How stellar death can lead to twin celestial jets
(Phys.org) —Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae – colorful, glowing clouds of dust and gas. In recent ...
'Oldest star' found from iron fingerprint (Update)
As the Big Bang's name suggests, the universe burst into formation from an immense explosion, creating a vast soup of particles. Gigantic clouds of primordial soup, made mainly of hydrogen and helium, eventually ...
Kepler finds a very wobbly planet
(Phys.org) —Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting ...
Solving a physics mystery: Those 'solitons' are really vortex rings
(Phys.org) —The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying ...
Solar wind and space dust create new source of water, laboratory study suggests
Water ice is the most abundant solid material in the universe. Much of it was created as the byproduct of star formation, but not all. John Bradley of Lawrence Livermore National Laboratory and his team may ...
Milky Way may have formed 'inside-out': Gaia provides new insight into Galactic evolution
A breakthrough using data from the Gaia-ESO project has provided evidence backing up theoretically predicted divisions in the chemical composition of the stars that make up the Milky Way's disc – the vast ...
Black hole that doesn't emit x-rays discovered near massive star
First planet found around solar twin in star cluster
Astronomers have used ESO's HARPS planet hunter in Chile, along with other telescopes around the world, to discover three planets orbiting stars in the cluster Messier 67. Although more than one thousand ...
Surprising new class of 'hypervelocity stars' discovered escaping the galaxy
An international team of astronomers has discovered a surprising new class of "hypervelocity stars" – solitary stars moving fast enough to escape the gravitational grasp of the Milky Way galaxy.
Hubble traces the halo of a galaxy more accurately than ever before
Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from ...
Fingerprinting the formation of giant planets
A team of Brazilian and American astronomers used CFHT observations of the system 16 Cygni to discover evidence of how giant planets like Jupiter form.
Perth's planet hunter helps discover unusual exoplanet
An amateur Perth astronomer is part of an international team which has discovered a new and unusual planet orbiting outside the solar system.
NASA mission to reap bonanza of earth-sized planets
Set to launch in 2017, NASA's Transiting Exoplanet Survey Satellite (TESS) will monitor more than half a million stars over its two-year mission, with a focus on the smallest, brightest stellar objects.
Silhouettes of early galaxies reveal few seeds for new stars
(Phys.org) —An international team of astronomers has discovered that gas around young galaxies is almost barren, devoid of the seeds from which new stars are thought to form – molecules of hydrogen.
