It's Halloween, and your favorite space agency is certainly in the holiday spirit.

In the days leading up to Oct. 31, NASA has been sharing photos of stars, galaxies and nebulas that appear as "galactic ghouls," "cosmic pumpkins," and "fiery jack-o’-lanterns."

The space agency, whose name on Twitter is now "NASA, but Sp🕸️🕸️ky," captured the images through various missions, like the Hubble Space Telescope and Spitzer Space Telescope.

"👀 When we peer deep into space, we don't expect to find something staring back at us...," NASA wrote, sharing a photo of a head-on collision between two galaxies that looks like "an uncanny pair of glowing eyes."

This galactic ghoul, captured by @NASAHubble, is really a head-on collision between 2 galaxies. Get spooked & find out what lies inside this ghostly apparition: https://t.co/xV2KiWphxf pic.twitter.com/dZnn70C1ty — NASA, but Sp🕸️🕸️ky (@NASA) October 29, 2019

It takes more than a candle to light this cosmic pumpkin. 🎃 In this image from @NASASpitzer, a massive star in the center of a cloud of dust and gas creates what researchers have nicknamed the "Jack-o-lantern Nebula."
