An international team of scientists has produced the clearest three-dimensional view yet of the Ring Nebula - one of the night sky's most iconic celestial objects. The Ring Nebula is perhaps one of the most photographed objects in the night sky, dating back to its first image in 1886, but its intrinsic structure has been debated for as long as it has been observed.

The size and spin of black holes can reveal important information about how and where they formed, according to new research. The study, led by scientists at Cardiff University, tests the idea that many of the black holes observed by astronomers have merged multiple times within densely populated environments containing millions of stars.

Life on Earth could not exist without carbon. But carbon itself could not exist without stars. Nearly all'elements except hydrogen and helium - including carbon, oxygen and iron - only exist because they were forged in stellar furnaces and later flung into the cosmos when their stars died. In an ultimate act of galactic recycling, planets like ours are formed by incorporating these star-built atoms into their makeup, be it the iron in Earth's core, the oxygen in its atmosphere or the carbon in the bodies of Earthlings.

Researchers link mysterious cosmic signals to collapsed stars
McGill-led research team's findings point to neutron stars as the probable source of fast radio bursts, one of the universe's most perplexing phenomena An international team of scientists led by McGill researchers has provided the clearest evidence yet that some fast radio bursts (FRBs) - enigmatic, millisecond-long flashes of radio waves from space - originate from neutron stars, the ultra-dense remnants of massive stars that have exploded in a supernova.

The fleeting cosmic firework likely emerged from the turbulent magnetosphere around a far-off neutron star. Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes. These fleeting fireworks last for just a thousandth of a second and can carry an enormous amount of energy - enough to briefly outshine entire galaxies.

The missing ingredient for cooking up stars has been spotted for the first time by an international team led by astronomers at Imperial College. Much like a pressure cooker has a weight on top of its lid to keep the pressure in and get your festive dessert dense, moist and ready to eat, merging galaxies may need magnetic fields to create the ideal conditions for star formation.

NASA's Dawn spacecraft captured this image of Vesta as it left the giant asteroid's orbit in 2012. The framing camera was looking down at the north pole, which is in the middle of the image. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA" Known as flow formations, these channels could be etched on bodies that would seem inhospitable to liquid because they are exposed to the extreme vacuum conditions of space.

Origins of Lunar Water and Its Connection to Earth’s Early History
A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-Moon system and the broader solar system. The pioneering study explores the isotopic signatures of lunar water, revealing a mix of indigenous and cometary sources.

A binary star system at the center of the Milky Way provides new clues as to how stars form around the central black hole An international research team led by Florian Peißker has for the first time found a binary star in the immediate vicinity of the supermassive black hole Sagittarus A* at the center of our galaxy.

The Moon is much older than previously thought. Its crust was reheated after its formation - and has thus misled researchers in determining its age After its formation, the Moon may have been the scene of such immense volcanic activity that its entire crust melted several times and was completely churned through.

2024 Year in Review
As 2024 draws to a close, we look back at some of the Caltech-led discoveries and innovations from throughout the past year. This research extends our understanding of the natural world, enhances researchers ability to probe ever further the mysteries of the universe, and advances new technologies and approaches aimed at diagnosing and treating diseases, building a more sustainable world, and harnessing technologies to benefit society.

New observations with the James Webb Space Telescope no longer rule out the presence of an atmosphere around the Earth-sized rocky planet. However, a geologically active planet also explains the data. Recent measurements with the James Webb Space Telescope (JWST) cast doubt on the current understanding of the exoplanet Trappist-1 b-s nature.

Measuring greenhouse gas with satellites
HFC-125 is a greenhouse gas becoming a major contributor to global warming, and in the first study to use satellites to measure its concentration in the atmosphere, researchers found it has increased exponentially in the past 20 years. The Atmospheric Chemistry Experiment, a research group at the University of Waterloo, and under contract with the Canadian Space Agency, is the first to measure from space the atmospheric concentration of HFC-125, a hydrofluorocarbon (HFC) commonly found in fire extinguishers and commercial cooling systems.

Researchers help uncover rare gamma-ray flare from a distant black hole
A high-energy gamma-ray flare from the super-massive black hole in the Messier 87 (M87) galaxy was observed in 2018 for the first time in nearly a decade, thanks to an international effort involving McGill researchers. This discovery has yielded important insights into the physics of black hole jets, which are among the most efficient engines for distributing energy from the inside of a galaxy to the expanse of the Universe.

Space mission "BepiColombo" delivers data from the innermost planet in our solar system for the first time On December 1, 2024, the BepiColombo mission flew past Mercury for the fifth time and has now become the first spacecraft to observe the surface in the mid-infrared using the MERTIS ("Mercury Radiometer and Thermal Infrared Spectrometer") infrared spectrometer.

Webb telescope's largest study of universe expansion confirms challenge to cosmic theory The findings offer a crucial cross-check for previous Hubble Space Telescope measurements of the universe's mysterious expansion New observations from the James Webb Space Telescope suggest that a new feature in the universe-not a flaw in telescope measurements-may be behind the decadelong mystery of why the universe is expanding faster today than it did in its infancy billions of years ago.

This artist's concept shows interstellar object 1I/2017 U1 ('Oumuamua) after its discovery in 2017. While itself not a dark comet, 'Oumuamua's motion through the solar system has helped researchers better understand the nature of the 14 dark comets di. Credit: European Southern Observatory / M. Kornmesser" These celestial objects look like asteroids but act like comets now come in two flavors.

Smallest asteroids ever detected in the main belt
The team's detection method, which identified 138 space rocks ranging from busto stadium-sized, could aid in tracking potential asteroid impactors. The asteroid that extinguished the dinosaurs is estimated to have been about 10 kilometers across. That's about as wide as Brooklyn, New York. Such a massive impactor is predicted to hit Earth rarely, once every 100 million to 500 million years.
