NASA's Parker Solar Probe has successfully completed its second science-gathering flyby of the sun, the space agency announced earlier this week.

NASA's Perseverance rover has encountered another rock on Mars that has left scientists puzzled.

The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once thought.

Two nearby explosive massive star deaths, or supernovas, may have triggered mass extinction events in Earth's distant past, new research suggests.

The James Webb Space Telescope (JWST) has directly imaged four planets orbiting the host star HR 8799 about 130 light-years from Earth in the constellation Pegasus.

A rock on Mars that may hold clues about ancient microbial life on the Red Planet continues to puzzle scientists.

"From our perspective down in the trenches actually working for the government, it feels like the people up top just have no clue about anything."

"We were surprised that water could actually form so early on — even before the birth of the first galaxies."

After more than a week of delays, two new NASA missions have gotten the greenlight to head to space tonight (March 8).

This week, geologists announced they discovered the world's oldest known impact crater. It's in Western Australia's ancient Pilbara region.

Higher latitudes on the moon with slopes facing the poles "are not only scientifically interesting but also pose less technical challenges for exploration in comparison with regions closer to the poles of the moon."

India's Aditya-L1 spacecraft captured detailed observations of a powerful solar flare last year, helping scientists better understand our star's eruptions.

A modest NASA space telescope with grand ambitions will soon launch into an orbit around Earth. Here's why scientists are excited about it.

NASA's Europa Clipper will fly past Mars today to adjust its trajectory and position itself for a critical phase of its 1.8-billion-mile (2.9-billion-kilometer) trek to the Jupiter system.

"Everyone in the United States relies on NOAA in their daily lives whether they realize it or not, something that will come into focus for many in the weeks and months ahead."

Astronauts in isolated space habitats could benefit from the intentional fostering of diverse microbes from humanity's evolutionary past, a new study suggests.

Scientists aim to answer some of the most fundamental questions about the universe using NASA's newest space telescope, SPHEREx, which is set to launch March 4.

"Every centimeter of sea level rise exposes another 2 million people to annual flooding somewhere on our planet."

A mysterious flash of X-ray emission from outside the Milky Way has left astronomers puzzled.

After the space community braced for a brutal shake-up at NASA this week, a last-minute decision on Tuesday (Feb. 18) spared over 1,000 agency employees on probationary status from being dismissed.

Scientists suggest adding jumping exercises to astronauts' training regimens, to minimize the health effects of long space missions, such as moon and Mars trips.

Boeing notified employees it is planning to issue layoff notices "to align with revisions to the Artemis program and cost expectations."

A space-based telescope has captured new images of the sun that showcase one of our star's fiery outbursts — and Mercury is in the picture.

"I'll always remember the first time I saw those iridescent clouds and was sure at first it was some color artifact."

Solar scientists have found tiny, short-lived jets of energy on our sun to be the primary drivers of the solar wind, marking a step toward better understanding our sun's elusive behavior.
