Follow the radio waves to exomoons, astrophysicists say
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists ...
Nullarbor meteorite likely fragment of unknown asteroid
The first meteorite ever located solely using data from specially-placed cameras has been found to be geologically unique, presenting questions of its origins.
Crater creator uses explosions to find the secrets of volcanoes
You can learn a lot about volcanoes by studying explosions. The more we can learn about their explosive behaviour, the more chance we have of saving lives when they suddenly erupt.
Looking for a 'superhabitable' world? Try Alpha Centauri B, paper says
The search for extraterrestrial life extends far beyond Earth's solar system, looking for planets or moons outside the "stellar habitable zone" that may have environments even more favorable to supporting ...
Geological exploration reveals Australian super volcano
A geological survey team says an ancient super volcano exuded more than 450 cubic kilometres of molten magma in a single eruption, over what are now Ngaanyatjarra tribal lands.

Vesta: Large impacts of asteroids may have transferred carbonaceous material to the protoplanet and inner solar system
The protoplanet Vesta has been witness to an eventful past: images taken by the framing camera onboard NASA's space probe Dawn show two enormous craters in the southern hemisphere. The images were obtained ...
Scale of volcanic eruptions appears to hinge on first 10 seconds of bubble growth in magma, study shows
Volcanic eruptions vary from common, small eruptions that have little impact on humans and the environment to rare, large-to-gigantic eruptions so massive they can threaten civilizations.
