Voyager 1 Presents the “Sounds” of Interstellar Space

NASAs Voyager 1 Spacecraft Enters Interstellar Space

A new ScienceCast video answers the question, what does interstellar space sound like? As Voyager 1 recedes from the solar system, researchers are listening for “interstellar music” (a.k.a. plasma waves) to learn more about conditions outside the heliosphere. Scifi movies are sometimes criticized when explosions in the void make noise. As the old saying goes, […]

Research Sheds New Light on Dark Energy

Researchers Shed New Light on Dark Energy

Dartmouth researchers shed new light on dark energy and eliminate the possibility that our planet, solar system and galaxy are at the center of the universe. In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don’t explain the cosmic speed-up, […]

New Model Shows How a Collapsing Star Results in Two Black Holes that Form and Fuse

The Formation of Two Black Holes from a Collapsing Star

A new study from researchers at Caltech details the collapse of rapidly rotating supermassive stars that formed in the early Universe. The study shows that tiny perturbations cause these stars to deviate into non-axisymmetric shapes during the collapse, leading to the formation of a system of two high-spin supermassive black holes that inspiral and merge. […]

Astronomers Discover New Information about Black Hole Mergers

Study Shows Merging Black Holes Ripple Space and Time

While searching for gravitational waves generated by supermassive black holes merging, astronomers using the Parkes Radio Telescope have discovered new information about the frequency and strength of black hole mergers. Throughout our universe, tucked inside galaxies far, far away, giant black holes are pairing up and merging. As the massive bodies dance around each other […]

New Retinal Implant Technology Expected to Help Restore Sight

Retinal Implants Expected to Restore Sight to the Blind

In an effort to improve retinal implant technology, researchers have developed a new method that uses microsecond pulses, on-chip counter-electrodes, and controlled firing of electrodes to shape the electrical field, which could help people who have lost their sight see more than just light and vague shapes. Researchers at the University of Arizona and University […]

Scientists Discover New Asymmetric Topological Insulator

Scientists Discover New Asymmetric Topological Insulator

A team of scientists has discovered a new asymmetric topological insulator made of many layers of BiTeCl, which enables electrical current to flow differently along its top surface than along its bottom. Scientists working at SLAC, Stanford, Oxford, Berkeley Lab and in Tokyo have discovered a new type of quantum material whose lopsided behavior may […]

New Cassini Image of Saturn’s Rings and Moons

Cassini Spacecraft Views the Moons of Saturn

This new image from the Cassini spacecraft shows Saturn’s rings and five of its moons. Five moons pose for the international Cassini spacecraft to create this beautiful portrait with Saturn’s rings. This view, from 29 July 2011, looks toward the northern, sunlit side of the rings from just above the ringplane. At the far right, […]

Researchers Discover New Ligament in the Human Knee

Researchers Detail New Ligament in the Human Knee

Using macroscopic dissection techniques on cadavers has allowed surgeons to fully detail the anterolateral ligament (ALL) found in the human knee. Two knee surgeons at University Hospitals Leuven have provided the first full anatomical description of a previously enigmatic ligament in the human knee. The ligament appears to play an important role in patients with […]

Astrophysicists Show How Universe’s Violent Youth Seeded Cosmos with Iron

How the Violent Youth of the Universe Seeded the Cosmos with Iron

The even distribution of iron throughout the Perseus cluster has allowed astrophysicists to tell the billion-year-old story of how exploding stars and black holes sowed the early cosmos with heavy elements. New evidence that iron is spread evenly between the galaxies in one of the largest galaxy clusters in the universe supports the theory that […]
