This Is How NASA Celebrated Halloween With 5 Stunning Astronomical Images
From a galactic spook to a skull-like dead comet.

Halloween is celebrated when people come together to carve pumpkin lanterns and throwing costume parties. But the US based space agency chose a different path than traditional method, sharing a collection of creepy cosmic happenings in the universe.
“Is that a skull spotted in the Pereus Cluster of galaxies?” asked NASA in the first image. “This X-ray image was captured by the Chandra Observatory.”
MyCn18, or the Hourglass Nebula, is the second photo shared on NASA’s social media accounts. An eye-shaped view is clearly seen. This nebula –located 8,000 light years away– is a young planetary nebula that surrounds a dying star, and it was captured by NASA’s Hubble Space Telescope.

As for the third image, you can see a galactic spook with sharp eyes spotted by Hubble. There are actually two colliding galaxies.
NASA’s Solar Dynamics Observatory recorded the fourth photo resembling Jack-O-Lantern face, in which the Sun’s active regions can be seen.

The last image of the series is about a skull-like dead comet. “The radar images were generated by the National Science Foundation’s Arecibo Observatory in Puerto Rico,” said NASA.
To remind, this observatory collapsed before controlled demolition. We reported on November 21, 2020 that Arecibo telescope would be dismantled permanently due to the broken two cables supporting the system, of which engineers said it was unfeasible to mend it safely.
