This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA), in ...

Scientists were able to see the moment when planets began to form around a star. Astronomers have witnessed the birth of a solar system beyond our own for the first time. An international team of ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

Scientists at the European Space Agency used a laser to communicate with a spacecraft 165 million miles (265 million kilometers) away in deep space for the first time, marking a major step forward in ...

Solar systems mostly keep to themselves. What's ours is ours and what's not is not. Stars are simply too far from each other—four light years and change to our nearest neighbor—and too big and strong ...

Comets Astronomers are racing to study our solar system's newest 'interstellar visitor.' Here's why. Comets Interstellar comet 3I/ATLAS transforms into a giant 'cosmic rainbow' in trippy new telescope ...

An interstellar object has been spotted zipping through our solar system, and amateur and professional astronomers around the world are now racing to train their telescopes in its direction, allowing ...

On May 21, the International Astronomical Union’s Minor Planet Center announced the discovery of 2017 OF 201, which, because of its distance beyond Neptune, is classified as a trans-Neptunian object ...

In the early days of our solar system, when the Sun was still young and the planets were barely formed, Jupiter wasn’t the gas giant we see today. In fact, today’s Jupiter would look like a midget in ...

Understanding Jupiter's early evolution helps illuminate the broader story of how our solar system developed its distinct structure. Jupiter's gravity, often called the "architect" of our solar system ...

TRI-CITIES, Wash., - A new educational project is set to transform the trails along the Columbia River into a scale model of the solar system. Concrete was recently poured around ten basalt slabs, and ...
