Although more eroded and not as tall, the newly discovered volcano rivals the others in diameter. It’s about 450 km across. The volcano sits on the eastern edge of a broad rise called Tharsis, home to 3 other well-known giant volcanoes.
Astronomers have found water vapor around a young star within the constellation Taurus, 450 light-years away from Earth.
For a quiet, dusty lump of a planet we see today, Mars has had a surprisingly violent history, one that could reveal some clues about Earth.
If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.
An international team of researchers has gained new insights into the formation of diamond rain on icy planets such as Neptune and Uranus, using the X-ray laser European XFEL in Schenefeld.
ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever found in this part of the planet.
How long does planet formation take? Maybe not as long as we thought, according to new research.
Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour than typically thought.
When researchers reconstructed lava flows on Mars, they realized the red planet is a lot more active than they previously thought.
The picture, resembling a glowing blue marble rippling into a black ocean, was funneled through the telescope’s infrared filters to capture wavelengths future space travelers wouldn’t see with the naked eye.
The scientists made a startling observation when they observed that the atmosphere of Mars dramatically ballooned outwards because of a void created due to a powerful gust of solar wind.
Water from Earth's surface can find its way deep into the planet, and new research explains how it changes the outermost region of the metallic liquid core.
When future astronauts explore Mars's polar regions, they will see a green glow lighting up the night sky. For the first time, a visible nightglow has been detected in the martian atmosphere by ESA's ExoMars mission.
Researchers have made the first direct detection of atomic oxygen in the atmosphere of Venus. Some say it builds the case the planet was more hospitable in the past.
Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
