India’s pioneering solar observatory, Aditya-L1, is poised to capture unprecedented data during the Sun’s peak activity period in 2026. Launched into orbit last year, this mission represents India’s inaugural dedicated solar study endeavor and will witness the star’s dramatic transformation during its 11-year magnetic cycle culmination.

The solar maximum, occurring approximately every 11 years when the Sun’s magnetic poles reverse, generates extraordinary turbulence. This phase transforms our star from relative calm to intense storminess, characterized by a dramatic surge in solar storms and coronal mass ejections (CMEs). These massive eruptions of charged particles from the Sun’s corona can exceed a trillion kilograms in mass and accelerate to velocities approaching 3,000 kilometers per second.

Professor R Ramesh of the Indian Institute of Astrophysics, principal investigator for Aditya-L1’s Visible Emission Line Coronagraph (Velc) instrument, anticipates monitoring capabilities will expand significantly. ‘During normal activity periods, the Sun produces two to three CMEs daily,’ he notes. ‘Next year, we expect ten or more eruptions each day.’

The mission’s advanced coronagraph technology provides a critical advantage over other solar observatories. Its unique design nearly mimics the Moon’s size, completely obscuring the Sun’s photosphere to enable continuous corona observation throughout the year—even during eclipses. This capability allows scientists to study eruptions in visible light while measuring temperature and heat energy, key indicators of a CME’s potential strength toward Earth.

While CMEs create spectacular auroral displays, they pose serious threats to modern infrastructure. Geomagnetic storms can disrupt satellite electronics, disable power grids, and impair communication systems. Historical precedents include the 1859 Carrington Event that disabled global telegraph networks and a 1989 storm that left six million Canadians without power for nine hours.

Recent collaborative research between IIA and NASA analyzed data from a September 2024 CME event—classified as medium-sized despite its staggering characteristics: 270 million tonnes mass, 1.8 million degrees Celsius temperature, and energy equivalent to 2.2 million megatons of TNT. These findings establish a benchmark for evaluating future eruptions during maximum activity.

The insights gained will prove invaluable for developing protective measures for satellites in near-space and enhancing our understanding of space weather dynamics as humanity becomes increasingly dependent on orbital infrastructure.

China’s aerospace program achieved another milestone on Sunday evening as the nation successfully deployed its Shijian 28 satellite into predetermined orbit.

In a landmark achievement for wildlife conservation, Chinese scientists have successfully bred the third filial generation of Chinese sturgeon entirely through artificial propagation techniques. The breakthrough was announced on November 27, 2025, by the China Three Gorges Corporation (CTGC), representing a critical advancement in the preservation of this endangered species.

The historic breeding occurred at CTGC’s Yangtze River Rare Fish Conservation Center, where researchers utilized second-generation captive-bred sturgeon as parent fish. The selected specimens—a 13-year-old female and 14-year-old male—underwent meticulous preparation beginning early this year. This involved specialized nutritional enhancement and carefully controlled environmental simulations to replicate natural breeding conditions.

The actual artificial induction and fertilization procedures were conducted during November 6-7, coinciding with the species’ optimal reproductive window. The scientific team recorded an extraordinary fertilization rate exceeding 95 percent. Following a five-day incubation period, approximately 112,000 third-generation fry emerged, demonstrating the program’s remarkable success.

According to Jiang Wei, Deputy Director of CTGC’s Yangtze River Biodiversity Research Center, this achievement proves that second-generation sturgeon can reach full maturity and reproduce under controlled conditions. This milestone enables a significant transition where the more numerous second-generation population will replace the first generation as the primary breeding group, establishing a sustainable model for large-scale conservation.

The Chinese sturgeon, endemic to China and often described as a ‘living fossil,’ represents one of the world’s most ancient migratory fish species. Conservation efforts began decades ago, with the first generation successfully bred from wild parents in the 1980s, followed by the second generation in 2009. The new breakthrough paves the way for developing comprehensive ‘artificial-plus-natural’ protection systems that could ultimately support the restoration of wild sturgeon populations.

Dubai’s night sky recently hosted an unexpected astronomical spectacle as residents witnessed the annual Leonid meteor shower with unusual urban visibility. Amateur astronomer Abhishek Ashokan made a remarkable discovery during his evening commute on November 17th when he spotted a brilliant celestial streak near the Business Bay toll gate amidst traffic congestion.

Ashokan, whose passion for celestial observation has previously taken him to dark-sky locations like Al Quaa, immediately recognized the phenomenon’s significance. ‘Spotting celestial objects is my hobby,’ Ashokan told Khaleej Times. ‘I immediately had a hunch that I had spotted a meteor.’ Subsequent verification of his dashboard camera footage by the Dubai Astronomy Group confirmed his sighting as part of the Leonid meteor shower that peaked November 18th.

The event sparked widespread public engagement as multiple residents reported similar sightings across social media platforms. Vaisakh Babu, another Dubai resident, accidentally captured the meteor while filming the Dubai Frame in Zabeel Park on November 15th. ‘When I saw weather expert Muhammad Sajjad’s social media post, I realized what I had witnessed,’ Babu explained.

Public reaction revealed fascinating misconceptions about the phenomenon, with many observers initially mistaking the meteors for satellites, laser displays, or even fireworks. One social media user commented: ‘Because I was close to Global Village, I thought it was Skydive Dubai’s yet another stunt.’

The Leonid meteor shower occurs annually when Earth passes through debris from comet Tempel-Tuttle, typically producing 10-15 meteors per hour. The shower’s unusual urban visibility this year marks a significant departure from typical observations that require dark-sky conditions.

Looking ahead, astronomy enthusiasts can anticipate the Geminids meteor shower peaking around December 15th, with predicted rates of 80-120 meteors per hour. Sajjad noted favorable viewing conditions: ‘This year, the moon will only be 23-25 percent visible, making meteors significantly more observable compared to last year’s 80 percent moon visibility.’ Experts recommend traveling beyond city limits for optimal viewing experiences during upcoming celestial events.
