A NASA rover finally found Mars’ missing carbon
The Curiosity rover identified hidden caches of the mineral siderite, which could help explain why Mars lost its habitable climate.
- Astronomy
Yes, there really is a black hole on the loose in Sagittarius
Astronomers now agree: They’ve spotted the first isolated stellar-mass black hole ever seen.
- Planetary Science
Check out some of the weird rocks that have turned up on Mars
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.

Fermenting miso in orbit reveals how space can affect a food’s taste
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.
- Astronomy
A nebula’s X-ray glow may come from a destroyed giant planet
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.
- Space
‘Star Wars’ holds clues to making speedier spacecraft in the real world
Controlled fusion, solar sails or ion engines could someday help spaceships travel between star systems.
- Space
JWST spots the earliest sign yet of a distant galaxy reshaping its cosmic environs
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.
- Cosmology
A map of 14 million galaxies and quasars deepens a dark energy mystery
The DESI experiment shocked cosmologists with a hint that dark energy varies over time. Now, with more data, the conclusions hold up.
- Space
The nearest single star to Earth has four small planets
Last year, astronomers announced that a planet orbits Barnard’s star. Now, researchers have confirmed the existence of three more.
- Space
Two astronauts stuck in space for 9 months have returned to Earth
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.
- Cosmology
New baby pictures of the universe deepen a cosmic mystery
Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.
- Space
The Blue Ghost lander just witnessed a lunar eclipse — from the moon
The privately-owned lander turned its cameras toward Earth as our planet cast its shadow over the moon. It’s not the first spacecraft to do so.
