The Complete Sharpless Catalog and Active Storms Worldwide
A comprehensive view of 313 nebulae alongside satellite tracking of storms, flooding, and a wildfire in the United States.
NASA's Astronomy Picture of the Day features a large-scale astronomical mosaic of the complete Sharpless Catalog, comprising 313 ionized hydrogen regions, supernova remnants, and planetary nebulae. According to NASA, astrophotographer Bing Xin captured every object from eastern China and Inner Mongolia in a project requiring approximately 800 total hours of exposure using specialized filters.
NASA's Earth observation satellites are monitoring storm activity across the oceans. According to data from the Joint Typhoon Warning Center and NOAA, Hurricane Rachel was recorded with winds of 105 knots, while Tropical Storm Choi-wan reached 55 knots and Hurricane Nolo was recorded at 50 knots.
On land, NASA's EONET system and GDACS are monitoring significant flood events in Thailand and Mexico. The satellite data tracks water coverage in these regions to aid environmental observation and disaster response management.
In Texas, United States, satellite reporting via NASA and the IRWIN system recorded the San Francisco 2 wildfire in Starr County. According to the data, the fire burned an area of 510 acres.
