13,000-Year-Old Cosmic Airburst Triggered ‘Impact Winter’ and Mass Extinction, Research Suggests
New research points to fragments of a comet exploding over North America approximately 13,000 years ago, sparking firestorms and rapid cooling that could have contributed to the extinction of mammoths. Scientists report finding telltale “shocked” quartz grains at classic Clovis sites dating to the Younger Dryas boundary, evidence of intense he...

New Study Models How Interstellar Objects Could Approach and Impact Earth
A new study simulating billions of hypothetical interstellar objects finds that potential Earth-crossing bodies would most likely arrive from the solar apex and the galactic plane. The research highlights relative approach patterns rather than predicting real impacts. Scientists emphasise that known visitors like ‘Oumuamua and Borisov pose no dan...

Devil Comet’s Water Matches Earth, Strengthening Theory of Cosmic Origins
Astronomers discovered that the water in Comet 12P/Pons-Brooks, known as the “Devil Comet,” is nearly identical to Earth’s. Using ALMA and IRTF data, they mapped cometary water for the first time. The findings bolster the theory that comets delivered water to Earth, enabling life’s emergence.

Space Research Reveals How Icy Comets and Asteroids Could Reshape Earth-Like Planets
New scientific models and telescope observations from 2024 and 2025 reveal how comet and asteroid impacts can change atmospheres on Earth-like exoplanets, potentially supporting life or triggering climate disruption.

Comet ATLAS Offers Stunning Display as It Nears the Sun
Comet C/2024 G3 (ATLAS) recently passed within 8 million miles of the Sun, capturing the attention of astronomers. Observed by NASA and ESA’s Solar and Heliospheric Observatory (SOHO), the comet’s tail extended dramatically as it encountered intense solar winds, providing a unique opportunity to study the Sun’s impact on comets. The event, wh...

Meteoroid Trails Could Help Detect Potentially Hazardous Comets Years in Advance
Meteoroid trails from long-period comets could provide early warnings of potentially dangerous comets near Earth, giving planetary scientists time to prepare. By studying these trails, scientists can track the paths of rarely visible comets that could pose a risk of impact, helping prevent catastrophic events. With the upcoming Vera C. Rubin Observ...

Taurid Meteor Stream Unlikely to Contain Dangerous Asteroids, New Study Suggests
A recent study led by Quanzhi Ye, an astronomer at the University of Maryland, reveals that the Taurid Meteoroid Complex, a debris stream linked to past Earth impacts, poses less danger than previously thought. Ye's team found fewer large asteroids in the stream, reducing the risk of a catastrophic collision with Earth. While these findings offer r...

Will There Be A 'Deep Impact'? What Scientists Say On Approaching "Devil Comet"
The comet has got the unique name because of horn-like structures on the comet due to two explosions.

Comet From Edge Of Solar System Killed Dinosaurs: Study
Sixty-six million years ago, a huge celestial object struck off the coast of what is now Mexico, triggering a catastrophic "impact winter" that eventually wiped out three-quarters of life on Earth, including the dinosaurs.

Chandrayaan-2: ISRO Releases Pictures of Impact Craters on Moon
ISRO has released fresh set of pictures of impact craters on moon surface taken by its Chandrayaan-2 Orbiter.

Comet Impact Led To Ancient Global Warming Event: Study
A comet strike may have triggered the rapid warming of Earth caused by an accumulation of atmospheric carbon dioxide 56 million years ago, which offers analogs to global warming today, researchers have found.

Rosetta Crash-Lands on Comet, Ending 12-Year Space Mission
The craft had been programmed for a "controlled impact", at a human walking pace of about 90cm per second.

Comet Craters Helped Create 'Seeds Of Life' On Earth
Large meteorite and comet impacts into the sea may have formed the nurseries from which life on Earth first sparked, a new study has found.

Comet Craters Helped Create Conditions for Life on Earth: Study
According to the researchers, impact craters were ideal environments to facilitate the reactions that saw the first "seeds of life" take root.

Jupiter Doesn't Shield Earth From Comet Impacts: Study
Jupiter's most important role in fostering the development of life may have been just the opposite - delivering the volatile materials from the outer Solar System needed for life to form on Earth.
