James Webb Space Telescope Reimagines Hubble’s Deep Field, Unveils Ancient Galaxies
The James Webb Space Telescope has re-imaged part of Hubble’s Ultra Deep Field, revealing over 2,500 galaxies in stunning infrared detail. Using its NIRCam and MIRI instruments, Webb observed faint galaxies dating back to just a few hundred million years after the Big Bang. This is part of the JADES survey, which includes the deepest mid-infrared...

Hubble Unveils Dark Matter Web in Stunning Abell 209 Galaxy Cluster Image
NASA/ESA’s Hubble Space Telescope has released a stunning new image of Abell 209, a massive galaxy cluster 2.8 billion light-years away in Cetus. The golden cluster houses over 100 galaxies, but beneath them lies an invisible web of hot gas and dark matter. Using gravitational lensing, Hubble reveals curved arcs of light from background galaxies,...

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...

FireSat Protoflight Satellite to Scan Earth Every 20 Minutes for Early Wildfire Detection
Muon Space’s FireSat project will form a 50-satellite constellation that scans the planet every 20 minutes to detect wildfires using multi-band infrared imaging. The constellation aims to support first responders and policymakers with high-resolution thermal data, bridging a critical gap in satellite-based wildfire detection. Its first satellite ...

James Webb Telescope Captures First Direct Image of Saturn-Mass Exoplanet
NASA’s James Webb Space Telescope has reached a major milestone by capturing its first direct image of TWA 7 b, a newly discovered Saturn-mass exoplanet orbiting the young star TWA 7. Using a coronagraph to block starlight, Webb identified the planet embedded in the star’s dusty ring system. TWA 7 b is the smallest exoplanet ever imaged dir...

Is Mars Really Red? A Physicist Explains the Science Behind Its Colour and More
A physicist explains the science behind Mars’s red appearance, linking its hue to iron oxide or rust. While known as the Red Planet, rover images and telescope data show varied colors, from tan to white ice caps. Observations in ultraviolet and infrared light reveal deeper insights into Mars’s atmosphere, surface, and seasonal changes, enrichin...

Hubble Unveils Galactic ‘Cotton Candy’ in the Large Magellanic Cloud
NASA’s Hubble Space Telescope has captured a breathtaking image of glowing gas and dust in the Large Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. The colorful filaments—nicknamed “galactic cotton candy”—highlight active star-forming regions. Taken with five filters across ultraviolet to infrared wavelengths, the image reveals ...

Apple AirPods With Built-in Camera Said to Launch Next Year; No Major Upgrades Till 2026
Apple is said to move away from making any significant upgrades to AirPods till 2026. The company refreshed its AirPods lineup last year with the introduction of AirPods 4 — a product which also finally brought active noise cancellation (ANC) to the base TWS earbuds. However, the story for this year may not be the same. Next year, the iPhone make...
