SMILE Spacecraft Captures First Full-Day Auroral Oval Since 2008

The joint European-Chinese SMILE spacecraft has successfully captured the first complete ultraviolet images of Earth's auroral oval since 2008. These images, taken during a daytime substorm, reveal the full ring of northern lights around the North Pole, a view previously impossible from the ground. The mission, which launched in May 2026, aims to study how solar wind interacts with Earth's magnetosphere to improve space weather forecasting and protect infrastructure.

SMILE Satellite Begins Science Ops, Capturing Daytime Auroras in First UV Images

The joint European-Chinese SMILE satellite officially began science operations on September 23, 2026, after a successful commissioning phase. Its first ultraviolet images, captured on July 24, reveal auroras visible in broad daylight over the North Pole. The mission aims to study solar wind interactions with Earth's magnetic field, with its X-ray imager currently undergoing calibration to reduce stray light before targeting the magnetopause in mid-October.

SMILE Satellite Captures First Full View of Earth’s Daytime Auroras

The Solar Wind Magnetosphere Ionosphere Link Explorer (SMILE) has released its first ultraviolet images, revealing the full ring of northern lights encircling Earth’s North Pole. Captured on July 24, 2026, the footage shows auroral activity on both the day and night sides of the planet, a capability not seen since 2008. This marks the start of science operations for the joint European-Chinese mission, which aims to improve understanding of solar storms and space weather.

ISRO Video Reveals Aditya L1's SUIT Capturing the Sun in Space

India's Aditya-L1 mission, dedicated to studying the Sun, has successfully captured full-disk images of the star in near ultraviolet wavelengths using the Solar Ultraviolet Imaging Telescope (SUIT) instrument. Developed by the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in collaboration with ISRO, SUIT allows for unprecedented observations of the Sun's lower and middle layers without atmospheric interference. The mission aims to enhance our understanding of the Sun's dynamics and its influence on space weather phenomena, providing insights into the effects of solar radiation on Earth's climate.

Solar Orbiter's Camera Hack Reveals Hidden Depths of the Sun's Atmosphere

Scientists have successfully used a "hack" to modify Solar Orbiter's EUI camera, allowing it to capture high-resolution images of the Sun's atmosphere at extreme ultraviolet wavelengths. By adding a small protruding "thumb" to the camera's safety door, the modified instrument can now see deeper into the Sun's corona, revealing previously unexplored regions. This new mode of operation, known as the occulter mode, has the potential to influence future solar instruments for upcoming missions and offers the opportunity to study the changing magnetic structures and physics in this little-explored region.
