It turns out that most objects in space have magnetic fields but itâ s quite tricky to measure them . Astronomers have developed an ingenious way to measure the magnetic field of the Milky Way using polarised light from interstellar dust grains that align themselves to the magnetic field lines . A new survey has begun this mapping process and has mapped an area that covers the equivalent of 15 times the full Moon. Many people will remember experiments in school with
Black holes are fascinating cosmic entities characterized by gravitational pulls so intense that not even light can escape once it crosses into their event horizons....
The supermassive black holes at the centres of galaxies may capture smaller black holes. Not only does this prove a place for the small black holes to grow, it also makes the supermassive ones look even bigger and brighter
The Large Hadron Collider is testing entanglement in a whole new energy range, probing the meaning of quantum theory – and the possibility that an even stranger reality lies beneath
Researchers have used quantum light to create a magnetic field with a strength that is measured in imaginary numbers
