NASA’s Perseverance Mars rover has made what could be its most astonishing discovery to date: possible signs of ancient life on the Red Planet.
The six-wheeled robotic explorer came across an intriguing, arrow-shaped rock dubbed “Cheyava Falls” that might harbor fossilized microbes from billions of years ago, when Mars was a watery world.
Perseverance on Sunday last week drilled into the enigmatic rock to collect a core sample, as it traversed Neretva Vallis, an ancient river valley. The samples carefully stowed beneath the rover’s belly are destined to eventually return to Earth, where they would undergo more comprehensive analysis.

“Cheyava Falls is the most puzzling, complex and potentially important rock yet investigated by Perseverance,” project scientist and California Institute of Technology professor Ken Farley said on Thursday.
Three compelling clues have scientists buzzing. White calcium sulfate veins run the length of the rock, a telltale sign that water once flowed through it.
Between the veins is a reddish middle area, teeming with organic compounds, as detected by the rover’s Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals instrument.
Tiny off-white splotches ringed with black, reminiscent of leopard spots, contain chemicals that suggest energy sources for ancient microbes, according to scans by the Planetary Instrument for X-ray Lithochemistry instrument.
“On Earth, these types of features in rocks are often associated with the fossilized record of microbes living in the subsurface,” said David Flannery, an astrobiologist and member of the Perseverance science team from the Queensland University of Technology in Brisbane, Australia.
The quest to confirm ancient Martian life is far from over. The real test would come when Perseverance’s precious rock samples are returned to Earth as part of the Mars Sample Return Program, a collaboration between NASA and the European Space Agency slated for the 2030s.
While there are alternative explanations for the findings that do not involve microbes, there is a tantalizing chance that Perseverance’s core sample might contain actual fossilized microbes — potentially making history as the first proof of life beyond Earth.
“We have zapped that rock with lasers and X-rays and imaged it literally day and night from just about every angle imaginable,” Farley said. “Scientifically, Perseverance has nothing more to give. To fully understand what really happened in that Martian river valley at Jezero Crater billions of years ago, we’d want to bring the Cheyava Falls sample back to Earth, so it can be studied with the powerful instruments available in laboratories.”
RARE EVENT: While some cultures have a negative view of eclipses, others see them as a chance to show how people can work together, a scientist said Stargazers across a swathe of the world marveled at a dramatic red “Blood Moon” during a rare total lunar eclipse in the early hours of yesterday morning. The celestial spectacle was visible in the Americas and Pacific and Atlantic oceans, as well as in the westernmost parts of Europe and Africa. The phenomenon happens when the sun, Earth and moon line up, causing our planet to cast a giant shadow across its satellite. But as the Earth’s shadow crept across the moon, it did not entirely blot out its white glow — instead the moon glowed a reddish color. This is because the
DEBT BREAK: Friedrich Merz has vowed to do ‘whatever it takes’ to free up more money for defense and infrastructure at a time of growing geopolitical uncertainty Germany’s likely next leader Friedrich Merz was set yesterday to defend his unprecedented plans to massively ramp up defense and infrastructure spending in the Bundestag as lawmakers begin debating the proposals. Merz unveiled the plans last week, vowing his center-right Christian Democratic Union (CDU)/Christian Social Union (CSU) bloc and the center-left Social Democratic Party (SPD) — in talks to form a coalition after last month’s elections — would quickly push them through before the end of the current legislature. Fraying Europe-US ties under US President Donald Trump have fueled calls for Germany, long dependent on the US security umbrella, to quickly
In front of a secluded temple in southwestern China, Duan Ruru skillfully executes a series of chops and strikes, practicing kung fu techniques she has spent a decade mastering. Chinese martial arts have long been considered a male-dominated sphere, but a cohort of Generation Z women like Duan is challenging that assumption and generating publicity for their particular school of kung fu. “Since I was little, I’ve had a love for martial arts... I thought that girls learning martial arts was super swaggy,” Duan, 23, said. The ancient Emei school where she trains in the mountains of China’s Sichuan Province
Former Philippine president Rodrigo Duterte on Friday failed to attend in person an initial hearing at the International Criminal Court (ICC) as he faces crimes against humanity charges over his deadly crackdown on narcotics. The 79-year-old, the first ex-Asian head of state charged by the ICC, followed by video during a short hearing to inform him of the crimes he is alleged to have committed, as well as his rights as a defendant. Sounding frail and wearing a blue suit and tie, he spoke briefly to confirm his name and date of birth. Presiding Judge Iulia Motoc allowed him to
