A team of South Korean scientists has uncovered new evidence that could help explain how Earth’s atmosphere became rich in oxygen, one of the most transformative events in the planet’s history. Researchers from the Korea Institute of Geoscience and Mineral Resources (KIGAM) report the finding of stromatolites, layered structures formed by microbial communities, within the Hapcheon impact crater on the Korean Peninsula. While the Hapcheon crater is only about 40,000 years old, it shows how stromatolites got a boost from the heat in impact crater hydrothermal systems.

Could the "Great Silence" be the result of extraterrestrial civilizations dying out before they can make contact, or will they evolve to the point where communication with them is no longer possible?

It’s 2035 and NASA’s Dragonfly quadcopter has been “hopping” around the surface of Saturn’s largest moon Titan for just over a year taking images, scanning pebbles, drilling holes, and analyzing surface material for potential signs of life. You’re at NASA JPL and just moved to Blue Team (12am-8am) from Red Team (4pm-12am), so you’re hyped up on coffee, Red Bull, and will power. It’s 3:30am, you’ve been analyzing data since you clocked in, and you keep discarding what you’ve been told looks like positive signs of life but is more commonly known as false positives. In the meantime, some microbes on Titan that got scanned by Dragonfly keep posing in front of its main camera with signs saying, “We’re here!”

Spiral galaxy NGC 3169 looks to be unraveling like a ball of cosmic

This teensy creature was discovered along a deep-sea mountain

Over the course of 13 expeditions and other efforts between mid-2025 and mid-2026, scientists found hundreds of previously undiscovered creatures living under the waves

Across the center of this spiral galaxy is a

Our universe appears flat—but this observation still leaves plenty of options for its true shape. In fact, our cosmos could resemble a donut

You’re on the fourth human mission to Mars, and you’ve been tasked with establishing the first self-sustaining food crop on a Martian settlement. You’re nervous because you’re using a new type of fungi called beneficial fungi, which you’re told will help enhance Martian regolith, enabling it to be used for growing crops. You were privately told that doing this will not only get a high school named after you, but you will successfully feed future settlers without the need to bring food from Earth. But you really only care about having your name on a high school.

SpaceX's next-generation Starship V3 rocket got off to a glorious start for its first test flight, and although not all of its engines fired fully according to plan, SpaceX CEO Elon Musk said the mission "scored a goal for humanity."

No dust, no way to cool a collapsing gas cloud. No way to cool it, no stars. No dust, no first rung on the ladder from grain to pebble to planet. The substance I spent two articles complaining about turns out to be the substance that makes me possible.

Friday’s test flight marks a major milestone for SpaceX as the company gears up to go public and to participate in NASA’s Artemis III mission in 2027
