Astrophotographer Captures ISS Transit Against Solar Flare in Arizona

On June 30, 2025, astrophotographer Andrew McCarthy captured a stunning image of the International Space Station (ISS) transiting in front of the Sun while solar flares erupted in the background. This remarkable photograph was taken from the Sonoran Desert in Arizona, where McCarthy had set up camp to seize this once-in-a-lifetime opportunity. As he documented on his Instagram, McCarthy reported that while he awaited the ISS's transit, a group of sunspots began to flare, leading to the stunning visual. He named the photograph "Kardashev Dreams" in homage to Soviet astronomer Nikolai Kardashev, who devised the Kardashev scale for measuring a civilization's technological advancement.

Describing the challenging conditions, McCarthy noted that the temperature reached 121°F, prompting him to use ice packs and thermoelectric coolers to prevent his telescopes and computers from overheating. His effort yielded what he considers "the most detailed solar transit photo" he has ever taken. The image highlights the tiny ISS as a black silhouette against the Sun's bright yellow-orange surface, illustrating the vast scale of both celestial bodies. The photograph garnered significant attention on social media, with users praising its composition and suggesting it deserves awards. Comments from viewers expressed excitement, with phrases like "that’s an absolutely insane shot" and inquiries about voting for potential awards. This photograph not only showcases McCarthy's skill but also emphasizes the intersection of art and science in capturing the beauty of our universe.
