New analysis method predicts disruptive solar flares

Solar flares—violent explosions on the surface of the sun—can send blasts of radiation hurtling toward Earth. While the planet's magnetic field protects humans on the surface, powerful solar flares can disable satellites, ...

NASA Juno takes first images of jovian moon Ganymede's north pole

On its way inbound for a Dec. 26, 2019, flyby of Jupiter, NASA's Juno spacecraft flew in the proximity of the north pole of the ninth-largest object in the solar system, the moon Ganymede. The infrared imagery collected by ...

Study reveals strange magnetic behaviour 8-11 million years ago

Research by the University of Liverpool has revealed that strange behaviour of the magnetic field in the South Atlantic region existed as far back as eight to 11 million years ago, suggesting that today's South Atlantic Anomaly ...

The magnetic history of ice

The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Scientists at the Weizmann Institute of Science propose a new means of reading this historic record: in ice. ...

Why pulsars shine bright: A half-century-old mystery solved

When Jocelyn Bell first observed the emissions of a pulsar in 1967, the rhythmic pulses of radio waves so confounded astronomers that they considered whether the light could be signals sent by an alien civilization.

Ultra-bright X-ray source awakens near a galaxy not so far away

A new ultra-bright source of X-rays has awakened in between our galactic neighbors the Magellanic Clouds, after a 26-year slumber. This is the second-closest such object known to date, with a brightness greater than a million ...

Swarm probes weakening of Earth's magnetic field

In an area stretching from Africa to South America, Earth's magnetic field is gradually weakening. This strange behaviour has geophysicists puzzled and is causing technical disturbances in satellites orbiting Earth. Scientists ...

Building single-atom qubits under a microscope

Our team at IBM Research made a breakthrough in controlling the quantum behavior of individual atoms, demonstrating a versatile new building block for quantum computation.
