Imagine a planet like Jupiter zipping around its host star every day and a half, superheated to temperatures hotter than most stars and sporting a giant, glowing gas tail like a comet.That is what an ...
A newly discovered Jupiter-like world is so hot that it’s stretching the definition of the word “planet.”With a day-side temperature of 4,600 Kelvin (more than 7,800 degrees Fahrenheit), planet KELT-9...

The search for planets beyond our solar system is about to gain some new recruits.Today, a team that includes MIT and is led by the Carnegie Institution for Science has released the largest collection...
Imagine living on an exoplanet with two suns. One, you orbit and the other is a very bright, nearby neighbor looming large in your sky. With this “second sun” in the sky, nightfall might be a rare eve...

The Orion Nebula is home to hundreds of young stars and even younger protostars known as proplyds. Many of these nascent systems will go on to develop planets, while others will have their planet-form...
