Giant cliffs that encircle Olympus Mons formed when lava flowing down the volcano encountered deep water.

Upgrades to Kennedy Ground Systems near completion for Artemis II.

Astronomers using data from NASA’s James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Jupiters moon Europa.

New research suggests the same conditions that created the cracks could have been favorable to the emergence of microscopic life. Scientists aren’t entirely sure how life began on Earth, but one prevailing theory posits that persistent cycles of wet and dry conditions on land helped assemble the

Astronomers recently announced that they had discovered 62 new moons around the ringed planet Saturn and more are being added to the list. So, how have they lain hidden for so long?

"Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrinos—tiny, ghostlike astronomical messengers. In an article to be published in the journal Science, the IceCube Collaboration, an international group of over 350 scientists, presents evidence of high-energy neutrino...

Expedition 69 crew members on the ISS marked a busy week with cleaning, maintenance, and experiments. Frank Rubio, Sergey Prokopyev, and Dmitri Petelin celebrated a year in space, while others contributed to diverse tasks and scientific investigations.

Scientists have discovered that cosmic structures grow slower than Einstein's Theory of General Relativity predicts, with dark energy playing a more dominant inhibitory role than previously thought. This finding may reshape our understanding of dark matter, dark energy, and fundamental cosmic theori

There's a lot of trash on the moon right now—including nearly 100 bags of human waste—and with countries around the globe traveling to the moon, there's going to be a lot more, both on the lunar surface and in Earth's orbit.

It's almost like a stellar toddler sometimes gets into a bad mood and takes it out on a nearby stress ball.

India has launched its Chandrayaan-3 mission, which aims to explore the south pole of the moon by rover, completing a scientific mission that was first attempted in 2019 but ended in catastrophic failure due to a software glitch...

"Sandwiched planet formation" may arise as the result of gas and dust being squeezed between large planets.

Observers described it as an almost demolition derby-like collision of stellar remnants and stars in the chaotic neighborhood of the galaxy's central supermassive black hole. The source of the GRB flash lay just 100 light-years away from the heart of the galaxy. It turned out to be in very close proximity to the central...

Lunar soil is rich with clues about our origin and future home in space. Scientists can’t wait to get their hands dirty.

When people first started exploring space in the 1960s, it cost upwards of $80,000 (adjusted for inflation) to put a single pound of payload into low-Earth orbit....

The European Space Agency's ambitious Euclid space telescope is on its way to decoding the secrets of dark matter and dark energy.

The Apollo 17 lunar lander base is creating small-scale moonquakes on a daily basis.

New Giant Planet Is Evidence of Possible Planetary Collisions A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash. TOI-1853b's mass is almost twice that of any other similar

Astronomers have found planets that are twice as wide as Jupiter and more than 10 times as heavy, but there's a limit to how big planets can get.

A Southwest Research Institute-led team has modeled the early impact history of Venus to explain how Earth's sister planet has maintained a youthful surface despite lacking plate tectonics. The team compared the early collision histories of the two bodies and determined that Venus likely experienced higher-speed, higher-energy...

A study published this week in an astronomical journal suggests our universe could be 26.7 billion years old, or about twice as old as we thought.

The cold and mysterious Oort cloud at the edge of our solar system may be hiding a rogue planet

An annular solar eclipse, also known as a “ring of fire” eclipse because of the way the sun and moon line up, will be visible in the US, Central America and South America on 14 October...

Triton orbits to the beat of its own drum.

A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...
