Millions of Stars in Cigar Galaxy
NASA’s James Webb Space Telescope recently observed edge-on starburst galaxy Messier 82 (M82), nicknamed the Cigar Galaxy. Webb’s new view of M82, added to archival data from NASA’s Hubble Space Telescope, gives us a more complete picture of this starburst galaxy. Because Webb can see infrared light, it is able to peer through clouds of dust and gas to see the shape of this edge-on galaxy, as well as approximately 16.5 million of its stars.
M82’s rapid star formation, thought to be the result of its merger with another galaxy, will only be a (relatively) brief period in its history. Ironically, the extreme star formation is causing plumes of material to be ejected above and below the disk of the galaxy – something that will disrupt future stellar birth.

The Universe's First Stars Were Shaped By Turbulence and Were Not As Massive as Thought
For a long time, astrophysicists thought that the Universe's first stars, called Population III stars, were uniformly massive. It seemed like the conditions they formed in were calm and serene, which favoured massive stars. But new research based on high-resolution simulations show that conditions were more chaotic than thought, and gas cloud turbulence means that Population III stars were not all massive. This affected the metallicity of the next stars to form.

How quantum sensing could reveal hidden faults in thousands of U.S. bridges
Of the more than 624,000 highway bridges in the U.S., an estimated 220,000 need repairs. Quantum sensors could help engineers better safeguard these vital pieces of infrastructure
Europe faces the heat
Europe is facing an intense heatwave, with record temperatures and several cities under red alert. On 23 June, France recorded its hottest June day ever.
This image was captured the same day by the Copernicus Sentinel-3 satellite, which measures land surface temperature from space.
Unlike air temperature, land surface temperature shows how hot the ground itself becomes, often much higher as rock and asphalt absorb heat throughout the day.
Sentinel-3 uses thermal sensors to monitor Earth’s land, oceans, ice, and atmosphere, supporting everything from weather response to long-term climate monitoring.
