Expert insight: Asteroid samples may reveal information about the origins of the universe
The OSIRIS-REx mission is NASA's first mission to collect samples from an asteroid - in this case 101955 Bennu - and return to Earth. OSIRIS-REx is an acronym for Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer. The sealed capsule landed on Sept. 24 near Salt Lake City, Utah, a feat that was broadcast live by NASA.

Astronomers measure the distance between Earth and 200 galaxies
In 2022, the James Webb Space Telescope captured an image of a cluster of thousands of galaxies. Astronomers have measured the distance to Earth of 200 of these galaxies. On July 11, 2022, the world saw the very first image taken by the James Webb Space Telescope (JWST). The image is now known as the "Webb Deep Galaxy Field" - a galaxy cluster named SMACS 0723, comprising over 7,000 galaxies! This image has proved an important target for the study of galaxy evolution, as this large number of very distant galaxies tells us a lot about how galaxies formed and evolved in the early Universe.

Simon Fraser researchers involved in major international antimatter breakthrough
Antimatter is tied up in one of the world's greatest mysteries. Physics predicts that when we create matter, we also create equal amounts of antimatter. Yet there seems to be almost no antimatter in our universe, a fact that has long puzzled physicists. Now, physicists at Simon Fraser University, the University of Calgary, TRIUMF, the University of British Columbia, York University and the British Columbia Institute of Technology and research institutions from around the world have just answered a long-standing question that will lead to a deeper understanding of antimatter: Does it fall down?

Does antimatter fall up or down? Physicists observe the first gravitational free-fall of antimatter
Science, Health & Technology Prof. Takamasa Momose First measurement of the force of the Earth's gravity on antimatter, which leverages a built-in-Vancouver antimatter gravity detector. In the world's first observation of the effect of gravity on antimatter, a group of researchers from Canada and around the world have made an important confirmation: like matter, antimatter does indeed 'fall downwards'.

Using machine learning to close Canada’s digital divide
Researchers use AI to detect potential problems with satellites before they happen Rural and remote communities in Canada often rely on satellites to access the internet, but those connections are fraught - with many glitches and service interruptions because the technology can be unreliable. The inequity in internet access between these communities and those who live in cities is an ongoing problem with myriad consequences for Canada's economic productivity.

New project to monitor satellites over Canada
As satellite count surges, Western team uses meteor tracking camera tech to track where they are in Earth's orbit As predicted by Captain Kirk, space is indeed the final frontier. But imagine if Starfleet couldn't launch the U.S.S. Enterprise because there was a traffic jam in Earth's orbit causing congestion or, worse, gridlock.

Star with two faces discovered thousands of light years from Earth
Science, Health & Technology Alex Walls It's not the nicest description for a human, but a two-faced star has been identified by astronomers in a first for its kind. With one side composed fully of hydrogen and the other of helium, the star has been dubbed Janus after the two-faced Roman god of transition, and described in a new study published in Nature today.

Changes in the tick of ’cosmic clocks’ reveal gravitational waves
Science, Health & Technology Alex Walls Using part of the Milky Way as an antenna, researchers have found evidence for gravitational waves that undulate over periods of years to decades by measuring changes in the tick of 'cosmic clocks', according to new research. The observations, published today in a suite of papers in The Astrophysical Journal Letters , were collected over 15 years by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center (PFC), a collaboration of more than 190 scientists including UBC astronomers.
