Black Holes
In July 2026, Europe's Euclid telescope found 31 of the oldest quasars ever seen, two now shining with the light of a trillion suns when the cosmos was just 5 percent of its present age — their glow 13 billion years in the coming
Cosmology
We tend to think of the universe as roughly uniform, with galaxies scattered in every direction — but the Boötes Void, discovered in 1981 during a redshift survey, is a vast cosmic underdensity up to 330 million light-years across, containing only a few dozen known galaxies where thousands might otherwise be expected
Cosmology
On a September night in 1999, a 25-year-old graduate student stepped into a modest wooden shed in a Colorado parking lot and used a tiny four-inch telescope to spot a 1% dip in a star's light—a backyard experiment that proved alien planets could be tracked by their shadows and opened the floodgates to discovering thousands of worlds
Cosmology
There is a cloud of alcohol drifting through the constellation Aquila that is 1,000 times the diameter of our solar system and contains enough ethanol to make 400 trillion trillion pints of beer — and nobody has any commercial way to reach it, which is probably for the best
Cosmology
Scott Kelly spent a year in orbit while his identical twin brother stayed on Earth, and when he came home NASA discovered his gene expression had changed in ways that didn't fully reverse
Cosmology
The bacteria living in and on your body outnumber your own cells, which means that by strict cellular count you are not majority human — and the ratio shifts noticeably depending on whether you've just been to the bathroom
Cosmology
Japan sits on the intersection of four tectonic plates and experiences roughly 1,500 earthquakes a year, which is why the country's building codes are the strictest on Earth — and why the Tokyo Skytree, the second-tallest structure in the world, is designed to sway rather than resist
Cosmology
China's Chang'e 5 mission returned lunar rocks dated to 2 billion years old — 800 million years younger than anything Apollo brought back — which means the Moon was geologically active hundreds of millions of years later than every textbook had assumed, and most of those textbooks haven't been updated yet
Cosmology
The James Webb Space Telescope has found galaxies that appear to have formed within 280 million years of the Big Bang, some containing heavy elements that shouldn't have had time to form — and at least one peer-reviewed paper has now proposed that the universe might actually be 26.7 billion years old, almost twice the standard estimate
Cosmology
Every breath you take contains atoms that were once inside the lungs of Julius Caesar, Cleopatra, and every other person who has ever lived — the math is unforgiving and it works out every time
