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.

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...

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 ...

T Corona Borealis May Erupt Soon: Rare Nova Could Be Visible to Naked Eye
T Corona Borealis, a binary star system in the Northern Crown constellation, is showing signs of an imminent nova eruption. The white dwarf star, which pulls material from its red giant companion, last erupted in 1946. Astronomers have detected patterns similar to previous eruptions, leading to predictions of a possible outburst within the next two...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

T Coronae Borealis' Nova Outburst May Happen Soon, Experts Suggest
Astronomers are closely monitoring T Coronae Borealis, a binary star system in the Corona Borealis constellation, for its next nova eruption. The event, expected within months, could light up the night sky as the white dwarf gathers material from its red giant companion, triggering a nuclear explosion. Advanced telescopes like NASA’s Fermi are ga...

Exoplanet Orbiting a White Dwarf Star Gives Researchers Hope That Earth Might Escape Its Eventual Death
A planetary system anchored by a white dwarf star, located approximately 4,000 light-years away, provides astronomers with insights into what could happen to our Sun and Earth in about 8 billion years. This scenario unfolds if the Earth survives the Sun's transformation into a red giant, expected to occur in 5 to 6 billion years.
