Universe
The universe is everything that exists — space, time, matter, and energy. It is vast, expanding constantly, and contains billions of galaxies, each with countless stars and planets.
Black Hole
A black hole is a region in space where gravity is so strong that nothing, not even light, can escape.
Exoplanets
Exoplanets are planets that orbit stars outside our solar system. Some may have conditions suitable for life, making them an exciting area of research in astronomy.
Stars
Stars are giant balls of hot gases, mainly hydrogen and helium, that produce light and energy through nuclear fusion. They are the building blocks of galaxies and come in different sizes and colors.
Black Hole
A black hole is a region in space where gravity is so strong that nothing, not even light, can escape. A black hole is a region of space with extremely strong gravity.Formed when massive stars collapse after their life cycle.Nothing, not even light, can escape from it.
Stars
Stars are giant balls of hot gases, mainly hydrogen and helium, that produce light and energy through nuclear fusion. They shine due to nuclear fusion, converting hydrogen into helium. They are the building blocks of galaxies and come in different sizes and colors. Stars vary in size, temperature.

Exoplanets are planets that orbit stars outside our solar system. Some may have conditions suitable for life, making them an exciting area of research in astronomy.Some exoplanets are located in the habitable zone, where conditions might allow liquid water and possibly life.

Exoplanets Catalog
This exoplanetary encyclopedia — continuously updated, with more than 5,900 entries — combines interactive 3D models and detailed data on all confirmed exoplanets. When you select a planet’s name, see a visualization of each world and system, along with vital statistics.

The Habitable Zone
The definition of “habitable zone” is the distance from a star at which liquid water could exist on orbiting planets’ surfaces. Habitable zones are also known as “Goldilocks zones,” where conditions might be just right — not too hot, not too cold — for life.
