University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe. Dr. Timothy Friesen, Ph.D., an associate professor of Physics and Astronomy in the Faculty of Science, and his team led a new measurement comparing the spectrum of hydrogen to its antimatter counterpart—antihydrogen.
The officers were patrolling the area following a domestic disturbance call where a person was shot; when they located the suspect, a gunfight ensued
Three Chinese astronauts returned to Earth on Friday after spending nearly seven months in space, setting a record for the longest on-orbit stay by a Chinese crew.
Past research has indicated Mars’s largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers have now identified a ring of minerals in the region that have helped them string together a timeline of what happened there. The new study, published in Nature Communications, provides details about the ocean’s timeline and what it says about life on Mars.
Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities.
Think about a census. You could photograph every house in the country and produce a beautiful map, but without knocking on doors and asking questions, you’d know almost nothing about the people living in them.
Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining the findings was posted to the arXiv preprint server on May 21.
Topological phases are unusual states of matter that give rise to properties protected by a material’s overall structure (i.e., “topology”), as opposed to microscopic details. These phases are of great interest for the development of quantum technologies, as they can yield desirable electronic properties that are robust against defects and disturbances.
A rocket belonging to Jeff Bezos’ Blue Origin exploded during a test at the launch pad Thursday night, shaking nearby homes and briefly painting the sky orange.
New York City residents and visitors look up at the sky to experience a phenomenon twice a year known as Manhattanhenge.
A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy technique called the Atom Camera, which uses a single ultracold atom at near absolute zero temperature trapped in an optical tweezer as a camera to visualize the intensity and polarization distributions of light at the nanometer (one-millionth of a millimeter) scale.
While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts.
Astronomers have found some of the strongest evidence yet that stars can swallow their own planets. A new study, published in Monthly Notices of the Royal Astronomical Society, supports the long-held belief that young stars are capable of “eating” nearby worlds as planetary systems form.
An extremely fast microscopy method to research the interaction of light and matter makes it possible to study optical processes on very short timescales. To this end, a German–Italian research team is combining holographic imaging with ultrafast spectroscopy in an innovative way. In this manner, even extremely short-lived electronic and magnetic phenomena—which play a major role in the development and application of novel energy materials—can be observed.
The universe is full of fascinating structures, and some of the most striking take shape inside the giant clouds where stars are born. There, streams of gas appear to converge from all directions toward a dense central hub, like spokes meeting at the center of a wheel.
