NASA’s latest “photo of the day” for 2020 depicts the Orion Nebula, located 1,500 light-years from Earth.
The Hubble and Spitzer space telescopes capture the stunning and colorful image.
Nebulae are giant clouds of gas and dust where new stars are born.
NASA decided to share some interstellar fireworks to end an unforgettable year.
Agency posts “today’s picture” Every day, the final image of 2020 did not disappoint.
It is located more than 1,500 light years from Earth.
Nebulae such as these are interstellar nurseries – giant clouds of gas and dust in space that incubate smaller stars as they are born. Some nebulae form when stars die: As the star’s core cools, it begins to shed its outer layers, which disperse to form gas clouds.
To the naked eye, nebulae will not, in fact, look like rainbow paintings filled with points of light (which usually appear to form new stars).
When space telescopes like Hubble visualize hydrogen, sulfur and carbon particles that form nebulae like Orion, They do not pick up color. Instead, Hubble records particles of light, which NASA can then see through various filters that allow only certain wavelengths of color. Then they assign a color to the particles that come through those filters (for example, the red color is assigned to the light that comes through the red filter)
By combining the images of the same nebula that are projected with different filters, the agency can create a color composite image like the one shown above.
“We often use color as a tool, whether it’s to enhance the details of an object or to visualize what the human eye would not normally see,” NASA said.
Almost there 3000 nebulae In our galaxy.
The closest known nebula to our planet is the Spiral Nebula, the cosmic remnant of a dying star. About Half the distance from the ground Like the Orion Nebula – 700 light years (so if you travel at the speed of light, it would take 700 years to get there).
