Montreal Astronomers Spot Possible Water-Rich Exoplanets

Montreal Astronomers Spot Possible Water-Rich Exoplanets

Water wasn’t directly detected, but by comparing the sizes and masses of the planets to models, they conclude that a significant fraction of their volume — up to half of it — should be made of materials that are lighter than rock but heavier than hydrogen or helium (which constitute the bulk of gas giant planets like Jupiter). The most common of these candidate materials is water.

Drinking water in all Quebec schools will be tested for lead

 Drinking water in all Quebec schools will be tested for lead

The drinking water in all public and private schools across Quebec will be tested for lead, Education Minister Jean-François Roberge said. Roberge ordered the tests as a precaution after La Presse reported that four elementary schools had lead levels in their water that surpassed levels recommended by Health Canada. Water samples were collected in 24 Montreal schools and were analyzed by the chemistry department at the Université de Montréal.
