Latest Nucleosynthesis Stories
The formation of planets of stars is still somewhat of a mystery to astronomers. While much progress has been made, particularly in the last few decades, there are still unanswered questions as to how the planetary building blocks form. But now, new research may be closing that knowledge gap.
Turbulent Mixing Inside Stars Causes them to Expand, Contract, Eject and Explode, According to 3-D Model Described in the Journal "AIP Advances" WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/
The big bang theory is the leading theory to explain the origin of the Universe. But this does not mean that the big bang is without its problems.
However, in 2004 scientists unexpectedly found an ancient iron radioisotope in the Earth’s crust along the ocean’s floor. Geological dating indicates that the iron had been embedded for about 2.2 million years.
Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists is looking at the conditions necessary to the formation of those two elements in the universe.
Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box.
Astronomers have detected the presence of arsenic and selenium, neighboring elements near the middle of the periodic table, in an ancient star in the faint stellar halo that surrounds the Milky Way.
Researchers from several universities have detected all phases of thermonuclear burning in a neutron star for the first time.
Physicists find new clues to element synthesis in supernovae while exploring an 'island of inversion'.
Just like archaeologists, who rely on radioactive carbon to date the organic remains from past epochs, astronomers have exploited the radioactive decay of an isotope of aluminum to estimate the age of stars in the nearby Scorpius-Centaurus association, the closest group of young and massive stars to the Sun.
