The third planet from the Sun, the only world known to harbor life
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.
The government has moved to refund billions of tariffs struck down by the Supreme Court, with ongoing court cases pressuring CBP to expand the refunds to more importers. Phase one refunds are underway, while the timing and scope of broader reliquidation remain under legal scrutiny.
The blue micromoon is visible this Sunday, visible as a calendar blue moon and a micromoon. It will appear about 6% smaller than an average full moon and is not blue in color. Peak fullness is around 6:45 pm local time.
NASA has disclosed new details about a weekend meteor over New England that produced a double sonic boom. The natural object, 5 feet wide and elephant-sized, traveled at roughly 42,000 mph, fragmented about 40 miles above the ground, and released energy equivalent to about 230-300 tons of TNT. The meteor likely landed in Cape Cod Bay, with no ground impact confirmed.
A wave of space-based data-center startups and defense-aligned ventures are racing to deploy orbital computing. Companies plan test satellites, funding rounds, and government programs to scale AI workloads in orbit, while observers caution about the cost, heat management, and regulatory hurdles.
NASA has named Randy Bresnik, Luca Parmitano, Frank Rubio and Andre Douglas as the Artemis III crew for a mid‑2027, two‑week Earth‑orbit test flight to practice docking with prototype lunar landers from Blue Origin and SpaceX. The all‑male selection has drawn online criticism and questions about whether Blue Origin’s May New Glenn explosion will delay the program.
The National Science Foundation has halted plans to remove or descale the Ocean Observatories Initiative, after lawmakers and scientists warned of risks to climate data, weather forecasts and coastal safety. An expert panel will assess future needs while equipment already removed will be redeployed. The move follows bipartisan pressure and a Senate bill to block decommissioning.
Researchers reveal a vast whale graveyard in the southeastern Indian Ocean, extending to depths of 7,000 metres and spanning hundreds of kilometres. The site hosts hundreds of fossil skeletons and five modern whale falls, highlighting a thriving deep-sea ecosystem that feeds on whale carcasses. The findings, published in Nature, deepen understanding of deep-sea life and whale evolution.
SOLAR-1 has passed eight months of testing and now transmits coronal mass ejection images to NOAA within 30 minutes, improving early warnings for solar storms that could disrupt signals and infrastructure.
Bezos has launched Prometheus to build an “artificial general engineer” that could accelerate invention, with funding surpassing $12 billion and 150 employees. He asserts AI will raise productivity and create opportunities, countering fears of widespread job losses. The company is pursuing AI models for engineering, manufacturing and design, while exploring regulation debates.
Global mapping shows arbuscular mycorrhizal fungi link to plant roots and store hundreds of megatons of carbon, revealing their critical role in the Earth’s carbon cycle and the sensitivity of these underground networks to land use.
A seismic event in Mindanao has caused coastal uplift of up to about 2 metres, exposing coral and seagrass as shoreline retreat is observed along the Cotabato Trench. Authorities report multiple aftershocks and ongoing assessments of casualties and damage.
Recent studies show California’s San Andreas and San Jacinto faults are under stress at levels not seen in a millennium, raising the risk of a large, multi-fault rupture. Cajon Pass could act as a bridge or barrier, and preparedness measures are urged as hazard models improve with physics-based simulations.
UNICEF warns that a vast majority of children worldwide are exposed to multiple climate risks—heat, droughts, floods and more—jeopardising health, education and survival; governments must accelerate renewable energy and resilience efforts.
The Vera C. Rubin Observatory has begun the Legacy Survey of Space and Time, a 10-year program that will image the southern sky every few nights. The telescope has started regular operations from its Chilean mountaintop site and is already returning new detections, including thousands of asteroids and transient views such as Comet 3I/ATLAS.
Scientists have found macromolecular carbon in Martian mudstones, suggesting habitable conditions billions of years ago. The carbon could be biogenic or abiotic; samples will return to Earth for definitive testing, with timelines running 2035–2039. This marks multiple robust organic detections across Jezero crater and Gale crater.
NASA and partners are pursuing a high‑risk salvage to boost the Neil Gehrels Swift Observatory into a higher, stable orbit. A Katalyst Space Technologies robot will capture Swift and lift it from 224 miles to about 373 miles, extending its life as solar activity threatens its destruction in October.
The Verge reports SpaceX plans to invest at least $55 billion in a Terafab chip plant in Austin, Texas, with potential expansion to $119 billion. The project aims to supply chips for SpaceX and Tesla, powering AI, robotics, and data centers. Intel is assisting design and fabrication efforts.
A heat dome has pushed temperatures to dangerous levels across the central and eastern United States. Forecasters warn heat indexes could reach 40–46C (104–115F), with nights offering little relief. Emergency measures are under way in several cities as heat threatens the holiday weekend.
Researchers report a lab-made, membrane-bound system called SpudCell that can feed, grow, replicate genetic material, and divide. The work demonstrates a complete cell-like cycle in a synthetic chassis, using viral components for replication and translation, and points toward future modular engineering while acknowledging remaining challenges.
Amazon has reached a milestone with a satellite constellation of over 390 satellites, enabling initial Leo internet service later this year. The launch cadence faces delays from recent rocket setbacks, but the company plans broader coverage as more satellites go online.
NASA has commissioned a high-stakes rescue operation to move the Swift Observatory back to a safer orbit. The Link spacecraft, launched by Katalyst Space Technologies, is en route to attach to Swift and boost its altitude to prevent a fall back to Earth, with September as the target for resuming full operations.
