Life on other planets could be far more widespread, study finds
(Phys.org) —Earth-sized planets can support life at least ten times further away from stars than previously thought, according to academics at the University of Aberdeen.
Newfound planet is Earth-mass but gassy
An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size ...
Pulsar in stellar triple system makes unique gravitational laboratory
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) have discovered a unique stellar system of two white dwarf stars and a superdense neutron star, all packed within a space smaller ...
New studies give strong boost to binary-star formation theory
(Phys.org) —Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery ...
Researchers use Hubble Telescope to reveal cloudy weather on alien world
Weather forecasters on exoplanet GJ 1214b would have an easy job. Today's forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds.
New technique measures mass of exoplanets
To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system. To determine if any of these far-off worlds are habitable requires knowing an exoplanet's ...
Powerful ancient explosions explain new class of supernovae
Astronomers affiliated with the Supernova Legacy Survey (SNLS) have discovered two of the brightest and most distant supernovae ever recorded, 10 billion light-years away and a hundred times more luminous ...
Scientists solve a decades-old mystery in the Earth's upper atmosphere
New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space enviro ...
Massive galaxy cluster verifies predictions of cosmological theory
(Phys.org) —By observing a high-speed component of a massive galaxy cluster, Caltech/JPL scientists and collaborators have detected for the first time in an individual object the kinetic Sunyaev-Zel'dovich ...
First noble gas molecules discovered in space
Noble gas molecules have been detected in space for the first time in the Crab Nebula, a supernova remnant, by astronomers at UCL.
Hubble discovers water vapor venting from Jupiter's moon Europa
The NASA/ESA Hubble Space Telescope has discovered water vapour erupting from the frigid surface of Jupiter's moon Europa, in one or more localised plumes near its south pole.
NASA Mars spacecraft reveals a more dynamic red planet
(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
Astronomers solve temperature mystery of planetary atmosphere
(Phys.org) —An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, University of Washington astronomers have found, and knowing that ...
Ancient fresh water lake on Mars could have sustained life, Curiosity researchers show
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life, in research published today in the journal Science.
