Earth's Orbit and Tilt Linked to Ice Age Cycles, Next One Delayed by Climate Change
Scientists have discovered a strong link between Earth's tilt and past ice ages, predicting the next glacial period would have started in 11,000 years. However, rising greenhouse gas emissions are disrupting these natural cycles. The research, based on ocean sediment data, supports the theory that Earth's obliquity governs ice expansion while prece...

May 2024 Solar Storm Triggers Unusual Radiation Belts, Raising Space Safety Concerns
A significant solar storm in May 2024 led to the creation of two temporary radiation belts, detected by the CIRBE satellite in June. One belt contained high-energy electrons, while the other was rich in protons, a rare occurrence. While the electron belt dissipated in three months, the proton-dominated belt remains, potentially affecting space miss...

Time Moves Faster on The Moon Than on Earth, Claims New Study
A 56-microsecond daily time drift between Earth and the Moon, caused by relativity, presents unique challenges for future lunar missions. Scientists are devising a standard lunar time system to ensure navigation accuracy and mission safety, particularly as NASA’s Artemis programme expands human and robotic activity on the Moon. This groundwork is...

Climate Experts Warn "Ice-Free Arctic Summers Before 2050"
In a stern warning, two climate experts on Wednesday cited scientific studies to assert that human activity is pushing Earth to the brink of a dangerous climate tipping point and immediate action is needed to safeguard humanity's future and protect o

Earth's Wild Animal Population Plummets 60 Per Cent In 44 Years: WWF
"Runaway consumption" has decimated global wildlife, triggered a mass extinction and exhausted Earth's capacity to accommodate humanity's expanding appetites, the global conservation group WWF warned Tuesday. From 1970 to 2014, 60 percent of all animals with a backbone -- fish, birds, amphibians, reptiles and mammals -- were wiped out by human appe...

Hidden Lava Tubes On Moon, Mars Can Serve As Human Habitats
Lava tubes - underground caves created by volcanic activity - could provide protected habitats large enough to house streets or even towns on the Moon and Mars, scientists say.

Human Activity Leading Earth Into New Geological Epoch: Study
The evidence for a new geological epoch which marks the impact of human activity on Earth is now overwhelming, according to a new study.
