ER-2 Aircraft Captures Moonlight to Calibrate Space Sensors

An instrument designed to measure the Moon’s brightness completed a three-week mission on a high-flying plane on Feb. 5. Using the Moon as a natural calibration source improves the accuracy of space-based sensors that provide data to observe weather patterns, survey agriculture, and study the Earth’s ecosystems. The

Scoria Cones on Earth and Mars

Mariner 9 images from the 1970s revealed massive shield volcanoes and extensive lava plains on Mars, including Olympus Mons and Alba Mons. Those volcanoes were primarily built by basaltic effusive eruptions—relatively calm outpourings of runny lava that spread across the surface in sheets—and effusive volcanism accounts for the

Crocodile captured in Newcastle creek far south of natural range

A freshwater crocodile was captured in a city creek in Newcastle — about 100km north of Sydney — after teenagers spotted the animal in Ironbark Creek on Saturday. The sighting at Federal Park in Wallsend, close to a local pool and a primary school, drew alarm from visitors. A mother who went

Rare blood moon to be visible across North America, Australia and New Zealand

North America, Australia and New Zealand will be treated to a rare total lunar eclipse on Tuesday known as a 'blood moon'. As the full moon dips into the planet’s shadow it will change colour to a "deep and coppery red", says astrophysicist Dr Rebecca

Norway’s Centuries-Long Watch on the Northern Lights

Perched atop Mount Halde, a small stone building erected in 1899 by Kristian Birkeland became the world’s first permanent northern lights observatory and a base for early 20th-century study of the aurora. Norway has long been seen as the birthplace of auroral research; as the Danish writer Erik Johan

How a Horse Whinnies: With a Whistle and a Song

In a laboratory in France, researchers examined horse larynges, adding tubes and helium to tease apart how a whinny is made. They concluded a whinny combines two mechanisms: a low, sung tone from vibrating vocal folds and a high, whistled tone produced when air is forced through the larynx. The

The Evolution of Eyes Began With One

Scientists now propose that the vertebrate eye traces back about 560 million years to a cyclopean invertebrate with a single patch of light-sensitive cells on the top of its head. That primitive organ likely tracked day and night and helped the animals orient themselves while they poked their heads out
