Reference Planet Venus will have a flurry of spacecraft visit it in the next few years as scientists seek to learn more about the volcanic, lava-filled planet.
Earth is constantly showered by space rocks, but how many of these actually land on Earth's surface?
Cosmic impacts can make planets and moons more porous than previously thought, potentially boosting their ability to host life, a new study finds.
The soil and water of Mars are normally too harsh for crops, but research led by a then-high schooler finds that alfalfa plants and photosynthetic bacteria might help make conditions fit for farming.
A new model exploring the dwarf planet Ceres suggests radioactivity deep in the small world may have created criss-crossed geology at its surface.
A meteorite on Earth holds new evidence that asteroids do indeed mysteriously spit out pebbles, a new study finds.
Reference Pluto was once considered the ninth planet in the solar system, it was demoted in 2006 to dwarf planet status. We explore this icy body in more detail here.
Reference Jupiter is the biggest planet in the solar system and has 79 moons. Learn more about the gas giant in our ultimate guide.
Scientists have found the Martian birthplace of a 4.5 billion-year-old meteorite, potentially shedding light on the origins of Mars and other rocky worlds.
Reference Mars, the fourth planet from the sun is famed for its rusty red appearance. Here we explore the Red Planet in more detail and see why scientists find it so intriguing.
Liquid water once shaped the rock inside a meteorite from Mars, but likely did not support any microbial life, a new study finds.
New meteorite research suggests that cosmic impacts might have helped deliver vital ingredients of life to ancient Earth.
Reference Learn how stars form, how stars and constellations are named, what happens when stars like our sun evolve, and ultimately, die.
Reference Planet Mercury is the sun's nearest planetary neighbor. It has short years, long days, huge surface temperature fluctuations and really weird sunsets.
The most distant single star seen yet dates back to less than 1 billion years after the universe's birth in the Big Bang, and may shed light on the earliest stars in the cosmos, a new study finds.
Two giant bubbles of gamma rays and X-rays that erupted from the center of the Milky Way may stem from a supermassive black hole's feeding frenzy at the heart of the galaxy, a new study finds.
Miniature spaceships the size of cellphones could fly across the solar system using sails propelled by lasers, reaching distant destinations on very reasonable timescales.
Two dozen so-called superhabitable alien worlds may be as good as or better than Earth for life as we know it.
Neptune is the farthest planet from the sun and was the first to be predicted before it was discovered.
The water that Earth has may have been here since the planet formed, and not delivered later by collisions with icy comets, a new study finds.
Distant X-rays may be the most direct evidence yet of the remains of a disintegrated planet colliding with the corpse of a star, a new study finds.
Astronomers may have for the first time detected and measured the mass of an isolated stellar-mass black hole, a new study finds.
