A mixed-up magnetic storm

Astronomy News - 28 August 2014 - 10:08am
The Sun is a variable star, experiencing 11-year-long cycles of activity which impact our planet and near-Earth space. Forecasting the changing space weather and the effects it will have on Earth remains a challenge, as illustrated by an unusual magnetic storm that was observed by ESA’s Cluster quartet and one of the Chinese-ESA Double Star spacecraft.

The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers until now. Astronomers identified a dense galactic core, dubbed "Sparky," using a combination of data from Hubble and Spitzer, other space telescopes, and the W.M. Keck Observatory in Hawaii. Hubble photographed the emerging galaxy as it looked 11 billion years ago, just 3 billion years after the birth of our universe in the big bang.

Astronomers have uncovered for the first time the earliest stages of a massive galaxy forming in the young Universe. The discovery was made possible through combining observations from the NASA/ESA Hubble Space Telescope, NASA's Spitzer Space Telescope, ESA's Herschel Space Observatory, and the W.M. Keck Observatory in Hawaii. The growing galaxy core is blazing with the light of millions of newborn stars that are forming at a ferocious rate. The paper appears in the journal Nature on 27 August.
