Topline With the moon reaching its last quarter phase on Saturday, May 9, it begins to rise around midnight, then later each night. The effect is that the night sky as seen from mid-northern latitudes enters one of its final truly dark periods before summer’s short nights take over. It’s a gateway to spring’s deep-sky
Mercury does not look like a world built for extravagance. It is small, battered, sun-scorched and gray. Yet far below that dark surface, the innermost planet may hold one of the stranger planetary treasures in the solar system: a layer of diamond formed under conditions unlike those on Earth. That possibility emerges from a new
The Milky Way is embedded within a flattened ‘sheet’ of matter that extends tens of millions of lightyears, according to new research – a finding that explains a long-standing mystery about how nearby galaxies move. The study, led by scientists at the University of Groningen in the Netherlands, shows that most of the mass surrounding
Parade Pets and Yahoo may earn commission from links in this article. Cane Corsos may not be known for being friendly to strangers — understatement of the year — but this giant breed is the definition of loyal when it comes to familiar faces and family. A social media-savvy Cane Corso named David (how cute
Getting your audio player ready… A new study presented at the European Geosciences Union (EGU) General Assembly in Vienna in April 2026 has put forward a striking argument: that the geometry of Hell as described in Dante Alighieri’s Inferno closely mirrors the physical structure produced by a large planetary impact event. The research, led by
NASA Following the success of its Artemis II crewed mission, NASA is now turning its focus to the next milestones in its plan to put astronauts back on the moon. The space agency has been eyeing a moon landing in 2028, and it’s tapped Blue Origin and
Two ravens soar above a wolf pack in Yellowstone. This type of short-distance following is common, but prolonged following is extremely rare.

Long before the predators finish feeding, the birds gather nearby to grab scraps of

In January 2022, the underwater volcano Hunga Tonga-Hunga Ha’apai in the South Pacific produced one of the most powerful eruptions in modern history. But scientists have now discovered that the eruption also triggered an unexpected atmospheric reaction that partially removed methane, a potent greenhouse gas, from the air. Researchers say the finding could eventually help
A stainless steel breakthrough from the University of Hong Kong (HKU) could help solve one of the biggest problems facing green hydrogen: how to build electrolyzers that are tough enough for seawater, yet cheap enough for large scale clean energy. Led by Professor Mingxin Huang in HKU’s Department of Mechanical Engineering, the team developed a
