Perseverance took a selfie next to its biggest accomplishment yet – the two small drill holes where the rover took samples of Martian rocks.
Perseverance and its helicopter sidekick, Ingenuity, have been on Mars for nearly nine months. The duo have taken rock samples, performed first flights and taken images of the delta in Jezero Crater.

New research suggests that fire from the sky in the form of a small asteroid annihilated a city near the Dead Sea 3,600 years ago.
A previously unknown filtering process inside some volcanoes can cause magma to shoot out like champagne from a bottle - and perhaps even make it easier to forecast when a volcano is about to erupt.
One of the hand prints discovered in Tibet that is believed to have been made by children.
Prehistoric hand and footprints analysed by a team of researchers are an early example of art.
Ligeia Mare on Titan.
From the tallest cliff in the solar system to its largest impact basin, geological processes on other worlds are very similar to those on our own planet.
Greenland’s conditions were once similar to those of a greenhouse. Volcanoes swelled the land, constricted seaways and gigatonnes of greenhouse gases were released into the atmosphere.
Indigenous artists have been engraving rock shelters for millennia - long before the Kimberley’s celebrated rock art paintings. Now the rocks’ natural coatings are yielding clues to the engravings’ creation.
An irregular cluster of fossil spores. (Scale 10 micrometres.)
When plants started growing on land, they changed the world. Ancient fossil spores hint at how and when they did it.
A mythical creature born of a misinterpreted fossil?

People tell tales to explain what they see – centuries later, scientists try to map handed-down myths onto real geological events.
Scientists have been studying lunar samples brought back from Apollo missions to understand the geologic history of the Moon.
Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.

Earth scientists are on the skilled occupation list for immigration even as universities cut back in this area. The problem lies with a funding model that offers no incentive to lift graduate numbers.
Stunning mosaic of oxidised copper in the form of azurite (blue) and malachite (green) in a rock.
Using geology and AI, a virtual model of how the Earth’s tectonic plates have evolved can help reveal deposits of copper.
When borders reopen, take an Aussie road trip and explore the continent’s unique geology, from meteorites in the Nullarbor Plain to rock formations that are billions of years old.

New results show why and how water is disappearing from Mars atmosphere.
New research suggests that Venus’ crust is broken into large blocks – the dark reddish–purple areas – that are surrounded by belts of tectonic structures shown in lighter yellow–red.

Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.
Two new NASA missions hope to answer important questions about Venus’ past.
Two new NASA missions – VERITAS and DAVINCI+ – are headed to Venus. The missions will use radar and a probe to learn about Earth’s hard-to-study and potentially prophetic neighbor.
This isn’t a painting or a stained-glass window — it’s a microscope image of light shining through the Earth’s mantle.
I look at fragments of the Earth’s mantle under a microscope to learn how fast molten rock moves from deep in the Earth to the surface. This can help us prepare for future volcanic eruptions.
Evidence from the Pilbara region suggests Earth in its youth behaved very differently to how it does today, and had more water within it than previously thought.
Ga-Mohana Hill in South Africa’s Northern Cape province.
People were drawn to Ga-Mohana for many reasons. Surface water was likely among them.
Lightning on early Earth.
Lightning strikes may have helped spark life on Earth, and may be continuing to help life start on other Earth-like planets.
