The Sun, along with more than 1,500 other stars, journeyed from the middle of the Milky Way to its current position a few billion years ago.

Astronomers already know how planetary systems are born and how they look once they are fully grown, but what has remained mostly hidden is the awkward “teenage” phase in between — the period when ...

Researchers have proposed that changes in Earth's ionosphere could trigger electrical forces that nudge fragile areas of the crust into creating an earthquake. When you purchase through links on our ...

Avoid power surge solar panels damage by not using microinverters, grounding your system, and installing multiple whole-building surge protection devices. Welcome to our series answering reader ...

WASHINGTON — 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 ...

A rare green glow is rising in the night sky. A massive comet packed with carbon dioxide is sweeping through the inner solar system for what scientists believe may be the first and last time. And ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the third known interstellar comet ever spotted. When scientists turned NASA’s ...

As next-generation telescopes map this outer frontier, astronomers are bracing for discoveries that could reveal hidden planets, strange structures, and clues to the solar system’s chaotic youth. Out ...

An intense solar flare erupted from a spot on the sun on Sunday, triggering radio blackouts across the South Pacific Ocean—and now scientists are warning of geomagnetic storms in the coming days. The ...

A new artificial intelligence system has learned to anticipate major changes on the Sun by reading patterns in its surface and atmosphere before they erupt into full storms. That advance reframes how ...

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 ...
