Big planets don’t necessarily mean big moons

Does the size of an exomoon help determine if life could form on an exoplanet it’s orbiting? This is something a February 2022 study published in Nature Communications hoped to address as a team of researchers investigated the potential for large exomoons to form around large exoplanets (Earth-sized and larger) like how our moon was formed around the Earth. …read more […]

The implications of ‘Oumuamua on the panspermia theory

On October 19, 2017, astronomers with the Pan-STARRS survey detected an interstellar object (ISO) passing through our solar system for the first time. The object, known as 1I/2017 U1 ‘Oumuamua, stimulated significant scientific debate and is still controversial today. One thing that all could agree on was that the detection of this object indicated that ISOs regularly enter our solar system. What’s more, subsequent research has revealed that, on occasion, some of these objects come to Earth as meteorites and impact the surface. …read more […]

Discovery of second ultra-large structure in distant space further challenges our understanding of the universe

The discovery of a second ultra-large structure in the remote universe has further challenged some of the basic assumptions about cosmology. …read more […]

Gravitational waves could show us the first minute of the universe

Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves and infrared to gamma rays. There is a problem with studying the universe through the electromagnetic spectrum, we can only see light from a time when the universe was only 380,000 years old. An alternate approach is to use gravitational waves which are thought to have been present in the early universe and may allow us to probe back even further. …read more […]

Discovery changes understanding of water’s history on the moon

New research from a Western University postdoctoral fellow shows the early lunar crust, which makes up the surface of the moon, was considerably enriched in water more than 4 billion years ago, counter to previously held understanding. The discovery is outlined in a study published today (Jan. 15) in the journal Nature Astronomy. …read more […]

Water may have flowed intermittently in Martian valleys for hundreds of millions of years

Using impact craters as a dating tool, Planetary Science Institute Research Scientist Alexander Morgan has determined maximum timescales for the formation of Martian valley networks shaped by running water. …read more […]

Image: Hubble captures a monster merger

This NASA/ESA Hubble Space Telescope image features Arp 122, a peculiar galaxy that in fact comprises two galaxies—NGC 6040, the tilted, warped spiral galaxy and LEDA 59642, the round, face-on spiral—that are in the midst of a collision. This dramatic cosmic encounter is located at the very safe distance of roughly 570 million light-years from Earth. Peeking in at the lower-left corner is the elliptical galaxy NGC 6041, a central member of the galaxy cluster that Arp 122 resides in, but otherwise not participating in this monster merger. …read more […]

What delays to the Artemis II and III missions mean for Canada

On Jan. 9, NASA announced it would be shifting the launch of Artemis II to September 2025. Artemis III—the first mission to land humans on the surface of the moon since 1972—was moved to September 2026. …read more […]

Unlocking the magnetic superpowers of topological magnons

In the ever-evolving landscape of condensed matter physics, a recent breakthrough has emerged from the collaborative efforts of researchers at the Peter Grünberg Institute (PGI-1), École Polytechnique Fédérale de Lausanne, Paul Scherrer Institut in Switzerland, and the Jülich Centre for Neutron Science (JCNS). …read more […]

Physicists identify overlooked uncertainty in real-world experiments

The equations that describe physical systems often assume that measurable features of the system—temperature or chemical potential, for example—can be known exactly. But the real world is messier than that, and uncertainty is unavoidable. Temperatures fluctuate, instruments malfunction, the environment interferes, and systems evolve over time. …read more […]

The tale of two clocks: Advancing the precision of timekeeping

Historically, JILA (a joint institute established by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) has been a world leader in precision timekeeping using optical atomic clocks. These clocks harness the intrinsic properties of atoms to measure time with unparalleled precision and accuracy, representing a significant leap in our quest to quantify the most elusive of dimensions: time. …read more […]
