Satellite Captures 'Ring of Fire' Eclipse from Space
欧洲空间局的PROBA-2卫星从太空拍摄了2月17日的日环食现象,呈现了独特的“火环”效果。文章还预告了2026年的月全食天文事件。
A satellite captured a recent “ring of fire” eclipse from a stunning new angle. The "ring of fire" solar eclipse on February 17. Just days ago the moon traveled directly between Earth and the sun in what was the first solar eclipse of the year, producing a striking “ring of fire” effect in the sky. Unluckily for many sky-gazers, however, only those in Antarctica, or just off the coast of it, would have seen the full eclipse on February 17.
But now new images from the European Space Agency (ESA) reveal the solar eclipse in all its plasmatic glory thanks to ESA’s PROBA-2 satellite. PROBA-2 is a small satellite that hosts two primary instruments designed to observe the sun and other instruments to study space weather. As the craft orbited our planet, the satellite imaged the eclipse at least four times and captured a “perfect” ring of fire, according to the agency.
Also known as an annular eclipse, the ring of fire effect is created because the moon appears slightly smaller than the sun in the sky. Although the moon passes directly in between Earth and our star during this kind of eclipse, it isn’t close enough to totally block out the sun’s light, leaving a glowing halo. From the prime viewing spot of Concordia Station in Antarctica, the ring was reportedly visible for about two minutes.
The next eclipse of 2026 is a total lunar eclipse beginning on March 3 UTC. Then Earth will cast a shadow on the moon, imbuing it with a red hue. Known as a “blood moon,” the eclipse will be at least partially, if not totally, visible to viewers in Asia, Australia, the Pacific Islands and the Americas.
