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.

Astronomers Discover New Earth-Sized Planet Orbiting Jupiter-Sized Red Dwarf Star
This new extrasolar planet, or exoplanet, is named Speculoos-3b and is located relatively close to the Earth, just 55 light-years away.

"Fluffiest Planet Ever": Scientists Discover "Marshmallow World" In Deep Space
Scientists are finding all sorts of weird worlds. They've now discovered a gas giant planet with the density of a marshmallow orbiting a cool red dwarf star located 580 light years from Earth. The planet, identified as TOI-3757 b, is the "fluffiest".

Scientists Believe 'Alien' Rock Hypatia May Reveal Details on Events That Lead to Supernova Explosions
Researchers are hopeful that an extraterrestrial stone found in the Egyptian desert could help shed some light on these spectacular events. The stone is named Hypatia. The experts have a hypothesis that the Hypatia stone originated with a star – a red giant star collapsed into a white dwarf star, which eventually “ate” the other star.

Death of a White Dwarf Star Creates Cosmic Red Ribbons of Gas, NASA Shares Photo
In a binary system a white dwarf gravitational pulls matter from its companion and then explodes.

First Giant Exoplanet Found Orbiting Extinguished Star
Astronomers have discovered a planet the size of Jupiter closely orbiting the smouldering remains of a dead star, the first time that an intact exoplanet has been discovered travelling around a white dwarf, according to research published Wednesday.

Nearby Red Dwarf Star 'AD Leonis' With Massive Solar Flares Spotted
Astronomers have captured a red dwarf star called AD Leonis that is found to have massive flares — one of them was even 20 times larger than the solar flares emitted by our own Sun. The star is just 16 light-years away from Earth.

Scientists Discover a New Planet Hidden in a Debris Disk of a Young Star
Astronomers have a found a new exoplanet hiding in the debris disk of a star. Dubbed as AU Mic b, the exoplanet was found after decades of search, around the red dwarf star, AU Microscopii that is roughly 32 light-years away.

Earth-Like Exoplanet Found Orbiting a Sun-Like Star a Little Over 3,000 Light Years Away: Study
Planet KOI-456.04' is thought to be similar to Earth for several reasons. It is said to have a similar distance between its sun - Kepler-160 - with an orbit that takes it 378 days to complete. It also thought to receive 93 percent as much light as Earth gets from the Sun.

Newly Discovered "Super-Earth" May Harbour Alien Life: Report
The recently discovered cold super-Earth exoplanet orbiting around the red dwarf Barnard -- the second closest star system to Earth -- has the potential to harbour primitive life, says a study.

'Super-Earth' Discovered Orbiting Sun's Nearest Star
Astronomers studied Barnard's Star, a red dwarf just six light years away and noticed the presence of a "frozen, dimly lit world" at least 3.2 times heavier than Earth.

This Exoplanet Could Have Rocky Surface, Atmosphere Like Earth
Researchers have found that a little known exoplanet orbiting a red dwarf star located about 111 light years away in the constellation Leo could have a rocky surface and a small gaseous atmosphere -- like Earth.

There's A New Planet In The Neighborhood - And It Looks Like A Nice Place To Live
One of our closest celestial neighbors is a warm, rocky world, scientists say. Writing in the journal Astronomy and Astrophysics, scientists report the discovery of an Earth-size exoplanet orbiting the star Ross 128, a dim red dwarf just 11 light-years away
