An artist's impression of an asteroid moving through spaceNASA/JPL-CaltechAsteroid 2024 YR4 recently made headlines after NASA estimated a 1-in-32 chance of impact in 2032—the highest probability ever recorded for a hazardous-sized asteroid. Fortunately, new observations have since cut that risk in half.Discovered in late December, the asteroid passed Earth at roughly twice the Moon’s...

Illustration of cosmic rays striking Earth's magnetic fieldESAHydrogel is commonly found in everyday items like contact lenses, burn dressings, and hair gel. In the future, it could also serve as a protective barrier against harmful cosmic radiation for astronauts on long-duration space missions.Radiation exposure is a significant risk in space travel. Beyond Earth's atmosphere,...
Topaz Labs claims its diffusion model for enhancing footage delivers "the highest visual quality difference ever achievable in video"Topaz LabsTopaz Labs, known for its advanced photo and video enhancement software, has unveiled a new AI model that automatically restores old footage, whether from personal home videos or aging archival content stored on traditional media.In...
In 1927, physicists gathered to discuss the recent formulation of quantum mechanics, at the Solvay Conference on Physics in Brussels. Many important figures were in attendance, including Werner Heisenberg (back row, third from right) and Erwin Schrödinger (back row, sixth from right.) Albert Einstein is front row center.Pictorial Press Ltd./Alamy Stock PhotoA century ago,...
Credit: DepositphotosThe issue of space debris has been growing for years, exacerbated by the continuous launch of rockets and payloads. In recent years, organizations, particularly the European Space Agency (ESA), have begun to take the issue more seriously. Now, they are asking: How can we achieve zero space debris?The Scale and Danger of Space...
The new fuel could pave the way for future nuclear rocket enginesGeneral AtomicsGeneral Atomics Electromagnetic Systems (GA-EMS) has successfully tested nuclear fuel designed for future spacecraft propulsion and power. The tests confirm the fuel's ability to endure the extreme conditions of a nuclear rocket reactor.Until now, spacecraft have primarily relied on chemical rockets for...
Previous AMOC studies relied on sea surface temperature data. A CTD rosette device measures the ocean’s conductivity, temperature, and depth by collecting water samples at varying depths, makingmodels more accurate than ever.
