Hubble Sights Galaxy in Transition

- Hubble imaged NGC 1266, a lenticular (lens-shaped) galaxy ~100 million light-years away whose face hints at spiral structure but shows no distinct arms, with dust lanes and background galaxies visible. - NGC 1266 is a rare post-starburst galaxy: it hosts a young stellar population but has little ongoing star formation outside its core. - Astronomers infer a minor merger ~500 million years ago funneled gas into the central supermassive black hole, creating an active galactic nucleus (AGN) that produced winds/jets. - Observations show strong gas outflows and shocked, turbulent interstellar material; the AGN-driven removal/disturbance of star-forming gas likely suppressed further star formation, making NGC 1266 a key object for studying galaxy evolution and black hole–host interactions.

NASA Satellites Uncover Large-Scale Ocean Nutrient Stress

- A study published June 5 (Science Advances) combines two decades of NASA MODIS satellite data, ocean surveys, and genetic markers in Prochlorococcus to map phytoplankton nutrient stress globally. - Warming sea-surface temperatures increase stratification, reduce upwelling, and limit surface nutrients, with strongest stress in subtropical gyres and the South

Fighting Fire With Fire

Fighting Fire With Fire

- NASA’s Aqua/MODIS imagery captured smoke from numerous fires in Australia’s Northern Territory on May 28, 2026. - Many detected fires are deliberate prescribed burns, typically lit in mornings to manage savanna fuel loads. - Indigenous practices and modern programs (e.g., WALFA, Arnhem Land Fire Abatement)

NASA-Funded Study Shows Wildfire Smoke’s Hidden Ozone Toll

- A NASA-supported study found that over the past decade wildfires have increased ground-level ozone (smog) across much of the contiguous U.S., worsening air quality far from fires. - Nationally, fires offset nearly four years of ozone-control gains; in the Midwest wildfires erased about 5.3 years of progress
