Astronomers from Université de Montréal have discovered an Earth-sized exoplanet around a nearby small red dwarf star that appears to be carpeted with volcanoes. Björn Benneke, a Professor at the Université de Montréal and member of the Trottier Institute for Research on Exoplanets, whose team led this discovery.

Astronomers in the Canadian-led CHIME/FRB Collaboration - including researchers from the University of Toronto - have doubled the number of known repeating sources of mysterious flashes of radio waves, known as fast radio bursts (FRBs). Through the discovery of 25 new repeating sources (for a total of 50), the team has also solidified the idea that all FRBs may eventually repeat.

Science, Health & Technology Alex Walls A Canadian-led research team has doubled the number of repeating fast radio bursts, adding 25 new 'cosmic probes'. Fast radio bursts (FRBs) are cosmic radio signals: extremely short, energetic pulses of radio emission emanating from space. They're an astronomical mystery, as scientists aren't sure exactly what causes them and where they come from.

Astronomers from McGill University are part of an international team that has discovered 25 new sources of repeating fast radio bursts (FRBs), these explosions in the sky that come from far beyond the Milky Way. This discovery brings the total number of confirmed FRB sources to 50. Based on data gathered by the CHIME /FRB collaboration, the new study, published today in The Astrophysical Journal , may also bring scientists closer to understanding the origins of these mysterious phenomena.

Astronomers have successfully launched a balloon-borne telescope that has begun capturing images of the universe on its first flight above the Earth's atmosphere. The Super Pressure Balloon-Borne Imaging Telescope (SuperBIT) was flown to the edge of space by a helium-filled NASA scientific balloon the size of a football stadium.

An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting the -cosmic dawn the era after the Big Bang when stars first ignited and galaxies began to bloom. A team of scientists from across North America, Europe, and South Africa has doubled the sensitivity of a radio telescope called the Hydrogen Epoch of Reionization Array ( HERA ).

Researchers from the  Atacama Cosmology Telescope  (ACT) collaboration have submitted a set of papers to the  Astrophysical Journal  featuring a groundbreaking new map of dark matter distributed across a quarter of the entire sky and extending deep into the cosmos. The result confirms Albert Einstein's theory of general relativity - which predicts how massive structures grow and bend light - with a test that spans the 14-billion-year life of the universe.

University of Toronto researcher  Amanda Cook  has found a way to use bright signals coming from across the universe to weigh the atmosphere of the Milky Way galaxy. The radio signals she used come from the astronomical phenomenon known as fast radio bursts (FRBs) - enigmatic celestial objects that generate brief flashes of radio waves and are considered one of the biggest mysteries in astronomy.

New HyperSpace collaboration envisions secure quantum connections across the Atlantic Ocean By Elizabeth Kleisath Institute for Quantum Computing Dr. Thomas Jennewein, a faculty member at the Institute for Quantum Computing (IQC) and the University of Waterloo's Department of Physics and Astronomy, has his sights set high and wide - specifically on a quantum satellite orbiting high above the Earth to connect Canada and Europe via a secure quantum communication link.

Astronomers have revealed  the latest deep-field image  from NASA's James Webb Space Telescope, featuring never-before-seen details in a region of space named Pandora's Cluster. The new view stitches together four Webb snapshots into one panoramic image, featuring several massive galaxy clusters merging into one megacluster.

Are we alone in the universe? With the help of artificial intelligence, scientists may be one step closer to finding the answer. Led by researchers at the University of Toronto, an international team of scientists has streamlined the search for extraterrestrial life by using a new algorithm to organize the data from their telescopes into categories to distinguish between real signals and interference.

How do stars form in distant galaxies? Astronomers have long been trying to answer this question by detecting radio signals emitted by nearby galaxies. However, these signals become weaker the further away a galaxy is from Earth, making it difficult for current radio telescopes to pick up. Now researchers from Montreal and India have captured a radio signal from the most distant galaxy so far at a specific wavelength known as the 21 cm line, allowing astronomers to peer into the secrets of the early universe.
