Colossal hydrogen bridge between galaxies could be fuel line for new stars
Researchers studying a filament of hydrogen between the Andromeda and Triangulum galaxies found rotating clumps of gas the size of dwarf galaxies. But questions remain.
-
Life after Higgs boson: What's next for the world's largest atom smasher?
It's a Higgs boson!! Now what? After confirming that the particle discovered last July really is a Higgs boson, the Large Hadron Collider is ready to look for other universes, figure out dark matter, recreate the Big Bang, or find something totally unexpected.
-
Milky Way's neighbor galaxy closer than thought
Astronomers in Chile announced that they are able to measure more accurately the distance to Large Magellanic Cloud, a galaxy adjacent to the Milky Way.
-
Primordial galaxy spotted, sheds light on early universe
Scientists were able to see the ancient galaxy because gravity from a massive galaxy cluster situated between it and Hubble acted as a lens, bending the light from the 'incredibly faint' galaxy.
-
Distant galaxy helped tidy up early universe, scientists say
Using data from space telescopes, scientists say they have located a galaxy formed more than 13 billion years ago when the universe was young and still permeated with a fog of hydrogen gas.
-
Cosmic lens reveals galaxy from the dawn of time
This distant, ancient galaxy may have once helped clear out the murky fog that once filled the early universe, scientists added.
-
Dark energy: Can $40m camera help solve its mystery? (+video)
The Dark Energy Camera, on a telescope high in the Chilean desert, is expected to capture 300 million galaxies, 100,000 galaxy clusters, and some 4,000 supernovae over the next five years.
-
Dark Energy Camera whirs to life, begins snapping deep-space photos (+video)
Scientists think dark energy makes up 74 percent of the universe, yet they have very little idea what it is.
-
Where does dark energy come from? New simulation could reveal origins.
Using the world's third-fastest computer, researchers seek to explain dark energy by running a simulation of the universe, from the Big Bang to the present day.
-
Scientists probe mysterious origins of humongous star explosions
Super-luminous supernovas, the biggest known explosions in space, remain shrouded in mystery. But scientists are beginning to understand their origins, which could help explain the creation of heavy elements in the early universe.
-
Astronomers release biggest ever 3-D map of the universe (+video)
Using data from the Sloan Digital Sky Survey III, the 3-D map contains more than a million galaxies.
-
Ancient spiral galaxy baffles astronomers (+video)
Using data from the Hubble telescope, scientists have found the oldest spiral galaxy in the universe, a galaxy that, according to current models, isn't supposed to exist.
-
Astronomers discover oldest spiral galaxy in the universe (+video)
The discovery with Hubble Space Telescope of a spiral galaxy, long before other galaxies are known to have formed, surprised scientists
-
Hubble telescope reveals mysterious 'ghost galaxies' of ancient universe
Formed some 13 billion years ago, three bizarre galaxies captured by the Hubble telescope are thought to be 'fossils' of the early universe
-
New European space telescope to sniff out dark matter
Scheduled to launch in 2019, the European Space Agency's Euclid space telescope will attempt to detect the dark matter and dark energy that accounts for most of the universe.
-
Could the Higgs boson teach us anything about dark matter? (+video)
If the existence of the Higgs boson is confirmed, it would complete the Standard Model of particle physics. But does that bring us any closer to understanding a mysterious substance thought to account for more than four fifths of the total mass of the universe?
-
Giant filament of dark matter connects galaxy clusters, say astronomers (+video)
For the first time, astronomers say they spotted a string of dark matter via gravitational lensing.
-
Will scientists announce discovery of Higgs boson? Buzz is building. (+video)
Chatter suggesting that the Higgs boson – the theoretical source of all mass – has been found is mounting. But if that's true, the 'God particle' will raise questions of its own.
-
Astronomers find humongous galaxy cluster, thanks to gravitational lensing
Using NASA's Huble Space Telescope, astronomers have detected a huge cluster of galaxies some 10 billion light-years away. The cluster is so massive that it distorts light that passes near it.
-
Amazing photo shows 'swarm' of stars (+video)
Tens of thousands of stars can be seen clustered together in a new image.
-
Attempting to recreate Big Bang conditions, CERN scientists break energy record
Scientists at CERN may be getting closer to Higgs boson the particle that could help explain the birth of the universe billions of years ago.
-
Survey: Galaxies become cannibals as teens
Billions of years after the Big Bang, adolescent galaxies seem to be snacking on smaller galaxies.
-
Galactic collision creates mysterious 'dark core'
Images captured by the Hubble telescope reveal a mysterious clump of dark matter thought to be left behind after a massive galactic collision. But this dark matter isn't behaving in the way scientists expect dark matter to behave.
-
Faster-than-light neutrinos? Why nobody is surprised it might be an error.
Last year, European particle physicists observed neutrinos apparently traveling faster than the speed of light. But now it seems that it was a bad measurement, which is no surprise to the physics community.
-
Will 2012 be the year scientists find the 'God Particle'? (+video)
Researchers at CERN are cranking up the power on their Large Hadron Collider, in a last-ditch attempt to uncover the Higgs Boson, the so-called God Particle thought to be responsible for giving matter the property of mass. This will be their last chance to find the elusive particle before the particle-smasher is shut down for an upgrade.
