This Microscopic Fungus Survived NASA’s Sterilization Protocols—and Is Potentially Hardy Enough to Contaminate Mars

The microbe was gathered from the agency’s clean rooms, where experts build spacecraft in carefully controlled environments. The findings reveal gaps in the agency’s procedures to prevent durable hitchhikers

Some scientists suspect that microorganisms can hop between planets by jumping aboard debris kicked up by asteroid strikes.

Could Life on Earth Have Descended From Microbes That Traveled From Mars Long Ago?

Scientists demonstrated that an Earthly extremophile might withstand being ejected from the Red Planet on debris spewed into space due to an asteroid strike

Europa, one of Jupiter's moons

Jupiter’s Moon Europa Is a Top Candidate for Hosting Alien Life. But It May Lack the Geologic Activity Needed to Birth Microbes

On Earth, deep-sea vents may have given rise to the planet’s first life. But nothing of the sort seems to be happening at the bottom of Europa’s ocean, a study suggests

How the Disappearance of Flight 19, a Navy Squadron Lost in 1945, Fueled the Legend of the Bermuda Triangle

Eighty years ago, five planes vanished during a training run off the Florida coast. A patrol plane sent to search for the men went missing, too, giving rise to a host of conspiracy theories

Researchers used more than 400 samples of materials, such as this carbon-rich substance, to train and test the new A.I. system. 

Cool Finds

A.I. Reveals Signs of Early Life in 3.3-Billion-Year-Old Rocks. Next, It Could Continue the Search in Space

The new approach looks at the distribution of molecular fragments in material, allowing for broad surveys in degraded specimens

The dwarf planet Ceres, the only dwarf planet in the main asteroid belt, might have once been hospitable for life, according to a recent study.

Did the Dwarf Planet Ceres Once Host Life? Astronomers Suggest Chemical Energy Could Have Fueled Microbes Long Ago

Though no direct evidence of life has been found, models suggest Ceres had hot water shooting into its underground oceans billions of years ago, offering potentially hospitable conditions

Chemical Hints on a Distant Planet Offer ‘Strongest Evidence Yet’ for Life Outside Our Solar System, Astronomers Say

The James Webb Space Telescope spotted possible signatures for life in an exoplanet’s atmosphere. Still, researchers caution it’s far too early to call the findings definitive

The three-foot-tall model has an aluminum skeleton covered in latex, foam, straw, acrylic paint and adhesive.

The Body Model Used During a Famous Scene in ‘E.T.’ Is Heading to Auction

Created by Italian special effects designer Carlo Rambaldi, the three-foot-tall prop can be seen in the film hiding among stuffed animals in 10-year-old Elliott’s closet

In 2013, the Curiosity rover drilled this hole, which measures about 0.6 inches wide and 2.6 inches deep, into martian rock. The sample is now thought to contain long-chain organic molecules.

Curiosity Rover Discovers Largest Organic Compounds Ever Found on Mars, a Possible Sign of Ancient Life

The molecules may be remnants of fatty acids, which form cell membranes in Earth’s organisms, though they might have formed through a non-biological process

Researchers used a miniaturized laser mass spectrometer to identify signs of fossils in a gypsum quarry in Algeria. They suggest the same tool could find early fossils on Mars.

Scientists Hope This Tool Could Identify Tiny Fossils on Mars, Revealing Hints to Potential Early Life on the Planet

If Mars ever hosted microorganisms in its bygone oceans, their fossils might still be preserved in minerals—and now, we have a new potential way to find them

Scientists suggest finding extraterrestial intelligence is more likely than thought, arguing that complex life is not a cosmic fluke.

Intelligent Life May Be More Likely to Exist on Other Planets Than Previously Thought, Scientists Say

Researchers present an alternative to the long-held “hard steps” theory to explain the evolution of complex life, suggesting it’s the natural outcome of a habitable environment rather than a lucky break

On September 4, 1967, six identical silver disks appeared at equidistant locations along a plumb-straight line that bisected southern England.

How British College Students Convinced Authorities That Flying Saucers Were Invading the U.K.

To raise awareness for a charity event, aspiring engineers planted six UFOs across southern England on a single day in 1967

A scan of a color copy of the original computer printout bearing the Wow! signal, taken several years after the signal's 1977 arrival.

Mysterious ‘Wow!’ Radio Signal Might Finally Have an Explanation—and No, It’s Not Aliens

The infamous signal recorded in 1977 might have been a laser-like beam of radiation from a hydrogen cloud energized by a powerful, magnetic star, preliminary research suggests

Officials still don't know where the six-foot-five structure came from.

Cool Finds

Mysterious Monolith Appears Outside of Las Vegas

The reflective metal structure was found on a hiking trail in the Desert National Wildlife Refuge

Europa’s icy surface hides an ocean of liquid water underneath, making it a prime target in the search for extraterrestrial life.

See the Messages NASA Will Send to Space on Its Upcoming Mission to Europa

A metal plate affixed to the Europa Clipper is engraved with a poem, tributes to scientists and waveforms representing the word “water” in 103 languages, among other drawings

The Department of Defense's All-domain Anomaly Resolution Office was created in 2022 to investigate reports of unidentified anomalous phenomena.

U.S. Has ‘No Evidence’ of Alien Technology, New Pentagon Report Finds

A review of government investigations into unidentified anomalous phenomena since 1945 found that “most sightings were ordinary objects and phenomena and the result of misidentification”

Saturn's moon Mimas has a giant impact crater, named Hershel, that stretches across a third of its surface and makes it resemble the "Death Star" from Star Wars.

An Icy Moon of Saturn May Be Hiding a Vast Ocean Under Its Crust, Surprising Astronomers

Researchers suggest a global ocean lies 15 miles beneath the surface of Saturn’s “Death Star” moon, Mimas—a shocking discovery that could redefine what a habitable world looks like

Many reports of Unidentified Anomalous Phenomena (UAP) are later discovered to be some type of balloon.

NASA Report Finds No Evidence of Extraterrestrial Origin for UFO Sightings

However, no explanation can be ruled out, per the agency, which also appointed its first director of research into the subject

One of the two specimens presented to Mexico's Congress, photographed during a press conference of Mexican journalist and self-proclaimed UFO expert Jaime Maussan, in Mexico City on September 13, 2023.

Self-described UFO expert Jaime Maussan, whose claims of extraterrestrials have been debunked in the past, said the specimens were “non-human”
