Euclid spots a new comet
A galaxy-mapping telescope found a moving visitor close to home.
Confirmed observation · ESA
Original illustrative 3D journey from the Sun through Earth, cells and an abstract atom. Conceptual artwork, not telescope footage, microscopy, accurate scale or literal electron trajectories.
THE DAILY WONDER
A world of wonder.
Stories, discoveries and hands-on science.
Stories & discoveries
A sleeve that works like a touchscreen
Researchers weave display and touch sensing into fibres, with everyday use still to be proven.
Peer-reviewed prototype · Nature
What storm waves do to a salt marsh
A marsh can keep its ground while damage to its plants weakens part of its wave protection.
Experiment and modelling · Nature
What is a star made of?
The dark lines in a star’s rainbow identify atoms. Working out how much of each element is there requires another clue: what heat has done to their electrons.

How a hard drive writes and reads invisible magnetic bits
A hard drive turns current into a tiny magnetic pattern, preserves that pattern without power, then converts it back into an electrical signal as the disk spins.

How buried sand records time since daylight
Quartz grains can store a faint record of radiation received in darkness. Reading that signal can estimate when sediment was buried, provided sunlight really reset it and the dose history is known.

How an ice core traps pieces of ancient atmosphere
Snow leaves air connected to the sky. As burial closes those passages, ice seals atmospheric samples that scientists can recover much later.

How bones renew themselves
A skeleton stays useful by replacing small patches. Cells remove old bone, other cells build a new protein framework, and mineral gradually hardens it.
