Research finds numerous unknown jets from young stars and planetary nebulae
For many years astronomers have known that young 'protostars' drive supersonic jets of gas from their north and south poles. However, this is the first time that so many of them have been detected at once.
Evidence of a local hot bubble carved by a supernova
I spent this past weekend backpacking in Rocky Mountain National Park, where although the snow-swept peaks and the dangerously close wildlife were staggering, the night sky stood in triumph. Without a fire, ...
Astronomers measure weight of galaxies, expansion of universe
Astronomers at the University of British Columbia have collaborated with international researchers to calculate the precise mass of the Milky Way and Andromeda galaxies, dispelling the notion that the two galaxies have similar ...
After early troubles, all go for Milky Way telescope
A billion-dollar telescope designed to provide the most detailed map yet of the Milky Way is ready to start work after teething problems, the European Space Agency (ESA) said on Tuesday.
Satellite galaxies put astronomers in a spin
An international team of researchers, led by astronomers at the Observatoire Astronomique de Strasbourg (CNRS/Université de Strasbourg), has studied 380 galaxies and shown that their small satellite galaxies almost always ...
Astrophysicists model the formation of the oldest-known star in our galaxy
A team of researchers led by Dr. Stefano Bovino at the Institute for Astrophysics Göttingen (IAG) has conducted high-resolution simulations investigating the formation of the oldest-known star in our 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 ...

The Sloan Digital Sky Survey expands its reach
The Sloan Digital Sky Survey (SDSS) has launched a major program of three new surveys, adding novel capabilities to expand its census of the Universe into regions it had been unable to explore before.
Charting the heavens like never before, via Sloan Digital Sky Survey
The next phase of a global drive to map the night sky will bring the cosmos into greater focus than at any in human history.
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 ...
Astrophysicist seeks life on planets outside our solar system
"I call it 'the awakening.' The whole world is waking up to the fact that we're getting close to finding other Earths and signs of life," says Sara Seager, an MIT astrophysicist who is working to find life ...
Supermassive black hole blows molecular gas out of a galaxy at 1 million kilometres per hour
(Phys.org)—New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way.
Are ultra-luminous galaxies colliding?
(Phys.org) —ltra-luminous infrared galaxies ((ULIRGs) are galaxies whose luminosity exceeds that of a trillion suns, By way of comparison, our Milky Way galaxy has a typical modest luminosity of only about ...
