NASA’s NICER Maps Debris From Recurring Cosmic Crashes

5 min read NASA’s NICER Maps Debris From Recurring Cosmic Crashes Lee esta nota de prensa en español aquí. For the first time, astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA’s NICER (Neutron star Interior Composition Explorer) and other missions. Scientists have only recently encountered this class of X-ray flares, called QPEs, or quasi-periodic eruptions. A system astronomers have nicknamed Ansky is the eighth QPE source discovered, and it produces the most energetic outbursts seen to date. Ansky also…

NASA Kicks Off Biological Research Aboard Space Station

Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms. Microalgae in microgravity Sophie’s BioNutrients This ice cream is one of several products made with a protein powder created from Chlorella microalgae by researchers for the SOPHONSTER investigation, which looks at whether the stress of microgravity affects the algae’s protein…

Navigation Technology

4 Min Read Navigation Technology ESA astronaut Matthias Maurer sets up an Astrobee for the ReSWARM experiment. Credits: NASA Science in Space April 2025 Humans have always been explorers, venturing by land and sea into unknown and uncharted places on Earth and, more recently, in space. Early adventurers often navigated by the Sun and stars, creating maps that made it easier for others to follow. Today, travelers on Earth have sophisticated technology to guide them. Navigation in space, including for missions to explore the Moon and Mars, remains more of…

NICER Status Updates

April 17, 2025 Following Repair, NASA’s NICER Improves Daytime Measurements A NASA X-ray telescope on the International Space Station called NICER, or Neutron star Interior Composition Explorer, has regained additional daytime observation capabilities thanks to repairs completed during a spacewalk and a reconfiguration of its detectors. In May 2023, NICER developed a light leak in which unwanted sunlight began entering the instrument. Photos taken from inside the space station revealed several small areas of damage to the telescope’s thin thermal shields, which block sunlight while allowing X-rays through to the…
