This date in science: Near discovery of South Magnetic Pole

Like all Antarctic journeys in the early 1900s, the search for magnetic south was grueling. The outcome was unclear, but the effort is still remembered.

How to see Comet Catalina

Hints on how to perceive the comet’s gradual motion across the sky as it sweeps closest – but not too close – around January 17.

The Chandra X-ray Observatory caught two waves of hot, X-ray emitting gas emanating from the supermassive black hole at the center of NGC 5195.

What to expect from El Niño

The third-recorded super El Niño is underway. Top climate expert Kevin Trenberth reports.

Runaway star Zeta Ophiuchi plowing through space dust. The bright yellow curved feature directly above Zeta Ophiuchi is a magnificent example of a bow shock. In this image, the runaway star is flying from the lower right towards the upper left. As it does so, its very powerful stellar wind is pushing the gas and dust out of its way (the stellar wind extends far beyond the visible portion of the star, creating an invisible 'bubble' all around it). And directly in front of the star's path the wind is compressing the gas together so much that it is glowing extremely brightly (in the infrared), creating a bow shock. It is akin to the effect you might see when a boat pushes a wave in front it as it moves through the water. Image credit: NASA

Four new elements added to periodic table

The new elements – elements 113, 115, 117 and 118 – complete the periodic table’s seventh row and make science textbooks around the world instantly out-of-date.

Supermoons of 2016

Are supermoons hype? In our opinion … no, just modern folklore. And they cause real physical effects, such as larger-than-usual tides.
