4 years after the giant Arecibo Observatory collapsed, we finally know what happened

NeRD

What does the discovery of a binary pulsar in 1974, the discovery of the first exoplanets, and the most powerful message humans have ever sent out into space all have in common? They all happened at the Arecibo Observatory in Puerto Rico. With a spherical reflector dish that was 305 meters (roughly 1000 feet) in diameter, Arecibo held the title of world’s largest radio telescope for over half a century — from its construction in 1963 until 2016. To the dismay of astronomers around the world, in 2020, Arecibo’s reflector…

TIME Recognizes the Advanced Composite Solar Sail System In October, the Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024”! TIME Magazine also recognized two other NASA missions this year: Europa Clipper, and the Deep Space Optical Communications experiment.    The Advanced Composite Solar Sail System is a demonstration of technologies that enable spacecraft to “sail on sunlight,” using solar radiation for propulsion. Results from this mission could provide an alternative to chemical and electric propulsion systems and guide the…

NASA still mum about SpaceX Crew-8 astronaut’s medical issue

NeRD

NASA is not yet ready to tell us why one of its astronauts was hospitalized shortly after returning to Earth last month. That astronaut was one of the four members of SpaceX‘s Crew-8 mission to the International Space Station (ISS), which ended with a splashdown off the coast of Florida on Oct. 25. Everything appeared to go well with the landing. Shortly thereafter, however, all four astronauts — NASA’s Matthew Dominick, Michael Barratt and Jeanette Epps, and Alexander Grebenkin of Russia’s space agency Roscosmos — were taken to a Florida hospital for…

Powerful New US-Indian Satellite Will Track Earth’s Changing Surface

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The NISAR mission will help researchers get a better understanding of how Earth’s surface changes over time, including in the lead-up to volcanic eruptions like the one pictured, at Mount Redoubt in southern Alaska in April 2009. R.G. McGimsey/AVO/USGS Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure. We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and…

Saturn and the moon put on a celestial show Sunday night. Here’s how to see it

NeRD

Saturn gets close to the moon tonight, and skywatchers in Florida, northwestern South America, the Caribbean and Central America will see the ringed planet briefly disappear behind our lunar companion. When a celestial body, such as a moon, planet or an asteroid passes in front of another celestial body, blocking its view, we call that an occultation. The word is derived from the Latin occultäre, to conceal or hide.  Occultations of planets by the moon are fairly rare events for any given location on Earth, but when they do occur,…

Milky Way swirls over famous Easter Island statutes in stunning photo

NeRD

Sometimes a photo can captivate so powerfully that you are transported to another place and time. When photographer Josh Dury traveled to Easter Island for last month’s annular solar eclipse, he wasn’t going to let a single moment go to waste. Although primarily there with a group of expert Astro Trails eclipse chasers for the day-time event, Dury also managed to capture some images overnight, with some of the island’s famous statues, known as Moai. Due to its remote location, Easter Island has one of the darkest skies on Earth.…
