Laser Interferometer Lunar Antenna (LILA): Advancing the U.S. Priorities in Gravitational-wave and Lunar Science Very proud of our new paper out today. An early tribute to the 10th anniversary of the historic discovery of gravitational waves. arxiv.org/abs/2508.11631

A reminder to our media friends that 100% of the Apollo material released today has been public for decades. The "shocking" audio "released" from Apollo 17 is literally in a Daft Punk song. The document below is from the Apollo 11 technical crew debriefing, made public in 1977.

When they were orbiting the moon, the Apollo 11 astronauts saw a strange cylinder-shaped object fly by them. From today's DOD release.

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

Hello, Moon. It’s great to be back. Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: nasa.gov/artemis-ii-mul…

One last look at Earth before we reach the Moon. This view of the Earth was captured on April 5, the fourth day of the Artemis II mission, from inside the Orion spacecraft. The four astronauts will reach their closest approach of the Moon tomorrow, April 6.

To build a sustained human presence on the Moon, we are building @NASAMoonBase, prioritizing surface operations and scalable infrastructure.  - Frequent robotic landings and mobility testing including MoonFall drones  - Starting in 2027 nearly monthly cadence of equipment and rovers with scientific payloads landing on the Moon.  - Investments in power, communications, and surface mobility  - Scalable infrastructure to support long-term human presence The objective is clear: build the foundation for an enduring lunar base and take the next step toward Mars.

Yann LeCun
Yann LeCun@ylecun·
Hugo Duminil-Copin, French mathematician and 2022 Field Medalist told me he never participated in math competition and was very bad at it. Innovative mathematics requires creativity, intuition, intense concentration, and long reflections, sometimes spread over several years. Good performance at a math olympiad merely tests fast problem solving abilities. AI can do that nowadays. One of the big activities of a researcher, in mathematics and elsewhere, is not to answer questions but to ask the right questions.

Large language models and audio transformers are known for mastering human speech and tackling complex tasks. But can they learn the grammar of spacetime (gravitational waves) and the elusive ragas of black holes? I’m excited to share my lab’s latest breakthrough, now published in The Astrophysical Journal Letters (@AAS_Office), where we adapted OpenAI's audio transformer to analyze gravitational-wave data from a rare black hole and learn signal structure directly from spacetime itself. By treating gravitational-wave data like an audio “language,” we applied our in-house machine-learning architecture to listen directly to @LIGO data. We found that GW231123 is indeed a rare “Lite” intermediate-mass black hole merger whose signals show hint of some unaccounted physics. More broadly, this work demonstrates how foundation models developed for human communication can be repurposed to probe the laws of nature. This marks the beginning of a new era of gaining deep insights into the General Theory of Relativity with AI. Big kudos to my team led by Dr. Chayan Chatterjee, PhD students Kaylah McGowan, Suyash Deshmukh, and master's student Nicholas-Tyler Howard for this breakthrough work.

2025 has been one of the most satisfying and productive academic year. All credit to my amazing group of students and postdocs @VanderbiltU, collaborators from across the gravitational-wave spectrum (LILA, LIGO, LISA) and new partners in lunar geoscience.

@demishassabis Perhaps on a similar spectrum to chess, how our brain has evolved to do mathematics that transcend any evolutionary needs, especially by the likes of Ramanujan, is as great a mystery as the origin of spacetime itself.

Yann is just plain incorrect here, he’s confusing general intelligence with universal intelligence. Brains are the most exquis​ite and complex phenomena we know of in the universe (so far), and they are in fact extremely general. Obviously one can’t circumvent the no free lunch theorem so in a practical and finite system there always has to be some degree of specialisation around the ​target distribution that is being learnt. But the point about generality is that in theory, in the Turing Machine sense​, the architecture of ​s​uch a general system is capable of learning anything computable given enough time and memory​ (and data), and the human brain (and AI foundation models) are approximate Turing Machines. Finally, with ​regards to ​Yann's comments about chess players, it’s amazing that humans could have invented chess ​in the first place (and all the other ​a​spects ​o​f modern civilization ​from science to 747s!) let alone get as brilliant at it as someone like Magnus. He may not be ​strictly optimal (after all he has finite memory and limited time to make a decision) but it’s incredible what he and we can do with our brains given they were evolved for hunter gathering.
Haider.@haider1

Yann LeCun says there is no such thing as general intelligence Human intelligence is super-specialized for the physical world, and our feeling of generality is an illusion We only seem general because we can't imagine the problems we're blind to "the concept is complete BS"

When we start to go offworld - in a serious way - whether it is rocky and/or icy worlds (lunar south pole) - we'll need to be able to do things like this. Trying it out on a Hoth-analog in #antarctica is a good start. @NSF @NASA @uw_icecube @rookisaacman #Artemis

🎥 Here is a 7-hour time-lapse at the start of drilling the first hole for the IceCube Upgrade. This comes almost exactly 15 years after drilling for the 86th hole of IceCube was finished on December 18, 2010! 🤯 🎥 Jennifer Wang and Vedant Basu, IceCube/NSF
