfur, and carbon molecules that make up nebulae like Orion they don’t capture color. Rather, Hubble records particles of light, which NASA can then view through different filters that only let in certain wavelengths of color. Then they assign color to the particles that come through those filters (light than came through the red filter is assigned a red color, for example.)

NASA’s Spitzer Space Telescope captured this image of the Helix Nebula, which is located in the constellation Aquarius-about 700 light-years away from Earth

By combining images of the same nebula viewed with different filters, the agency can create a composite, color image like the ones shown above

“We often use color as a tool, whether it is to enhance an object’s detail or to visualize what ordinarily could never be seen by the human eye,” NASA said.

There are roughly 3000 nebulea in our galaxy.

The closest known nebula to our planet is the Helix Nebula, the cosmic remnant of a dying star. It’s about half the distance from Earth as the Orion Nebula is – 700 light-years (so if you traveled at the speed of light, it’d take you 700 years to get there).

The Hubble Space Telescope has been imaging nebulae for 30 years, and these images help scientists learn more about how these cosmic clouds evolve, or even dim and shrink, over time.
