Even Incredibly Dense Neutron Star Falls Like A Feather

Dense Neutron Star - PSR J0337+1715

Researchers test Einstein’s general relativity theory on a triple star system that is 4,200 light years away.  They found that both neutron star (heavy and dense) and white dwarf star (less massive) fall towards an outer dwarf at the same rate.  Any acceleration difference between inner white dwarf and neutron star is too small to ...

A Galaxy 11 Billion Light-Years Away Has Milky Way-Type Dust Particles

Milky Way consists of very high amount of carbonaceous dust, and now similar type of cosmic dust has been observed in galaxies 11 billion light-years away from Earth.  This comes from a recently detected ultraviolet carbonaceous dust in a gamma-ray burst, GRB180325A.    Galaxies are gravitationally bound systems comprised of numerous individual parts such as stars, ...

New, Efficient Coating Technique Makes Natural Fabrics Water-Repellent

water repellent coating technique

The new coating technique makes natural fabric water-repellent, and it works better than existing methods.  The fabrics have passed repeated washing tests and harsh abrasion tests without any degradation and damage to the coating. Waterproof fabrics are usually synthetic fibers that are coated or laminated with waterproofing materials like silicone elastomer, polyvinyl chloride (PVC), fluoropolymers, and ...

15 Brightest Stars In The Sky | Based On Apparent Magnitude

Alpha Centauri - brightest stars

The brightness of any stellar object or any object in space is measured by the apparent magnitude of that body. Well, that’s just one way to do it. Apparent magnitude is the level of brightness witnessed by an observer on the Earth. Brightness and the magnitude value have an inverse relationship, i.e. more the brightness less ...

How Big Are Neutron Stars?

How Big Are Neutron Stars - new constraints on radii

Astrophysicists determine new constraints on radii and tidal deformabilities of neutron stars.  They compared 2 billion theoretical models with gravitational waves captured in 2017.  This allowed them to deduce the size of neutron stars within a range of 1.5 kilometers: it varies from 12 to 13.5 km.  A neutron star is a collapsed core of a massive star ...

Are We Alone In the Universe? Probably YES | New Study

Are We Alone In the Universe

Astrophysicist reevaluated Drake equation using current scientific knowledge and astrobiology literature.  They concluded that there is substantial probability (up to 85%) that we are alone in the observable universe.  The astonishingly large number of stars in the universe suggests that somewhere in the distant galaxy an intelligent form of life could be warming itself. Yet we haven’t ...

Scientists Discover 1,016 Specific Genes Linked with Intelligence and Neuroticism

Brain Genes Linked with Intelligence

Scientists have identified 1,016 specific genes and 205 regions in DNA associated with intelligence. The study deepens our understanding of neurobiology of cognitive functions, and genetically linked psychiatric and neurological disorders.  Intelligence — a construct that includes problem solving abilities, language acquisition and spatial manipulation — is at the forefront of genetic research. Scientists usually ...

How Dark Matter Affects The Speed Of Gravitational Wave?

Dark Matter Affects The Speed Of Gravitational Wave

New calculations suggest that dark matter influence propagation of cosmic gravitational wave.  The effects are too small to be measured by exiting or near-future detectors.  For more than half a century, dark matter has remained one of the greatest mysteries in modern science. Dark matter and dark energy are two missing pieces of our universe that ...

Human Physiology And Surgery In Space

Human Surgery In Space

Researchers explore current understanding of human pathophysiology and surgery in space.  The extreme environment of space creates numerous unique changes in human physiology, which must be taken into consideration by future space surgery practitioners.  Humans are driven to explore the unknown, push the boundaries of scientific limits and discover new worlds. Over the last decade, private ...

Trapping Light Into Nano-Discs Much Smaller Than Its Wavelength

Polaritons oscillating inside nano-discs

Scientists used 2D boron nitride crystals to build nano-discs that trap light and create polaritons.  These nano-discs concentrate light in thousands of times smaller volume than is possible with any other material.  The technique could be used to detect tiny matter nearby polaritons, including hazardous compounds. Over the last couple of years, there has been keen ...
