Interstellar Comet 3I/ATLAS experienced a dramatic increase in activity after its closest approach to the Sun, with all types of ice sublimating and releasing organic molecules like water, carbon dioxide, and hydrocarbons. This suggests a unique formation history and composition.
MySat is a fully functional small satellite (CubeSat) STEM kit for space fans. It allows users to build, program, and operate a real satellite system on the ground, providing hands-on experience with space technology.
The interstellar comet 3I/Atlas, only the third confirmed interstellar object ever detected, is being closely observed by spacecraft like Juice and Hubble as it approaches the Sun and Earth.
A fungus found in the Chernobyl exclusion zone, Cladosporium sphaerospermum, appears to thrive in high radiation environments, potentially harnessing ionizing radiation in a way similar to photosynthesis (radiosynthesis). While the exact mechanism remains a mystery, research suggests its melanin may play a key role in both energy conversion and radiation shielding.
NASA’s OSIRIS-REx mission has discovered tryptophan, an essential amino acid, on asteroid Bennu, providing further evidence that asteroids may have delivered building blocks for life to Earth.
An analysis of why building datacenters in space, particularly for AI workloads, is impractical due to challenges with power, thermal regulation, radiation tolerance, and communications.
NASA confirms that 3I/ATLAS is an interstellar comet, dismissing speculation about alien origins. The agency shared images and data from multiple space missions to support this conclusion.
A hyperspectral camera has enabled the first precise measurement of blue auroral nitrogen ion (N₂⁺) emission altitudes during twilight, revealing a peak intensity at about 200 km—higher than previously known. This new method improves altitude estimation and supports models suggesting significant high-altitude N2+ presence.
Comet 3I/ATLAS reached perihelion on October 30, 2025. This article details the findings from observations of this interstellar comet, including its composition, activity, and orbital behavior, and how this data will inform future missions.
Scientists, including those at the SETI Institute, observed the comet and gathered data on its origin, composition, and trajectory.
Key findings include an unusual prevalence of carbon dioxide over water ice, a nickel-to-iron ratio differing from Solar System comets, and a brightening event near perihelion
Thpe data collected will be valuable for future missions like ESA’s Comet Interceptor, preparing scientists to study future interstellar visitors. The article highlights the role of citizen scientists through the Unistellar Network in contributing to these observations.
