The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

In an incredible breakthrough, a team of international astronomers have for the first time ever witnessed the birth of a planetary system beyond Earth's sun that could one day resemble our own. The ...

Astronomers have gotten an unprecedented view of the bottom of the Sun. On Wednesday, the European Space Agency shared images that show, in all its tumultuous glory, our star’s secretive south pole.

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.

CAPE CANAVERAL, Fla. (AP) — The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another star. US-Russian crew of 3 starts 8-month mission ...

A new planetary system is forming around the young star HOPS-315. Scientists observed the earliest stages of planet formation around another star. The process involves the cooling and solidifying of ...

Hubble has taken the clearest image to date of the interstellar comet 3I/ATLAS, which is racing through our solar system at 130,000 miles per hour. Astronomers are using Hubble and other telescopes to ...

"It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today." Astronomers have discovered a massive new solar system body located ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

This image provided by NASA/European Space Agency shows an image captured by Hubble of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. (NASA/European ...
