An international team based at Cambridge U. has shown how the Sun’s twisting magnetic field lines slip, reconnect, tighten and snarl into a characteristic ’S’ shape. Knowing how such titanic energies build may better predict dangerous larges flares.

Mars and Earth will only be 92 million miles apart at closest encounter in April 2014, called ‘opposition’. Mars will appear red-gold, glowing brighter than first magnitude stars. Only Jupiter, the Moon and Venus before sunrise will be brighter.

An X1-class flare erupted from sunspot AR2017 on Mar. 29th, 2014. NASA's SDO captured the fireworks and NASA's SOHO captured the resulting coronal mass ejection. A magnetic crochet rippled Earth's magnetic field when the flare was in progress.

The central black holes in dwarf galaxies — the "seeds" that grow into the monsters at the core of the Milky Way and other large galaxies — are probably surprisingly weighty, containing 1,000 to 10,000 times the mass of our sun, a new study reports.

When a small NASA-funded rocket launched off planet Earth this month in a dazzling liftoff, it wasn't headed for the final frontier. Instead, the rocket had a closer target: the northern lights dancing over Alaska.

See photos and images of the Mars-bound comet C/2013 A1 Siding Spring, which will buzz the Red Planet on Oct. 19, 2014. Comet Siding Spring was discovered in January 2013. Its pass through the inner solar system will be closely watched by Mars probes.
27 March 2014, 03:09 PM ET
A new Hubble image, captured on March 11, shows what appear to be two jets of dust coming off the nucleus of Comet Siding Spring, which on Oct. 19 will miss Mars by just 84,000 miles — about one-third the distance between Earth and the moon.

On its Asteroid Redirect Mission, NASA hopes to 'encapsulate' an asteroid using a robot ship – and also remove a boulder – before bringing the mass in range of astronauts to perform some, yet unexplained, tasks.

NASA's Asteroid Redirect Mission, to be performed by robots, may attempt to lift a piece of loose rubble from a massive Near Earth Asteroid and return it for analysis. Here is one way this might be done.
