Graphical Abstract — astro-ph.SR Small polycyclic aromatic hydrocarbons and somewhat larger cyano derivatives were detected in the cold dark cloud TMC-1 recently. Their formation from smaller hydrocarbons is not well
Grid of simulations of atmospheric pressure contribution (bars) and total volume mixing ratio (VMR) for each molecular species as a result of initial volatile abundances. Results are shown for the
KUBIK onboard the ISS — NASA Expanding human space exploration necessitates technologies for sustainable local resource acquisition, to overcome unviable resupply missions. Asteroids, some of which rich in metals like
HELSINKI — China appears set for an in-flight abort test of its new-generation Mengzhou spacecraft next week in a key step for the country’s human spaceflight plans. Images shared on
The discovery by JWST of a substantial population of compact “Little Red Dots” (LRDs) presented astronomers with a major mystery. By reproducing their spectra with simulations, a team argued that
SpaceX launched 26 missions from Kennedy Space Center’s Launch Pad 39-A in 2025, including four human spaceflight missions. That era is coming to an end. A massive crane was put
When Apollo 17 astronauts returned from the moon in 1972, they visited NASA Langley Research Center in Hampton, Virginia, to thank staff for their contributions to the mission, saying “we
NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash toward the upper middle — on Feb. 4, 2026. The image shows a
Few modern systems are as consequential — or as exposed — as the Global Positioning System. A temporary loss of access to its positioning, navigation and timing signals would ripple
