The arXiv limit
Putting my community service hat on, I thought I would relay an announcement on the an announcement on the arXiv blog that it is introducing a limit on the rate that any individual can submit papers to arXiv. To start with, the limit will be two per month. This limit applies to the submitter, not to all the authors, so I think large collaborations will find a way around it by having different co-authors do the submissions.
![Captured by the Artemis II crew during their lunar flyby on April 6, 2026, this image shows the Moon fully eclipsing the Sun. From the crew’s perspective, the Moon appears large enough to completely block the Sun, creating nearly 54 minutes of totality and extending the view far beyond what is possible from Earth. The corona forms a glowing halo around the dark lunar disk, revealing details of the Sun’s outer atmosphere typically hidden by its brightness. Also visible are stars, typically too faint to see when imaging the Moon, but with the Moon in darkness stars are readily imaged. This unique vantage point provides both a striking visual and a valuable opportunity for astronauts to document and describe the corona during humanity’s return to deep space. The faint glow of the nearside of the Moon is visible in this image, having been illuminated by light reflected off the Earth.
