We summarize the week's scientific breakthroughs every Thursday.
Astronomers now agree: They’ve spotted the first isolated stellar-mass black hole ever seen.
Some of the unusual rocks carry stories about water on Mars. One has hints of long-gone microbes. All tell of a dynamic, complex planet.
A miso test on the International Space Station shows fermenting food is not only possible in space, it adds nuttier notes to the Japanese condiment.
Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.
Controlled fusion, solar sails or ion engines could someday help spaceships travel between star systems.
The galaxy, called JADES-GS-z13-1, marks the earliest sign yet spotted of the era of cosmic reionization at 330 million years after the Big Bang.
The DESI experiment shocked cosmologists with a hint that dark energy varies over time. Now, with more data, the conclusions hold up.
Last year, astronomers announced that a planet orbits Barnard’s star. Now, researchers have confirmed the existence of three more.
Astronauts Suni Williams and Butch Wilmore’s extended stay in the International Space Station will add to what we know about how space affects health.
