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...

Elon Musk's Starlink Satellites Could Deplete Earth's Ozone Layer, Study Warns
The ozone layer in the Earth's atmosphere absorbs harmful ultraviolet radiation from the Sun, which can cause skin cancer on exposure and even disrupt crop yields and food production.

Ozone-Harming Gases In Atmosphere Declining Faster Than Expected: Study
Scientists said Tuesday that international efforts to protect the ozone layer had been a "huge global success" after revealing that damaging gases in the atmosphere were declining faster than expected.

Antarctic Wildlife Is Being Sunburnt. Scientists Say It's A "Wake-Up Call"
The ultraviolet radiation from the Sun increase the risk of skin cancer and cataracts in humans, but researchers do not yet know if the same is true for Antarctic mammals and birds.

A Cosmic Blast "Temporarily Destroyed" Some Of Earth's Ozone Layer In 2022: Scientists
In a mind-boggling discovery, scientists have found that a supernova explosion billions of light years away was so powerful that it "temporarily destroyed" some of the Earth's ozone layer in 2022.

Scientists Discover Year-Round Ozone Hole Over Tropics, May Lead to Increased Ground-Level UV Radiation
Scientists have discovered an ozone hole in the earth’s lower stratosphere that is comparable in depth — but seven times larger — to the springtime Antarctic ozone hole. The large, all-season ozone hole has been detected over the tropics, which make up half of the Earth's surface area and are home to about half the planet’s population. The ...

Ancient Microbes May Help in Search for Life on Other Planets, Claims New Study
A team of scientists have reconstructed the condition in which the earliest organism on Earth must have existed. The reconstruction was done using light-capturing proteins in living microbes. In future studies, the scientists hoped to resurrect model rhodopsins in a laboratory using synthetic biology techniques.
