Big asteroid will eclipse bright star Thursday
Skywatchers, get ready to see a rare vanishing act—and don't blink.
Every red dwarf star has at least one planet
Three new planets classified as habitable-zone super-Earths are amongst eight new planets discovered orbiting nearby red dwarf stars by an international team of astronomers from the UK and Chile.
Pushy black holes stop elliptical galaxies from forming stars
Contradicting past theories, cold gas has been found in abundance in some elliptical galaxies—showing that there must be some other explanation why these types of galaxies don't form new stars. Astronomers ...
The oldest star in the universe? Maybe, maybe not
There is a myth that goldfish have a three-second memory, and I sometimes wonder if the same is true about the part of the human mind that deals with science in the news.
Image: Hubble looks in on a nursery for unruly young stars
(Phys.org) —This striking new image, captured by the NASA/ESA Hubble Space Telescope, reveals a star in the process of forming within the Chameleon cloud. This young star is throwing off narrow streams ...
Universe's early galaxies grew massive through collisions
It has long puzzled scientists that there were enormously massive galaxies that were already old and no longer forming new stars in the very early universe, approx. 3 billion years after the Big Bang. Now ...
Molecular clouds in the whirlpool galaxy appear to be embedded in fog
(Phys.org) —A multi-year study of the Whirlpool galaxy (M51) has changed our understanding of giant molecular clouds, in which stars are born. The new study, which mapped 1,500 such clouds, shows that, ...
Magnetic field may shape 'blooming' star
(Phys.org) —An old star, IRAS 15445-5449, has begun to push out a jet of charged particles that glow with radio waves.
Pulsating dust cloud dynamics modeled
The birth of stars is an event that eludes intuitive understanding. It is the collapse of dense molecular clouds under their own weight that offers the best sites of star formation. Now, Pralay Kumar Karmakar from the Department ...
(Phys.org) —This new view of the Orion A star-formation cloud from ESA's Herschel space observatory shows the turbulent region of space that hugs the famous Orion Nebula.
New theory points to 'zombie vortices' as key step in star formation
(Phys.org) —A new theory by fluid dynamics experts at the University of California, Berkeley, shows how "zombie vortices" help lead to the birth of a new star.
The odd couple: Two very different gas clouds in the galaxy next door (w/ Video)
(Phys.org) —ESO's Very Large Telescope has captured an intriguing star-forming region in the Large Magellanic Cloud—one of the Milky Way's satellite galaxies. This sharp image reveals two distinctive ...
When galaxies switch off: Hubble's COSMOS survey solves 'quenched' galaxy mystery
Some galaxies hit a point in their lives when their star formation is snuffed out, and they become "quenched". Quenched galaxies in the distant past appear to be much smaller than the quenched galaxies in ...
Hubble eyes a mysterious old spiral
This striking cosmic whirl is the center of galaxy NGC 524, as seen with the NASA/ESA Hubble Space Telescope.
