Researchers Propose a Method to Investigate Exoplanet Surfaces

Researchers Analyze Exoplanets in Infrared Portion of Electromagnetic Spectrum to Determine Surface Composition

Researchers aim to analyze exoplanets in the infrared portion of the electromagnetic spectrum in order to better understand the surface composition of exoplanets and to help determine how prevalent Earth-like planets are in our galaxy. Numerous rocky, Earth-like worlds have been discovered by transit surveys such as the Kepler mission. For those familiar with the […]

Kepler-76b: A Hot Jupiter with Superrotation

Kepler 76b A Hot Jupiter with Superrotation

Researchers used the BEEER algorithm to identify a hot Jupiter in the Kepler light curve, Kepler-76b. Eight hundred and eighty nine exoplanets (planets around stars other than our Sun) have been discovered to date. Most of them were found using the Kepler satellite, which spots small dips in a star’s light as an orbiting planet […]

Improving Magnetic Memory by Controlling Spin Orientation

Controlling Spin Orientation in Magnetic Nanodisks Could Multiply Magnetic Memory

Researchers look to improve magnetic memory by controlling spin orientation in magnetic nanodisks. “We spent 15 percent of home energy on gadgets in 2009, and we’re buying more gadgets all the time,” says Peter Fischer of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Fischer lets you know right away that while […]

Hubble Views a Starburst Galaxy

Hubble Views a Swirl of Star Formation

Using the Wide Field Camera 3, Hubble captured this new image of starburst galaxy J125013.50+073441.5. This beautiful, glittering swirl is named, rather un-poetically, J125013.50+073441.5. A glowing haze of material seems to engulf the galaxy, stretching out into space in different directions and forming a fuzzy streak in this image. It is a starburst galaxy — […]

Computer Simulations Help Reveal the Inner Workings of Galaxy Formation

Simulation Shows the Formation of a Massive Galaxy During the First 2 Billion Years of the Universe

A newly published study details how galaxies form, using computer simulations to reveal that cool gas flows into the centers of galaxies along filaments where it is then converted into new stars. Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly […]

Evolution of the EBL Over the Past 5 Billion Years Measured for the First Time

Evolution of the EBL Over the Past 5 Billion Years

A new study details how researchers used data from blazars to measure the evolution of the EBL over the past five billion years for the first time. How much light has been emitted by all galaxies since the cosmos began? After all, every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated […]

New Distance Measurement of SS Cygni Resolves Major Astronomical Mystery

Astronomers Measure Distance to SS Cygni

Using VLBA and the European VLBI Network, astronomers were able to accurately measure the distance to double-star system SS Cygni, resolving a major problem in the understanding of a class of stars that undergo regular outbursts. Sometimes astronomy is like real estate — what’s important is location, location, and location. Astronomers have resolved a major […]

Study Reveals Turbulence Responsible for Magnetic Field Misbehavior in Solar Flares

Researchers Explain Magnetic Field Misbehavior in Solar Flares

In a newly published study, researchers from John Hopkins University detail the role of turbulence in magnetic field misbehavior of solar flares. When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force […]
