NICER Status Update

Jan 24, 2025 | nasa.gov | Francis Reddy |Jeanette Kazmierczak

NASA’s NICER Continues Science Operations Post RepairNASA crew aboard the International Space Station installed patches to the agency’s NICER (Neutron star Interior Composition Explorer) mission during a spacewalk on Jan. 16. NICER, an X-ray telescope perched near the station’s starboard solar array, resumed science operations later the same day. The patches cover areas of NICER’s thermal shields where damage was discovered in May 2023.
NASA's Pandora mission one step closer to probing alien atmospheres

Jan 16, 2025 | phys.org | Francis Reddy

Pandora, NASA's newest exoplanet mission, is one step closer to launch with the completion of the spacecraft bus, which provides the structure, power and other systems that will allow the mission to carry out its work. Pandora's exoplanet science working group is led by the University of Arizona, and Pandora will be the first mission to have its operations center at the U of A Space Institute.

Astronomers catch unprecedented features at brink of active black holeby Francis Reddy for GSFC NewsGreenbelt MD (SPX) Jan 15, 2025 International teams of astronomers monitoring a supermassive black hole in the heart of a distant galaxy have detected features never seen before using data from NASA missions and other facilities.
Astronomers catch unprecedented features at brink of active black hole

Jan 13, 2025 | phys.org | Francis Reddy

International teams of astronomers monitoring a supermassive black hole in the heart of a distant galaxy have detected features never seen before using data from NASA missions and other facilities. The features include the launch of a plasma jet moving at nearly one-third the speed of light and unusual, rapid X-ray fluctuations likely arising from near the very edge of the black hole.
XRISM Reveals Stunning Secrets of Mysterious Binary Star Cygnus X-3

Dec 3, 2024 | scitechdaily.com | Francis Reddy

Cygnus X-3 is a high-mass binary consisting of a compact object (likely a black hole) and a hot Wolf-Rayet star. This artist’s concept shows one interpretation of the system. High-resolution X-ray spectroscopy indicates two gas components: a heavy background outflow, or wind, emanating from the massive star and a turbulent structure — perhaps a wake carved into the wind — located close to the orbiting companion.
XRISM mission looks deeply into 'hidden' stellar system

XRISM mission looks deeply into 'hidden' stellar systemby Francis Reddy for GSFC NewsGreenbelt MD (SPX) Nov 26, 2024 The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has captured the most detailed portrait yet of gases flowing within Cygnus X-3, one of the most studied sources in the X-ray sky. Cygnus X-3 is a binary that pairs a rare type of high-mass star with a compact companion - likely a black hole.
