White Dwarf Gobbles Up Nitrogen-Rich Ices of Pluto-Like World
Astronomers have observed a white dwarf, a highly compact stellar ember, that appears to have gobbled up an icy world akin to dwarf planet Pluto, a finding with implications regarding the likelihood of habitable planets beyond our solar system

Hubble Spots White Dwarf Devouring Icy Pluto-Like Planet 260 Light-Years Away
Using Hubble’s ultraviolet spectrograph, scientists detected carbon, nitrogen, sulphur, and abundant oxygen falling onto a white dwarf 260 light-years away, evidence of an icy planetesimal being torn apart. The find shows volatile worlds can persist into a star’s final stages, offering a preview of the Sun’s distant fate.

NASA Data Shows Pluto’s Equator Is Lined with Towering Methane Ice Spires
New research based on New Horizons’ decade-old data has uncovered extensive bladed terrain made of methane ice on Pluto. These towering spires, arranged in spaced-out, parallel rows, are likely shaped by seasonal condensation and sublimation cycles. While the terrain spans over half the planet’s midsection, five times the width of continental U...

Young Exoplanet Spotted Shedding Atmosphere Under Stellar Radiation
NASA’s Chandra X-ray Observatory and Hubble Space Telescope have captured a dramatic cosmic event: a baby exoplanet, TOI 1227 b, is being stripped of its atmosphere by powerful X-rays from its host star. Only 8 million years old and orbiting a red dwarf, this Jupiter-sized planet is losing gas at a rate equal to Earth’s entire atmosphere every ...

JWST Reveals Pluto’s Haze Cools Atmosphere, Paints Charon’s Poles Red
Pluto's thin haze of organic particles, confirmed by JWST’s mid-infrared observations, plays a crucial role in both cooling its mesosphere and launching methane into space. This methane escapes Pluto’s gravity, landing on Charon’s poles where radiation transforms it into reddish tholins. The study highlights how Pluto’s haze shapes not only...

Discovery Of Small Star Giving Birth To Huge Planet Leaves Scientists Puzzled
TOI-6894 is roughly 240 light-years from Earth in the constellation Leo and is the smallest-known star to host a large planet.

New Dwarf Planet Discovery Challenges Planet Nine Hypothesis
The discovery of a potential dwarf planet, 2017 OF201, in the farthest reaches of the solar system is reshaping our understanding of space. With a highly elongated orbit and large size, it contradicts the Planet Nine hypothesis, which predicted orbital clustering among distant objects. This finding not only questions the existence of a ninth planet...

Scientists Discover New Dwarf Planet Challenging Planet Nine Theory
A US-based trio hunting this elusive world has stumbled on what appears to be a new dwarf planet in the solar system's outer reaches.

Strange Planet Confirmed in Binary Star System Nu Octantis
Astronomers have confirmed the existence of a massive planet in the Nu Octantis binary star system, first suspected in 2004. Using advanced tools like the HARPS spectrograph, researchers found that the planet orbits in the opposite direction of one of the stars—a retrograde motion that keeps the system stable. The discovery of a white dwarf in th...

New Dwarf Planet Discovered Beyond Pluto, Hinting At Hidden 'Planet X'
The discovery of 2017 OF201 is significant, as it challenges the hypothesis of Planet Nine, a hypothetical planet thought to exist in the outer Solar System.

Astronomers Detect Methane in the Atmosphere of the Nearest T Dwarf Star to Earth
Astronomers have detected methane in the nearest known T dwarf, offering new insight into its atmospheric composition. The study further highlights that the carbon abundance in the planet is estimated to be -1.5 dex, while the effective temperature could be around 1,000 K. The author of the paper further revealed that the low metallicity of the T ...
