‘Never quit the lunar quest’ was this moon mission’s motto.
Here’s its tragic tale

As scientists search for worlds that may be habitable for life,
they’ve discovered a type that is common in the universe — but
doesn’t exist in our own solar system.
These enigmatic planets are called sub-Neptunes, which are larger than
Earth but smaller than Neptune.
An April study catapulted one such world, named K2-18b, into the
spotlight. Astronomers at the University of Cambridge claimed they
detected molecules in the planet’s atmosphere that might be
biosignatures — markers of biological activity that could hint at
past or present life.
Now, other groups of astronomers have looked at the same data and
disagree with the findings, saying there is more to the story.
The twists and turns in the ongoing conversation around planet K2-18b
showcase why the search for evidence of .
Lunar update
Indeed, persistence is everything when it comes to space investigation.
“Never quit the lunar quest” was the motto underpinning a
high-stakes mission that aimed to touch down on the moon Thursday. But
Tokyo-based Ispace at the time it should have landed.
The Resilience spacecraft was Ispace’s second bid at a soft lunar
landing. The company’s previous try with the Hakuto-R lunar lander
crashed into the moon in April 2023.
“This is our second failure, and about these results, we have to
really take it seriously,” said Ispace CEO Takeshi Hakamada of the
nail-biting attempt. Ispace has its work cut out for it, but it isn’t
giving up.
A long time ago
New research combining artificial intelligence with radiocarbon dating
is changing the way scholars think about the Dead Sea Scrolls.
Bedouin shepherds first spotted the scrolls in 1947 within a cave in
the Judaean Desert. Archaeologists then recovered thousands of scroll
fragments, including the oldest copies of the Hebrew Bible, from 11
caves near the site of Khirbat Qumran.
“They completely changed the way we think about ancient Judaism and
early Christianity,” said lead study author Mladen Popović, a dean
at the University of Groningen in the Netherlands.
Scholars thought the roughly 1,000 manuscripts, written mostly on
parchment and papyrus, ranged from the third century BC to the second
century AD. But some of the scrolls, which serve as a crucial
intellectual time capsule, , the new analysis suggests.
Ocean secrets
A World War I-era submarine was lost at sea off California’s coast
nearly 108 years ago, killing 19 crew members. Now, researchers from
the Woods Hole Oceanographic Institution have captured
never-before-seen .
Curiosities
The plague pandemic known as the Black Death killed at least 25 million
people across medieval Europe over five years.
The culprit behind the disease is a bacterium called Yersinia pestis,
which has led to three major plague outbreaks since the first century
AD — and it still exists today.
How has the plague persisted for centuries? Changes to one gene in the
bacterium created new, less deadly strains that kept hosts alive longer
so it could keep spreading.
The weaker strains have since gone extinct, according to new research.
But the findings could yield key clues to help scientists manage the
current bacterium’s dominant lineage, which is .
Fantastic creatures
If you’ve ever walked through a fruit orchard, you might have been
steps away from a living tower of worms.
That’s what researchers from the Max Planck Institute of Animal
Behavior and the University of Konstanz in Germany found when they
inspected rotten pears and apples.
Hundreds of the microscopic worms, called nematodes, climbed on top of
one another to form structures 10 times their size — even making a
— leading scientists to question what’s driving the behavior.
“What we got was more than just some worms standing on top of each
other,” said senior study author Serena Ding, a Max Planck research
group leader of genes and behavior. “It’s a coordinated
superorganism, acting and moving as a whole.”
Discoveries
These stories will pique your curiosity:
— For over a century, astronomers thought the Milky Way and Andromeda
galaxies would collide in 4.5 billion years, but new telescope
observations may change that. However, sooner.
— Archaeologists who uncovered the remains of an ancient Mayan
complex in Guatemala named the site after that are believed to
represent an “ancestral couple,” according to the country’s
Ministry of Culture and Sport.
— A fossil of the earliest known bird that was kept in a private
collection for decades has provided scientists with “one ‘Wow!’
after another,” including the specimen, said Dr. Jingmai O’Connor,
associate curator of fossil reptiles at the Field Museum.
