SA 1107-7626: The Dust-Eating Lone Planet That Defies Star-Ceded Growth
Introduction: A rogue planet that eats dust In the annals of space discovery, some objects fit neatly into established categories, while others challenge them. Since its first identification, the young planet SA 1107-7626 has stood apart. Unlike a typical planet that compounds its mass by circling a star, this lone world drifts in interstellar space,…

Rogue Planet Growth: Explosive Accretion in Space
The extraordinary finding A free-floating, or rogue, planet named Cha 1107-7626 is undergoing an immense growth spurt, pulling in gas and dust from its surrounding disk at roughly six billion metric tons per second. Scientists say this is the highest accretion rate ever measured for a planetary-mass object. The discovery, published in The Astrophysical Journal…

Rogue Planet Accretion Surges Explosively in Space
An international team of astronomers has documented an explosive growth phase in a rogue planet, Cha 1107-7626, a world that wanders interstellar space, unbound to any star. The object is accumulating gas and dust from a surrounding disk at a rate of six billion tonnes per second, the highest accretion rate ever recorded for an…

Rogue Planet Accretion: Explosive Growth Revealed in Space
Rogue Planet Accretion: An Unprecedented Growth Spurt Astronomers have identified an enormous burst of growth in a wandering planet, a rogue world that drifts through interstellar space without a parent star. The object, Cha 1107-7626, is accumulating gas and dust at a staggering rate of about six billion tons per second — the highest accretion…

Fiery Auroras on a Rogue Planet: JWST Reveals SIMP-0136 Weather
A fiery aurora reveals a weather-rich rogue planet In a striking departure from typical planet weather reports, astronomers studying the lone world SIMP-0136 — a rogue planet that orbits nothing but the darkness of interstellar space — have detected Northern Lights–style auroras and a surprisingly dynamic atmosphere. The observations come from the NASA/ESA/CSA James Webb…

Astronomers Stunned by Fiery Auroras on a Starless Rogue Planet SIMP-0136
Astronomers using a space telescope have turned their gaze toward SIMP-0136, a nearby rogue planet without a parent star, and witnessed a spectacle more akin to Earth’s auroras than a typical wanderer in deep space. The exquisite sensitivity of the instruments aboard the James Webb Space Telescope enabled researchers to track minute brightness changes as…

Fiery Auroras Blaze on Rogue Planet SIMP-0136, Spotted by JWST
Introduction: A New View of Exoplanet Weather When space telescopes turn their gaze toward worlds beyond our solar system, they often reveal weather that defies Earthbound intuition. The James Webb Space Telescope, operated through a collaboration of NASA, ESA and CSA, has now provided an exceptionally detailed portrait of SIMP-0136, a hot, free-floating planet wandering…

Rogue Planet Baked by Auroras: JWST Finds a Sunless World
JWST Sights a Rogue Planet Baked by Auroras In a groundbreaking study published in Astronomy & Astrophysics, an international team used the James Webb Space Telescope to scrutinize a rogue planet — an object formed in a stellar system but later ejected into interstellar space. With no nearby sun to illuminate its atmosphere, the planet…

JWST Finds Bizarre Planet Baked by Auroras, Far From Any Sun
A Rogue World Illuminated by Auroras A new study published in Astronomy & Astrophysics reports that the James Webb Space Telescope (JWST) has observed a rogue planet — a planetary-mass world drifting in interstellar space, unbound to any star. Far from any solar heat, this world nonetheless shimmers with auroral light across its upper atmosphere.…

Rogue Planet Auroras Bake a Bizarre World, JWST Finds
Rogue Planet Auroras: A New Kind of Heat Source A recent study published in Astronomy & Astrophysics reports a striking finding: a rogue planet wandering the galaxy—unbound to any star—exhibits auroral emissions so intense they effectively bake parts of its atmosphere. The discovery comes from observations made with the James Webb Space Telescope (JWST) and…
