Metamaterial Breaks Thermal Symmetry, Enables One-Way Heat Emission
Scientists have created a groundbreaking metamaterial that breaks Kirchhoff’s law by emitting 43% more mid-infrared radiation in one direction than it absorbs. Built from layered InGaAs and tested at 512°F with a 5T magnetic field, the structure exhibits record thermal nonreciprocity. This breakthrough enables controlled one-way heat flow, a ste...

Hubble Finds Cosmic Dust Coating Uranus’ Moons, Not Radiation Scars
New Hubble Space Telescope observations have upended decades of expectations about Uranus’ moons. Scientists once thought the planet’s magnetic field darkened their backsides with radiation, but the latest data shows Titania and Oberon are collecting space dust on their leading sides instead. This “cosmic bug splatter” effect suggests dust ...

NASA's TRACERS Mission Rescheduled for 2025 to Explore Solar Wind and Earth's Magnetic Field
NASA has delayed its TRACERS mission to no earlier than 2025 to provide additional preparation time for the crew. The mission will send twin satellites to explore how solar wind interacts with Earth's magnetosphere, particularly through a process called magnetic reconnection. These high-speed solar particles can trigger auroras and impact satellite...

'Chirping Bird' Sounds Detected 150,000 Km From Earth, Baffling Scientists
This discovery has opened new avenues for the understanding of complex behavior of space radiation and its effects on our dear planet.

New Research Reveals How Dynamo Reversals Impact Mars Magnetic Fields
Recent research in Nature Communications suggests that weak magnetic fields above Martian basins may stem from prolonged dynamo reversals, which reduce field strength over time. Through cooling models, scientists revealed that these reversing processes could account for Mars’s unique magnetic history, rather than indicating an early shutdown of t...

Aurora Season in September 2024 Could Bring Vibrant Northern Lights Due to Earth's Tilt
Auroras are expected to be more intense around September's equinox due to the Russell-McPherron Effect. The phenomenon occurs when Earth's magnetic field temporarily aligns with the solar wind, allowing charged particles to penetrate and interact with our atmosphere. This interaction causes vibrant Northern Lights, especially during the equinox. Wi...

Moon Plays Key Role in Maintaining Earth's Lifesaving Magnetic Field: Study
A new model shows that the Moon's effect on the Earth goes well beyond merely causing tides.

New Technique to Detect Magnetic Fields Inside Stars
Using a technique similar to medical ultrasound, astrophysicists have for the first time developed a way to determine the presence of strong magnetic fields deep inside pulsating giant stars.
