This is an artist's concept of HD 189733b and its parent star.

An animation explaining how the hybrid Lyot coronagraph works. Watch the longer version here.

On this episode of Q&Alien, we talk about what the term "habitable zone" means - and what it doesn't.

Ubicado a menos de 32 años luz de la Tierra, AU Microscopii se encuentra entre los sistemas planetarios más jóvenes jamás observados por los astrónomos, ¡y su estrella tiene unas brutales rabietas!

The first exoplanet directly imaged was 2M1207 b. Itt was also the first planet found orbiting a brown dwarf. A composite image by ESO's VLT (Very Large Telescope) reveals the exoplanet orbiting th...

This artist's concept illustrates the hottest planet yet observed in the Universe. The scorching ball of gas, a "hot Jupiter" called HD 149026b, is about 3 times hotter than the surface of Venus.

¡Esta galaxia escalofriantemente encantada dejó de crear estrellas, de manera misteriosa, solo unos pocos miles de millones de años tras el Big Bang!

This illustration shows three possible scenarios for the evolution of asteroid belts.

A graphic of present and future exoplanet missions from space agencies and observatories around the world.

This artist's conception shows the object named WISE J085510.83-071442.5, the coldest known brown dwarf. Brown dwarfs are dim star-like bodies that lack the mass to burn nuclear fuel as stars do.

There is only one planet we know of so far that is teeming with life–– Earth. If we want to find life on other planets, we start with the ingredients we know at home.

An artist's concept of brilliant auroras on the brown dwarf LSR J1835+3259, a misfit failed star about 18.5 light-years from Earth.

A detailed explanation into the workings of the coronagraph and how it can help directly image exoplanets.

For Valentine's Day, give the tight-knit Kepler-11 to your faves.

Of the more than 1,000 verified planets found by NASA's Kepler Space Telescope, eight are less than twice Earth-size and in their stars' habitable zone. All eight orbit stars cooler and smaller tha...

This artist's concept illustrates how planetary systems arise out of massive collisions between rocky bodies.

This artist's concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface.

Young stars start out with a massive disk of gas and dust that over time, astronomers think, either diffuses away or coalesces into planets and asteroids.

This is an artist's concept of the star HD 3651 as it is orbited by a close-in Saturn-mass planetary companion and the distant brown dwarf companion discovered by Spitzer infrared photographs.

How do coronagraphs find exoplanets? Find out in this animation narrated by Dr. Nick Siegler, Technology Manager of the NASA Exoplanet Exploration Program.

The tightly packed system, named Kepler-444, is home to five small planets in very compact orbits. The planets were detected from the dimming that occurs when they transit the disk of their parent ...

The artist's concept depicts a comet-like tail of a possible disintegrating super Mercury-size planet candidate as it transits its parent star named KIC 12557548.

Like Luke Skywalker's planet "Tatooine" in Star Wars, Kepler-16b orbits a pair of stars. Kepler-16b is a gas giant like Saturn, so it has no solid surface to stand on. The view here is depicted on ...

A truly doomed planet, WASP-12b is being cannibalized by its star.

A unique feature of the seventh Kepler candidate catalog is that it is the first to fully automate the assessment of transit-like signals. The total height of each bar shows the total number of Kep...
