Superconductors are materials through which electricity can flow without any resistance once they are cooled below a
certain critical temperature.
As the Wolf-Rayet star sheds its mass, the stellar wind plows through the material that was around it, forming a bubble structure with a dense shell.
Titan’s surface is strikingly similar to Earth’s, with flowing rivers that spill into great lakes and seas, and the moon has storm clouds that bring seasonal, monsoon-like downpours.
In a study published in the journal Nature Astronomy this week, the scientists reported that a NASA sounding rocket instrument spotted signatures of the long-sought small solar flares.
Researchers have found that some galaxies appear brighter to astronomers’ telescopes because of faster rates at which their supermassive black holes swallow matter and spit out energy, not because of the way the galaxies face Earth, as earlier believed.
Researchers have developed computer algorithms that can accurately determine when drivers are texting or engaged in other distracting activities. The system uses cameras and Artificial Intelligence (AI) to find deviations from expected motor response and reactions
The research follows a 2015 study that produced a 3.0 volt battery with an aqueous electrolyte but was stymied from achieving higher voltages by the “cathodic challenge,” in which one end of the battery, made from graphite or lithium metal, is degraded by the aqueous electrolyte.
If confirmed, the object will rank as the second largest black hole in the Milky Way after the supermassive Sagittarius A* which is located at the very centre of the galaxy.
A near-Earth asteroid about 4.4 km in size will pass safely by our planet on Friday, at a distance of about seven million km, NASA has said.
Scientists have discovered a new method to convert dried tree leaves into a porous carbon material that can be used to produce high-tech electronics.
Tinnitus, a chronic ringing or buzzing in the ears, is associated with changes in certain networks in the brain, and those changes cause the brain to stay more at attention and less at rest, a research has found.
Tiny changes in the surface of a blown up balloon causes it to charge more when rubbed against our hair and stick to other surfaces, say scientists who have decoded why some materials acquire static charge better.
In a breakthrough, scientists have developed a steel with a high level of both strength and ductility that may have a wide range of industrial applications. The material cost of the steel is just one-fifth of that used in the current aerospace and defence applications.
Images of Antares, a red supergiant, more than 500 light-years from Earth in the constellation Scorpio, have been captured, reported Nature magazine.
The Moon’s interior is likely very dry, revealed an analysis of a ‘rusty’ lunar rock, while contradicting a study that showed evidence of water on the Moon. The results suggest that when the Moon formed it was “very, very, hot… Essentially an ocean of magma.”
