An artist's illustration of two stars against a dense, starry background with red and blue nebula clouds. A large, intensely bright white star dominates the left side of the image, while a smaller, vivid blue star glows to its right, suggesting a binary star system.

How can a young blue giant have a white dwarf companion star that’s billions of years older?

A diagram illustrating the outer solar system from an angled top-down perspective. Concentric orbital paths are shown around a central yellow Sun, with Jupiter, Saturn, Uranus, and Neptune labeled at increasing distances. Pluto is shown in yellow text outside Neptune's orbit, and the entire outer region is surrounded by a diffuse haze representing the Kuiper Belt, labeled in white text.

How do planets clear out objects on the other side of their orbit?

A richly detailed telescope image of a star-forming nebula, filled with swirling clouds of blue, orange, and pink gas and dust. Dark pillars of dense dust cut through the center of the image, surrounded by glowing nebular material and hundreds of orange and yellow stars scattered throughout. A bright cluster of young stars illuminates the lower right portion of the image, casting a warm glow against the surrounding gas clouds.
