Modern fluorescence microscopy can generate images of living cells as stunning to look at as they are informative to study. For techniques like fluorescence lifetime imaging microscopy (FLIM), those images provide a window into cell metabolism, helping scientists study cancer treatment, autoimmune disease and more.
No matter the time or vantage point, from a pre-Neolithic cave to a post-lockdown London high-rise, the predictability of the night sky has always been humanity’s symbol of permanence and reassuring stability.
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces.
A new telescope technology—measuring just 6 millimeters (0.24 inches) in diameter—could improve how future space missions study and monitor the sun while simplifying onboard hardware and reducing costs.
There’s a question at the heart of SETI that doesn’t get nearly enough attention. It isn’t whether aliens exist, and it isn’t whether we have the technology to detect them. It’s a far more practical problem: With a billion stars in our galaxy and finite telescope time, how do you decide which ones to actually listen to?
We’re used to a lot of different natural things falling out of the sky. These can include snow, rain and sometimes even frogs (yes, really). All of these relate to weather phenomena.
A massive underground detector aimed at understanding the mysterious ghost particles in our universe released its first major results on Wednesday.
Damage to the Missouri State Highway Patrol cruiser showed that the suspect had fired multiple shots, including one that flew through the cruiser’s passenger window
Carrollton Police Officer Dustin Krish had served the department since September, 2022; his agency remembered him as “courageous and faithful”
After briefings from police and the FBI, Mayor Katie Wilson said credible security concerns justify activating cameras near Seattle’s stadiums during tournament events
The space between stars may seem like a barren desert, but over the past few decades scientists have been finding all sorts of interesting chemicals in it. From the precursors to proteins to the building blocks of cell membranes, there has been discovery after discovery of new molecules in the giant gas clouds between the stars. Now, a new paper available on the arXiv preprint server details the discovery of the first-ever four-carbon sugar in the interstellar medium (ISM), and it is another brick on the path to understanding how life on Earth first developed.
Astronomers have discovered a “galaxy-killing wind” that may explain why there are far more massive “dead” galaxies than expected in the early universe. This wind, powered by cosmic collisions between galaxies, could quickly blow away all the fuel for new stars, leaving a galaxy on the brink of death and helping to solve one of the biggest mysteries in modern astrophysics.
Quantum computers—systems that process information and perform computations by leveraging the principles of quantum mechanics—could solve some tasks faster and more effectively than classical computers. While some studies have demonstrated the advantages of these computers for specific tasks, ensuring their reliable operation in real-world settings has proved challenging.
Astronomers have revealed distinct differences in atmospheric conditions between the morning and evening transition zones of the ultra-hot gas planet WASP-121 b, which separate day from night, commonly called terminators. This achievement was only possible due to the unmatched sensitivity of the James Webb Space Telescope (JWST).
Italian astronaut Luca Parmitano is hoping to bring a taste of his homeland to the Artemis III mission, which he will pilot near Earth in 2027 to test two lunar modules.
