- NASA Summer Internships - Deadline Feb 27, 2026 (4 Feb 2026)
NASA's Office of STEM Engagement (OSTEM) paid internships allow colleg-level students to contribute to the agency's mission to advance science, technology, aeronautics, and space exploration. OSTEM internships offer students an opportunity to gain practical work experience while working side-by-side with mentors who are research scientists, engineers, and individuals from many other professions. Internships may be full-time or part-time, at a NASA center or facility. Join our NASA team and gain valuable on-the-job experience, build your resume, and strengthen your career readiness. We offer three sessions annually, so visit our website often for opportunities. - NASA PostDoctoral Fellowship - Deadline March 1, 2026 (4 Feb 2026)
The NASA Postdoctoral Program offers US and international scientists the opportunity to advance their research while contributing to NASA's scientific goals. The NPP supports fundamental science; explores the undiscovered; promotes intellectual growth; and encourages scientific connections. Selected by a competitive peer-review process, NPP Fellows complete one- to three-year Fellowship appointments that advance NASA's missions in Earth science, planetary science, heliophysics, astrophysics, biological and physical science, aeronautics and engineering, human exploration systems, space operations, space technology, and astrobiology. Search for NPP research opportunities here: NPP Research Opportunities. - NICER AO8 Selected Proposals (26 Jan 2026)
The proposal selection process for Cycle 8 is complete, and a list of selected proposals is now available. - XMMAO (XMM-Newton Accepted Targets) Table (23 Jan 2026)
The latest version of the table of accepted XMM-Newton targets, updated to include AO-24 results, is now available in both Browse and Xamin. - XRISM Cycle 3 proposal submission updates (23 Jan 2026)
The ARK/RPS system is now open for XRISM Cycle 3 proposal submission at JAXA, NASA and ESA, until the deadline on February 27th, 2026. Prospective proposers should check for updates in the Cycle 3 version of the Proposers' Observatory Guide. - Henric Krawczynski wins Bruno Rossi Prize! (21 Jan 2026)
The 2026 Rossi Prize has been awarded to Henric Krawczynski of Washington University in St. Louis, for his contributions to the theory, instrumentation, and scientific interpretation of X-ray polarimetry. Henric has been involved in important discoveries with NASA's Imaging X-ray Polarimetry Explorer (IXPE). He has been an IXPE collaborator since selection of the mission and is first author on IXPE's first paper on stellar-mass black holes. Congratulations Henric!
