WHAT IS THE BIGGEST THING IN THE UNIVERSE??

Blog#494

Welcome back,

Saturday, April 5th, 2025.

The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall.

This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across! However, this is not really a ‘celestial body’ – a term which normally implies a tightly-bound object like a star or a galaxy.

The largest known elliptical galaxy is thought to be IC 1101 (with a diameter of four million light-years), and the largest known spiral galaxy is Malin 1 (with a diameter of 650,000 light-years).

Meanwhile, the largest star by radius is thought to be UY Scuti, a red hypergiant star in the constellation of Scutum that has an estimated radius of over a billion kilometres – 1,700 times that of the Sun.

The James Webb Space Telescope’s observation of the Crab Nebula—the supernova remnant produced by one of the earliest supernova explosions ever recorded by humans—is now a printable poster!

The poster is available single- and double-sided. The double-sided version includes the image on the front and a description in both English and Spanish on the back.

A star in Pismis 24 was once thought to be 200x the Sun’s mass, making it one of the most massive ever found. Hubble later revealed it’s actually at least three stars, each still near 100x solar mass. Below, young stars continue to form as energetic giants illuminate the nebula.
