Black Hole

A black hole is an object in outer space whose the gravitational field is so strong that no matter or light can escape. Astronomers believe such regions can form from the collapse of massive stars. Researchers at Canadian institutions have contributed to theories supporting the existence of black holes.

Robotics in Canada

Robotics is the branch of engineering that concerns robots: reprogrammable, multifunction manipulators designed to move objects and complete tasks through a variety of programmed motions. The field includes the conception, design, manufacture and operation of such machines. Robotics overlaps with a variety of other electronic and engineering disciplines including artificial intelligence (AI), bioengineering, computer science, mechatronics (the engineering of both electrical and mechanical systems) and nanotechnology. In the late 20th century, Canada distinguished itself in the field with the development of the Canadarm for space missions. Despite the challenges of competing in the international market, Canadian companies, institutes and researchers are now world leaders in the development of AI applications for robotics.

Moon

The dark grey lunar surface reflects only 7% of the sunlight it receives (comparable to the reflectivity of black soil). The moon is dominated by thousands of craters, ranging from microscopic pits to gigantic Clavius, diameter 230 km.

Insect Pests

Insects and humans cohabit the Earth and have developed complex relationships. Insect pests (less than 1% of all species) are those insects that feed on, compete for food with, or transmit diseases to humans and livestock.

Quarantine Act

Canada adopted quarantine legislation in 1872, five years after Confederation. It was replaced by the current Quarantine Act, which was passed by the Parliament of Canada and received royal assent in 2005. The act gives sweeping powers to the federal health minister to prevent the introduction and spread of communicable diseases. These powers can include health screenings, the creation of quarantine facilities and mandatory isolation orders. The Quarantine Act was introduced in the wake of the severe acute respiratory syndrome (SARS) crisis of 2003. It was invoked in March 2020 in response to the COVID-19 pandemic.

Meteors, Meteorites and Impact Craters

The solar system contains many objects smaller than the planets (or their satellites) travelling in individual orbits about the SUN; space between the planets also contains myriad dust grains in the micron size range. Near Earth, dust concentrations are only a few hundred particles per cubic kilometre, but 35 000 to 100 000 t of extraterrestrial material enters the atmosphere annually, swept up by our planet from debris that is in its path or crosses its path.
