Researchers at Eötvös Loránd University (ELTE) have reconstructed approximately 16,000 years of summer temperature changes from sediments collected at Lake Prokoško in Bosnia and Herzegovina. The findings show how the Western Balkans responded to rapid climate changes at the end of the last glacial period, how warmer and cooler phases unfolded during the Holocene, and how the impact of human land use became increasingly pronounced.

Analysis of some nearby stars shows that, despite their name, these bodies can be pink, yellow and more. White dwarfs (artist’s illustration) can be green, a colour that no other form of star has been shown to exhibit. Credit: Mark A Garlick/University of Warwick

Approximately 40 to 70 new comets are discovered every year, most of which are found by astronomers actively looking for comets or at least new celestial bodies in general. But at least one comet discovered in 2026 doesn’t have that distinction. It was discovered entirely by accident by a telescope that was not actively looking for comets. Say hello to C/2026 S1 (Euclid), a brand new comet that was just discovered by the European Space Agency’s Euclid space telescope. The comet is located about 1.3 billion kilometers away from Earth, which is roughly the distance between the sun and the orbits of Jupiter and Saturn. It was discovered by Mikko Pöntinen of the University of Helsinki, together with the Solar System Objects Science Working Group, who were using the Euclid telescope at the time of discovery.

NASA is moving forward with plans to send a suite of instruments to the moon to confirm the existence of a large cave — essentially a tube left behind by lava flows from ancient volcanic activity — that researchers believe is beneath the opening of a pit on the lunar near side. Plans call for launching a rover in 2031 carrying ground penetrating radar, a gravimeter and seismometer, along with optical cameras, to explore a hole known as the Marius Hills pit, which was discovered in 2009 by the Japanese lunar orbiter SELENE (also known as Kaguya in Japan). The pit is believed to provide access to a possible lava tube, based partly on shadows in orbital imagery that suggest an overhanging roof.

Pupils at a school on Anglesey were "very excited" when they met virtually with a NASA astronaut. Students at Ysgol Cemaes were able to put their questions to Frank Rubio on Wednesday, who is set to be part of the crew for the Artemis III mission. Rubio also spent more than a year aboard the International Space Station (ISS) after a fault with the spacecraft that was due to bring him and his fellow astronauts back to Earth. During the virtual session, pupils asked him about his experiences of living and working in space, as well as the challenges and excitement of space travel.

Earlier this year, they took part in a project to design a badge that was sent into space, later seeing it float in zero gravity aboard the ISS. The opportunity was made possible by former pupil Dr Melanie Coathup, a scientist who works closely with astronauts and has helped inspire the school's growing links with the space industry.
