Hubble Reveals Underground Ocean on Jupiter’s Moon Ganymede

Interior of Jupiter’s Largest Moon Ganymede

By watching the rocking motion of the two aurorae, astronomers have determined that a large amount of saltwater exists beneath Jupiter’s moon Ganymede. NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water […]

Saturn’s Moon Enceladus Exhibits Signs of Hydrothermal Activity

Data Suggest Saturn Moon's Ocean May Harbor Hydrothermal Activity

Using data from NASA’s Cassini spacecraft, two newly published studies reveal the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities. “These findings […]

New Strain of H1N1 in India Raises Concern

H1N1 Outbreak in India Raises Concern

New research from MIT finds evidence that a new strain of H1N1 may carry dangerous mutations. Since December, an outbreak of swine flu in India has killed more than 1,200 people, and a new MIT study suggests that the strain has acquired mutations that make it more dangerous than previously circulating strains of H1N1 influenza. […]

Survey of Carina Nebula Reveals Details of Star Formation

New Study Reveals Details of Star Formation

A newly published study about the Carina Nebula is helping astronomers better understand the processes that may have contributed to the formation of the sun 4.5 billion years ago. The Carina Nebula survey is published in the Astronomical Journal. “Most stars form in giant molecular clouds, regions where the density of matter is sufficient for […]

Hubble’s View of the Orion Nebula

Hubble Image of the Orion Nebula

First released in 2006, this popular image reveals Hubble’s sharpest view to date of the Orion Nebula. The image offers a peek inside a cavern of roiling dust and gas where thousands of stars are forming. The image, taken by the Advanced Camera for Surveys (ACS) aboard NASA/ESA Hubble Space Telescope, represents the sharpest view […]

Magnetospheric Multiscale Mission Set to Study Magnetic Reconnection Near Earth

An Enlil Model Shows How a CME Works

The MMS mission is set to explore the magnetic reconnection at the nose of the magnetosphere, providing the first ever three-dimensional view of this process as it is happening and unprecedented amounts of information to help scientists better understand what sets it off and what effects it causes near Earth. The Magnetospheric Multiscale, or MMS, […]

Astronomers Discover Dwarf Galaxies Orbiting the Milky Way

New Dwarf Galaxies Discovered in Orbit Around the Milky Way

Astronomers from the University of Cambridge have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. Astronomers have discovered a ‘treasure trove’ of rare dwarf satellite galaxies orbiting our own Milky Way. The discoveries could hold the key to understanding dark matter, the mysterious substance which holds our […]

New Research Shows How Early Human Ancestors Were Unique

Researchers Show How Early Human Ancestors Were Unique

New research from Harvard University and colleagues from around the globe reveals that the teeth of early hominins grew unlike those of either modern humans or apes, suggesting that neither can serve as a useful proxy for estimating the age or developmental progression of juvenile fossils. For nearly a century, the debate has raged among […]

Neuroscientists Find That Cognitive Skills Peak at Different Ages

Cognitive Skills Peak at Different Ages Across Adulthood

New research from neuroscientists at MIT and Massachusetts General Hospital reveals that different parts of the brain work best at different ages. Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline. However, more recent findings, including […]

Yale Study Reveals Connection Between Genes That Contribute to Autism

Study Shows Connection Between Key Autism Risk Genes

A newly published study from Yale University reveals an important connection between key autism risk genes in the human brain, a major step toward understanding how brain development goes awry in some individuals with the disorder. The research shows that CHD8, a gene that is strongly linked to autism, acts as a master regulator in […]

Coronal Mass Ejections Accelerate and Concentrate Nanodust Particles

Nanodust Observations by the Solar Terrestrial Relations Observatory

A team of astronomers has discovered that coronal mass ejections accelerate and concentrate nanodust particles in the interplanetary medium, a conclusion derived from STEREO instruments that observed an increase in the rate of nanodust impacts on the spacecraft. Dust particles smaller than about a wavelength of light are abundant in our solar system, created by […]

GC-1 Turns White Fat Into Brown Fat

Experimental Drug Turns White Fat Into Brown Fat

New research shows that the experimental drug GC-1 dramatically increases the metabolic rate, essentially converting white fat into a fat like calorie-burning brown fat. San Diego, California – An experimental drug causes loss of weight and fat in mice, a new study has found. The study results will be presented Friday at the Endocrine Society’s […]

Entanglement Can Improve Optical Sensor Performance

Entanglement Can Improve the Performance of Optical Sensors

A new study from MIT demonstrates that entanglement can improve the performance of optical sensors, even when it doesn’t survive light’s interaction with the environment. The extraordinary promise of quantum information processing — solving problems that classical computers can’t, perfectly secure communication — depends on a phenomenon called “entanglement,” in which the physical states of […]

Hubble Views Multiple Images of a Highly Magnified Supernova for the First Time

Hubble Sees Multiple Images of a Highly Magnified Supernova for the First Time

Using the Hubble Space Telescope, a team of astronomers has spotted four images of a distant exploding star for the first time. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive cluster of galaxies. The supernova discovery paper appears in a special issue of […]
