Earth is dominating headlines as Arctic warming speeds up and NASA’s Artemis II crew returns from a lunar flyby, while Mexico City sinks. Quick bio: Earth, 3rd planet from the Sun, home to life.
On March 3, 2026, a total lunar eclipse, known as a blood moon, was visible across the Americas, eastern Asia, and Australia, turning the moon a copper-red as it passed through Earth's shadow. The eclipse lasted about 5.5 hours with totality near one hour. The UK missed the eclipse due to moonset timing. Additionally, a rare six-planet alignment occurred around February 28 and March 1, visible to the naked eye in many regions.
Recent studies confirm that global warming has accelerated significantly since 2015, with the Earth heating at about 0.35°C per decade—nearly double the previous rate. February 2026 saw extreme rainfall and flooding in Western Europe, while Arctic sea ice reached its third-lowest extent on record. Compound heat and drought extremes are rising rapidly, increasing risks of flash droughts and ecosystem tipping points.
Multiple sources report a rare geomagnetic storm causing the Aurora Borealis to be visible as far south as Norfolk, UK, on March 21, 2026. Forecasters expect the lights to be visible again tonight, driven by recent solar activity and coronal mass ejections, with optimal viewing conditions in dark, clear skies.
Scientists are training divers to explore beneath Arctic ice to better understand climate change impacts. Recent dives reveal fragile ecosystems, while Arctic sea ice levels hit near-record lows, highlighting rapid warming. These efforts aim to inform global climate policies amid accelerating ice melt.
On April 6, 2026, NASA's Artemis II mission flew four astronauts—three Americans and one Canadian—around the Moon, reaching within 4,067 miles of its surface. The crew captured high-resolution images, including Earthrise and a total solar eclipse, transmitted back to Earth via an optical link. The mission tests Orion spacecraft systems ahead of planned lunar landings and aims to establish a sustainable Moon presence.
The Artemis II crew has completed a 10-day mission, traveling further from Earth than any humans have before. They have safely splashed down off California, with their Orion capsule enduring extreme reentry temperatures. The mission confirms the spacecraft's systems and paves the way for future lunar landings.
The NOIRLab has released a detailed image of the sombrero galaxy, revealing its extensive stellar halo and star streams from past collisions. Meanwhile, astronomers have observed interstellar comet C/2025 R3 Pan-STARRS, which is passing through the solar system for the first time in 170,000 years, and the upcoming Lyrid meteor shower is expected to peak tonight, offering spectacular skywatching opportunities.
The Artemis II crew has completed a nearly 10-day lunar flyby, breaking Apollo 13's distance record and returning safely to Earth on April 10, 2026. The mission has tested NASA's Orion spacecraft, provided critical data for Artemis III's planned moon landing in 2027, and energized plans for a sustainable lunar base. The astronauts have shared their experiences and undergone medical checks at NASA's Johnson Space Center.
Earth Day marks six decades of environmental effort, with a global movement highlighting activism, policy gains, and individual action. This year's theme, Our Power, Our Planet, emphasizes small, everyday steps alongside landmark rulings and campaigns that protect ecosystems and curb pollution.
NASA’s NISAR satellite has detected rapid subsidence in Mexico City, showing central areas sinking up to 0.78 inches per month and about 9.5 inches per year. Areas like the main airport and Angel of Independence are among the fastest sinking zones, driven by groundwater pumping and urban growth; researchers say mapping rates is key to mitigation.
