Astronomers have more accurately measured the distance to the oldest and farthest galaxy ever detected. The light they’re seeing left the galaxy, known as GN-z11, around 13.4 billion years ago, when the universe was a cosmic toddler, and this galaxy ma… Continue reading Astronomers precisely trace distance to oldest and farthest known galaxy
Earth isn’t the only place that’s heating up of late – the universe seems to be too. Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today t… Continue reading Mean temperature of the universe is rising over billions of years

It seems almost absurd now, but cosmologists once assumed that galaxies of a given type were all the same and didn’t change. Because of this assumption, galaxies were used as a redshift or light-based yardstick to measure distances in the universe. But what if some galaxies were intrinsically redder than others? Little to no thought was given to their origins, compositions, or evolution until Beatrice Tinsley came along.
Beatrice saw galaxies as changing bodies of stars. She believed that they grew, evolved, and died because they’re made of stars, and that’s what their star populations did. To lump all galaxies …read more

Thanks to gravitational lensing, astronomers can observe normal stars across colossal stretches of space and time. Continue reading At Nine Billion Light Years, ‘Icarus’ Is the Most Distant Star Ever Observed
