NASA's ICON atmosphere-studying satellite, well into an extended mission in space, fell silent on Nov. 25. Troubleshooting is ongoing, but the spacecraft has not responded to calls from home.

A strange local dwarf galaxy was hidden from astronomers for years by the glare of a foreground star, earning the nickname 'Peekaboo.'

On Mars, dust devils can have both positive and negative impacts on robotic exploration on the planet.

48,000 academic workers across California are fighting for higher wages and workplace protections.

Scientists have tracked a high-energy blast of radiation back to the collision of two neutron stars and the kilonova explosion that resulted from the violent merger.

An image of planet Earth captured by the crew of the Apollo 17 mission, the final mission of the Apollo program, which took off to the moon 50 years ago today.

New research solves the puzzle of how amino acids formed within space rocks that bombarded Earth during the violent early epoch of the solar system.

Measurements taken at Earth's neighbors, Mars and Venus, show the battle between high-energy cosmic rays from beyond the solar system and the influence of the sun in the inner solar system.

Satellites keep watching as the Mauna Loa volcano on Hawaii's Big Island continues spewing geysers of boiling lava and plumes of volcanic ash over a week after it woke up from a 38-year sleep.

There simply isn't enough normal matter to account for the amount of gravitational force needed to hold the universe together, meaning dark matter must be prevalent.

Ground has finally been broken today at two sites in Africa and Australia that will host the Square Kilometer Array Observatory (SKAO), the largest radio telescope in the world.

A plume of searing hot rock as wide as the continental U.S. is rising up from near the core of Mars and might help explain recent volcanism and earthquakes seen at the Red Planet, scientists say.

The team behind NASA's Lucy asteroid mission is resuming work with the spacecraft to fully deploy and latch its second solar array after a recent successful Earth flyby.

Astronomers observed a major eruption from a volcanic comet flying through the solar system, likely spewing more than 1 million tons of debris into space.

A new image shows the exposed heart of a distant galaxy in stunning detail, demonstrating the promise of a recent addition to the Very Large Telescope.

Using data from the Hubble Space Telescope, astronomers have created a stunning image of a cosmic fireworks display resulting from the explosion of a massive star.
