China’s groundbreaking Einstein Probe (EP) astronomical satellite is fundamentally reshaping humanity’s understanding of the dynamic X-ray universe, capturing previously undetectable cosmic phenomena with unprecedented precision. Since its January 2024 launch under the Chinese Academy of Sciences’ leadership, this international collaboration mission has been delivering a steady stream of extraordinary discoveries that are expanding the frontiers of high-energy astrophysics.

The satellite’s advanced instrumentation includes two complementary X-ray telescopes: the Wide-field X-ray Telescope (WXT) utilizing innovative lobster-eye optics to monitor one-tenth of the entire sky simultaneously, and the Follow-up X-ray Telescope (FXT) providing detailed observation capabilities with superior angular resolution. This technological synergy enables the detection of transient cosmic events ranging from seconds to years in duration, capturing faint signals that previously remained hidden in the darkness of space.

Among its landmark discoveries, EP detected EP241021a—a remarkably prolonged X-ray transient persisting for at least 40 days, resembling a slowed-down cosmic firework accompanied by a relativistic jet. Published in The Astrophysical Journal Letters, this finding suggests either a star being torn apart by an intermediate-mass black hole or an unusual core-collapse explosion of a massive star, offering new insights into catastrophic cosmic events and jet formation mechanisms.

In September 2024, the probe captured EP240904a, an exceptionally faint X-ray burst within the Milky Way approximately 100 times dimmer than typical black hole eruptions. This discovery, also published in The Astrophysical Journal Letters, represents a breakthrough in identifying previously hidden black hole populations in our galaxy through its distinctive X-ray ‘heartbeat’ and spectral evolution patterns.

The mission’s autonomous capabilities were demonstrated with EP240801a, an extremely ‘soft’ X-ray flash where low-energy X-rays dominated radiation. The probe independently detected this transient event and immediately triggered follow-up observations, showcasing its sophisticated automated monitoring system that completed the entire process from discovery to tracking without human intervention.

This collaborative effort involving the European Space Agency, Germany’s Max Planck Institute for Extraterrestrial Physics, and France’s CNES space agency has established China as a leading force in time-domain astrophysical research, providing astronomers worldwide with unprecedented tools to explore the most extreme physical phenomena in the cosmos.

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.
