Why Are Sunsets So Pretty In Winter? There's A Simple Explanation
If you live in the southern hemisphere and have been stopped in your tracks by a recent sunset, you may have noticed they seem more vibrant lately. The colours are brighter and bolder, and they linger longer in the sky.

Massive X1.1-class Solar Flare Causes Radio Blackouts Across America
A strong X1.1-class solar flare erupted from sunspot AR4046 on March 28, 2025. The flare caused major radio blackouts in North and South America, affecting high-frequency communications. A coronal mass ejection (CME) followed the flare but is not expected to hit Earth. More solar activity is anticipated from sunspot AR4046 and AR4048, with a 15% ch...

NASA’s EZIE Satellites Begin Mission to Study Auroral Electrojets and Space Weather
NASA’s Electrojet Zeeman Imaging Explorer (EZIE) mission has been launched aboard a SpaceX Falcon 9 from Vandenberg Space Force Base. The trio of small satellites will map auroral electrojets, powerful currents in Earth’s atmosphere linked to solar storms. Their data will enhance space weather prediction models and help understand planetary mag...

Aditya-L1’s SUIT Telescope Captures First-Ever Solar Flare Kernel, Revealing Unseen Solar Activity
India’s Aditya-L1 mission has achieved a historic milestone with its Solar Ultra-violet Imaging Telescope (SUIT) capturing the first-ever solar flare kernel in the near-ultraviolet spectrum. This unprecedented observation confirms energy transfer across different layers of the Sun's atmosphere, advancing the understanding of solar flares and spac...

AMS Data Reveals Charged Particle Variations in Heliosphere Over Solar Cycle
Researchers analysing AMS data aboard the ISS have identified variations in charged particles within the heliosphere over an 11-year solar cycle. Shifts in the heliospheric magnetic field impact antiproton behaviour and cosmic nuclei fluxes, revealing correlations between solar modulation and cosmic ray movement. AMS measurements provide insights i...

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

NASA Awards Johns Hopkins University Contract for Suprathermal Ion Sensor Development
NASA has awarded a $20.5M contract to Johns Hopkins Applied Physics Laboratory to develop Suprathermal Ion Sensors under NOAA's Space Weather Next Programme. The sensors will play a pivotal role in monitoring ions and solar winds, aiding early warnings against space weather impacts. Spanning a period through 2034, the project also involves integrat...

Solar Orbiter Sends High-Resolution Images of Sun’s Surface, Unveiling New Details
The Solar Orbiter spacecraft has sent back the sharpest images of the sun’s surface, captured from 74 million kilometres away. These high-resolution images reveal the sun’s dynamic surface features, including granular patterns and sunspots. The spacecraft’s instruments also provided detailed maps of the sun’s magnetic fields, shedding light...

Quantum Breakthrough Observed as Scientists Define Photon Shape for the First Time
In a major scientific achievement, researchers at the University of Birmingham have defined the shape of a single photon for the first time. The study reveals how photons interact with their surroundings and emit energy, providing new insights into quantum physics. This work opens avenues for innovations in nanophotonic technologies, such as improv...

NASA's Voyager 2 Finds Clues of Ancient Ocean on Uranus' Moon Miranda
Recent analysis of images captured by NASA's Voyager 2 has suggested that Miranda, a moon orbiting Uranus, may have once contained a significant ocean beneath its icy exterior. Research led by Tom Nordheim at Johns Hopkins Applied Physics Laboratory reveals that this ocean could have existed hundreds of millions of years ago, driven by tidal forces...

Supercooling of Earth's Inner Core May Finally Reveal its True Age, Highlights New Report
New research into Earth’s inner core suggests that supercooling, a process where a liquid cools below its freezing point without solidifying, may reveal that the core is much younger than previously thought. Composed of iron and nickel, the core plays a critical role in maintaining Earth’s magnetic field, which protects the planet from harmful ...

IIT Guwahati Researchers Develop Alternative to ACs With Radiative Cooling System Which Needs No Electricity
Researchers at the Indian Institute of Technology, Guwahati, have designed an affordable 'radiative cooler' coating material. The new system will act as an alternative to air-conditioners. For daytime operation, these coolers need to reflect entire solar radiation.
