Habitable zone super Jupiter-sized exoplanet found in Milky Way bulge
Starless cloud cores reveal why some stars are bigger than others
Massive stars – those at least 8 times the mass of our Sun – present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller?
Researchers image the Milky Way's magnetic fingerprint
(Phys.org) —Our Galaxy's magnetic field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarised' light emitted by interstellar dust ...
Smallest known galaxy with a supermassive black hole found
A University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object. ...
Researchers find new relationship involving black holes in galaxies with small bulges
Research at Swinburne University of Technology has shown that it is possible to predict the masses of black holes in galaxies for which it was previously thought not possible.
Chandra helps confirm evidence of jet in Milky Way's black hole
(Phys.org) —Astronomers have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles. Finally they ...
Astronomers complete cosmic dust census
An international team of astronomers has completed a benchmark study of more than 300 galaxies, producing the largest census of dust in the local Universe, the Herschel Reference Survey. Led by Dr Luca Cortese ...
Astronomers breathe new life into venerable instrument
How do astronomers determine the shapes of objects that are too far away to photograph? One method is by using spectropolarimetry, an observational technique that measures the way light waves align after ...
Stars' clockwork motion captured in nearby galaxy
(Phys.org) —Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars.
Fat or flat: Getting galaxies into shape
Australian astronomers have discovered what makes some spiral galaxies fat and bulging while others are flat discs—and it's all about how fast they spin.
Team discovers two stars most distant ever observed in the Milky Way
The distant outskirts of the Milky Way harbor valuable clues for understanding the formation and evolution of our Galaxy. Yet, due to overwhelming distances and an extremely sparse population of stars, many ...
Astronomers spot faraway Uranus-like planet
Our view of other solar systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus.
Stars born in filaments tend to outweigh stars formed in the field
The mass distribution of stars is called the initial mass function, or IMF for short, and it characterizes the properties not only of our Milky Way, but of all the other galaxies we observe as well. But is ...
New survey begins mapping nearby galaxies
A new survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) has been launched that will greatly expand our understanding of galaxies, including the Milky Way, by charting the internal ...
