Astronomers co-led by UdeM's Julie Hlavacek-Larrondo detect a gigantic cloud of high-energy particles 10 billions light years away from Earth. Astronomers have uncovered a vast cloud of energetic particles surrounding one of the most distant galaxy clusters ever observed, shedding new light on the evolution of galaxy clusters in the early universe.

UCalgary scientist Ben Tutolo lead author in groundbreaking study published in the journal Science It wasn't long after Ben Tutolo started as a participating scientist on NASA's Mars Science Laboratory Curiosity Rover team that he started to understand just how much information was being collected on the red planet.

According to the Standard Model of Cosmology, the expansion of our universe is driven by the simplest possible version of dark energy: an unchanging 'cosmological constant' called lambda.  "It's the start of a new era," says Will Percival, professor and director of the Waterloo Centre for Astrophysics at the University of Waterloo, and associate faculty at Perimeter Institute for Theoretical Physics.

Using the James Webb Space Telescope, astronomers led by UdeM graduate student Louis-Philippe Coulombe investigate the extreme weather patterns and atmospheric properties of LTT 9779 b. The exotic atmosphere of LTT 9779 b, a rare "ultra-hot Neptune," is coming to light thanks to observations via the James Webb Space Telescope led by Louis-Philippe Coulombe, a graduate student at Université de Montréal's Trottier Institute for Research on Exoplanets (IREx).

"Out of science fiction": First 3D observations of an exoplanet's atmosphere reveal a unique climate The first three-dimensional observations of the atmosphere of the exoplanet Tylos, in which astronomers from IREx participated, have revealed its unique climate. Joost Wardenier and Romain Allart, both IREx postdoctoral reseachers who contributed to the study.

A Canadian-led team of international astronomers has made a groundbreaking discovery about how young planets form and grow using a creative approach with unique tools of the James Webb Space Telescope (JWST). The telescope was used to study PDS 70, a young star orbited by two growing planets. This remarkable system, located 370 light-years away, gives scientists a rare chance to see how planets form and evolve during their earliest stages of development.

Stays of six months to a year in weightlessness on the International Space Station affect ocular biomechanics, but the changes don't last, according to a study led by UdeM's Santiago Costantino. The low levels of gravity (microgravity) in space cause significant changes in astronauts' eyes and vision after six to 12 months aboard the International Space Station (ISS).

McGill astronomers place FRB 20240209A in a region of space associated with a 'dead' galaxy, one that is no longer forming stars Astronomers studying the origins of enigmatic fast radio   bursts (FRBs) have made a groundbreaking discovery that could transform our understanding of the universe's most powerful and mysterious signals.

McGill-led research team's findings point to neutron stars as the probable source of fast radio bursts, one of the universe's most perplexing phenomena   An international team of scientists led by McGill researchers has provided the clearest evidence yet that some fast radio bursts (FRBs) - enigmatic, millisecond-long flashes of radio waves from space - originate from neutron stars, the ultra-dense remnants of massive stars that have exploded in a supernova.
