The new is becoming more visible! Comet C/2025 R2 (SWAN) - confirmed in September 2025 in images from the SOHO spacecraft’s SWAN camera - is now up to around magnitude 5.9. That's slightly brighter than it's been. And it's within reach of ordinary binoculars, especially under dark skies. Plus, you might also be able to pick the comet up in long-exposure photographs.

Surprise! An M flare flashed off the sun’s eastern limb (edge). This is the first M flare in about a week, and it signals a new sunspot region that will rotate into view soon. We’ll keep watch, as it rotates into view and earns its new sunspot number. Read the sun news: https://earthsky.org/sun/sun-news-activity-solar-flare-cme-aurora-updates/

🆕 This is one of the deepest views ever obtained of the Universe.

This NASA/ESA/CSA James Webb Space Telescope image revisits one of the most iconic regions of the sky, the Hubble Space Telescope Ultra Deep Field, through the eyes of two of Webb’s instruments. The result is a detailed view that reveals thousands of distant galaxies, some dating back to the earliest periods of cosmic history.

The field shown here, known as the MIRI Deep Imaging Survey (MIDIS) region, included Webb's longest observation of an extragalactic field in one filter so far.
