NASA rover discovers liquid water 'ripples' carved into Mars rock — and it could rewrite the Red Planet's history
- Scientists have discovered evidence of liquid water exposed to the air in ancient, shallow lakes on Mars.
- The finding challenges the belief that all water on Mars was covered in ice.
- The discovery was made by NASA's Curiosity rover, which captured images of wave ripples on two separate lakebeds.
- The presence of these ripples suggests that liquid water once flowed on Mars' surface and potentially extended the possibility for microbial habitability.

New fish species named for Princess Mononoke
- Scientists have named a new fish species for the character San (also called Princess Mononoke) in the animated movie Princess Mononoke, thanks to their similarly painted cheeks.
- The new fish species was discovered in a seafood market in China and identified as a type of deepwater tilefish belonging to the Branchiostegidae family.
- The fish has distinctive red and white stripes on its cheeks, resembling the makeup worn by the character San, leading to its name Branchiostegus sanae.
- San is a beloved character in Studio Ghibli's Princess Mononoke, known for her role as a protector of the forest and defender of nature.

Researchers surprised to discover what’s inside the moon’s core
- Fifty years after the Apollo 11 lunar landing, researchers have found the Moon has a solid core akin to Earth's, shedding light on its composition and evolution.
- Published in Nature, the discovery clarifies the presence of iron-rich materials in the Moon's crust, vital for understanding its geological history.
- Studies have revealed the Moon features a solid inner core and a fluid outer core, aligning with theories that it possessed a magnetic field in the past.
- This breakthrough, confirming the Moon's solid core, concludes decades of speculation and showcases advancements in research.
- Identified 20 years ago, the Moon's fluid outer core now has a detected solid inner core of about 500 kilometers, constituting 15% of its total size.
- Evidence supports the theory of the Moon differentiating early in history, with heavy materials forming the core and lighter ones the crust.
- Researchers used lunar surface data and laser ranging techniques to ascertain the solid core's existence, aiding in understanding the Moon's evolution.
- Scientists also observed material movement in the mantle, explaining the presence of iron-rich elements on the lunar surface.
- These findings enhance our solar system's history comprehension and shed light on lunar magnetic field disappearance.
- The Earth and Moon differ in core size, composition, state, temperature, and magnetic field strength, reflecting their distinct evolutionary paths.

1 million 'interstellar objects' — each larger than the Statue of Liberty — may lurk in the outer solar system
- More than 1 million 'interstellar objects' the size of the Statue of Liberty could be drifting unseen in the outer solar system.
- Scientists have only detected two confirmed interstellar objects in the solar system: 'Oumuamua in 2017 and Comet Borisov in 2019.
- Based on simulations, it is predicted that there are currently around 1 million 'macroscopic objects' from Alpha Centauri in the solar system.
- These interstellar objects are likely residing in the Oort Cloud and are almost impossible to spot.

Rare lunar eclipse to be visible from UK next month – when and where to see the next ‘Blood Moon’
- The first ‘Blood Moon’ of the year will be visible next month in North and South America, Europe, including London.
- A 'Blood Moon' occurs during a lunar eclipse when sunlight passing through Earth's atmosphere projects colors like pale red or burnt orange onto the Moon.
- The upcoming lunar eclipse is expected to start as a penumbral eclipse before progressing through partial and full eclipse phases.
- The eclipse, on March 13 or 14 depending on location, will last about six hours with totality lasting just over an hour.
- People in North and South America will witness the entire eclipse, while Europe will observe the beginning phases, and Asia the end.
- Only one in 10 people globally will see the entire eclipse, with the UK only able to view the penumbral phase.
- The lunar eclipse will peak at 6:58 am on March 14 in London, causing the Moon to have set below the horizon by then.
- Residents in certain parts of Europe will witness totality, while the rest will see a partial eclipse before sunrise.
- Observers can view the 'Blood Moon' with the naked eye due to reduced glare from Earth's shadow, but telescopes can enhance the color changes.
- For those unable to view the eclipse in person, live streams from space agencies and observatories are available.
