Will Comet G3 ATLAS perform at perihelion?

What “may” be the best anticipated comet of 2025 is coming right up. Right now, there’s only one comet with real potential to reach naked eye visibility in 2025: Comet C/2024 G3 ATLAS. This comet reaches perihelion at 0.094 Astronomical Units (AU, 8.7 million miles or 14 million kilometers, interior to the orbit of Mercury) […]

Coordinating risk assessments for radiation in outer space

In the next few decades, crewed missions to the moon and Mars will likely become frequent. One of the main challenges faced by these future missions will be the need to protect astronauts from the intense radiation of outer space.

Field-level inference: Unlocking the full potential of galaxy maps to explore new physics

Galaxies are not islands in the cosmos. While globally the universe expands—driven by the mysterious “dark energy”—locally, galaxies cluster through gravitational interactions, forming the cosmic web held together by dark matter’s gravity. For cosmologists, galaxies are test particles to study gravity, dark matter and dark energy.

Researchers introduce new ‘filament channel’ function to predict solar eruptions triggered by emerging flux

A study published in The Astrophysical Journal Letters, introduces a newly defined “filament channel” function. This new function provides a novel theoretical foundation for predicting solar eruptions by determining whether new emerging flux (NEF) can trigger instability in solar filaments. The study was led by Prof. Lin Jun from the Yunnan Observatories of the Chinese […]

Astronomers find massive supernova remnant closer than previously thought

An international team of astronomers have investigated a large Galactic supernova remnant designated G278.94+1.35. Results of the study, published Dec. 30 on the pre-print server arXiv, shed more light on the properties of this remnant.

Physicists explain a stellar stream’s distinctive features

Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky Way, known for its long, thin structure, and unusual spur and gap features.

Relativistic electron beam could propel probe to Alpha Centauri, study suggests

Getting a spacecraft to another star is a monumental challenge. However, that doesn’t stop people from working on it. The most visible groups currently doing so are Breakthrough Starshot and the Tau Zero Foundation, both of whom focus on a very particular type of propulsion-beamed power.

Fast radio burst confirmed to originate from neutron star

Fast radio bursts (FRBs) are notoriously difficult to study. They are flashes of radio light that can outshine a galaxy but often last for only a fraction of a second. For years, all we could do was observe them by random chance and wonder about their origins.

Video: See and hear three years of solar fireworks

At the start of this new year, we look back at close-up pictures and solar flare data recorded by the ESA-led Solar Orbiter mission over the last three years. See and hear for yourself how the number of flares and their intensity increase, a clear sign of the sun approaching the peak of the 11-year […]
