✨🔭 New observations of #Ganymede 🌖reveal a surprising similarity between the #auroras 🌌 on the #SolarSystem's largest #moon and those on #Earth 🌍. A team of space physicists has obtained new results suggesting that the fundamental physical processes that generate auroras are common to different celestial bodies.

Thanks @Umbertogaetani for sharing 🙏 https://mastodon.uno/@Umbertogaetani/116113873863038999

Using joint observations from the #Tianwen-1 in the #solarwind and #MAVEN in the induced #magnetosphere, Lin et al. identified a magnetic barrier between #Mars’ #ionosphere and shocked solar wind under the radial #IMF for the first time.

Weekly Update from the Open Journal of Astrophysics – 31/01/2026

It’s Saturday once more so time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further three papers, bringing the number in Volume 9 (2026) to 18 and the total so far published by OJAp up to 466.

I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter which nobody should be using; these announcement also show the DOI for each paper.

The first paper to report this week is “Probing Stellar Kinematics with the Time-Asymmetric Hanbury Brown and Twiss Effect” by Lucijana Stanic (University of Zurich, Switzerland) and 13 others based in Zurich, Lausanne and Geneva (all in Switzerland). This was published on Monday 26th January 2026 in the folder Instrumentation and Methods for Astrophysics. This research demonstrates that intensity interferometry can reveal internal stellar kinematics, providing a new way to observe stellar dynamics with high time resolution.

The second paper is “DIPLODOCUS I: Framework for the evaluation of relativistic transport equations with continuous forcing and discrete particle interactions” by Christopher N Everett & Garret Cotter (University of Oxford, UK). This was published on Tuesday January 27th 2026 in the folder High-Energy Astrophysical Phenomena. DIPLODOCUS is a new framework for mesoscopic modelling of astrophysical systems, using an integral formulation of relativistic transport equations and a discretisation procedure for particle distributions.

Next, also published on Tuesday January 27th but in the folder Cosmology and Nongalactic Astrophysics we have “The Atacama Cosmology Telescope: DR6 Sunyaev-Zel’dovich Selected Galaxy Clusters Catalog” by M. Aguena et al. (101 authors altogether), on behalf of the ACT-DES-HSC Collaboration. This article reports on the discovery of 10,040 galaxy clusters in the Atacama Cosmology Telescope data, including 1,180 clusters at high redshifts, using the Sunyaev-Zel’dovich effect.

And finally for this week we have a paper published yesterday, Friday 30th January 2026, in the folder Astrophysics of Galaxies. This is the paper I blogged about yesterday: “A Cosmic Miracle: A Remarkably Luminous Galaxy at zspec = 14.44 Confirmed with JWST” by Rohan Naidu (MIT Kavli Institute) and an international cast of 45 others. This article reports on the discovery by the James Webb Space Telescope (JWST) of a bright galaxy, MoM-z14, located 280 million years post-Big Bang, that challenges models of galaxy formation and the star-formation history of early galaxies.

And that concludes the update for this week. I will do another next Saturday.

Vera Chernogorova – Conversations About The Atomic Nucleus (Eureka Series)

The book discusses issues related to the study of the atomic nucleus and its structure, nuclear forces, and the components of the nucleus. It also describes the achievements of Soviet scientists in the field of nuclear energy.

About the Author

After graduating from the Faculty of Physics and Mathematics at university, Vera Aleksandrovna entered postgraduate studies and later became a research fellow at the Joint Institute for Nuclear Research in the town of Dubna. For nearly twelve years, she participated in experiments conducted on a particle accelerator — the synchrocyclotron. Vera Aleksandrovna is a co-author of many scientifi c papers on the study of the properties of mu-mesons.

In recent years, she has published over ten articles in journals such as Znanie — Sila (Knowledge Is Power), Science and Life, Technology for the Youth, and others.

The topics of these articles include problems in nuclear physics, high-energy physics, astrophysics, controlled thermonuclear fusion, the application of scientific achievements in The human practice, and the future of science. Many of these articles have been reprinted in foreign journals.

In 1973, our publishing house released her book Mysteries of the Microworld, which discussed some current problems in the physics of elementary particles. Conversations About the Atomic Nucleus is the author’s second book to appear in the Eureka series.
