Just a few days in simulated microgravity can subtly change the way women's blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser researchers. First reported in 2020, an International Space Station mission detected an unexpected blood clot in a female astronaut's jugular vein.

New astronomical find is 8.5 billion years old and reshapes our understanding of early cosmic evolution Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams that trail behind them.

Two new studies reveal structural complexity in the galaxy For centuries, astronomers have been observing celestial bodies and trying to understand the mysteries of the night sky. Dr. Jo-Anne Brown , PhD'02, wants to map an invisible force of the Milky Way galaxy: its magnetic field. "Without a magnetic field, the galaxy would collapse in on itself due to gravity," says Brown, a professor in the Department of Physics and Astronomy at the University of Calgary.

Scientists have found a planet that challenges the long-held assumption that lava planets are too hot to sustain an atmosphere. Waterloo Scientist Dr. Lisa Dang, physics and astronomy professor, and her collaborators made this discovery when they found a thick atmosphere around the rocky exoplanet TOI-561 b after flagging it as a planet of interest.

Using images from the James Webb Space Telescope (Webb), an international research team including Western's Stanimir Metchev has discovered new answers to explain how some brown dwarfs form giant dust storms, contradicting previous assumptions. These storms may look similar to Jupiter's iconic Great Red Spot, but the new study, led by Shanghai Jiao Tong University, shows they actually form quite differently.

McGill-led research using the James Webb Space Telescope sheds new light on how planetary atmospheres evolve Using the James Webb Space Telescope (JWST), a team led by McGill researcher Vigneshwaran Krishnamurthy has observed a giant cloud of helium gas evaporating from a distant giant exoplanet called WASP-107b.

Study reveals patchy clouds and shifting atmospheric layers on a free-floating planetary-mass object just 20 light-years away, offering potential insights into planet and star formation Researchers at McGill University and collaborating institutions have mapped the atmospheric features of a planetary-mass brown dwarf, a type of space object that is neither a star nor a planet, existing in a category in-between.

More than 100 scientists, including meteor physicists from Western University (Western Space), completed first-ever comprehensive study of asteroid tracked from space to impact on Earth A large international collaboration of nearly 100 researchers, led by Western adjunct professor Auriane Egal, has completed the first-ever comprehensive study of an asteroid tracked from space through to its impact on Earth.

The American observatory and its many partners, including UdeM, celebrate the detection in 2015 of gravitational waves and confirm a theorem by the late Stephen Hawking.

Silane is detected in the atmosphere of a brown dwarf, a celestial body halfway between a star and a planet, an international team of astronomers finds. Several brown dwarfs - celestial objects whose mass lies somewhere between that of stars and planets - are being studied closely with the James Webb Space Telescope, and in one of them, a previously undetected molecule has now come to light.

Researchers use newly deployed CHIME Outrigger telescopes and deep-space imaging to challenge long-held assumptions about what causes the mysterious cosmic signals. A team of international astronomers, including McGill researchers, have pinpointed one of the brightest fast radio bursts (FRBs) ever detected to a location in a nearby galaxy.

Could Earth-sized exoplanets be habitable? Based on observations with the James Webb Space Telescope, UdeM graduate Caroline Piaulet-Ghorayeb and her team suggest it's still too soon to say. Université de Montréal doctoral graduate Caroline Piaulet-Ghorayeb and her team are unequivocal: TRAPPIST-1 d, the third planet orbiting the small star TRAPPIST-1, doesn't have an Earth-like atmosphere.

Using NIRPS, a new infrared spectrograph installed in Chile, astronomers from UdeM and elsewhere unveil their initial findings in detect exoplanets and their atmospheres with the technology. A new milestone in space exploration was reached today with the publication in Astronomy & Astrophysics of the first scientific results from the Near-InfraRed Planet Searcher (NIRPS), co-led by scientists at Université de Montréal.

A team led by UdeM researchers confirms a fifth potentially habitable planet around L 98-59, a red dwarf 35 light-years away. A team led by the Trottier Institute for Research on Exoplanets (IREx) at the Université de Montréal has achieved the most precise study to date of the L 98-59 planetary system, and confirmed the existence of a fifth planet in the star's habitable zone, where conditions could allow liquid water to exist.

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.
