Nested morphology of gas streams confirms a mechanism that helps infant stars to grow by ingesting disk material. Planet-forming disks, maelstroms of gas and dust swirling around young stars, are nurseries that give rise to planetary systems, including our solar system. Astronomers have discovered new details of gas flows that sculpt and shape those disks over time.

Led by a team at UdeM's IREx, scientists explore the exoplanet GJ 9827 d'and find a significant amount of water vapor in its atmosphere. A Canadian-led international study has revealed new insights into the atmosphere of GJ 9827 d - an exoplanet orbiting the star GJ 9827 in the constellation Pisces, about 98 light-years from Earth - using the James Webb Space Telescope (JWST).

A team of scientists including researchers from the University of Bern, the University of Geneva and the NCCR PlanetS used the ESPRESSO Spectrograph to discover a sub-Earth mass exoplanet orbiting Barnard's star, the second-closest star system to the Sun. This discovery helps to understand planetary formation around red dwarfs and provides insights into the diversity of planetary systems in our cosmic neighbourhood.

Atom interferometric quantum sensors are huge, but a U-M research group has devised a way to miniaturize them Atom interferometers are quantum sensors that use the wave-like nature of atoms to measure gravity, acceleration and rotation with exceptional precision. Most of the current atom interferometers are large instruments, occupying buildings and requiring towers that can reach tens of meters in height.

Engineers work on NASA's Voyager 2 at JPL in March 1977, ahead of the spacecraft's launch that August. The probe carries 10 science instruments, some of which have been turned off over the years to save power. Credit: NASA" The mission has been working to postpone the shut-off as long as possible. Four other instruments aboard the interstellar spacecraft continue to operate.

Picture walking outside on a dark, cloudless evening. You look up to admire the stars - maybe even a planet, if you're lucky - and a sense of wonder washes of you. New research from the University of Washington shows this might be more than a memorable experience: It could ultimately spark scientific curiosity and influence life choices.

A UK team of researchers including UCL's Professor Lucie Green are working on the launch of a spacecraft mission which will allow us to view the Sun's atmosphere in more detail than ever before. The proposed MESOM mission will enable researchers to study the conditions that create solar storms, leading to improvements in forecasts of space weather on Earth.

ETH spin-off Terensis is able to forecast the harvest yield and climate risks such as droughts and frost with the help of satellites.

A trio of new studies suggests the Milky Way has a unique configuration of satellite galaxies surrounding it. A long-term survey of small, "satellite" galaxies that orbit larger galaxies across the universe offers new insights into our own galaxy, the Milky Way. Since 2012, the Satellites Around Galactic Analogs (SAGA) Survey has studied the regions around 101 galaxies that are similar to the Milky Way - finding hundreds of smaller, low-mass satellite galaxies orbiting around them.

Astrophysicist Dr Laura Driessen from the School of Physics talks us through where mini-moons come from and lets us know if we will discover more little friends for the Moon anytime soon. Earth is going to have its very own mini-moon from  September 29 until November 25 . The regular Moon's new, temporary friend is 2024 PT5, an asteroid captured from the Arjuna asteroid group (called the "Arjunas").

The precise distances from Earth of more than 1.8 million galaxies have been revealed in a sky survey involving UCL researchers. The Physics of the Accelerating Universe Survey (PAUS), an international collaboration across 14 institutions, covered a sky area of 50 square degrees, similar to approximately 250 full moons.

A new study led by the National Institute for Astrophysics (INAF), and with contributions from Radboud University's Marijke Haverkorn, has unveiled significant insights into the Milky Way: a magnetised galactic halo. This discovery challenges previous models of our galaxy's structure and evolution.

Low gravity in space travel found to weaken and disrupt normal rhythm in heart muscle cells New research from Johns Hopkins Medicine scientists find that heart tissues aboard the space station beat about half as strong as on Earth Johns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues and disrupted their normal rhythmic beats when compared to earth-bound samples from the same source.

While the result is different from what they hoped, it's also exactly what they thought it should be Science + Technology While the result is different from what they hoped, it's also exactly what they thought it should be Key takeaways Physicists, including core UCLA researchers, have accurately measured the mass of the W boson - more precisely than a previous attempt at measuring the mass - and found that it is consistent with the Standard Model's predictions of 80 357 ± 6 MeV.

UdeM astronomers find a way to measure temperature changes in a star with greater-than-ever precision, a breakthrough that promises to be particularly useful for detecting and studying exoplanets. Étienne Artigau, the UdeM astrophysicist who led the development of an innovative technique that provides precise information on a star's temperature variations.

In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a massive cluster-scale gravitational lens system that will enable researchers to delve deeper into the mysteries of the cosmos, including dark matter and dark energy.

A Durham physicist is part of an international research team that has discovered the biggest pair of black hole jets ever seen in space, spanning 23 million light-years in total length. The jets' size is equivalent to lining up 140 Milky Way galaxies back-to-back. The research was led by the California Institute of Technology (Caltech) and involved scientists at multiple universities, including Dr Roland Timmerman of our Department of Physics.

Astronomers have spotted the biggest pair of black hole jets ever seen, spanning 23 million light-years in total length. That's equivalent to lining up 140 Milky Way galaxies back to back. "This pair is not just the size of a solar system, or a Milky Way; we are talking about 140 Milky Way diameters in total," says Martijn Oei, a Caltech postdoctoral scholar and lead author of a new Nature paper reporting the findings.

An international team, including UNIGE, unveiled the "Neptunian Ridge", an overdensity of Neptunes nestled between the Neptunian Desert and the Neptunian Savanna. Astronomers have uncovered the ''Neptunian Ridge'', a newly identified feature in the distribution of exoplanets. This discovery, led by an international team including members of the University of Geneva, The NCCR PlanetS and the Centro de Astrobiología (CAB), highlights the complex dynamics within the Neptunian Desert, a region with a scarcity of hot Neptunes, and the Neptunian Savanna, where these planets are more commonly found.

New all-sky survey by the MeerKAT radio telescope shows the universe as expected at large distances - unlike previous observations by other telescopes The cosmological principle is the foundation of modern cosmology and has been confirmed many times by observations and computer models. It states that the universe looks the same from every location and in all directions on a large scale.
