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 […]

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 […]

Coldest Brown Dwarfs Are Warmer Than Previously Thought

Study Reveals Secrets of the Coldest Brown Dwarf Stars

A newly published study measures distances, luminosities, and temperatures of brown dwarfs, finding that they are warmer than previously thought with temperatures about 400-450 K. Cambridge, Massachusetts – Astronomers are constantly on the hunt for ever-colder star-like bodies, and two years ago a new class of objects was discovered by researchers using NASA’s WISE space […]

Physicists Take a New Approach to Unify Quantum Theory and Theory of Relativity

Scientists Take a New Approach to the Unification of General Theory of Relativity and Quantum Theory

Physicists from the Max Planck Institute and the Perimeter Institute in Canada have developed a new approach to the unification of the general theory of relativity and quantum theory. Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal […]

Hubble Views Lenticular Galaxy PGC 10922

Hubble Image of Lenticular Galaxy PGC 10922

This newly released Hubble image shows lenticular galaxy PGC 10922. The NASA/ESA Hubble Space Telescope has captured this image of PGC 10922, an example of a lenticular galaxy — a galaxy type that lies on the border between ellipticals and spirals. Seen face-on, the image shows the disc and tightly-wound spiral structures of dark dust […]
