ACA-SIM relies on real satellite radiance and in situ reflectance from AERONET-OC sites.

ACA-SIM reduces errors and striping artifacts in derived ocean color products.

XMM-Newton tracked the evolution of the initial flare with its Optical Monitor and assessed the strength of the winds using its European Photon Imaging Camera (EPIC).

This is the first observation where a rapid X-ray explosion from a black hole immediately triggered ultrafast winds, which formed in just one day.

Liyi Gu, the lead researcher at the Space Research Organization Netherlands, stated that they had never observed a black hole creating winds so rapidly before.

XRISM detected the flare and winds using its Resolve instrument, studying the speed and structure of the winds and discovering how they were ejected into space.

By focusing on an active supermassive black hole, the two telescopes discovered rapid, ultrafast winds triggered by flares that resemble those forming on the Sun.

XMM-Newton has been a pioneering explorer of the hot and extreme universe for over 25 years.

On November 11, a coronal mass ejection was detected following an intense solar flare, with winds associated with this event launched at initial speeds of 1,500 km per second.

Understanding the magnetism of AGNs and how they generate such winds is crucial for understanding the history of galaxies throughout the universe.

XRISM aims to address key questions about how matter and energy move in the cosmos since its launch in September 2023.

Matteo Guainazzi, a scientist for the XRISM project at ESA, noted that AGNs are fascinating and key targets for both XMM-Newton and XRISM.

The supermassive black hole is located within the spiral galaxy NGC 3783.

XRISM is a mission led by JAXA with ESA and NASA participation.

The winds emitted by the black hole resemble large solar eruptions of material known as coronal mass ejections.

As the X-ray flare faded, fast winds erupted, traveling at one-fifth the speed of light.

The black hole has a mass equivalent to 30 million Suns.

Astronomers observed a bright X-ray flare erupting from the black hole before it quickly faded.

Winds around this black hole seem to have formed when the intricate magnetic field of the AGN suddenly 'straightened out', similar to eruptions that occur on the Sun.

The XMM-Newton and XRISM space telescopes detected an unprecedented explosion from a supermassive black hole.

Erik Kuulkers, a scientist for the XMM-Newton project at ESA, emphasized that their discovery resulted from fruitful collaboration, which is fundamental to all ESA missions.

Windy AGNs play an important role in how their host galaxies evolve over time and how they form new stars.

As the black hole consumes surrounding material, it powers an extremely bright and active region at the center of the spiral galaxy.

This bright region is known as an Active Galactic Nucleus (AGN) and emits all types of light while projecting powerful jets and winds into space.

This study shows that supermassive black holes sometimes behave similarly to our Sun, making these mysterious objects a bit less alien.

The two space telescopes collaborated to discover this unique event and understand the flare and winds of the black hole.

Liyi Gu and colleagues utilized both XMM-Newton and the XRISM mission to study NGC 3783 and its black hole.

The supermassive black hole generated powerful winds, ejecting material into space at a speed of 60,000 km per second.

Indra Group confirmed that the Spainsat NG-II secure communications satellite suffered a significant anomaly caused by an external impact while en route to its geostationary orbital slot.

Indra noted that Spainsat NG-II will be replaced as soon as possible if necessary.

Spainsat NG-II is the second of two spacecraft in the Spainsat NG program designed to provide secure X-band and Ka-band communications for the Spanish Ministry of Defence, NATO allies, and other government agencies.

The Spanish Ministry of Defence confirmed that the event has had no impact on the Defence Ministry’s satellite communications services or on the normal conduct of Armed Forces operations.

Preliminary technical assessments suggest the Spainsat NG-II spacecraft was struck by a space particle.

The Ministry of Defence indicated it is prepared to commission the construction of a third satellite, Spainsat NG-III, if the damage to Spainsat NG-II proves irreparable.

Hispasat stated that the propulsion or control systems of Spainsat NG-II may have been compromised during the transfer phase.

The incident involving Spainsat NG-II occurred at an altitude of approximately 50,000 kilometers from Earth.

Spainsat NG-II was launched on October 23, 2025, aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station.

Technical teams from Hispasat and the manufacturing consortium are analyzing telemetry data to determine the recovery status of Spainsat NG-II.

The Spainsat NG program, managed by Hisdesat, represents a critical infrastructure investment valued at over €2 billion.

Hispasat, the operator of Spainsat NG-II and a subsidiary of Indra, has activated emergency contingency protocols.

Indra Group recently completed its acquisition of a majority stake in Hispasat.

According to the Spanish Ministry of Defence, secure communications services remain uninterrupted due to Spainsat NG-I and the legacy Spainsat satellite.

The satellites in the Spainsat NG program were manufactured by a consortium led by Airbus Defence and Space and Thales Alenia Space.

The first satellite in the Spainsat NG program, Spainsat NG-I, was launched in January 2025 and is currently fully operational.

The full extent of the damage to Spainsat NG-II remains under analysis.

The transaction aligns with L3Harris' strategic shift to focus on national security and high-priority defense architectures.

L3Harris has divested more than $4 billion worth of non-core assets to streamline its defense-centric operations since the 2018 merger of L3 and Harris.

The transaction is valued at over $500 million for the majority interest and represents a total enterprise value of approximately $845 million for the portfolio.

L3Harris will retain a 40% minority stake in the space and propulsion businesses after the sale.

Proceeds from the sale are expected to be used for debt reduction and expanding production capacity for solid rocket motors and munitions.
