It would be an ugly experience to see our world through the eyes of a migratory bird. Something about their visual system allows them to ‘see’ our planet’s magnetic field, a clever trick of quantum physics and biochemistry that helps them find vast distances. Now, for the first time, scientists …

Although Voyager probes left our solar system years ago, as they traveled through international space, they are still searching for cosmic rays exploding 23 billion kilometers (14 billion miles) away from our sun. A detailed analysis of recent data from both Voyager 1 and Voyager 2 has now led to …

In November 2018, after the epic, after a 41-year journey, Voyager 2 finally crossed the line that marked the limits of the Sun’s influence and entered international space. But a little investigation mission is not yet complete – it is now sending home information about space outside the solar system. …

Scientists have so far measured the short-term unit: the time it takes lighter particles to cross a hydrogen atom. That time, for the record, is 247 zeptoseconds. One zeptosecond is a trillion, or decimal point, in the billions of another, followed by 20 zeros and 1. Previously, researchers had dived …
