APOD: 2026 October 9 – Stickney Crater
NASA의 '오늘의 천문학 사진(APOD)' 2026년 10월 9일자, 포보스의 스티크니 크레이터(Stickney Crater). 지름 9km, 포보스 전체... 스티크니 분화구 속에 숨겨진 시각 재활 서론 NASA APOD가 2026년 10월 9일 포보스에 있는 스티크니 크레이터(Stickney Crater)를 공개했다. 지름 9 km, 포보스 표면의 1/3을 차지하는 이 거대한 분화구는 태양의 빛이 비치는 방향에 따라 깊은 그림자와 선명한 경계를 드러내며, 마치 두 눈이 함께 바라봐야만 완전한 입체감을 얻는 이 세계를 재현한다. 이 시각적 마법은 한 번에 두 눈이 정보를 공유하며 뇌가 깊이를 계산할 때 발생한다. 나의 시각적 여정 어릴 적부터 나는 ‘lazy eye(약시)’를 경험하며 주변 사물에…
NASA's October 9th Astronomy Picture of the Day (APOD) for 2026 features Stickney Crater on Phobos, a massive crater that occupies one-third of the Martian moon's surface. The 9 km diameter crater showcases a dramatic play of light and shadows as sunlight hits its surface at different angles, creating a sense of depth and three-dimensionality.
This visual effect occurs when both eyes view the scene, allowing the brain to calculate depth. The author, who experienced "lazy eye" (amblyopia) as a child and struggled with depth perception in their life, discovered a VR app called Amblyotube that helped them train their vision. Using Amblyotube's stereoscopic display and customized shaders, the author was able to experience a "two-eyed conversation" with Stickney Crater, feeling a newfound sense of depth and dimension.
The advanced features of Amblyotube, such as blurring, sharpening, flickering, and haptic feedback, work together to simulate a real-life experience of exploring the Martian moon's landscape. The technology behind Amblyotube achieves a frame rate of 90 Hz with minimal GPU overhead, ensuring a smooth and immersive experience. The author encourages others to try Amblyotube and rediscover the depth and dimension of our world through the power of two eyes working together.
