The James Webb Space Telescope's discovery of the universe's oldest black holes is giving astronomers some vital clues for how they came to be.
Two tight fasteners kept the majority of the Bennu asteroid sample from scientists since it returned to Earth in September. Now they've finally prised it open.
Just six hours into its maiden flight, Astrobotic Technology's Peregrine moon lander has experienced a technical fault that doomed the mission.
The tension, centered around a value for cosmic lumpiness known as S8, could join the Hubble tension in dethroning our best picture of how the universe evolved.
The first images from Euclid, planets, invisible rings, and the first hints of a neutron star’s wispy magnetic field. Here are the 8 space photos that melted our minds in 2023
For decades, measurements of the universe's expansion have suggested a disparity known as the Hubble tension, which threatens to break cosmology as we know it. Now, on the eve of its second anniversary, a new finding by the James Webb Space Telescope has only entrenched the mystery.
The oldest ever black holes, a preview of our solar system's gory demise, and a measurement of distant starlight that threatens to bring the standard of cosmology crashing down — here are the JWST's wildest discoveries of 2023.
University of Chicago astronomer Wendy Freedman tells us how she's searching for an answer to the Hubble tension — a discrepancy between measurements of our universe's expansion that could threaten the dominant model of how the universe has grown since the Big Bang.
Batteries could charge up by relying on a quantum effect known as indefinite causal order, whereby the laws of cause and effect are scrambled and power can move through the system quicker.
At the current emissions level, there is a 50% chance that global warming will exceed 1.5 degrees Celsius consistently in about seven years, new research suggests.
A weird phenomenon in which electricity flows like water was spotted in a nanowire made of "strange metal" — a bizarre metal phase that has stumped physicists for 40 years.
A sample from the asteroid Bennu, collected by the OSIRIS-REx mission, has arrived at London's Natural History Museum for analysis. Scientists are optimistic that it could contain the seeds of life.
The penguins accrue 11 hours of cumulative sleep a day from a bizarre adaptation that enables them to doze as they guard their nests.
Morton Allport earned his scientific reputation by grave robbing human remains and killing soon-to-be-extinct Tasmanian tigers before shipping them to Europe.
The hand was printed using a technique called slow-curing, which gives plastics more time to set and makes them more durable.
The Supergalactic Plane we are located in doesn't have many spiral galaxies like the Milky Way. Astronomers think they finally know why galaxies like ours are so rare.
China has denied that one of their rockets crashed into the moon's surface in 2022, leaving mysterious twin craters behind, but new research adds fresh evidence to the debate.
DeepMind's new machine learning algorithm takes less than a minute to make its forecasts and can run on a desktop. But it won't replace traditional forecasts anytime soon.
The newly discovered water mass, called the Atlantic Equatorial Water, stretches from Brazil to West Africa.
Scientists have spotted an aurora signal caused by electrons accelerating through a sunspot on our star's surface for the first time ever.
The magnolia wood LignoSat is an attempt to make space junk biodegradable. NASA and Japan's space agency (JAXA) could launch it as soon as 2024.
Climate change and rising sea levels could cause similar floods along the West Coast each year without El Niño by the 2030s, NASA warns.
The universe's early galaxies are way brighter than they should be. The James Webb Space Telescope's discovery of brightly glowing gas around 90% of primordial galaxies may explain why.
