Phase-coherent lasers are crucial for many precision tasks, including timekeeping. Here on Earth the most stable optical ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

NASA shared some new infrared images of the 3I/ATLAS interstellar comet this week, showing the visitor brightening up in a dramatic outburst while exiting a solar system. The images were taken by the ...

Every once in a while, the outer solar system reminds us that we've only discovered a negligible portion of it, and that the vast majority is still full of surprises. The latest example of this is a ...

The first few exoplanets were discovered in the early 1990s. But it wasn’t until the early 2000s, when astronomers began carrying out large-scale, long-term surveys of other stars, that we started to ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

Earth has the perfect combination of a livable atmosphere and a protective magnetic field that prevents the Sun's harmful radiation and radioactive solar winds from damaging us, allowing us to live on ...

Nothing manmade has reached further from Earth than the Voyager series of spacecraft. Hurtling away from the sun at 38,000 miles an hour, the duo have now traveled over 12 billion miles, with Voyager ...

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

A new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for ...
