The world is less prepared for a pandemic than before COVID. Here’s why
As world health leaders face deadly outbreaks of hantavirus and Ebola, a major pandemic preparedness report finds we are less safe from viral outbreaks than before COVID

The heart of galaxy M77 shines brightly in this May 7, 2026, image from NASA’s James Webb Space Telescope. The intense glow is due to gas being pulled by the strong gravity of the central black hole into a tight and rapid orbit around it. The motion of the gas causes it to heat up, releasing tremendous amounts of radiation.
The bright lines radiating out of the center are diffraction spikes. The spikes are not a physical feature of the galaxy, but an optical effect caused by the telescope itself.

See a Lincoln Memorial-sized asteroid pass within just 56,000 miles of Earth today
The asteroid will swing by Earth on Monday and be close enough to be visible using an amateur telescope
What If the Universe Had No Beginning? Part 3: A Universe From Nothing
Run Hawking's machinery and out pops something startling: the most likely universe looks an awful lot like ours, complete with inflation, a low-entropy beginning, and an arrow of time. All of cosmology, falling out for free. Almost.
The Milky Way's Turbulence Distorts Light from Distant Quasars
We may be getting better images of the Milky Way's supermassive black hole in the future. Astronomers used 10 years of observations of a distant blazar to detect turbulence in the Milky Way's interstellar medium. This turbulence makes images of Sagittarius A-star blurry.

New Algorithm Cracks the Asteroid Routing Problem
The Traveling Salesman is a classic problem in mathematics that requires a solution to the most efficient path to take to visit a given number of cities in the least amount of time. But scale this relatively simple concept up to space travel and the calculation becomes much more complex. Instead of visiting a stationary spot on Earth, when calculating the most efficient path to visit asteroids you must account for the fact they are traveling tens of thousands of miles an hour, and their exact position will change based on when a spacecraft leaves. This is known as the Asteroid Routing Problem, and a new paper from a group of Canadian and European researchers lays out a framework that can find the exact solution to any particular combination of asteroids to be visited.

Sharla Boehm, a math teacher, spent her summers coding. She’d go on to build what would eventually evolve into the Internet
What's Feeding Our Supermassive Black Hole?
Astronomers have identified the likely source of gas that flows into the maw of the Milky Way’s central black hole, Sagittarius A*.
