At a budget press conference, Mayor Zohran Mamdani said he backed down from increasing the headcount; he estimated cost of the increase would have been $70 million
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
Chicago Police Superintendent Larry Snelling joined the police department in 1992 as a patrol officer, before later serving as the department’s counterterrorism chief
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that could help search for axions, hypothetical particles that many physicists think could make up dark matter.
Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint radiation themselves. This radiation has not yet been observed in space; instead, researchers use models in the laboratory that mimic the behavior of black holes.
NSF–DOE Vera C. Rubin Observatory has officially begun full operations for the Legacy Survey of Space and Time (LSST), one of the world’s largest astronomical imaging surveys. Behind the scenes, Japanese researchers and engineers are drawing on technologies and expertise cultivated through the development and operation of the Subaru Telescope to support the project’s software, systems and operations. More than 80 researchers from Japan are already participating in LSST science through access to its data. Looking ahead, the combination of Rubin’s wide-area survey and the Subaru Telescope’s detailed follow-up observations will help advance our understanding of fundamental mysteries of the universe.
Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star’s habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75% of the planet’s surface, life is abundant. But what about the exoplanet’s star, specifically its activity and rotation? How could this influence how exoplanets are identified for current and future missions?
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through the solar corona, the outer atmosphere of the sun. The discovery potentially rewrites how scientists understand why the corona is millions of degrees hotter than the surface of the sun itself.
Trooper Michael Pahira, a nearly 20-year law enforcement, was assisting with a commercial vehicle inspection when he was fatally struck by an out-of-control truck
After more than a minute of a physical altercation over the gun, the man appeared to break away with the gun before the Oak Park Police officer fired multiple shots
Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can’t be directly imaged yet, so astronomers must get creative in how they search for signs of life, also called biosignatures. Presently, powerful ground- and space-based telescopes like the Atacama Large Millimeter Array (ALMA) and NASA’s James Webb Space Telescope (JWST) are improving in their ability to observe and analyze exoplanet atmospheres. But how did these atmospheres form and evolve, and what could this mean for the search for life beyond Earth?
For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound microlensing world is a super-Jupiter orbiting far from its host star.
Imagine a piece of space debris the size of a hockey puck slams into a Starlink satellite at about 10 kilometers per second. The kinetic energy is equivalent to 2 kilograms of TNT, or a fully loaded semitruck traveling at 100 kilometers an hour.
Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.
