Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF's NOIRLab telescopes, and is designed to be the pre-eminent digital galaxy atlas for large galaxies. It’s a treasure trove of information for researchers investigating everything from galaxy formation and evolution to dark matter and gravitational waves. It’s also freely available online for the public to explore.

Researchers used a combination of methods to measure a reaction where a neutron from a deuterium target is exchanged with a proton from a radioactive projectile, a reaction equivalent to a process in exploding stars.

Within a neighboring dwarf galaxy known as the Small Magellanic Cloud (SMC) lies a dramatic region of star birth – NGC 346, shown here. As the brightest and largest star-forming region in the SMC, it has been studied intensely by a variety of telescopes. NASA’s Hubble Space Telescope showed a visible-light view filled with thousands of stars. More recently, NASA’s James Webb Space Telescope offered a near-infrared vista highlighting both cool and warm dust. Now, Webb has turned its mid-infrared gaze to NGC 346, revealing streamers of gas and dust studded with bright patches filled with young protostars.

Utilizando datos del telescopio Gemini Sur y de otros observatorios, los astrónomos encontraron un nuevo Evento Transitorio Óptico Azul Rápido (LFBOT por sus siglas en inglés), un tipo de poderosa explosión cósmica, de la cual no se sabe mucho. El estallido, al que se le apodó como “el Finch”, ocurrió en las afueras de una galaxia, a diferencia de otros LFBOT descubiertos hasta ahora que se hallaron anidando en galaxias de formación estelar. Esta observación pone en duda las teorías actuales sobre los orígenes de este tipo de eventos transitorios.

Using data from Gemini South and other observatories, astronomers have found a new Luminous Fast Blue Optical Transient (LFBOT), a powerful but poorly understood type of cosmic explosion. However, rather than being nestled in a star-forming galaxy like other LFBOTs discovered so far, the latest event, dubbed ‘the Finch’, occurred in the far outskirts of a galaxy. This observation calls into question leading ideas about the origins of these transient events.

In a groundbreaking study, a team of Georgia Tech researchers has unveiled a remarkable discovery: the identification of novel bacterial proteins that play a vital role in the formation and stability of methane clathrates, which trap gigatons of greenhouse gas beneath the seafloor. These newfound proteins not only suppress methane clathrate growth as effectively as toxic chemicals used in drilling but also prove to be eco-friendly and scalable. This innovative breakthrough not only promises to enhance environmental safety in natural gas transportation but also sheds light on the potential for similar biomolecules to support life beyond Earth.
