Mini-Neptunes and super-Earths up to four times the size of our own are the most common exoplanets orbiting stars beyond our solar system. Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown away. In a new study published in The Astrophysical Journal, astronomers from McGill University show that some of these exoplanets never had gaseous atmospheres to begin with, shedding new light on their mysterious origins.
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, according to a Canadian-led team of astronomers, including McGill University Professor Eve Lee.
The Faculty of Science is celebrating McGill’s 200th anniversary with a student art exhibition on the theme of “Science!”. McGill students at all levels and all faculties are invited to submit works in any medium, expressing what science means to them.
Faculty of Science bicentennial committee member, Torsten Bernhard, says the aim of the exhibition is to celebrate science in all its forms.
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 – a much narrower window than the Intergovernmental Panel on Climate Change’s estimate of between now and 2052. In a study published in Climate Dynamics, researchers from McGill University introduce a new and more precise way to project the Earth’s temperature. Based on historical data, it considerably reduces uncertainties compared to previous approaches.
A Canadian-led team of astronomers, including researchers from McGill University, has discovered that a repeating fast radio burst (FRB) originating from a nearby galaxy pulses at regular intervals.
Researchers within the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Fast Radio Burst Collaboration used the CHIME telescope in British Columbia to show that the repeating radio source known as FRB 180916.J0158+65 – first discovered in 2018 by the same group - pulsates apparently every 16.35 days.
Crowdmark – an online grading tool developed especially to handle large classes – has been attracting a growing following across North America, with members of McGill’s own Faculty of Science among its most ardent enthusiasts. Kira Smith, reporter-at-large for the OSE, went undercover to find out more.
McGill University astrophysicist Matt Dobbs is the recipient of the 2019 Killam Research Fellowship in Natural Sciences.
The announcement was made today by the Canada Council for the Arts, which revealed this year's winners of the prestigious Killam Program, composed of the Killam Prizes and the Killam Research Fellowships.
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), the most massive and complex science experiment in human history, is a prime example of global achievement through collaboration. Driven by a multinational community of researchers, engineers, and technicians from over 100 countries, the LHC has enabled us to push the boundaries of scientific knowledge.
Cosmologist Jonathan Sievers and international-relations scholar Jennifer Welsh will become Canada 150 Research Chairs at McGill University. The appointments were among the 24 Chairs announced today at the Canadian Museum of History in Gatineau, Quebec, by Minister of Science Kirsty Duncan.
The afterglow from the distant neutron-star merger detected last August has continued to brighten – much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light years away and sent gravitational waves rippling through the universe.
Astronomers have pinpointed for the first time the home galaxy of a Fast Radio Burst, moving scientists a step closer to detecting what causes these powerful but fleeting pulses of radio waves. FRBs, which last just a few thousandths of a second, have puzzled astrophysicists since their discovery a decade ago.
A new study published in Nature Communications could help biologists understand how various types of migratory cells, such as immune cells, find their way through tissues in the human body.

Astronomers for the first time detect repeat ‘fast radio bursts’ from same sky location
Astronomers for the first time have detected repeating short bursts of radio waves from an enigmatic source that is likely located well beyond the edge of our Milky Way galaxy. The findings indicate that these “fast radio bursts” come from an extremely powerful object which occasionally produces multiple bursts in under a minute.

McGill researchers Elena Bennett and Yasser Gidi also honoured by NSERC
The Natural Sciences and Engineering Research Council of Canada (NSERC) has named McGill University astrophysicist Vicky Kaspi as this year’s recipient of the Gerhard Herzberg Canada Gold Medal for Science and Engineering, NSERC’s highest honour, in recognition of the excellence and influence of her research contributions.
