Astronomers using ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) have observed the densest, most crowded regions at the centers of the Large and Small Magellanic Clouds, our Milky Way Galaxy’s closest dwarf companions, offering an unprecedented look at areas that have long resisted detailed study. This image from ESO’s VISTA telescope shows the Large Magellanic Cloud. Image...

Using images from the LROC instrument onboard NASA’s Lunar Reconnaissance Orbiter (LRO), scientists have discovered the biggest newly formed impact crater ever discovered in the Solar System. The crater, now named McGetchin, appeared on the Moon’s eastern edge in 2024. This close-up view of McGetchin crater was taken on December 5, 2025, by the Narrow-Angle Camera (NAC) onboard NASA’s Lunar...

CERN Physicists Find Evidence of One of Higgs Boson’s Rarest Decays

Physicists from the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) have found evidence of the Higgs boson decaying into a ‘virtual’ photon and a real photon, which in turn produces a pair of leptons. This pathway, known as H→γ*γ→llγ, occurs in just one in about 10,000 Higgs decays, making it one of the particle’s most elusive behaviors. Event display of a candidate Higgs...

In a study of 2,266 workers in Finland, evening-type people, or night owls, were up to three times more likely to be treated for depression or anxiety than morning types, with poor work-life balance identified as a key contributing factor. Merikanto et al. showed that evening-types had more issues regarding work spillover to personal life and poor recovery from work and that these factors moderated...

Australia’s North Pole Dome Crater is Earth’s Oldest and Only Known Archean Impact Structure

The North Pole Dome crater: (A) simplified map of the East Pilbara Terrane (EPT, Western Australia), showing Paleoarchean granite domes (pink) and greenstone belts (greens and blues); the North Pole Dome (NPD) lies near the terrane center; (B) geological map of the NPD and the shatter-cone field (yellow star); (C) A quartz (Qtz)-carbonate vein cutting shatter-cone lineation.

Zircon crystals and impact-altered minerals show that a massive asteroid slammed into what is now the Pilbara region of Western Australia about 3 billion years ago.
