A review of the DWARF mini Smart Telescope, a portable device designed for astrophotography. The article details its features, performance, and ease of use, comparing it to traditional astrophotography setups and highlighting its potential for both beginners and experienced photographers.
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.
A decades-long search for extraterrestrial intelligence, initially powered by volunteers using their home computers, has yielded 100 intriguing signals that UC Berkeley scientists are now investigating with more powerful telescopes.
Five years after the collapse of the Arecibo Telescope, a radio telescope is back online. The signal is back.
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.
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.

A total solar eclipse will sweep across Australia and New Zealand on July 22, 2028, bringing over five minutes of midday darkness. This article details the path of totality, where and when to view it, and related eclipse information.
Recent findings using AI reveal that Sagittarius A*, the supermassive black hole at the center of the Milky Way, is rotating at near-maximum velocity with its rotation axis pointed directly toward Earth. This discovery, made possible by advanced neural networks and Bayesian statistical approaches, challenges established black hole theories and offers new insights into galactic formation.
