Study Reveals Jupiter's Early Growth Prevented Earth From Being Pulled Into The Sun
The findings of this study were published on October 22 in the journal Science Advances.

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.

One Of The World's Rarest Whales Grows In Population In The Atlantic
One of the rarest whales on the planet has continued an encouraging trend of population growth in the wake of new efforts to protect the giant animals, according to scientists who study them.

Ryugu Samples Reveal Ancient Water Flow on Asteroid for a Billion Years
Microscopic samples from asteroid Ryugu reveal that liquid water once flowed through its parent body long after its formation. The finding, led by University of Tokyo scientists, suggests that such asteroids may have delivered far more water to early Earth than previously thought, offering a new perspective on how our planet’s oceans originated.

Astronomers Detect Hints Of Hidden Earth-Sized Planet Beyond Neptune
Astronomers propose the existence of ‘Planet Y’, a hidden Earth-size planet that may orbit closer than the theorized ‘Planet Nine’. Based on Kuiper Belt object patterns, the study suggests a rocky world influencing orbital tilts. Experts remain divided, but upcoming sky surveys could soon confirm or rule out its existence.

Antarctica Sees Similar Climate Change Effects As Greenland: Study
The planet's warming climate is having effects in Antarctica that increasingly resemble those observed in the Arctic, meaning global sea levels could rise faster that previously predicted, Danish researchers warned.

Diamond 'Super-Earth' May Not Be Quite as Precious as Once Thought, Study Finds
New research challenges the idea that 55 Cancri e, once dubbed a “diamond planet”, is rich in carbon. Re-analysing telescope data, scientists concluded that the host star has a lot more oxygen than originally believed, making the possibility that its planet formed with a carbon-dominant atmosphere less likely.

Could a Planet Exist Without a Host Star? Astronomers Say Rogue Worlds May Roam Freely
Astronomers have discovered that planets can survive without stars, drifting as rogue or hypervelocity worlds. Some are flung into space by black holes, while others are displaced by gas giants. On some of these rogue worlds, the idea goes, there might be oceans beneath icy crusts, where life, at least life at a microbe level, could exist.

Exoplanets Explained: How Astronomers Find Worlds Orbiting Stars Beyond the Sun
Exoplanets are planets orbiting stars outside our solar system, hidden by stellar glare and detected indirectly. Astronomers identify them by tracking star wobbles or dips in brightness during planetary transits. NASA’s Kepler mission revealed thousands, with TESS now expanding the search. These discoveries confirm that planetary systems are abun...

Heatwaves May Age You As Much As Smoking Or Drinking. Here's Why
The study highlights the need to understand the physiological stresses of a warming planet on human health.

Mercury Has Shrunk by Several Kilometers Over Billions of Years, Scientists Report
Mercury’s surface reveals it has been shrinking for billions of years due to cooling and faulting. A new study estimates the planet’s radius has contracted by 2.7–5.6 kilometers, offering the most precise figures yet. The findings sharpen understanding of Mercury’s thermal evolution and could help scientists apply the same techniques to tec...

Meteorite That Crashed Into A Home In The US Is Older Than Earth, Study Finds
The meteorite, which formed 4.56 billion years ago, is approximately 20 million years older than Earth.

James Webb Telescope Detects Potential Gas Giant Exoplanet Just 4 Light-Years Away
Astronomers using JWST have spotted a possible gas giant orbiting Alpha Centauri A, only 4 light-years away. If confirmed, it would be the closest exoplanet to a Sun-like star ever imaged. The discovery could challenge current models of planetary formation in binary systems and open new opportunities for studying nearby worlds.

Scientists Explore Role of Space Radiation in Powering Alien Microbial Life
A new study proposes that life may exist far from sunlight in a “radiolytic habitable zone” deep beneath the icy surfaces of Mars, Europa, and Enceladus. Cosmic rays, which can penetrate rock and ice, break water molecules apart to release hydrogen, oxygen, and energy-rich electrons. These can fuel microbes in subsurface water, much like bacter...

Plastic Pollution Threatens Human Health: Study
Ahead of the UN treaty on plastics, a new report in The Lancet journal on Monday has warned that plastic pollution is an underrecognized threat to the health of both humans and the planet, which must be addressed immediately.
