NASA often shares images of the earth and space, which amazes social media users. This time, the space agency shared not one but four images of nebulae on its official Instagram page-gaseous clouds formed by stars. Sharing these breathtaking photos, NASA wrote in the caption: “Stars: They are just like us!” Before you wonder how we are similar to celestial bodies, the caption adds that even stars are ” Composed of hydrogen, helium and carbon”. NASA provided the background of the picture, indicating that the four nebulae captured in the photo are the Eagle Nebula, Omega Nebula, Trifid Nebula, and Lagoon Nebula.
In an Instagram post, NASA said: “Nebulae are breathtakingly beautiful star-forming clouds composed of gas and dust. The picture shows the four most famous images of nebulae taken by the Spitzer Space Telescope: the Eagle Nebula ( Including the Pillars of Creation), the Omega Nebula, the Trifid Nebula, and the Lagoon Nebula.”
The caption further states that nebulae exist in interstellar space, that is, the space between stars. “The nebula closest to the earth is known to contain the remnants of a dying star-probably like our sun, called the spiral nebula.”
So how far are we from the nearest nebula? According to NASA, it will take us hundreds of years to do this. “Out of about 700 light years away, even if you can travel at the speed of light, you still need 700 years to get there,” the headline said.
A user nicknamed “Joejoeboddie” responded to this picture: “It’s just… it’s beautiful.” Another user named “Raha Iran 72” said: “How small we are! It’s breathtaking.”
A user named “Spellbounded” wrote: “Satisfactory. That’s why I keep going.” Most others left heart-eyed emojis in the comment section.
According to NASA, a group of astronomers in the 1950s “conducted rough distance measurements of some stars in these four nebulae.” Therefore, the team was able to infer the existence of the Sagittarius arm, which in turn provided some preliminary evidence for the spiral structure of our galaxy.
The word nebula comes from the Latin word cloud or fog.
