"Waterloo researchers capture first “image” of a dark matter web that connects galaxies"
This is the first time that "dark matter", which makes up most of the mass in the universe but cannot yet be detected directly, is shown to connect galaxies in the "cosmic web". The data were collected at the Canada France Hawaii Telescope on Mauna Kea (CFHT).

"Astronomers piece together first image of black hole"
Although we know black holes exist, by their very nature you can't see them as light is unable to escape once it's inside what's known as the "Schwarzschild radius" or the event horizon. This is an attempt to image a black hole by comparing the area in which you see nothing to the region around it, which is very bright due to the emission from all the hot material falling into the black hole. A bit like looking straight down a plug hole as the water drains around it.
To achieve the resolution required, telescopes from around the world were used to synthesize a telescope with roughly the same diameter as the Earth. This included the JCMT on Mauna Kea.
The results should be available in a few months.
