A progressively drying climate punctuated by variable wetter episodes may have precipitated the transition from our hominin ancestors to anatomically modern humans, according to research…
Mercury is small, fast and close to the sun, making the rocky world challenging to visit. Only one probe has ever orbited the planet and…
By studying dust in the habitable zones of nearby stars, the HOSTS Survey — led by UA astronomers and performed with Arizona telescopes — is…
By combining two-fluid global hydrodynamics simulations with a radiative transfer code, astronomers from the University of Arizona track and investigate the observational signatures of super-Earths….
Astronomers from the University of Arizona report the first detection of diffuse hydrogen in a vast halo surrounding the Milky Way. Sometimes it takes a…
Astronomers use new craters on Mars to see beneath the dust blanket and determine the underlying rock compositions and textures. Mars is a dynamic planet….
NASA’s High Resolution Imaging Science Experiment (HiRISE) gets a closer look at impact ejecta on the surface of Mars. Impact ejecta is material that is…
Using direct imaging, a team of astronomers has discovered a young Jovian exoplanet within a triple-star system. If you thought Luke Skywalker’s home planet, Tatooine,…
Using the Hubble Space Telescope, a team of astronomers has measured the rotation rate of an extreme exoplanet by observing the varied brightness in its…
This new image from NASA’s Mars Reconnaissance Orbiter shows dark streaks on the walls of Garni Crater on Mars. Astronomers believe these recurring streaks are…
An newly published study form MIT reveals how bombardier beetles superheat liquid and expel it in an intense, pulsating jet as a defensive mechanism. Bombardier…
A newly published study details the discovery of the brightest quasar in the early universe, powered by the most massive black hole yet known at…
Using images NASA’s Voyager-2, astronomer Erich Karkoschka has uncovered features in Uranus’ atmosphere that reveal an unexpected, strange rotation pattern and point to the possible…
Astronomers from the University of Arizona have discovered two dust belts surrounded by a large dust halo around young star HD 95086, providing researchers with…
Using the FourStar imager at Las Campanas Observatory, scientists have discovered evidence of water ice clouds on a newly discovered brown dwarf WISE J085510.83-071442.5 (W0855)…
A team of researchers has discovered how to change the crystal structure of graphene, a finding that could lead to smaller and faster microprocessors. A…
An international team of astronomers has solved a decades old space mystery, revealing a new theory for how collapsed stars become polluted. Scientists from the…
A new 3D model provides new insight into the turbulent death throes of supernovas, showing a turbulent interior that spits out star remnants prior to…
