The Real King of the Sun

There’s no feature of the Sun that cannot be explained with my proposed model and without any contradictions. The current theory is only an elegant mathematical theory and it cannot explain any basic feature of the Sun, not just the solar neutrino problem. And let

The electrochemistry of Comets with Dr. Franklin Anariba

It is a great paradox in comet science: We are told that a comet nucleus is a ball of ice, or dirty snowball, or icy fluff ball that accreted billions of year ago in the solar system’s infancy. Comets are said to sublimate ices as they move toward the sun, and

Primordial plasma: Hot gas or streams of charged particles?

Complex rings, knots, and twisted streamers are often ejected from stars (and other celestial objects). The overall shape of so-called “planetary nebula” sometimes reveal gigantic, bifurcated jets emerging from the central star, indicating the beginnings of

Landmark study proves magnets can control heat and sound

Scientists from the The Ohio State University have discovered how to control heat with a magnetic field and presented their findings in the March 23 issue of the journal Nature Materials. The study is the first ever to prove that acoustic phonons - the elemental particl

How is Mars rover Opportunity still alive?

Today, we review one of the great ongoing mysteries in the history of Mars exploration. In January of 2004, the Mars rovers Spirit and Opportunity arrived at the red planet about three weeks apart.Due to the extreme dustiness of the Martian environment, it was believed

The mystery of solar nanoflares

Nanoflares are eruptions on the Sun which are billion times less energetic than ordinary flares but still have the power that belies their name. They appear as little brightenings of the solar surface at extreme ultraviolet and X-ray wavelengths and they might solve a l

"Baffling" Mars plumes are electric

Science news headlines around the world tell of a baffling mystery on the planet Mars. In March of 2012, amateur astronomers spotted enormous plumes jetting from the Martian surface. The plumes were more than 250 km high and several hundreds of kilometers in length.Simi

Mysterious Lovejoy comets

In the last few years, several of the comets discovered by astronomer Terry Lovejoy have provided astronomers on Earth with dramatic and unexpected displays.From the astonishing 2011 journey of comet c/2011 W3, which survived perihelion just 140,000 km above the Sun&rsq

Why don’t comets melt in the Sun?

Sungrazer comets that survive perihelion extremely close to the Sun is a longstanding puzzle for comet science. In reality, observations going back centuries reveals that a comet’s activity has little or nothing to do with solar warming.Comets sometimes flare or e

Crystal comets

The “dusty snowball” theory of comets needs attention, since there are crystals that need high temperatures to form in the matrix of at least two.Recently, the composition of comet 67P/Churyumov-Gerasimenko (67P/C-G) was discussed in the scientific press. It

The Sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?

In a few billion years, the sun will become a red giant so large that it will engulf our planet. But the Earth will become uninhabitable much sooner than that. After about a billion years the sun will become hot enough to boil our oceans.The sun is currently classified

Missing link in metal physics explains Earth’s magnetic field

Earth’s magnetic field is crucial for our existence, as it shields the life on our planet’s surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth’s core. Iron is a metal, which means it can easily conduct a flow

Small planetoids, called Near Earth Objects (NEO), are a concern for space scientists because it is thought that large rocks might strike our planet with devastating force. It is a commonly held belief that such an object caused the extinction of the dinosaurs. The
