The Hubble Space Telescope, 32 years after its launch, broke the all-time record for most distant star. It won't do better.
The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
Due to a crust of carbon, the absence of oxygen, and constant bombardment from meteorites, the planet Mercury may be littered with diamonds.
A radical redesign of commercial aircraft, called the flying-V plane, could increase fuel efficiency by 20%, greatly reducing emissions.
On Nov. 13, 1946, a scientist dropped crushed dry ice from a plane into supercooled stratus clouds.
Revolutionary techniques for understanding brain functions in animals could soon help us understand how emotions guide our lives.
Mutations that confer malaria resistance occur more frequently in people who live in regions where the disease is endemic.
To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.
For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?
COVID-19 and other microbes have shed light on disease spillover from animals to humans, but we can also spillback disease to wildlife.
Murmurations have no leader and follow no plan.
From life on Earth to the planet itself, there are four ways our planet will actually experience "the end," no matter how we define it.
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
Javelin missiles have been an effective force multiplier, the latter-day equivalent of the sling that David used against Goliath.
Galactic archaeology has uncovered a spectacular find: the Milky Way already existed more than 13 billion years ago.
Chimpanzees are able to consider the context of social interactions and can accept unfavorable outcomes — sometimes.
Multiple lines of evidence — physical, chemical, and biological — must converge for scientists to conclude that alien life has been found.
The way that the ancient Megalodon adapted to water temperature has important implications for modern marine creatures.
Could we all attain this superpower?
Even a tiny sliver of the Universe can reveal the cosmic story of what's out there and how it came to be the way it is today.
Michio Kaku predicts, among other things, how we'll build cities on Mars and why cancer will one day be like the common cold.
Can a non-native species be a friend instead of a foe?

Where the prime meridian meets the equator, a non-existent island captures our imagination — and our non-geocoded data.
The closest star system to Earth, just over 4 light-years away, has three stars and at least one Earth-sized planet. Is it time to go there?
