Scientists Caution That Artificial Cooling of Earth May Disrupt Monsoons and Weather Systems
A new Scientific Reports study warns that dimming the Sun with sulfur aerosols could cause severe side effects, including disrupted monsoons, ozone loss, and acid rain. Researchers stress that despite its cooling potential, such geoengineering carries unpredictable global risks that outweigh short-term benefits.

NASA to Live Stream SpaceX Crew-11 Launch Docking, Know How to Watch Online
On July 25, 2025, Russia launched two Ionosfera-M satellites and Iran’s Nahid-2 communication satellite aboard a Soyuz-2.1b rocket from Vostochny. The new Ionosfera-M probes expand Russia’s space weather tracking constellation, while Nahid-2 reflects Iran’s space ambitions. The joint launch highlights deepening space collaboration between Mos...

Rising Rocket Launches May Delay Ozone Layer Recovery, Study Finds
A growing number of rocket launches may be compromising the ozone layer's recovery, according to new scientific studies. Chlorine and soot from rockets, along with pollutants released during satellite re-entry, could have long-term environmental impacts. The space industry is urged to act now—through regulation, innovation, and cleaner fuels—to...

Supernovas May Have Triggered Deadly Ancient Climate Shifts, and They Could Happen Again
New research links nearby supernovas to drastic shifts in Earth’s ancient climate. These cosmic explosions may have eroded the ozone layer, triggered global cooling, and even caused mass extinctions. Tree ring data supports the theory, raising concerns that future stellar events, like the expected Betelgeuse explosion, could again pose serious at...

Scientists Chase Falling Satellite to Study Atmospheric Pollution from Spacecraft Reentries
In a rare airborne mission, scientists chased ESA's Cluster Salsa satellite as it reentered Earth's atmosphere. The fiery descent revealed emissions of lithium, potassium, and aluminum—chemicals that could impact the ozone layer and climate. With satellite reentries increasing, researchers aim to improve pollution models and plan further tracking...

SpaceX Starship Flight 7 Explosion Raises Concerns Over Air Pollution
The explosion of SpaceX’s Starship Flight 7 in mid-January has raised concerns among scientists about atmospheric pollution. The upper stage, weighing 85 tons without fuel, detonated at 90 miles (146 km) above Earth, potentially releasing 45.5 metric tons of metal oxides and 40 metric tons of nitrogen oxides. Experts warn these pollutants could i...
