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 […]

Massive Saturn Storm Churns Up Water Ice from Great Depths

Saturn Storm Churns Up Water Ice from Great Depths

A newly published study details a massive storm that erupted on Saturn in late 2010, finding that cloud particles at the top of the great storm are composed of a mix of three substances: water ice, ammonia ice, and an uncertain third constituent that is possibly ammonium hydrosulfide. Once every 30 years or so, or […]

Astronomers Use Pan-STARRS to Detect Brown Dwarf Companion Stars

Astronomers Study the Early Stages of Brown Dwarf Development

Using Pan-STARRS and UKIDSS, astronomers discovered 673 binaries with candidate brown dwarf companions. Astronomers trying to understand how the Sun and Earth formed, and why they have their characteristic properties, have made progress on a closely related problem: the nature of the lowest mass stars, so-called “brown dwarfs.” These stars have masses of less than […]
