Earth Had Six Moons in the Past: New Study Reveals

by Rachel Kim โ€“ Technology Editor
written by Rachel Kim โ€“ Technology Editor

Recent astronomical observations have identified two new “mini-moons” orbiting Earth, Kamo’oalewa and 2024 PT5, exhibiting characteristics similar to our own Moon. Kamo’oalewa, discovered in 2016, reflects light in a manner consistent with the Moon’s surface composition, and its silicate-rich rock makeup mirrors that of our natural satellite. This contrasts with typical asteroids, which often possess different mineral and metallic compositions.

The newly discovered mini-moon 2024 PT5 entered Earth’s orbit on August 7,2024,and displays comparable traits. It was previously nicknamed the ‘second moon’ due to its size and proximity to Earth.

Astronomers are collecting data on these objects as they orbit our planet, leading to speculation that they might be fragments of the Moon.The prevailing scientific theory for the Moon’s formation, the ‘giant collision hypothesis,’ posits that the Moon originated from a massive impact between Earth and a Mars-sized planet approximately four billion years ago. This cataclysmic event ejected material from Earth, which eventually coalesced to form the Moon.

If the giant collision hypothesis and the analysis of 2024 PT5’s origins are accurate, it suggests a familial link between our Moon and these newly discovered mini-moons, with Earth acting as the progenitor body.

Dark Dwarfs: New Objects Could Reveal Dark Matter Secrets

by Rachel Kim โ€“ Technology Editor
written by Rachel Kim โ€“ Technology Editor

Scientists Propose “Dark Dwarfs” as Potential Key to Unlocking Dark Matter Mystery

An international team of scientists, spearheaded by a researcher from the University of Hawaiสปi at Mฤnoa, has put forth a novel concept: “dark dwarfs.” These theoretical celestial bodies coudl offer crucial insights into dark matter, one of the universe’s most profound enigmas.

Dark matter, an invisible substance comprising approximately 25% of the universe’s total matter, eludes direct observation as it neither emits nor reflects light. Its presence is inferred solely thru its gravitational influence. Despite extensive research over many decades, the precise nature of dark matter remains unknown.

The proposed theory suggests that dark dwarfs might originate from brown dwarfs – celestial objects described as “failed stars” due to their insufficient mass to sustain the nuclear fusion that powers conventional stars. These brown dwarfs,when situated in regions of high dark matter density,such as the core of the Milky Way galaxy,could capture dark matter particles.

Within these hypothetical dark dwarfs, the captured dark matter particles are theorized to collide and annihilate each other, releasing energy. This energy release, distinct from the nuclear fusion powering stars like our Sun, is believed to sustain the object’s glow over extended periods.

Researchers indicate that a potential identifying characteristic of these dark dwarfs could be the presence of lithium. Unlike in ordinary stars where lithium is rapidly consumed, it is predicted to persist within dark dwarfs, providing a means to differentiate them from brown dwarfs. Advanced astronomical instruments, such as the james Webb Space Telescope, may be capable of detecting dark dwarfs by searching for these unique lithium signatures within the galactic centre.

Jeremy Sakstein, the lead author of the study and an assistant professor in the Department of Physics and Astronomy at the University of Hawaiสปi at Mฤnoa, stated, “Finding dark dwarfs would be an crucial step toward understanding the true nature of dark matter and the fundamental makeup of the universe.” He also highlighted the importance of Hawaiสปi’s extensive history in astronomical research, positioning UH Mฤnoa as a vital center for investigating the universe’s most profound questions.

This research was published in july 2025 in the Journal of Cosmology and Astroparticle Physics. The Department of Physics and Astronomy is part of the College of Natural Sciences at UH Mฤnoa.

Groundwater’s Hidden Role in Reef Health Revealed

New research shows how groundwater profoundly impacts coral reefs. Fresh water from land alters the chemistry and biological activity within these underwater ecosystems. This new understanding is vital for safeguarding delicate marine environments against threats like pollution.

Groundwater’s “Goldilocks” Effect

A recent study by oceanographers at the University of Hawaiสปi at Mฤnoa reveals that groundwater is vital to coral reef health. According to their research, the right amount of freshwater enhances reefs. However, too much can be detrimental. The team’s findings highlight the complex interaction between land and ocean environments.

Submarine groundwater discharge directly affects these ecosystems by modifying seawater acidity. It also impacts how corals develop their skeletons. The researchers discovered that groundwater discharge increased nutrient availability, allowing reefs to flourish. This study, published in Ecological Monographs, provides important insights into land-sea interactions.

โ€œOne idea we hope this research can communicate is the natural role of groundwater in feeding healthy reefs,โ€ said co-author Craig Nelson. โ€œRunoff and springs bring subsidies of nutrients and organic matter that can help reefs thrive, and the complex interplay this work illuminates demonstrates that some reefs are adapted to these inputs.โ€

โ€œSubmarine groundwater discharge is a widespread and underappreciated land-sea connection that delivers terrestrial nutrients and carbon to coastal ecosystems,โ€ explained lead author Nyssa Silbiger. โ€œThis profoundly influences coral reef health by triggering a cascade of chemical and biological changes that alter the cycling of carbon in these ecosystems.โ€

Cascading Effects

The study analyzed two coral reef sites in French Polynesia’s Moorea. Researchers measured water quality factors directly and indirectly affected by groundwater input. These measurements revealed a complex exchange between organisms and the surrounding seawater chemistry, which is crucial for comprehending reef dynamics.

Nutrients from groundwater enhanced both photosynthetic algae and corals, thereby changing seawater acidity. The altered acidity affected how coral skeletons calcified. Globally, coral reefs are experiencing significant decline, with an estimated 14% of the world’s coral lost between 2009 and 2018 (Nature 2021).

Implications for Reef Management

The study’s authors suggest their research emphasizes the significance of keeping groundwater contaminant-free for both land and ocean ecosystems.

โ€œWe show that adding new nutrients to the coastal ocean alters the metabolism of coral reef ecosystems, thereby changing the patterns of uptake and release of carbon,โ€ said Silbiger.

โ€œThese findings are vital for protecting coral reefs across the Pacific from land-based pollution and informing sustainable land management,โ€ said co-author Megan Donahue. Understanding these effects allows prediction of coral reef responses to environmental change, connecting ecosystem ecology to land-based activities.
