A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

Dust from asteroid Bennu is revealing a surprising origin story for life’s building blocks. New research suggests some amino acids formed in frozen ice exposed to radiation, not warm liquid water as ...

In A Nutshell Ancient frozen chemistry: New analysis of pristine samples from asteroid Bennu suggests its amino acids formed ...

Tiny grains of dust from asteroid Bennu are reshaping how scientists think life’s ingredients formed in space.

Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an ...

Close-up observations of the Sun explain how solar flares start, grow, and send high-energy particles racing through space.

Discover how portable solar chargers, solar leaf chargers, and solar power banks make everyday renewable energy gadgets practical for phones, travel, and emergencies with clear, objective guidance.

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 ...

HELSINKI — China has published coordinated papers outlining dual missions to the solar system’s edge, suggesting the long-studied project is nearing formal approval. A lead paper on the design and key ...

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 ...

It may not feel like it, but everything in the universe is in constant motion. Our Sun, with all its planets, orbits the center of the Milky Way, flying through the cosmos at around 450,000 miles per ...
