The CHIME/FRB Collaboration has doubled the number of known repeating fast radio bursts to 50, shedding light on their mysterious origins. The new discoveries suggest that all fast radio bursts may eventually repeat, with different characteristics than one-off bursts.
Researchers have discovered a sonic boom from an immense, unseen gamma-ray burst explosion. The blast generated two jets of gamma rays that crashed into surrounding gas, producing a shock wave akin to a sonic boom. This finding provides crucial new insight into the nature of gamma-ray bursts and their jets.
Astronomers have directly observed the magnetism in Supernova 1987A, a dying star that appeared thirty years ago. The detection reveals a degree of order in the magnetic field, contrary to chaotic expectations.
A team of astronomers has performed one of the highest resolution observations in astronomical history of a pulsar 6,500 light-years away, observing two intense regions of radiation around a rapidly spinning star. The observation could provide clues to the nature of Fast Radio Bursts, which may be amplified by plasma lenses.
Scientists have found a unique galaxy that contains almost no dark matter, a finding that challenges the standard ideas of how galaxies work. The galaxy, called NGC1052-DF2, has a mass similar to that of the Milky Way but only a fraction of the expected dark matter.
For the first time, astronomers have observed a cataclysmic cosmic event that generated gravitational waves detected on Earth. The event was the merger of two neutron stars in a galaxy 130 million light-years away, resulting in a supernova-like explosion.
The Dunlap Institute has received $23 million in funding to develop innovative astronomical technology, including a radio astronomy data centre and an infrared spectrograph. These projects will position Canada at the forefront of next-generation astronomy research.
Astronomers observe magnetic field of a galaxy 5 billion light-years away, finding a similar strength and configuration to the Milky Way's. This suggests galactic magnetic fields form early in a galaxy's life and remain relatively stable.
Researchers have imaged tube-like structures in the Earth's magnetosphere, which are 500 to 700 kilometers above the surface. The structures were detected by mapping variations in radio source positions and exploiting the MWA's rapid snapshot capabilities.
Researchers found water vapour abundance to be between ten and a thousand times less than predicted models, raising questions about the chemical processes involved in planet formation. The discovery has implications for searching for life on exoplanets capable of supporting it.
A team of astronomers has made the most detailed examination yet of a Jupiter-like planet beyond our Solar System, discovering a cloudy atmosphere containing carbon monoxide and water vapour. The findings suggest that the system is like a scaled-up Solar System, with gas giants forming at great distances from their parent star
