Neutron stars can be used to detect dark matter

 In today's science, the search for the nature of dark matter ranks among the greatest challenges, but the key to fully understanding this substance may well lie within the stars. Specifically, the neutron star     Scientists have inferred the existence of dark matter, but have not observed it directly. It is extremely difficult to detect dark matter particles in experiments on Earth, because dark matter particles rarely interact with regular matter. In order to detect these rare signals, we would need an enormous detector, perhaps so large that it would be impossible to build one on Earth. Natur offers an alternative option in the form of neutron stars - the entire neutron star can act as a dark matter detector. Researchers have found a way to use the information gained from these unique natural dark matter detectors more accurately in research published in Physical Review Letters. They form when giant stars explode in supernovae explosions, making them t...

A strange radio signal is coming from the Milky Way.

  A strange radio signal coming from the center of the Milky Way Galaxy has been discovered by astronomers. Researchers have been studying variations in radio waves for a long time, but the waves detected are distinct from any previously studied variations. What is unusual about this signal? According to a statement by the University of Sydney, Wang said the scientists found the new signal most strange because it had a "very high polarisation".  He explained that its light rotates with time, but that it is only in one direction at a time. Polarisation, in simple terms, describes the direction in which light waves oscillate. The study author also noted that this was a never-seen-before phenomenon. It was noted that the brightness varied dramatically and that the signal would turn on and off at random, he said, adding that the brightness varied by a factor of 100 during those episodes.  studying  radio waves for variable or transient objects is one way to unravel...

2 sci-fi concepts that are possible (in theory)

Wormholes As a story-driver, the wormhole - a shortcut through space - seems to be a fictional concept. It existed long before sci-fi writers became familiar with it under its more formal name of an Einstein-Rosen bridge. It comes out of Albert Einstein's theory of general relativity, which views gravity as a distortion of space-time caused by massive objects. Theorizing that black holes have a direct connection to each other in 1935, Einstein worked with physicist Nathan Rosen. Wormholes grew out of this analysis. In the 1980s, astrophysicist Carl Sagan decided to write a sci-fi novel, he began considering the idea of actually traveling through a wormhole. Physicist Kip Thorne developed a rapid method for traveling interstellar distances based on Sagan's advice, according to the BBC. Thorne duly devised a way — possible in theory, but highly improbable in practice — that humans might achieve interstellar travel by traversing a wormhole unscathed. After being adapted into...

Earth's shine seems to be fading due to global warming as the oceans heat up

  In recent years, the climate change crisis has escalated to unprecedented levels, resulting in unimaginable and life-changing consequences. An acclaimed new study contends that global warming is dimming our planet, literally! Global warming is causing the Earth's brightness to decrease, according to a new study. Now you're probably wondering, "how do you even measure something like that?" But researchers have their ways. Keeping track of the Earth's shine requires them to calculate the Earth's 'albedo', or reflectance. The albedo is calculated utilizing something called the 'earthshine'. The crescent moon is most noticeable immediately after sunset or before sunrise, when its dazzling crescent gives way to a dark disc with a faint glow. A crescent moon's unlit parts are known as earthshine because they are glowing from the light reflected from the Earth. The study revealed that earthshine data over the last three years indicates that our ...

Researchers study the phase behavior of superionic water

  Researchers at Lawrence Livermore National Laboratory have developed machine learning techniques to study the phase behavior of superionic water - a phase in which hydrogen becomes liquid while oxygen remains solid-like on a crystalline lattice - with unprecedented resolving power. It is thought that superionic water can exist at depths greater than approximately one third of the radii of Uranus and Neptune, as it makes up the majority of the mantles of these ice-giant planets. Over three decades ago, superionic water was first proposed; however, it started to be measured recently and its optical properties (partly opaque) and oxygen lattices have been discovered recently. Planetary science depends heavily on understanding its properties, which are difficult to determine experimentally or theoretically. As a result of shorter simulation timeframes and small system sizes, superionic water simulations typically get a bit uncertain about the location of phase boundaries such a...

How far we have explored space and how far can we go? || The James Webb Space Telescope

  141 AU which is equal to 141 times the distance between Earth and Sun, Voyager 1 is able to travel the most in history. Even after traveling at the speed of 17 km/sec in space, which may sound a lot, it will take 1,700,000,000 years for Voyager 1 to cross the Milky Way Galaxy. Proxima Centauri, the second closest star from Earth after Sun is 4.2465 light years away and it would take 40,000 years for Voyager 1 to reach it. Parker Solar Probe recorded the highest speed in space which is 692,000 km/h and still, it would take more than 50,000 years to reach destinations like Proxima Centauri.  Now if we need to explore exoplanets, the factor we need to develop is speed. Out of many ways, the most well-known way to travel faster in space is Warp Drive where we use Antimatter to gain speed. Antiatoms are successfully built and research over Antimatter is being done. Big Bang should have produced a huge amount of Antimatter which may be lying far away in Universe The James We...
