Years ago, astronomers believed they had found a planet forming around a nearby star called Fomalhaut. This was very exciting ...

A mystery interstellar object discovered last week is likely to be the oldest comet ever seen—possibly predating our solar system by more than 3 billion years, researchers say. The "water ice-rich" ...

At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of ...

Scientists have captured the first direct images of colliding objects in a neighboring star system. Astronomers have seen the aftermath of two powerful collisions within a 20-year period around a ...

Scientists use acoustic waves and condensed matter physics to detect proteins and cancer cells, sidestepping the limits of ...

A new listing of the 50 most concerning pieces of space debris in low-Earth orbit is dominated by relics more than a quarter-century old, primarily dead rockets left to hurtle through space at the end ...

Humans have been leaving their mark upon Earth for almost as long as we’ve existed. But over the last 70 years — little more than moments in the 300,000-year history of Homo sapiens — the amount of ...

An interstellar object – a comet from a distant star system – is passing through the space between Jupiter and Mars, and according to a recent study, Comet 3I/Atlas may be 3 billion years older than ...

Generative AI and robotics are moving us ever closer to the day when we can ask for an object and have it created within a ...

Active boundary heating and cooling can make a small object look much larger to thermal sensors, a step toward compact ...
