Gerard k. O’neill Was Not Honored as Deserved, so Far… But Maybe It’s Not Too Late!

While doing research during the works of the SRI 4th World Congress, I am trying to deepen my knowledge of the immense work done by Gerard K. O’Neill and his Space Studies Institute (SSI) during the second half of the past century.

Gerry took the work where Tsiolkovsky, Oberth, von Braun, and others had left it, on the great theme of rotating habitats in free space. And more, the SSI, founded by him, has developed an incredible amount of very high-profile studies about space manufacturing [1], covering many aspects of living in free-space habitats. Not only scientific and technical issues. According to the O’Neill teachings—as his main references, like Krafft Ehricke and others, had done—human requirements, attention to life and health protection, human rights, and social needs informed all of the developed studies and conceptual design.

Great outreachers like Isaac Asimov, Arthur Clarke, and Stanley Kubrick were ready to follow O’Neill and promote his concepts in their artworks and in their interviews to TV and media magazines.

Self-regulating process governs cosmic order inside star clusters

A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, the mass of new stars born inside a star cluster is actually governed by a defined process of self-regulation. Their work has been published in the journal Research in Astronomy and Astrophysics.

When a galaxy welcomes new stars, they are usually formed in star clusters inside vast gas clouds. While some of these stars inside such clusters are small, cool and dim, others possess 10 times the mass of our sun and a hundred thousand times higher brightness—but also a shorter lifespan as a result. These differences in initial mass have a significant influence on a galaxy’s luminosity.

“The total mass of a dwarf galaxy is relatively low, so it won’t produce any extremely massive stars that’d be brighter than our sun,” explains Professor Pavel Kroupa from the Helmholtz Institute for Radiation and Nuclear Physics at the University of Bonn. “By contrast, very massive elliptical galaxies, which formed almost 10 billion stars in just 10 million years during the early stage of the universe, generate millions of these ultra-bright stars.”

‘How worlds are created’: University of Washington astronomers find evidence of planets clashing

Anastasios Tzanidakis, a UW doctoral student in astronomy, was looking through data from 2020 when he noticed an otherwise unremarkable star’s light dimming and then fluctuating wildly. What he found was evidence of planets colliding — which could shed light on how planets, like ours, form.

‘Aquila Booster’ challenges theoretical limits of particle acceleration in pulsar wind nebulae

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron and posing a challenge to the classical theory of particle acceleration in pulsar wind nebulae.

This discovery is important because the calculated particle acceleration efficiency of this celestial structure approaches or even exceeds the theoretical limits allowed under ideal magnetohydrodynamic conditions.

This study, published in Nature Astronomy, was conducted by Prof. Liu Ruoyu, Dr. Wang Kai, and doctoral student Tong Chaonan from Nanjing University, Prof. Chen Songzhan and Assoc. Prof. Wang Lingyu from the Institute of High Energy Physics of the Chinese Academy of Sciences, and their collaborators.

Newton’s 300-Year-Old Law Passes Its Biggest Cosmic Test Yet

Gravity may seem simple in everyday life. Drop an apple, and it falls. On cosmic scales, though, gravity becomes one of science’s biggest stress tests. It governs the rise of galaxies, the behavior of galaxy clusters, and the overall architecture of the universe, yet some of the universe’s motions still do not add up.

That long-running mismatch is what drove University of Pennsylvania cosmologist Patricio A. Gallardo and his collaborators to ask a basic but profound question: what if gravity itself behaves differently across the largest distances in the universe?

TESS discovers an Earth-sized planet orbiting nearby M-dwarf star

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation TOI-4616 b, is slightly larger than Earth. The finding was reported in a research paper published March 11 on the arXiv pre-print server.

Launched in 2018, TESS is in the process of scanning about 200,000 of the brightest stars near the sun, searching for potential transiting exoplanets. To date, it has identified more than 7,900 candidate exoplanets (TESS Objects of Interest, or TOI), of which 760 have been confirmed.

Nearby M dwarf draws attention of planet seekers One of the stars observed by TESS is TOI-4616—an M dwarf of spectral type M4 at a distance of some 91.8 light years away from Earth. TESS has identified a transit signal with a period of approximately 1.5 days in the light curve of this star. Now, follow-up observations of TOI-4616 conducted by a group of astronomers led by Francis Zong Lang of the University of Bern, Switzerland, have validated the planetary nature of this transit signal.

Chinese scientists discover rare-earth-rich new lunar minerals in Chang’e-5 mission samples

Chinese scientists have identified two previously unknown lunar minerals from the 1,731 grams of moon samples returned by Chang’e-5 mission, marking another major breakthrough in deep-space research. The findings were announced on Friday at the opening ceremony of the 11th China Space Day. The two newly discovered minerals have been officially approved and classified by the International Mineralogical Association. They are named magnesiochangesite-(Y) and changesite-(Ce).
