James Webb Is Redefining the Boundary Between Planets and Stars
Apr 23, 2026
New observations of 29 Cygni b suggest that the boundary between planets and stars is not as simple as once believed. How an object forms may matter more than its mass alone.
The return of humans to the Moon: why Artemis II is much more than another space mission
Mar 31, 2026
NASA is preparing for the first crewed mission toward the Moon in more than half a century, but Artemis II matters for more than its historic symbolism. This mission opens a new phase in the race for technology, presence, and influence beyond Earth orbit.
Where Is Everybody? The Fermi Paradox and the Silence of the Universe
Mar 16, 2026
If billions of potentially habitable planets exist in our galaxy, why haven't we found evidence of extraterrestrial civilizations? The Fermi paradox explores this cosmic mystery.
Quasars: cosmic beacons powered by supermassive black holes
Feb 22, 2026
Quasars are among the brightest objects in the universe despite being billions of light-years away. Here’s what they are, why they shine so intensely, how we measure them, and what they reveal about the early cosmos.
Quantum Mechanics Without the Hype: How the Microworld Really Works
Jan 30, 2026
An evergreen guide to quantum mechanics — superposition, uncertainty, and entanglement — with clear examples from space science and everyday technology.
Hubble vs James Webb: what’s the difference and why both still matter
Jan 14, 2026
Hubble and James Webb aren’t “old vs new” — they’re two telescopes that observe the universe in different ways. Here are the key differences (light, orbit, mirror) and what each one does best.
Black holes: how do we ‘see’ them if they emit no light?
Jan 7, 2026
A black hole doesn’t shine—so how do we know it’s there? From stellar orbits and X-ray sources to gravitational waves and the Event Horizon Telescope ‘shadow,’ this evergreen guide explains the strongest evidence.
How we discover planets beyond our Solar System: exoplanets, method by method
Dec 31, 2025
We can’t simply “see” most exoplanets like in movies. In reality, we detect them indirectly—through a star’s dimming, a subtle gravitational wobble, and a few other physics tricks. Here’s how it works, clearly and without hype.
Webb spots a ‘sooty’ lemon-shaped world around a pulsar — and its atmosphere makes no sense (yet)
Dec 17, 2025
JWST observed PSR J2322-2650b, a Jupiter-mass object stretched by tidal forces into a lemon shape. Its atmosphere appears dominated by helium and carbon — with soot clouds and rare molecular carbon that challenges formation theories.
Bennu: the asteroid carrying life’s sugars, 'space gum' and ancient stardust
Dec 10, 2025
New analyses of samples from asteroid Bennu reveal bio-essential sugars, a strange 'space gum' material and an unusually high amount of stardust from ancient supernovae – reshaping what we know about the origins of life and our Solar System.
Superconductors and optical fibers – from copper wires to the internet of the future
Dec 5, 2025
How zero-resistance superconductors and a new generation of optical fibers push the limits of internet speed, quantum networks and future power systems.
3I/ATLAS – the third interstellar visitor and NASA’s big photo hunt
Nov 25, 2025
The interstellar comet 3I/ATLAS is only the third known object to enter our Solar System from another stellar neighborhood. NASA has launched a multi-mission campaign to observe it from every angle.
40,000 Near-Earth asteroids: has Earth ever been better protected?
Nov 24, 2025
Astronomers have just logged the 40,000th Near-Earth asteroid. What does that mean for impact risk – and how ready are we to defend the planet?
JWST may be seeing the universe’s first stars: the mysterious galaxy LAP1-B
Nov 24, 2025
The James Webb Space Telescope may have found the first stars in the universe, in the ultra-faint galaxy LAP1-B 13 billion light-years away. How close are we to confirming the legendary Population III?
GJ 251 c – a new super-Earth just 18 light-years away
Nov 19, 2025
Astronomers have discovered the super-Earth GJ 251 c in the habitable zone of a nearby red dwarf. We explain why this planet is one of the most promising targets in the search for life.
3I/ATLAS – interstellar comet or something else entirely?
Nov 16, 2025
What we really know about the interstellar object 3I/ATLAS – from discovery and weird chemistry to theories that it might not be a typical comet.
