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...

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...

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.

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.

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.

Australia's Massive Wildfires Widened Ozone Hole, Finds Study
The smoke triggered by the wildfires went to heights of upto 30 kilometres, where the smoke triggered chemical reactions harming atmospheric ozone.

Ozone Layer Is Slowly Recovering, Expected To Be Healed Completely In Decades: UN Report
The scientists hope that if the current trends are followed, the ozone layer is expected to recover to 1980 levels by the year 2040.

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.

Ozone Hole Grows Over Antarctica, But No Cause for Alarm: UN
The seasonal hole in the ozone layer over Antarctica has widened to near-record size, the United Nations said Thursday, insisting though that efforts to save the earth's protective shield were still working.

Ozone Depletion by Refrigerators, Automobile ACs Small but Measurable: Nasa Study
The researchers estimated that the common chemical coolants known as hydrofluorocarbons (HFCs) will cause a 0.035 percent decrease in ozone by 2050.
