Hubble is still going strong 35 years after it was launched into space. Celebrate its anniversary with some out-of-this-world images.
We summarize the week's scientific breakthroughs every Thursday.
The Curiosity rover identified hidden caches of the mineral siderite, which could help explain why Mars lost its habitable climate.
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.

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.
