instead that the Earth is spherical. Their theories were based on observations such as the curved shadow of the Earth on the moon during a lunar eclipse and the way ships gradually disappear over the horizon. Despite this scientific progress, the Flat...

lunar mission in over 50 years. For the first time in more than half a century, astronauts are preparing to journey toward the Moon. The vehicle meant to carry them, however, is not quite ready. NASA’s towering rocket, designed to send four astronauts...

New simulations reveal the Moon may have formed almost intact within mere hours of a massive collision between Earth and the protoplanet Theia. For decades, the dominant theory of lunar formation has painted a picture of a gradual, messy process: a...

The second visual treat arrives on July 17, when Venus will be positioned near a thin waxing crescent moon. At that time the moon will be about 3.5 days past new and illuminated to roughly 17 percent, producing a narrow arc that stands out in deepening...

astronomer, made significant advancements in telescope technology during the early 17th century. His observations of the moon, planets, and stars revolutionized our understanding of the cosmos. The parallel development of microscopes and telescopes...

New lunar radio missions on the Moon’s far side could reveal the universe’s mysterious cosmic dark ages, long before the first stars and galaxies formed. The far side of the Moon, a rugged expanse defined by ancient impact basins and jagged peaks,...

NASA has entered the final countdown for Artemis II, a historic mission set to carry astronauts around the Moon for the first time in more than 50 years, marking a new era of human space exploration. For the first time in more than half a century, the...

of late‑summer’s most familiar lunar displays, often called the Full Sturgeon Moon. According to The Old Farmer’s Almanac, the Moon reaches exact full illumination at 12:18 a.m. Eastern Time, but the evening of August 27 offers an especially convenient...

light in the early evening, allowing farmers to continue their work long after the sun had dipped below the horizon. The moon’s unique orbital timing during this period causes it to rise shortly after sunset for several consecutive nights, flooding the...

opposite the Sun, it will provide a spectacular sight for those viewing with the naked eye, binoculars, or telescopes. The Moon will reach its moment of full illumination at 12:49 p.m. EDT (16:49 GMT) on September 26. While the precise peak occurs...

R. Kane et al, arXiv) The Tidal Tug-of-War Planetary tides act as a mechanism for transferring angular momentum. On Earth, the Moon’s gravity creates a tidal bulge that pulls on the planet, gradually slowing Earth’s rotation while pushing the Moon...

NASA’s DART spacecraft famously shifted the orbit of an asteroid moon in 2022. New research shows the impact also nudged the entire asteroid system around the Sun, marking the first confirmed human-caused change to a celestial body’s heliocentric...

Space are developing a streamlined lunar spacesuit to ensure the Artemis missions stay on track for a successful return to the Moon. NASA is recalibrating its technical requirements for the next-generation lunar spacesuit, a strategic pivot designed to...

lunar pit that could house a massive cave, offering shelter for future astronauts. NASA is preparing to probe one of the Moon’s most compelling geological mysteries. The agency has officially selected a new scientific mission, dubbed GIMLI (Geophysical...

the Orion spacecraft can drastically enhance its structural integrity during the extreme thermal demands of returning from the Moon. Following a comprehensive review of the Artemis II mission, data confirms that a modified flight trajectory resulted in...

Watch as the Moon passes in front of Jupiter during a rare predawn lunar occultation on October 6, visible to observers across parts of North America. Skywatchers across large swaths of North America are in for a rare celestial display on the morning...

A rare lunar eclipse is coming as the Moon passes through Earth’s shadow. Check when and where you can witness this striking celestial event in the sky. Skywatchers across the Americas, Europe, and Africa are preparing for a striking celestial display...

researchers with vital clues to finally pin down when the event occurred. New Simulations Challenge Long-Held Theories on the Moon’s Violent Origins For decades, the prevailing narrative of the Moon’s birth has centered on a cataclysmic collision...

a smaller output of roughly five meteors per hour, but they are noted for bright fireballs that can stand out even when the Moon is present. This year’s peak coincides with a bright waning‑gibbous Moon, which will suppress the visibility of fainter...

oceans reshape the land. Over time, this activity erases almost all physical evidence of the planet’s earliest history. The Moon is different. It has no flowing water, no plate tectonics, and no thick atmosphere to smooth things over. Once something...
