Scientists Reveal Saturn’s Youthful Appearance is the Result of Layered Convection

Researchers Discover Why Saturn Appears Young

In a new study, scientists from the University of Exeter and the Ecole Normale Supérieure de Lyon reveal that Saturn’s youthful appearance is due to its inability to cool down, suggesting that the interior structure, composition and thermal evolution of giant planets may be more complex than the conventional approximation of giant planets as homogeneous […]

VLA Identifies Discrete Sources of Radio Waves Coming from Distant Galaxies

VLA Gives Detailed Image of Distant Universe

Using data from the Very Large Array, astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies. Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA), astronomers have for the first […]

NASA’s Fermi Dodges a Defunct Cold War Spy Satellite

NASAs Fermi Nearly Collides With a Defunct Cold War Spy Satellite

NASA’s Fermi Gamma-Ray Space Telescope has a close call with the 3,100-pound Cosmos 1805, a defunct Cold-War spy satellite, avoiding a near collision. NASA scientists don’t often learn that their spacecraft is at risk of crashing into another satellite. But when Julie McEnery, the project scientist for NASA’s Fermi Gamma-ray Space Telescope, checked her email […]

Chandra Reveals an Enormous Cloud of Hot Gas Enveloping Two Colliding Galaxies

Enormous Cloud of Hot Gas Enveloping Two Colliding Galaxies

A burst of star formation that lasted for at least 200 million years may be responsible for a cloud of hot gas, which contains the mass of 10 billion Suns, spans 300,000 light years, and radiates at more 7 million degrees, that is surrounding two merging spiral galaxies. Scientists have used Chandra to make a […]

Scientists Control Chirality in Carbon Nanotubes

Controlling Chirality in Nanotubes

A team of researchers have managed to control chirality in carbon nanotubes, achieving an epitaxial formation of Co nanoparticles by reducing a well-developed solid solution in CO. An ultimate goal in the field of carbon nanotube research is to synthesize single-walled carbon nanotubes (SWNTs) with controlled chiralities. Twenty years after the discovery of SWNTs, scientists […]

Researchers Increase the Stiffness of Silicone Liquid Crystal by 90 Percent

Silicone Liquid Crystal May Lead to Self Healing Materials

In a newly published study, researchers from Rice University report that the liquid crystal phase of silicone becomes 90 percent stiffer when silicone is subjected to a low-amplitude (5%), repetitive (dynamic) compression. Houston – Squeeze a piece of silicone and it quickly returns to its original shape, as squishy as ever. But scientists at Rice […]

Herschel Runs Out of Liquid Coolant, Stops Making Observations

Herschel Observatory Ends Observations

Launched roughly four years ago, the Herschel space telescope has run out of liquid coolant and has stopped making observations. Pasadena, California — The Herschel observatory, a European space telescope for which NASA helped build instruments and process data, has stopped making observations after running out of liquid coolant as expected. The European Space Agency […]

Cassini Views a Spinning Vortex at Saturn’s North Pole

Cassini Views Saturns North Pole

Taken by NASA’s Cassini spacecraft, this NASA image of the day shows the spinning vortex of Saturn’s north polar storm. The spinning vortex of Saturn’s north polar storm resembles a deep red rose of giant proportions surrounded by green foliage in this false-color image from NASA’s Cassini spacecraft. Measurements have sized the eye at a […]

Hubble Views Young Star PV Cep

Hubble Image of Young Star PV Cep

This Hubble image shows the young star PV Cep, which is located in the northern constellation of Cepheus at a distance of over 1600 light-years from Earth. The Universe is rarely static, although the timescales involved can be very long. Since modern astronomical observations began we have been observing the birthplaces of new stars and […]

Preprogrammed Immune Cells Can Fight Specific Pathogens

Preprogrammed Immune Cells Can Fight Specific Pathogens

A new study from Cornell University demonstrates a way to grow preprogrammed immune cells that can fight specific pathogens, potentially transforming the methods used to prevent infectious disease. Immune cells in newborns appear to be more ready to do battle than previously thought. New Cornell research shows that small populations of preprogrammed immune cells can […]

New ScienceCast Video Explores the Possibility That Signs of Dark Matter Have Been Detected

Alpha Magnetic Spectrometer Detects Possible Signs of Dark Matter

The below four minute ScienceCast video explores the possibility that the Alpha Magnetic Spectrometer onboard the International Space Station has detected signs of dark matter. In science fiction, finding antimatter on board your spaceship is not good news. Usually, it means you’re moments away from an explosion. In real life, though, finding antimatter could lead […]
