CSA Astronaut Chris Hadfield performed a simple science experiment designed by grade 10 Lockview High School students Kendra Lemke and Meredith Faulkner.

Canadian astronaut Chris Hadfield continued his series of fascinating videos detailing how much different ordinary life is in zero gravity with a new tutorial explaining what happens when you cry in space.
An Internet sensation, Hadfield’s stunning daily pictures of Earth from orbit regularly go viral online, as have his videos explaining everything from how to brush your teeth in zero gravity to nail clipping to washing your hands.
Hadfield posted his latest video after tweeting that crying in space hurt.’Your eyes make tears but they stick as a liquid ball,’ he wrote. ‘In fact, they sting a bit. So — space tears don’t shed.’
To illustrate what he meant, Hadfield got a bottle of water and turned on his camera.
‘I can’t cry on command, But I’m going to take some drinking water and put it in my eye as if I was crying and see what happens,’ Hadfield said as he introduced the new video.Hadfield then squirted some fluid into his eye, which stayed there just as he predicted.
‘You see it just forms a ball on my eye,’ he said. ‘So if you keep crying you just end up with a bigger and bigger ball of water in your eye, until eventually it crosses across your nose and gets into your other eye, or evaporates, or maybe spreads over your cheek, or you grab a towel and dry it out.’As Hadfield shook his head from side to side, the blob of water clung to him.
‘Your eyes will definitely cry in space,’ he said. ‘But the big difference is tears don’t fall. So grab a hankie.’
Canadian astronaut Chris Hadfield took the helm of the International Space Station on Wednesday March 13th, marking only the second time in the outpost’s 12-year history that command has been turned over to someone who is not American or Russian.
To maintain their bone and muscle mass, astronauts need to work out two hours every day.

In this Let’s Talk Science event with students from Airdrie, Alberta, Chris Hadfield describes how a person’s sense of taste changes in weightlessness. He then shares a collection of Canadian food brought to the Station on board SpaceX’s Dragon. Maple syrup in a tube, anyone?

On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and a dazzling magnetic display known as coronal rain.
Hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, and outlining the fields as it slowly falls back to the solar surface.
