Could a Supernova Threaten Earth’s Survival? Here's What You Need to Know
Supernova explosions have the potential to harm Earth’s atmosphere, particularly the ozone layer. However, no stars close enough to cause damage are currently identified. The risks are low, but gamma-ray bursts, caused by neutron star mergers, may pose an even greater threat in the future.

Apophis Asteroid Flyby in 2029: Earth's Gravitational May Impact Asteroid's Surface
Asteroid 99942 Apophis, named after the ancient Egyptian god of darkness, is set to pass incredibly close to Earth in 2029, at just 32,000 km. While there is no risk of a collision, scientists are keen to study the asteroid’s interaction with Earth's gravity. Research led by planetary scientist Ronald Ballouz suggests that this flyby may cause si...

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...

Study Warns Melting Arctic Ice Could Disrupt Ocean Currents in Europe
Scientists from UiT The Arctic University of Norway have issued a stark warning regarding the impact of melting Arctic sea ice on global ocean circulation patterns. Their recent study highlights that significant inflows of freshwater from melting sea ice into the Nordic Seas have historically led to dramatic cooling in northern Europe. By analysing...

Research Reveals Three Young Asteroid Families as Main Sources of Earth’s Meteorites
A recent study reveals that three asteroid families—the Karin, Koronis, and Massalia—are responsible for around 70% of the meteorites that land on Earth. These families, formed from past collisions in the main asteroid belt, have a higher number of fragments due to their relatively young age. The findings shed light on the origins of meteorites...

Can Diamond Dust Help Cool Earth? Exploring Costs and Geoengineering Risks
A study by Sandro Vattioni explores using 5 million tons of diamond dust annually to reduce global warming by 1.6ºC. Diamonds outperform sulfur in reflecting sunlight, but the method comes with an enormous price tag—$175 trillion. Despite its potential, experts like Douglas MacMartin question its feasibility due to costs, while others debate the...

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...

Asteroid Apophis May Still Have a Small Chance of Hitting Earth in 2029, Study Reveals
Recent simulations suggest a very small chance that asteroid Apophis could be deflected onto a collision course with Earth before its close approach in 2029. Although current data points to a safe pass, the risk remains, especially if another space object were to strike Apophis. The odds are extremely low, but a final verdict won’t be available u...

6 Dangerous Asteroids On Collision Course With Earth, First One May Hit In October
Asteroid Bennu, discovered in 1999, currently poses the greatest risk of impacting our planet.

ESA Cluster Mission Satellite Successfully Reenters Earth After Spending 24 Years in Space
The European Space Agency (ESA) is concluding the Cluster mission, with the first of four satellites safely reentering Earth's atmosphere. This marks the end of a mission that has provided 24 years of valuable space data. In January, the satellite's orbit was adjusted to ensure its reentry would target an uninhabited area, reducing risks for humans...

Asteroid 2024 RW1 Disintegrates Over Luzon, Detected by NASA and ESA Before Impact
Asteroid 2024 RW1 disintegrated over Luzon Island, Philippines, on 4th September. Detected by NASA’s Catalina Sky Survey just hours before impact, the asteroid posed no risk as it burned up in Earth's atmosphere at a speed of 17.6 km per second. Despite the cloud cover caused by Typhoon Yahi, videos of the event were shared online. NASA, along wi...

Geomagnetic Storms Expected To Hit Earth This Week, Power Grids At Risk
A series of potent solar events is expected to hit Earth, potentially causing significant geomagnetic storms over the next few days, NASA has said.

Humans Have Crossed 7 Of 8 "Planetary Boundaries". What It Means
A team of scientists first introduced the concept "planetary boundaries" almost 15 years ago to identify major Earth systems that were at risk of instability because of human activity.
