A new fullertube molecule is found
A new fullertube molecule is found
UdeM doctoral candidate in physics Emmanuel Bourret leads an international research group that has discovered C130, a rare carbon molecular structure. For years, C 130 fullertubes-molecules made up of 130 carbon atoms-have existed only in theory. Now, leading an international team of scientists, an UdeM doctoral candidate in physics has successfully shown them in real life - and even managed to capture some in a photograph.

'brown dwarfs' grow old alone
’brown dwarfs’ grow old alone
The interstellar objects are usually paired as binary systems, but in a new study Clémence Fontanive shows that, as they get older, few actually keep their companion. Clémence Fontanive , a researcher at Université de Montréal's Trottier Institute for Research on Exoplanets, used NASA's Hubble Space Telescope to study some of the coldest and lowest-mass "brown dwarfs" of our solar system.

Discovery tests theory on cooling of white dwarf stars
Discovery tests theory on cooling of white dwarf stars
Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are "dead stars" that continuously cool down over time. New research published in Nature is challenging this theory, with the University of Victoria (UVic) and its partners using data from the European Space Agency's Gaia satellite to reveal why a population of white dwarf stars stopped cooling for more than eight billion years.

Metal 'scar' discovered on cannibal star: Study
Metal ’scar’ discovered on cannibal star: Study
Western researcher part of team that found a unique signature of a star ingesting surrounding planets and asteroids When a star like our Sun reaches the end of its life, it can expand to ingest the surrounding planets and asteroids that were born with it. Using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, researchers, including Western physics and astronomy professor emeritus John Landstreet , have found a unique signature of this process for the first time, a scar imprinted on the surface of a white dwarf star.

Destruction of an Earth oceans' worth of water per month in Orion Nebula
Destruction of an Earth oceans’ worth of water per month in Orion Nebula
An international team, including Western astrophysicists Els Peeters and Jan Cami , has shed light on the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula. This discovery was made possible by an original multidisciplinary approach combining observations from the James Webb Space Telescope (JWST) and quantum physics calculations.

Water vapour discovered in a small exoplanet's atmosphere
Water vapour discovered in a small exoplanet’s atmosphere
With a diameter approximately twice that of Earth, GJ 9827d could be an example of a planet with a water-rich atmosphere, according to astronomers at UdeM. A Canadian-led team of astronomers using NASA's Hubble Space Telescope reports observing the smallest exoplanet to have water vapour detected in its atmosphere.

New paper explores four nearby fast radio burst sources
New paper explores four nearby fast radio burst sources
Fleeting blasts of energy from space, known as fast radio bursts (FRBs), are a cosmic enigma. A Canadian-led international team of researchers has published new findings suggesting that supernovae are the predominant contributors to forming sources that eventually produce FRBs. "Fast radio bursts are one of astronomy's greatest mysteries," said lead author Mohit Bhardwaj, a member of the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) collaboration and a McWilliams Postdoctoral Fellow at Carnegie Mellon University.

Euclid’s first glimpse of the universe
ESA's Euclid space mission unveils stunning full-colour images of the cosmos, setting a new standard for astronomical imaging precision By Jordan Flemming University Relations Today, the European Space Agency's (ESA) Euclid space mission reveals five of its first full-color images of the cosmos. For the first time, Euclid has harnessed the power to capture razor-sharp astronomical images across a vast expanse of the sky, delving deep into the distant universe.

Astronomers now know how far the Earth is from 200 galaxies
Astronomers now know how far the Earth is from 200 galaxies
A Canadian-led team of scientists finds triple the number of galaxies visible in the James Webb Space Telescope's "First Deep Field" image whose distances from Earth can be measured. On July 11, 2022, the very first image taken by the James Webb Space Telescope (JWST) was released to the general public.

Astronomers measure the distance between Earth and 200 galaxies
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.

New nanomaterial may solve long-standing fuel cell issue
There is an urgent need to address climate change, making the development of sustainable energy alternatives more important than ever. While proton-exchange membrane fuel cells (PEMFCs) have shown great promise for energy production, particularly in the transportation industry, there is a long-standing problem with their durability and cost.

Simon Fraser researchers involved in major international antimatter breakthrough
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?

Researchers make a significant step towards reliably processing quantum information
Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing future functional quantum computers. This new method, developed at the University of Waterloo's Institute for Quantum Computing (IQC), uses a small glass waveguide to separate laser beams and focus them four microns apart, about four-hundredths of the width of a single human hair.
