In fact, it's so far that astronomers aren't entirely sure if it even belongs to this planetary system.
|
|
"It's hard to conceive in theory of a planetary system better suited for James Webb than TRAPPIST-1."

|
It could be a Neptune mass planet that was captured by a super-Jupiter planet during the formation of the planetary system.
|
|
That means they're like tiny time capsules, providing snapshots of what materials lurked about when our planetary system first came into being.
|
|
When our planetary system formed, the larger planets likely flung trillions of small objects at the system's edge out into interstellar space.
|

But this world was found using a "direct imaging" technique, which lets scientists literally "take a picture of a planetary system and study the light emerging from an exoplanet independent of its host star," Johnson said.
|

Due to the way light spreads as it travels—called diffraction—the laser beam would spread to encompass entire solar systems after journeying many light years across space, bathing that distant planetary system within the cloaking beam.
|
|
Independence Day may have become popularly associated with hostile alien takeovers of Earth, but on Monday, Juno will reverse the trope by peacefully representing Earthlings at a foreign planetary system, without even one city-destroying death ray.

|
Although the first exoplanets had only been discovered a few years before Spitzer was launched, it quickly revealed our first glimpse of the weather on alien planets, revealing circling winds and hotspots, and helped uncover four new planets around TRAPPIST-1, making it the biggest known planetary system outside our own.
|
|
"Understanding the causes of the differences between the Trojans will provide unique and critical knowledge of planetary origins, the source of volatiles [chemicals like nitrogen, water, carbon dioxide and hydrogen] and organics on the terrestrial planets, and the evolution of the planetary system as a whole," said Catherine Olkin, the mission's deputy principal investigator.
|
|
"The destruction of planets could be caused by collisions of planets in a planetary system and/or a planet wandering too close to the star that it orbits—perhaps due to a collision with another body in the system," study co-author Kristina M. Punzi, astrophysics Ph.D. candidate at Rochester Institute of Technology, told Gizmodo.
|
|
The Carnegie Institution explains the significance of this: Only within the last 12 years has it become clear to astronomers that van Maanen's star and other white dwarfs with heavy elements in their spectra represent a type of planetary system featuring vast rings of rocky planetary remnants that deposit debris into the stellar atmosphere.
