  • The moon has been secretly feasting on Earth's atmosphere for billions of years

    A new study reveals that tiny fragments of Earth's atmosphere are transported to and absorbed by the moon via gusts of solar wind and our planet's magnetic field, upending a 20-year-old theory based on NASA's Apollo lunar samples... This surprising case of cosmic cannibalism is thanks to supercharged solar winds and, more importantly, our own planet's magnetic field...Ever since NASA's Apollo missions first returned lunar samples to Earth in the early 1970s, scientists have been puzzled by traces of volatiles -- substances that vaporize at relatively low temperatures, including water, carbon dioxide, helium, argon, and nitrogen -- that they found...
  • Yosemite’s Rare “Firefall” Only Happens Once a Year—Here’s What to Know About This Thrilling Phenomenon

    AFAR Magazine ^ | January 21, 2026 | AFAR Magazine Staff
    Every year from mid- to late February, the setting sun hits Yosemite’s Horsetail Fall along the eastern edge of the soaring El Capitan at just the right angle, creating the illusion that the 1,575-foot waterfall is on fire. This Yosemite National Park phenomenon, aka “firefall,” is ultra-popular, and this year is expected to be even more crowded. For the first time since 2021, park reservations are not required to visit Yosemite during firefall. The past 12 months have been tumultuous for the National Park Service, with a 43-day government shutdown, changing free-entry days, and price increases. Now, its rangers will...
  • Astronomy Picture of the Day - Barred Spiral Galaxy NGC 1365 from Webb

    Explanation: A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That's twice the size of our own barred spiral Milky Way. This sharp image from the James Webb Space Telescope's Mid-Infrared Instrument (MIRI) reveals stunning details of this magnificent spiral in infrared light. Webb's field of view stretches about 60,000 light-years across NGC 1365, exploring the galaxy's core and bright newborn star clusters. The intricate network of dusty filaments and bubbles is created by young stars along spiral arms winding from the galaxy's central bar....

    A solar storm has just impacted Earth that's been one of the strongest in the last 20 years, with an immediate G4 geomagnetic storm starting whilst a S4 radiation was already blasting the Earth with high-energy solar particles. With bulk solar wind velocity greater than 1000 km/s and magnetic field values currently creater than 60 nT, this is a near-Carrington level impact and certainly a historic solar storm. Geophysicist Stefan Burns forecasting this possibility more than a year in advance based on the latest space science and more, and now he reports for you LIVE on the current historic space...

    The asteroid, 2025 MN45, completes a full rotation once every 1.88 minutes, meaning it must have a very high strength to keep itself together. An artist's impression of the asteroid 2025 MN45. NSF–DOE Vera C. Rubin Observatory/NOIRLab/SLAC/AURA/P. Marenfeld ===================================================================== The Vera C. Rubin Observatory has observed a record-breaking ultra-fast-rotating asteroid. The space rock is the fastest-spinning asteroid larger than 500 meters (0.3 miles) to have ever been observed. The asteroid, designated 2025 MN45, completes a full rotation every 1.88 minutes. Announced at the NSF–DOE Vera C. Rubin Observatory First Look event in June 2025, it was one of 1,900 new...
  • Astromony Picture of the Day - NanoSail-D2

    01/02/2026 11:34:40 AM PST · by MtnClimber · 8 replies
    NASA ^ | 2 Jan, 2026 | Image Credit & Copyright: Ralf Vandebergh
    Explanation: In 2011, on January 20, NASA's NanoSail-D2 unfurled a very thin and very reflective 10 square meter sail becoming the first solar sail spacecraft in low Earth orbit. Often considered the stuff of science fiction, sailing through space was suggested 400 years ago by astronomer Johannes Kepler, who had observed comet tails blown by the solar wind. But modern solar sail spacecraft designs, like NanoSail-D2, Japan's interplanetary spacecraft IKAROS, or the Planetary Society's Lightsail A, rely on the small but continuous pressure from sunlight itself for thrust. Glinting in the sunlight as it circled planet Earth, NanoSail-D2's solar sail...

In 46 BC, Julius Caesar, pictured above in a self-decreed minted coin, created a calendar system that added one leap day every four years. Acting on advice by Alexandrian astronomer Sosigenes, Caesar did this to make up for the fact that the Earth's year...

    December 25, 2003, Christmas DayA Message to Earth Apollo 8 lifted off from the Kennedy Space Center on December 21, 1968. It was the first mission to the moon with a crew aboard, and its purpose was to orbit the moon in preparation for a future landing on the moon. On Christmas Eve, Apollo 8 entered lunar orbit and the crew began to relay back to Earth live television pictures of the moon and the Earth. They ended their broadcast by saying: “For all the people on Earth, the crew of Apollo 8 has a message we would like to...

    NASA told them to say something. And so they did. "In the beginning, God created the heaven and the earth. . . .'' The trio of astronauts of Apollo 8, speaking from space on Christmas Eve in 1968, quoted from Genesis, the first book of the Bible. It was, opines historian Robert Zimmerman, "the most profound Christmas prayer ever given by any member of the human race.'' "It was a natural. It's really the basis of most of the world's religions,'' said James Lovell, an Apollo 8 astronaut who has lent the flight manual containing the verses to the Adler...

    The Adler Planetarium has the first Christmas message from space: the 1968 flight manual from Apollo 8 containing verses of Genesis. The three crew members took turns, on live television on Christmas Eve, reading the opening passages of the Bible, starting with, "In the beginning, God created the heaven and the Earth. ..." "It was a natural. It's really the basis of most of the world's religions," Apollo 8 astronaut and Lake Forest restaurateur James Lovell said in an interview last year. Historian Robert Zimmerman, writing in his book Genesis: The First Manned Flight To Another World, called it "the...

    The year 1968 was one of the mst discouraging in modern US history. The Vietnam War dragged on. Despite major civil rights bills, many people feared the country was turning "increasingly seperate and unequal." The nation grieved over the assassinations of Martin Luther King JR. and Robert Kennedy. Riots filled the streets.

    It happened on Christmas Eve, 48 years ago. Three men took turns reading from the first 10 verses of the Book of Genesis. They were nearly 250,000 miles away from Bethlehem, but since it was the night before Christmas, and there was no chimney from which to hang their stockings, the three astronauts inside the Apollo 8 capsule orbiting the moon thought it would be appropriate. So as Jim Lovell,Frank Borman and Bill Anders looked at the faraway Earth through the small window of the spacecraft, they read the verses: “In the beginning, God made the heavens and the Earth.”...
