As families sit on benches to watch Charlie Brown help his friend Linus, waiting for this Great Pumpkin HalloweenThey might be surprised to learn that NASA has discovered a “bigger pumpkin”.
Image from NASA’s The Hubble Space Telescope showing what looks like a giant lantern in the sky. “Pumpkin” is actually a picture of the first phase of the collision between two galaxies.
The pumpkin’s face consists of two red old stars, forming the eyes and giving the region an orange glow, and a curved, blue smile is formed from newborn clusters. With a scattering of blue stars in the foreground, it looks like a pumpkin sparkling Halloween.

This “great pumpkin” is of course much larger than the one made by Charlie Brown. The entire scene spans nearly 109,000 light-years, the same size as ours Galaxy according to NASA.
While the area now looks like a Halloween pumpkin to us, the shape will soon disappear as pairs of colliding galaxies become more intertwined. NASA predicts that this pair of stars, 120 million light-years away in the constellation Canis Major, could become a giant spiral galaxy. The “smile” could be the beginning of that vortex rebuild, researchers say. Image description of NASA. The arm of a smile embraces both galaxies and is most likely formed when interstellar gas is compressed when galaxies begin to merge.
Most of the time, when two galaxies collideThey lose their typical flat disc shape and stars in each galaxy are shuffled into a new soccer ball-shaped space, NASA said. In the end, they form an elliptical galaxy.
If the “bigger pumpkin” turns into a giant spiral galaxy, that would be a rare feat. There are only a few other examples in the universe, including Rubin’s galaxy, the astronomers said in NASA’s statement.
The mystery and attraction surrounding these two colliding galaxies would turn out to match its reputation as the “bigger pumpkin”. In “It’s The Great Pumpkin, Charlie Brown,” poor Linus has never seen the mysterious great pumpkin that he was so excited about.
