Io's Odd Volcanoes --Some Reaching Up 250 Miles
Jupiter's moon, Io, is the volcanic epicenter of the Solar System, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high: its volcanism is so extensive that it gets completely resurfaced about once every million years or...
Prevailing Extraterrestrial Theory of Dinosaur Extinction Challenged --Dartmouth Scientists
In a geological moment about 66 million years ago, something killed off almost all the dinosaurs and some 70 percent of all other species living on Earth. Only those dinosaurs related to birds appear to have survived. Most scientists agree...
"Extraterrestrial Phosphorus Triggered Origin of Life" --The Key Element in Our DNA
While it is generally accepted that some important ingredients for life came from meteorites bombarding the early Earth, scientists have not been able to explain how that inanimate rock transformed into the building blocks of life. A new study from...
Earth-Like Planets in Universe Now Estimated at 100 Billion --("Paging Dr. Fermi!")
Researchers at The University of Auckland have proposed a new method for finding Earth-like planets and they anticipate that the number will be in the order of 100 billion using gravitational microlensing, currently used by a Japan-New Zealand collaboration called...
NASA to Livestream 'Dark-Matter' Discovery Today
NASA will unveil the first discoveries from a powerful $2 billion particle physics experiment on the International Space Station in what could be a major vindication for the science tool, which almost never made it into space. NASA will hold...
Image of the Day: The Milky Way's Brilliant Dwarf Neighbor
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern...
The Galaxy's 2010 April Fool's Uproar --"'Man from the Future' Arrested At CERN's LHC Escaped Custody -True Identity Discovered"
In 2010, The Daily Galaxy did a post about a would-be saboteur arrested on April 1 at the Large Hadron Collider in Switzerland who made the bizarre claim that he was from the future. Many of the Galaxy's readers and...
Comment of the Day: "Are We Living in a Simulated Universe?"
"The fact that heavy elements were plentiful only 5 billion years after the big bang is a very good sign about the possibility of alien-life evolving in the very earlier universe. But of course that then leads to the annoying...
Puzzle of Spiral Galaxies Solved --"Self-perpetuating, Persistent, and Surprisingly Long Lived”
Some 15 percent of all galaxies in the visible Universe are spirals. The great fog-like clouds of stars, the oldest and largest galaxies in the Universe are ellipticals. Becasue ellipticals also include many of the smallest galaxies, they are the...
Movement of Galaxy Clusters Opens New Window on the Universe --May Unlock Key to Dark Energy
A large research team from two major astronomy surveys reports that scientists detected the movement of distant galaxy clusters via the kinematic Sunyaev-Zel’dovich (kSZ) effect, which has never before been seen. First proposed in 1972 by Russian physicists Rashid Sunyaev...
Image of the Day: New Views of a Spectacular Star Death
In February of 1987 astronomers observing the Large Magellanic Cloud, a nearby dwarf galaxy, noticed the sudden appearance of what looked like a new star. In fact they weren't watching the beginnings of a star but the end of one...
Image of the Day: A Strange Spiral Star 14-Billion Miles Wide
The discovery of a star with spiral arms in 2011 startled researchers using the Subaru telescope in Hawaii. The star, SAO 206462, is more than four hundred light years from Earth in the constellation Lupus, the wolf. Two spiral arms...
EcoAlert: "Massive Greening in the Arctic Over Next Few Decades"
New research out of Woods Hole predicts that rising temperatures will lead to a massive “greening,” or increase in plant cover, in the Arctic. In a paper published on March 31 in Nature Climate Change, scientists reveal new models projecting...
A Supernova Epicenter and "Gravity Engine" 100-Million Times Mass of the Sun
The NASA/ESA Hubble Space Telescope captured a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim...
Shape-Shifting Neutrinos --Another Challenge to the Prevailing Standard Model of Physics
Among the unsolved mysteries confronting 21st century physics from gravitational waves to dark energy, neutrinos -the "ghosts of the cosmos"- are near the top of the list. These awesomely low-mass subatomic particles, less than a millionth of the mass of...
The Daily Poll --"Is the Evolution of Life Coded Into the Physical Laws of the Universe?"
In 1995, the astronomer Edward Harrison suggested in an audacious paper published in Great Britain in the "Quarterly Journal of the Royal Astronomical Society" that our universe was created by life forms possessing superior intellingence existing in another physical universe...
An 'Infinity of Dwarfs' --A Visible Universe of 7 Trillion Dwarf Galaxies
Astronomers estimate that there are between 100 billion and 200 billion galaxies in the known universe. A single galaxy such as the Milky Way contain upwards of 200 billion normal stars. About 75 percent of of all stars in the...

Is There a Neanderthal in Your DNA? --New Study Says "There Might Be"
Researchers believe they have pinpointed the skeletal remains of the first known human-Neanderthal hybrid, according to a study published Wednesday in the peer reviewed scientific journal PLoS ONE. The finding comes from northern Italy, where some 40,000 years ago scientists...
Could Titan's Hydrocarbon Chemistry Have Crossed the Chasm to Life? (Today's Most Popular)
Saturn’s giant moon Titan has water frozen as hard as granite and Great Lakes-sized bodies of fed by a complete liquid cycle, much like the hydrological cycle on Earth, but made up of methane and ethane rather than water. Methane...
