The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study by an international collaboration led by Penn State astronomers.
An international team of astronomers has successfully demonstrated a new technique to observe especially faint black holes by correcting for atmospheric effects on Earth. The technique, called “frequency phase transfer (FPT),” can now be implemented at observatories participating in the Event Horizon Telescope (EHT), making the global array more sensitive than ever before.
Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The discovery will allow researchers to engineer technologies that make use of the technique to develop applications in fields such as biomedical testing and drug development.
Deputy Daniel V. Chavira, a 2024 academy graduate, came from a family deeply involved in law enforcement, with several relatives actively serving in the LASD
Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results, published in Nature, show that this radiation dampens the wounded galaxy’s ability to form new stars.
When people think of black holes, they imagine something dramatic: a star exploding in space, collapsing in on itself, and forming a cosmic monster that eats everything around it. But what if black holes didn’t always begin with a bang? What if, instead, they started quietly—growing inside stars, which still appear alive from the outside, without anyone noticing?
In recent years, humanity has visited several near-Earth asteroids (NEAs), including Ryugu (Hayabusa2) and Didymos (DART). However, we will need more frequent missions to start gathering more helpful information about this class of over 37,000 space rocks. CubeSats have off-the-shelf components and a relatively small size, making them a potentially good candidate for such an exploration program.
Researchers at the International Center for Radio Astronomy Research (ICRAR) made the discovery about galaxies by studying the gas distribution that helps create stars.
One of the most profound open questions in modern physics is: “Is gravity quantum?” The other fundamental forces—electromagnetic, weak, and strong—have all been successfully described, but no complete and consistent quantum theory of gravity yet exists.
A new camera setup can record three-dimensional movies with a single pixel. Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The Kobe University development thus opens the door to holographic video microscopy.
An international team of astronomers using the Einstein Probe reports the discovery of a new peculiar fast-evolving X-transient. The newfound transient exhibits an unprecedented long-lasting X-ray emission. The finding was detailed in a paper published May 12 on the arXiv preprint server.
Space enthusiasts and families across the U.K. will have the chance to contribute directly to climate science through an upgraded cloud-spotting project launched today.
Scientists studying a promising quantum material have stumbled upon a surprise: within its crystal structure, the material naturally forms one of the world’s thinnest semiconductor junctions—a building block of most modern electronics. The junction is just 3.3 nanometers thick, about 25,000 times thinner than a sheet of paper.
On May 19th, 2005, NASA’s Mars Exploration Rover Spirit captured this stunning view as the sun sank below the rim of Gusev crater on Mars.
