There are literal oceans' worth of liquid water hiding out on Mars. There's just one big problem. That water is actually in Mars, at depths that are too far below the surface for us to access.



					
			

That's according to new analysis of seismic data collected by the  Mars InSight lander, for which huge reservoirs of liquid water are the best explanation. And, although that water is out of reach, it is an important piece of the strange puzzle of the aquatic history of our dry, desiccated, dusty neighbor.

Scientists Just Found Oceans of Liquid Water on Mars – But There's a Catch

There was once a magma-filled ocean on the south pole of the moon, scientists recently discovered after analyzing lunar soil.

You’re reading this because something catastrophic terminated the more than 150-million-year reign of the dinosaurs. What opened the doors for mammals to dominate Earth was likely an extraterrestrial object; probably an asteroid. Where that asteroid came from has not been entirely clear. But new research might have gotten a giant step closer to solving this mystery. According to a study published Thursday in the journal Science, the rogue space rock probably came from far beyond Jupiter, and was likely laced with traces from the stars that existed before the Sun.

Scientists Finally Know Where the Dinosaur-Killing Asteroid Came From — At Least They Think

A new study suggests that millions of tiny space rock fragments, which were ejected from the deliberate 2022 collision between the asteroid Dimorphos and NASA's DART spacecraft, may be on a collision course with Earth and Mars. While these fragments are probably harmless, they could trigger the first human-caused meteor shower.

Astronomers have confirmed the existence of exoplanets with extremely small orbits around their stars. But what about exoplanets that get close enough to be devoured by their star, and what if it's an Earth-sized exoplanet?. This is what a recent study posted to the arXiv preprint server and accepted to...

Good thing we found this Earth-sized planet now—it's about to be destroyed

He knew 'nuteeng' except how to make people laugh and be successful, despite enormous challenges in his life and career. He was an actor best known as Seargent Hans George Schultz on TV's long-running military comedy, Hogan's Heroes (CBS, 1965-1971). His name was John Banner, and he died from an abdominal hemorrhage on his 63rd birthday in 1973. This is his triumphant and tragic story.

When an asteroid hit the Gulf of Mexico 66 million years ago, Earth changed forever. The impact caused a mass extinction event, killing around 60 per cent of the planet’s species – including all of the non-avian dinosaurs. Now, new evidence suggests that the asteroid behind the destruction...

The asteroid that killed the dinosaurs had a very strange origin, scientists find

Scientists have discovered compelling evidence suggesting that Earth’s first rain fell as early as 4 billion years ago, much earlier than previously believed. Published in Nature Geoscience, the research reveals that the hydrological cycle—the process by which water moves between the atmosphere and the land—was active only 500 million years after Earth formed. By analyzing ancient zircon crystals from the Jack Hills in Australia, scientists detected unusually light oxygen isotopes within these minerals. These isotopes, typically associated with the interaction of water and rock deep below the Earth’s surface, indicate that meteoric water (water originating from precipitation) was present much earlier than once thought. This challenges the prevailing theory that Earth was completely covered by the ocean during this period and suggests that the planet may have had landmasses capable of supporting life much sooner.

Geophysicists have unveiled a discovery of monumental proportions beneath the surface of Mars: a colossal hidden ocean capable of sustaining life. This subterranean reservoir, unearthed through seismic data collected by NASA's InSight Lander, is of such staggering scale that it could engulf the entire planet under a mile of water.

In the hours before sunrise on Tuesday, Aug. 27, you can see a nice grouping of solar system objects. First, find the roughly 40-percent-illuminated Moon. The next brightest object, to the lower right of the Moon, will be Jupiter. Then look to the lower left of Jupiter for Mars. The Red Planet, glowing at magnitude 0.8, will be several times as bright as any of the stars around it.

In a major advancement for space exploration, scientists have developed a method to extract water from moon dust, potentially revolutionizing the future of lunar colonization. Researchers from the Chinese Academy of Sciences (CAS) and the Ningbo Institute of Materials Technology and Engineering have created a new process that could generate water directly on the Moon, significantly reducing the need for Earth-based resupply missions. This breakthrough could play a key role in establishing permanent human settlements on the lunar surface.
