Potentially Alive 830-Million-Year-Old Organisms Found Trapped in Ancient Rock

An incredible discovery has just revealed a potential new source for understanding life on ancient Earth. A team of geologists has just discovered tiny remnants of prokaryotic and algal life – trapped inside crystals of halite dating back to 830 million years ago. Halite is sodium chloride, also known as rock salt, and the discovery … Read more

This Cosmic Timekeeping Method Proposes to Synchronize All Clocks on Earth

Modern technology pulses with a heartbeat measured in microseconds. From global positioning systems to communications networks, it’s vital every component falls into near-perfect synch. Based on standards determined by a specialized task group, signals sent through optic fiber or down from an orbiting satellite tends to ensure time-sensitive technology matches moments down to the nanosecond. … Read more

Astronauts Have Distinct Brain Changes Even Months After They Return to Earth

Flung into freefall for months on end, our bodies adjust in ways that makes for a long list of health concerns for space travelers. The latest evaluation of microgravity’s warping effect on our biology focuses on the spaces surrounding the blood vessels that weave through our brain, revealing concerning changes that remain with astronauts between … Read more

Untouched Moon Fragments Kept in Storage For 50 Years Are Finally Being Studied

When the Apollo 15 and 17 missions returned to Earth with pieces of the moon in 1971 and 1972, some of the samples were deliberately set aside for the future. Flash forward half a century and these samples are finally being studied. In 2019, shortly after an upcoming Artemis mission to the Moon was announcednine … Read more

The Universe Could Start Shrinking ‘Remarkably’ Soon, Scientists Say

After nearly 13.8 billion years of nonstop expansion, the Universe could soon grind to a standstill, then slowly start to contract, new research published in the journal Proceedings of the National Academy of Sciences suggests. In the new paper, three scientists attempt to model the nature of dark energy – a mysterious force that seems … Read more

What Is The Hottest Temperature in The Known Universe, And Could We Achieve It?

From what we know about our Universe, the coldest possible temperature is ‘absolute’ zero degrees Kelvin, or -273.15 degrees Celsius (-459.67 degrees Fahrenheit). But what about the hottest possible temperature? Physics is a little fuzzy on what the absolute hottest of hot looks like, but theoretically speaking, such a thing does – or at least, … Read more

This Giant Moon of Saturn Has Yet Another Strange Similarity to Earth

Compared to most places you might wander in the Solar System, Titan – the giant moon of Saturn – is in many ways strangely familiar to Earth. In fact, Titan is the only moon in the Solar System with a dense atmosphere, providing a number of quasi-Earth-like weather phenomena, such as methane rainfallwhich feeds rivers … Read more

The Largest Marsquakes to Date Have Been Detected in The ‘Shadow Zone’

One of the most intriguing features of March is the presence of quakes not unlike ones we get on Earth. Since the start of 2019, planetary scientists have been logging these ‘marsquakes’ with a seismometer built into the InSight lander. Now, they’ve detected activity that points to the two largest marsquakes ever put on record. … Read more

Time May Not Exist at All, According to Physics

Does time exist? The answer to this question may seem obvious: Of course it does! Just look at a calendar or a clock. But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously. How can that be, and what would it mean? It’ll take a … Read more

These Tiny Crystals Are ‘Time Capsules’ of Earth’s Early Plate Tectonic Activity

Tiny crystals of zircon dated to 3.8 billion years ago contain the earliest geochemical evidence yet for plate tectonic activity here on Earth. Isotopes and trace elements preserved in the crystals show evidence that they formed under subduction conditions – when the edge of one tectonic plate slips beneath the edge of the adjacent plate, … Read more
