Ozone Layer On Track To Return To 1980s Levels By Mid-Century: Report
The Earth's protective ozone layer is on track to return to 1980s levels by the middle of this century, with the 2024 Antarctic ozone hole smaller than in recent years, the World Meteorological Organization (WMO) said in a new report.

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...

Space Debris Accumulation in the Stratosphere Threatens Major Environmental Risks
The growing presence of satellite space junk, as more satellites enter Earth's orbit, has raised concerns about environmental impacts. Pollution from burnt-up satellites contributes to changes in atmospheric chemistry, with metals like aluminium potentially harming the ozone layer. Scientists warn that satellite re-entries are contributing to a ris...

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.

Antarctic Ozone Hole Might Fully Recover by 2066, Claims New Study
In 2024, scientists observed a notable reduction in the size of the Antarctic ozone hole, marking it as the seventh-smallest on record. With ongoing efforts to eliminate chlorofluorocarbons (CFCs), experts are optimistic that the ozone layer could fully recover by 2066. Factors contributing to this positive trend include a decrease in harmful chemi...
