TRAPPIST-1e Methane Signal Likely False, Webb Data Suggests Airless Planet
The TRAPPIST-1 planetary system, located about 39 light-years from Earth, hosts seven rocky worlds orbiting a cool red dwarf star. While several of these Earth-sized planets lie in the star’s habitable zone, new observations from the James Webb Space Telescope suggest their atmospheres may be too thin to support life. Earlier hints of methane aro...

Astronomers Record First-Ever Massive Stellar Blast Capable Of Stripping Planetary Atmospheres
This event originated from a red dwarf star, which is much dimmer, cooler, and smaller than the Sun.

Astronomers Spot First Coronal Mass Ejection from a Distant Star, Raising Questions About Planetary Habitability
Astronomers detected the first coronal mass ejection from a distant star, revealing that powerful stellar eruptions may strip atmospheres from nearby planets, affecting exoplanet habitability and the search for life.

Newly Found ‘Super-Earth’ GJ 251 c Could Be One of the Most Promising Worlds for Alien Life
A new super-Earth, GJ 251 c, has been found orbiting a nearby red dwarf star within its habitable zone. About four times Earth’s mass, it may host liquid water. Detected via the radial-velocity method using Penn State’s Habitable Zone Planet Finder, it’s a prime target in the search for life.

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.

Dead Star's Supernova Explosion Could Be Visible From Earth During Daytime, Study Predicts
When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems
Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

UY Scuti Reigns as the Universe’s Biggest Known Star, but Its Crown May Be at Risk
UY Scuti, a red hypergiant about 1,700 times the Sun’s radius, is the universe’s largest known star. Nearly 5 billion suns could fit inside its volume, but rivals like NML Cygni and Westerlund 1-26 challenge its claim to the crown. Astronomers stress that size estimates carry large uncertainties, leaving the title of biggest star still conteste...

Ursa Major III May Be a Star Cluster, Not a Dark-Matter Dwarf Galaxy
Astronomers have long thought Ursa Major III, also called UNIONS 1, was a dark-matter-packed dwarf galaxy. But new simulations suggest it may instead be a compact star cluster bound by black holes and neutron stars. Located 30,000 light-years away, Ursa Major III contains just ~60 visible stars yet shows puzzlingly high stellar velocities. The new ...

Hubble Discovers White Dwarf Merger Remnant with Unusual Carbon Signature
An international team of astronomers has discovered WD 0525+526, an unusual white dwarf about 128 light-years away, using NASA’s Hubble Space Telescope. Unlike typical white dwarfs, this star formed through a stellar merger and shows an unexpectedly high carbon content. With a mass of 1.2 Suns and a scorching surface temperature of 21,000 K, the ...

Exoplanet 35 Light-Years Away Offers Hope for Life Beyond Earth
The exoplanet has a minimum mass 2.8 times that of Earth and has been categorised as a super-Earth.

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 ...

Astronomers Capture Planet Birth Around Baby Sun Outside Solar System
Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

NASA’s Hubble and Webb Discover Bursting Star Formation in Small Magellanic Cloud
NASA’s Hubble and Webb telescopes have captured spectacular images of NGC 460 and NGC 456, two star clusters in the Small Magellanic Cloud. These young, open clusters are filled with massive, hot stars that trigger new star formation by carving nebulae. The findings provide insights into early universe conditions and interstellar medium behaviour...
