There’s a new space telescope in the sky: Euclid. Equipped with two large panoramic cameras, Euclid captures light from the visible to the near-infrared. It took five hours of observing for Euclid’s 1.2-meter diameter primary mirror to capture, through its sharp optics, the 1000+ galaxies in the Perseus cluster, which lies 250 million light years […]
The spiral galaxy IC 342, located about 11 million light-years from Earth, lies behind the crowded plane of the Milky Way: Dust, gas, and stars obscure it from our view. Euclid used its near-infrared instrument to peer through the dust and study it. via NASA https://ift.tt/e6Nr1fs
It moved across the surface of Mars — what was it? A dust devil. Such spinning columns of rising air are heated by the warm surface and are also common in warm and dry areas on planet Earth. Typically lasting only a few minutes, dust devils become visible as they pick up loose red-colored dust, […]

What was that red glow on the horizon last night? Aurora. Our unusually active Sun produced a surface explosion a few days ago that sent out a burst of electrons, protons, and more massive charged nuclei. This coronal mass ejection (CME) triggered auroras here on Earth that are being reported unusually far south in Earth’s […]
It was Halloween and the sky looked like a creature. Exactly which creature, the astrophotographer was unsure (but possibly you can suggest one). Exactly what caused this eerie apparition in 2013 was sure: one of the best auroral displays that year. This spectacular aurora had an unusually high degree of detail. Pictured here, the vivid […]
Last Wednesday the voyaging Lucy spacecraft encountered its first asteroid, 152830 Dinkinesh, and discovered the inner-main belt asteroid has a moon. From a distance of just over 400 kilometers, Lucy’s Long-Range Reconnaissance Imager captured this close-up of the binary system during a flyby at 4.5 kilometer per second or around 10,000 miles per hour. A […]

That bright beacon you’ve seen rising in the east just after sunset is Jupiter. Climbing high in midnight skies, our Solar System’s ruling gas giant was at its 2023 opposition, opposite the Sun in planet Earth’s sky, on November 2. But only a few days earlier, on October 28, the Moon was at its own […]
