One night three months ago, Rosa Castro finished her dinner, opened her laptop, and uncovered a novel object that was neither planet nor star.

This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler's first four years of data. It's also the final catalog from the spacecraft's view of the patch of sky in the Cygnus constellation.

A newly discovered Jupiter-like world is so hot, it's being vaporized by its own star.

Many young stars, as well as more middle-aged stars like our sun, have "debris disks"--like the Oort Cloud in our own solar system--that are believed to be remnants of the system's formation.

This image depicts the dusty disc encircling the young, isolated star HD 169142.

The turbulent atmosphere of a hot, gaseous planet known as HD 80606b is shown in this simulation based on data from NASA's Spitzer Space Telescope.

Evidence of planetary debris surrounding a double sun, 'Tatooine-like' system has been found for the first time by a UCL-led team of researchers.

It will be announced tomorrow by NASA that Michael Gillon et al have confirmed 4 more Earth-sized planets circling TRAPPIST-1 in addition to 3 already discovered.

NASA is inviting the public to help search for possible undiscovered worlds in the outer reaches of our solar system and in neighboring interstellar space.

A possible planet in a nearby stellar system may be betraying its presence in a unique way: by a shadow that is sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding a young star.

Sun-like Star Ate Some Of Its Planets

An international team of scientists, including researchers from the University of Chicago, has made the rare discovery of a planetary system with a host star similar to Earth's sun.

A team of scientists and engineers led by Princeton researchers recently reported the successful operation of a new instrument for the Subaru Telescope in Hawaii that will allow astronomers to make direct observations of planets orbiting nearby stars.

Via a NASA-led citizen science project, eight people with no formal training in astrophysics helped discover what could be a fruitful new place to search for planets outside our solar system - a large disk of gas and dust encircling a star known as a circumstellar disk.

A number of extrasolar planets have been found in the past two decades and now researchers agree that planets can have a wide variety of characteristics.

When a star is young, it is often still surrounded by a primordial rotating disk of gas and dust, from which planets can form.

Astronomers have found signs of a growing planet around TW Hydra, a nearby young star, using the Atacama Large Millimeter/submillimeter Array (ALMA).

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third.

Using NASA's Hubble Space Telescope, astronomers have conducted the first search for atmospheres around temperate, Earth-sized planets beyond our solar system and found indications that increase the chances of habitability on two exoplanets.

Astronomers have "cracked" a very cold case with the dissection of light from the coldest known brown dwarf.

If you thought Luke Skywalker's home planet, Tatooine, was a strange world with its two suns in the sky, imagine this: a planet where you'd either experience constant daylight or enjoy triple sunrises and sunsets each day, depending on the seasons, which happen to last longer than human lifetimes.
