July 2025 offers a fine chance to check Mercury off of your skywatcher’s life list.

Scientists have launched menstrual cups into space for the first time, testing whether these reusable devices can withstand the extreme conditions of space travel. The AstroCup mission represents a key step toward giving female astronauts sustainable menstrual health options during long duration missions to the Moon and Mars.

Scientists have developed a new method to identify and map plastic waste in urban areas using satellite imagery, offering new hope for tracking pollution and improving waste management in cities worldwide. The team of researchers led by Elena Aguilar from the San Diego State University, discovered that common plastic materials have unique "fingerprints" when viewed through special infrared light sensors. Just as different materials reflect sunlight differently to our eyes, plastics reflect infrared light in distinctive patterns that satellites can detect. The WorldView-3 satellite, orbiting high above Earth, captures these invisible signatures with remarkable precision, down to areas as small as 4 meters across. This breakthrough could revolutionise how we monitor urban waste, particularly in areas where traditional ground based surveys are difficult or dangerous to conduct.

We've sent some pretty interesting payloads to space since the first satellite (Sputnik 1) launched on October 4th, 1957. As access to space has increased, thanks largely to the commercial space industry, so too have the types of payloads we are sending. Consider the Nyx capsule created by German aerospace startup The Exploration Company, which launched on June 23rd from the Vandenberg Space Force Base atop a Falcon-9 rocket as part of a rideshare mission (Transporter-14). The payload for this flight (dubbed "Mission Possible") included the ashes and DNA of more than 166 deceased people provided by Celestis, a Texas-based memorial spaceflight company.

If you could see the Universe through a radio-wave "eye", you'd detect mini-halos of relativistic particles creating radio emissions around some galaxy clusters. Astronomers long figured those halos are relative "recent" happenings in the nearby Universe and didn't occur in the early epochs of cosmic history. That's all changed now that the Low Frequency Array (LOFAR) radio observatory in Europe has revealed newborn galaxies in the early Universe already surrounded by a halo of particles. It's a rare look at what such clusters were like soon after they formed.
