3-in-1 Launch

A SpaceX Falcon 9 rocket carrying NASA’s IMAP (Interstellar Mapping and Acceleration Probe), the agency’s Carruthers Geocorona Observatory, and National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On–Lagrange 1 (SWFO-L1) spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 7:30 a.m. EDT Wednesday, Sept. 24, 2025. The missions will each focus on different effects of the solar wind — the continuous stream of particles emitted by the Sun — and space weather — the changing conditions in space driven by the Sun — from their origins at the Sun to their farthest reaches billions of miles away at the edge of our solar system.

An Eye-catching Star Cluster

Westerlund 1 is the biggest and closest “super” star cluster to Earth. Data from Chandra and other telescopes are helping astronomers delve deeper into this galactic factory where stars are vigorously being produced. Observations from Chandra have uncovered thousands of individual stars pumping out X-ray emission into the cluster.

A Brief Outburst

The Sun blew out a coronal mass ejection along with part of a solar filament over a three-hour period on Feb. 24, 2015. While some of the strands fell back into the Sun, a substantial part raced into space in a bright cloud of particles (as observed by the NASA-ESA Solar and Heliospheric Observatory spacecraft). Because this occurred way over near the edge of the Sun, it was unlikely to have any effect on Earth.

Coral (Favia favus), Ras Muhammad National Park, Red Sea, Egypt. This species of stony corals is massive and forms thickly encrusting dome-shaped colonial corals. There is a great diversity of form even among the same species. The corallites project slightly above the surface of the coral and each has its own wall. The septa and costae linked to the corallite wall are well developed and covered by fine teeth. The polyps only extend and feed during the night. Each one has a small number of tapering tentacles which often have a darker coloured tip; these are called stinger tentacles, or sweeper tentacles. They use these to sweep the water to see if any other coral is in its area; if so, then they begin to sting the other coral. This is commonly known as coral war. Each coral is trying to make sure it has enough room around it so it can continue to grow and have more surface area for its offspring.

A caterpillar of the spurge hawk moth (Hyles euphorbiae), photographed in the Scrivia riverbed, in Novi Ligure, Piedmont, Italy. The larvae of this Europiean hawk moth eat the leaves and bracts of the leafy spurge (Euphorbia virgata), which gives the species its common name.

TDK tape head cleaner cassette “HCL-11” made of clear hard plastic. The plastic is birefringent and demonstrates internal stress as coloured patterns (photoelasticity) when photographed using cross-polarisation. Invented by Lou Ottens and his team at the Dutch company Philips, the Compact Cassette was released on this date in August 1963.
