Archaean

If true, it could expand how we search for life elsewhere in the universe.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

On a young Earth, giant meteors might have been a harbinger of life, not death.

A new study suggests that ancient L-form bacteria could explain the strange microfossils found in some of the world's oldest rocks.

NASA's TESS telescope has discovered a system of six young exoplanets that race around a newborn star, offering a snapshot of what our solar system looked...

The Argyle mine in the Kimberley region of Western Australia is the world's largest source of natural diamonds.

Is there more to life than oxygen? Today's authors look into what other molecules could be observed with extremely large ground-based telescopes in the search for life on exoplanets!

Current research indicates that (sub)surface ocean worlds essentially devoid of subaerial landmasses (e.g., continents) are common in the Milky Way and that these worlds could host habitable conditions, thence raising the possibility that life and technological intelligence (TI) may arise in such aquatic settings. It is known, however, that TI on Earth (i.e., humans) arose on land. Motivated by these…

The humble stromatolite fossils may not look as cool as dinosaurs, but they were the rulers of ancient Earth — and none of us would be here without them.

Need to estimate, from trillions of miles away, how likely another world is to host life? There's a flowchart for that.

Poor old Venera 9, the Soviet Union's Venus lander, separated from its orbiter and made a hot, violent descent through the dense Venusian atmosphere on October 22, 1975, landing hard on a circular shield designed to crumple and absorb the impact. It only survived the intense surface conditions for 53 minutes, transmitting data regarding clouds, light irradiance, temperature and atmospheric chemistry, as well as the…

We got hands-on with an early chunk of Rainbow Six: Extraction, a Siege spin-off that's a tactical triumph of a zombie-slaying experience.

The planet's first photosynthesizers dined on green light

The Extremely Large Telescope will revolutionize our view of the cosmos when it sees first light in Chile in 2028. In fact, it could detect hints of alien life around our closest neighboring star system in its first night of operations, new simulations suggest.

Biology may have begun with a bang.

Long known as a messenger within cells, RNA is increasingly seen as life's molecular communication system—even between organisms widely separated by evolution.

Huge iron ore deposits in Western Australia's Hamersley Province formed when major tectonic events led to the breakup of supercontinent Columbia and to the amalgamation of Australia.

The search for extrasolar planets is currently undergoing a seismic shift. With the deployment of the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), scientists discovered thousands of exoplanets, most of which were detected and confirmed using indirect methods.

A chunk of Western Australia once raced across the globe at over 64 cm a year.

United States District Judge Lewis Kaplan has set a trial date in writer E. Jean Carroll's rape case against former President Donald Trump.Journalist Adam Klasfeld first reported that Kaplan had accepted Carroll's proposed trial date of April 10, 2023.Carroll revealed in 2019 that she had allegedly ...
