In the search for life on other planets, the presence of oxygen in a planet’s atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which a lifeless rocky planet around a sun-like star could evolve to have oxygen in its atmosphere.

The new findings, published April 13 in AGU Advances, highlight the need for next-generation telescopes that are capable of characte...

Jupiter’s polar cap is threaded in part with closed magnetic field lines rather than entirely with open magnetic field lines, new research finds. Auroral displays continue to intrigue scientists, whether the bright lights shine over Earth or over another planet. The lights hold clues to the makeup of a planet’s magnetic field and how that field operates.

New research about Jupiter proves that point — and adds to the intrigue.

A research team has discovered that the Martian climate alternated between dry and wetter periods, before drying up completely about 3 billion years ago. The Perseverance rover has just landed on Mars. Meanwhile, its precursor Curiosity continues to explore the base of Mount Sharp (officially Aeolis Mons), a mountain several kilometres high at the centre of the Gale crater...

Astronomers have found evidence that the first exoplanet that was identified transiting its star could have migrated to a close orbit with its star from its original birthplace further away.

Analysis of the planet’s atmosphere by a team including University of Warwick scientists has identified the chemical fingerprint of a planet that formed much further away from its sun than it currently resides...
