The James Webb Space Telescope just released its first-ever exoplanet image. Here’s what’s so exciting about it, and what we can stand to learn.
By tracking a meteorite found in Morocco back to its origin in an asteroid crater on Mars millions of years ago, scientists can learn more about how the planets formed.

There are many bodies in the solar system we can’t easily access. But observations of their winds and sediments reveal a surprising amount.

A glimpse of a distant Jupiter-sized exoplanet sheds light on how gas giants form.
Earth’s interior 80 million years ago with hot structures in yellow to red (darker is shallower) and cold structures in blue (darker is deeper).
Ancient blobs deep inside the Earth gather together and break apart like continents, according to new research.
Plus, a section of a rocket is about to crash on the Moon. What scientists hope to learn from it. Listen to The Conversation Weekly podcast.
All moons and planets are constantly under barrage from asteroids and comets.

Across the solar system, asteroids and comets crash into moons and planets every day. The rocket collision will provide researchers with important data on how these collisions work.

The Hayabusa2 mission brought a piece of asteroid Ryugu back to Earth, where it has helped scientists resolve a long-standing puzzle.
The mission is set to launch in March 2022. Here’s what you need to know.

As we await the launch of the James Webb Space telescope, it’s timely to look back on what previous generations of telescopes have shown us.

Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.
Tiny pieces of an asteroid have revealed an unlikely origin for much of the water in Earth’s oceans.

Volcanic Moon rocks collected by a Chinese probe last year are around 2 billion years old, a new analysis shows. That’s a billion years younger than those brought back by the Apollo and Luna missions.
The Binar-1 mission is the first in a series that will hopefully culminate in a mission to the Moon, with satellites developed using know-how gained from designing tough instruments for the WA outback.
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.
China has fast-tracked its way onto the red planet, almost matching NASA’s capability in a fraction of the time. Its Zhurong rover will become the first to measure Mars’s magnetic field.
You might think lots of meteorites ultimately come from comets. Turns out, you’d be wrong, according to a new study that tracked meteors hurtling through the sky to find out where they came from.

The hunt for the space rock involved a few bits of sheep poo before the real meteorite was found.
