NASA Announces Final Text and Deadlines for XRISM Mission Proposals

NASA has released the final text and due dates for proposals related to the X-ray Imaging and Spectroscopy Mission (XRISM) under the ROSES-25 Amendment 28. XRISM, a collaborative mission led by the Japan Aerospace Exploration Agency (JAXA) with contributions from NASA and ESA, aims to study high-energy emissions from various astrophysical sources. The mission will explore stars, X-ray binaries, and galaxy clusters, among others. Proposals for the XRISM General Observer program are due by February 27, 2026. The amendment also introduces opportunities for joint observations with other observatories like XMM-Newton and NuSTAR.

NASA's XRISM Mission Opens New Opportunities for Astrophysical Observations

NASA has released the final text and due dates for the D.3 XRISM General Observer (GO) program, part of the Research Opportunities in Space and Earth Sciences (ROSES) 2025. The XRISM mission, a collaboration between NASA, JAXA, and ESA, aims to study high-energy emissions from various astrophysical sources such as stars, supernova remnants, and galaxies. The program invites proposals for space science observations using XRISM, with deadlines set for February 27, 2026. The mission allows for joint observations with other observatories like XMM-Newton and NuSTAR, enhancing the scope of scientific research.

Astronomers Document Unprecedented Black Hole Winds in NGC 3783

Astronomers Document Unprecedented Black Hole Winds in NGC 3783

Leading X-ray observatories XMM-Newton and XRISM have observed a unique event involving a supermassive black hole in the spiral galaxy NGC 3783. The black hole, with a mass equivalent to 30 million Suns, exhibited a rapid X-ray flare followed by ultra-fast winds traveling at 60,000 km per second. This phenomenon was captured over a few hours, marking the first time such rapid wind formation has been documented. The winds, triggered by the flare, resemble solar coronal mass ejections, suggesting similarities between black hole and solar physics. The event was studied using the European Space Agency's XMM-Newton and the JAXA-led XRISM mission, with participation from ESA and NASA.

U.S. Approves $2.68 Billion Munitions Sale to Canada to Enhance Military Capabilities

U.S. Approves $2.68 Billion Munitions Sale to Canada to Enhance Military Capabilities

The U.S. Defense Security Cooperation Agency has approved a $2.68 billion sale of air-launched munitions to Canada. This sale includes Joint Direct Attack Munitions (JDAMs) and Small Diameter Bombs (SDBs) to support the Royal Canadian Air Force's operations. The munitions will be used for Canada's CF-188 Hornet, CF-35A Lightning II, CQ-9B SkyGuardian, and CP-8A Poseidon fleets. The sale is part of the U.S. Foreign Military Sales program and includes related support, sustainment, and training. This acquisition aligns with Canada's defense policy to increase munitions reserves and enhance military readiness.

Astronomers Observe Unprecedented Black Hole Flare Triggering Ultra-Fast Winds

Astronomers Observe Unprecedented Black Hole Flare Triggering Ultra-Fast Winds

Astronomers using the XMM-Newton and XRISM observatories have documented a rare event involving a supermassive black hole in the galaxy NGC 3783. This black hole, located approximately 130 million light-years from Earth, emitted a sudden X-ray flare that quickly diminished, followed by the emergence of ultra-fast winds. These winds, moving at about one-fifth the speed of light, were observed for the first time forming in just a single day. The event was captured in real-time, providing new insights into the behavior of black holes and their influence on surrounding environments. The black hole, with a mass of about 30 million Suns, is part of an Active Galactic Nucleus (AGN), a highly energetic region that emits light across the electromagnetic spectrum.
