@garym6942.bsky.socialThe “second-generation” world, predicted from telescope data, could be the first known planet of its kind, and it may shed light on the future of our own solar system. www.smithsonianmag.com/smart-news/l... via @smithsonianmag.bsky.social #astronomy #astrophysics #science #SciChat
@ioppublishing.bsky.socialA new study shows that our Solar System will fall apart sooner than previously predicted! Researchers now estimate that the outer planets of the Solar System will be thrown into disorder roughly one billion years after the Sun becomes a white dwarf: https://ow.ly/He3l50ZV8ra #Astrophysics #Astronomy
@science.socialVenus transits the Sun in this rare multispectral ultraviolet composite. By blending three UV wavelengths, researchers can analyze solar magnetic activity and planetary atmospheric silhouettes at once. A vital look at solar physics and orbital mechanics. #space #astronomy #astrophysics
@science.socialNGC 6164, the Dragon’s Egg, is a bipolar nebula 4,200 light-years away. Formed by massive star HD 148937, its expanding gas reveals the violent late-stage evolution of high-mass stars and recycled interstellar material.

@science.socialMessier 13, the Great Globular Cluster in Hercules, holds hundreds of thousands of stars 25,000 light-years away. In 1974, it was the target for the iconic Arecibo message to deep space. A true marvel of cosmic history. #space #astronomy #astrophysics
@science.socialThe Multiwavelength Crab: Combining X-ray (Chandra), optical (Hubble), and infrared (Spitzer) data reveals how a pulsar's wind interacts with surrounding gas. This view is key to understanding supernova remnants and particle acceleration. #space #astronomy #astrophysics
@hydezero-message.bsky.socialAn encounter is not a detection. Explore a model study of 24 selected stellar streams: subhalo populations, tidal stripping and velocity kicks. Assumptions and observational limits shape dark matter search design.

@science.socialComet 46P/Wirtanen glowed green in 2018 during a historic flyby. This Jupiter-family comet’s coma shines due to diatomic carbon reacting to solar radiation, offering a rare look at the primitive materials of our solar system.
@science.socialA circumzenithal arc, or "smile in the sky," forms as sunlight refracts through ice crystals in cirrus clouds. These vivid spectra appear only when the sun is below 32.2°, offering insights into upper troposphere ice particles.

@starlife.infoCan we know what the surface of another star looks like?
And if we could image a star of any mass the way we see the Sun, what instrument or composite would you use to get the most visual detail?
@science.socialNGC 4414 is a prime example of a flocculent spiral galaxy, featuring patchy star distribution rather than defined arms. 60M light years away, it helps astronomers measure cosmic expansion via Cepheid variables.
@nasaupdates.bsky.socialWhat's inside an exploded star near our galactic center? This new Chandra X-ray view allowed scientists to map specific elements inside the Sgr A East supernova remnant—including iron, sulfur, argon, and calcium! ⚛️✨ #StellarRemnants #Astrophysics
@science.socialNGC 4945, a Seyfert galaxy 13M light-years away in Centaurus, reveals the link between active black holes and galactic evolution. This edge-on view showcases dust and star formation around its high-energy core. #Astronomy #Astrophysics #NASA #NGC4945
@erc.europa.eu🪐 A planet that may have been born from the ashes of its own star.
Boris Gansicke and team @uni-of-warwick.bsky.social identified the first candidate for a second-generation planet around a white dwarf.
