The first known astronomical measurement using parallax didn't involve a star but themoon. The ancient Greek astronomerHipparchusreportedly used observations of asolar eclipsefrom two different locations to calculate the distance of Earth's celestial companion. In 1672, Italian astronomerGiovanni Cassinian...
I’ve never seen New Zealand cast in a dark or menacing cinematic light, having been used to stuff like the fantastical dazzle of Peter Jackson’s Middle Earth and the quaint, quirky whimsy of Taika Waititi’s fare. Not being that well versed in films coming from the country, I was fa...

Neptune, which takes 165 Earth-years to orbit the sun and is about four times the diameter of Earth, is the closest solar-system object to the sun that is never visible to the unaided eye. (Uranus, for all practical purposes, usually can't be seen from Earth without binoculars or a te...
Well, on Earth, a kilometre may be just fine. It is a few hundred kilometres from New Delhi to Ghaziabad; it is a few thousand kilometres from New Delhi to Pune. In the universe, the kilometre is just too small to be useful. For example, the distance to the ...
Next up, you'll dive into arrangement and composing, led by composer and conductor Jack Vaughan. He's been teaching and directing music for over a decade. One student explains his teaching style perfectly: not only does he explain concepts so they're simple to understand, "he shows you rig...
That’s time dilation (5 years for Earth, but 3 years for the spaceship). Length contraction is a little more subtle. Normally when you measure something you get out your meter stick (or yard stick, depending on where you live), put...
A self-powered sensor developed at the University of Waterloo could allow doctors to remotely monitor the recovery of surgical patients.
A necessary part of any animal's sense of direction is a positioning system to detect the relationship between where it is and where it wants to go; this is known as odometry. Tarantula wolf spiders have four sets of eyes, and a study from the Autonomous
Using the NASA/ESA Hubble Space Telescope an international team of astronomers has measured the distance to this new galaxy, named GN-z11. Although extremely faint, the galaxy is unusually bright considering its distance from Earth. The distance measurement of GN-z11 provides additional strong evid...
