The origins of Earth’s water is a complicated mystery that scientists have been untangling for decades. Life is impossible without water, so the origin of Earth’s life-giving water is a foundational question. As the power of our telescopes grows, researchers have made meaningful headway on the question.

Mars Has Bizarre “Swiss Cheese” Terrain. You can Thank Water, Carbon Dioxide and 500,000 years of Climate History for That
Seen from space, regions of Mars around the south pole have a bizarre, pitted “Swiss cheese” appearance. These formations come from alternating massive deposits of CO2 ice and water ice, similar to different layers of a cake. For decades, planetary scientists wondered how this formation was possible, as it was long believed that this layering would not be stable for long periods of time.
NASA's Ingenuity helicopter captures breathtaking shot of Martian sunset (photo)
NASA's Ingenuity Mars helicopter recently took to the skies for its 45th flight, traveling nearly one-third of a mile (0.5 kilometers) — and photographing a Red Planet sunset in the process.
Say goodbye to winter stars and watch the night sky transition to spring this month
The sky is in transition throughout March as we watch the glorious wintertime stars and bright constellations give way to the somewhat dimmer stars of spring.
Boom! Japanese astronomer catches meteorite smashing into the moon (video)
Japanese astronomer Daichi Fujii captured the telltale flash of a meteorite impacting the moon, causing a brief flash on our celestial neighbor's nightside.
SpaceX, NASA targeting March 14 for next cargo launch to space station

Hubble Space Telescope images increasingly affected by Starlink satellite streaks
Starlink satellite streaks have been found spoiling Hubble Space Telescope images, and the situation is only bound to get worse, a new study has revealed.
Astronauts Could Clear Lunar Dust Away with Nitrogen Spray
One of the last times we did an article about a technology that could remove lunar dust from clothing, we opened it with a famous meme line from Star Wars. That also means we should probably avoid subjecting everyone to it again here. Still, the fact that we’ve had an opportunity to use it more than twice recently proves that removing lunar dust is a problem that has attracted a lot of attention in recent years. Artemis, NASA’s program to go back to the Moon this decade, is the cause of a lot of that attention as there are plenty of problems still to overcome. Some of those might be solved by a technique developed by a team at Washington State University (WSU) that uses every child’s gas that allows them to pound nails in with bananas – liquid nitrogen.
Earth spouts 'biosignatures' into space, hinting that other life-bearing worlds may do the same
Forms of oxygen created by living organisms can be found in space around our planet, a new study has revealed, hinting at a potential new method for tracing life on exoplanets.
Galileo: no way without time
Europe’s Galileo is the world’s most precise satellite navigation system, providing metre-level accuracy and very precise timing to its four billion users. An essential ingredient to ensure this stays the case are the atomic clocks aboard each satellite, delivering pinpoint timekeeping that is maintained to a few billionths of a second. These clocks are called atomic because their ‘ticks’ come from ultra-rapid, ultra-stable oscillation of atoms between different energy states. Sustaining this performance demands, in turn, even more accurate clocks down on the ground to keep the satellites synchronised and ensure stability of time and positioning for users.
Inspiring mocktail menu served up by Space Juice winners
An impressive 70 mocktail recipes representing a wide range of flavours of ESA’s Jupiter Icy Moons Explorer (Juice) mission were submitted to the Agency’s #SpaceJuice competition in January.

A comet coming in 2024 could outshine the stars - if we're lucky
A comet recently discovered zooming through our solar system has the potential to be quite bright when it arrives late in 2024, but comets have let us down before.
Newly discovered asteroid the size of a swimming pool has a 1-in-600 chance of colliding with Earth, NASA says
The newly discovered asteroid 2023 DW could collide with Earth in February 2046, although the odds of an impact are low.
This Week's Sky at a Glance, March 10 – 19
Venus and Jupiter widen in twilight. Mars, Aldebaran, and Betelgeuse form a triangle of similar orange sparkles. And there's lots to explore with optical aid off the trailing foot of Gemini, including the Toes.

Want Artemis to Succeed? Virtual Reality Can Help
Artemis astronauts are returning to the Moon, and they’ll be following in Apollo’s footsteps when they go. But things are different this time. Not only is technology far more advanced, but so is the way we think about technology and how we design it.
NASA scientists push for a treaty to tackle risky 'space junk'
As humanity increasingly fills the space around Earth with satellites, scientists have urged for an international treaty that could tackle the orbital debris these operations generate.
