How big does the Sun actually look from each planet?

This image puts it all in perspective – from the blinding, horizon-filling Sun seen on Mercury to a tiny, brilliant point from Neptune.

☄️Comet A3 has an anti-tail! Can you see it?

▫️Unlike the dust tail, the anti-tail shows the comet's past path, reflecting where it has traveled.

▫️ Dust tail always points away due to solar wind and radiation pressure.

Ring of Fire over Easter Island

Explanation: The second solar eclipse of 2024 began in the Pacific. On October 2nd the Moon's shadow swept from west to east, with an annular eclipse visible along a narrow antumbral shadow path tracking mostly over ocean, making its only major landfall near the southern tip of South America, and then ending in the southern Atlantic. The dramatic total annular eclipse phase is known to some as a ring of fire. Also tracking across islands in the southern Pacific, the Moon's antumbral shadow grazed Easter Island allowing denizens to follow all phases of the annular eclipse. Framed by palm tree leaves this clear island view is a stack of two images, one taken with and one taken without a solar filter near the moment of the maximum annular phase. The New Moon's silhouette appears just off center, though still engulfed by the bright disk of the active Sun.

This analema produced by the Sun by J. C. Casado was posted in National Geographic. It takes a picture every week, at the same time and location for one year, to create this analema.

Stars are born in cold molecular clouds where gas clumps and collapses, forming baby stars called protostars.

🌟 This stunning image from @NASAWebb shows the 'mountains' of NGC 3324, a stellar nursery in the Carina Nebula, where new stars are forming. #JWST #Astronomy

Exoplanet Zoo: Other Stars (APOD: 2024 Jul 08)

Evidence from star wobbles and dimmings shows that over 5,500 exoplanets have been discovered. This illustration guesses their appearance: blue Neptune-types, tan/red Jupiter-types, and variously colored Earth-like planets. As more exoplanets are found, our understanding of Earth-like planets and potential life in the universe grows.
