Quantum Tunneling Allows “Impossible” Chemical Reactions to Occur in Space

Quantum Tunneling Allows “Impossible” Chemical Reactions to Occur

A team of scientists from the University of Leeds has discovered that chemical reactions once thought to be ‘impossible’ in the coldness of space can actually occur thanks to a phenomenon called ‘quantum tunneling.’ New research has revealed that chemical reactions previously thought to be ‘impossible’ in space actually occur ‘with vigor,’ a discovery that […]

Astronomers Deduce the Characteristics of Nanodust

Astronomers Use STEREO Spacecraft to Deduce the Characteristics of Nanodust

A team of astronomers has used the Low Frequency Receiver onboard the twin Solar Terrestrial Relations Observatory spacecraft to deduce the characteristics of nanodust, showing that this nanometer-scale dust is a significant contributor to the total mass in interplanetary space. In our solar system, dust particles are abundant, created by asteroid collisions and by the […]

Hubble Bubble Helps Explain Differing Measurements for the Expansion Rate of the Universe

Hubble Bubble Simulation

A team of physicists has developed a theoretical model to help explain some of the deviations between previous measurements of the expansion rate of the universe and the latest measurements from the Planck satellite. The existence of the “Hubble Bubble” may explain, at least in part, the differing measurements for the expansion and therefore the […]

Black Hole Powered Jets Push Material Out of Galaxy

Astronomers Discover Powerful Jets Blowing Material Out of Galaxy

Using data from an intercontinental combination of radio telescopes, astronomers have been able to see massive clumps of cold gas being pushed away from the center of galaxy 4C12.50 by black-hole-powered jets. Astronomers using a worldwide network of radio telescopes have found strong evidence that a powerful jet of material propelled to nearly light speed […]

NASA’s NuSTAR Identifies Its First Ten Supermassive Black Holes

NuSTAR Views Supermassive Black Holes

In a new study, scientists report on the first ten identifications of sources serendipitously detected by NuSTAR. NASA’s black-hole-hunter spacecraft, the Nuclear Spectroscopic Telescope Array, or NuSTAR, has “bagged” its first 10 supermassive black holes. The mission, which has a mast the length of a school bus, is the first telescope capable of focusing the […]

Study Shows Interstellar Wind Has Changed Direction

Study Shows Interstellar Wind Changed Direction Over 40 Years

Based on data spanning four decades from eleven different spacecraft, a new study shows that interstellar wind most likely changed direction over the last 40 years. Like the wind adjusting course in the middle of a storm, scientists have discovered that the particles streaming into the solar system from interstellar space have most likely changed […]
