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 ...

In a new paper published in Nature today, a team of scientists (led by Martin Cordiner from the NASA Goddard Space Flight ...

Plug-in solar systems are an alternative to large, professionally installed rooftop solar. The US regulatory system for utilities wasn't built for plug-and-play solar setups, so it's taking time for ...

Plug-in panels are getting popular—how do we make sure they’re safe? Dozens of US states are considering legislation to allow people to install plug-in solar systems, often called balcony solar. These ...

Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something ...

Some 4.6 billion years ago, when the solar system was born from a vast cloud that collapsed to form the sun and a surrounding disk of whirling gas, no planets yet orbited our star. Back then, besides ...

Even at a glance, the planets in our solar system are wildly diverse. Huge and small, airless and densely packed with atmosphere, they have a wide range of characteristics distinguishing them. But if ...

The sun is at the Reach Museum, where it takes the form of arches overlooking Bateman Island and the Columbia River at the Richland Wye. Eight planets and an asteroid orbit it in a regional solar ...

The standard story of the origin of our solar system has gone like this: 4.6 billion years ago, a giant cloud of dust hung frozen in space. Then the explosion of a nearby star caused part of that dust ...

Explore the story of our solar system’s formation, tracing how a vast cloud of gas and dust collapsed under gravity, collisions, and angular momentum to create a thin, spinning protolanetary disc.

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, ...

If you’ve seen illustrations or models of the solar system, maybe you noticed that all the planets orbit the Sun in more or less the same plane, traveling in the same direction. But what is above and ...
