Sun and Heliosphere corridor

Meet your new AAS Lead Editor for the Sun and the Heliosphere corridor! Here’s what he thinks about his field, the upcoming SPD meeting, and the publishing process.

Pluto and the solar wind

Recent results from the New Horizons Pluto flyby reveal interesting information about Pluto’s atmosphere and how the solar wind interacts with it.

ISON trajectory

On 28 November 2013, comet ISON passed within two solar radii of the Sun’s surface. But instead of shining in extreme ultraviolet light as predicted, ISON was never detected.


Recent simulations have allowed scientists to examine the brutal process of building a galactic halo out of destroyed satellite galaxies.

Coronal loops

Recent observations have revealed how solar magnetic fields rearrange themselves, producing the tremendous releases of energy we observe as solar flares and coronal mass ejections (CMEs).

protoplanetary disk

A milestone ALMA discovery represents a first step in understanding the conditions for planet formation that can lead to life-supporting planets like Earth.

Star forming bubble

The expanding bubble captured in this infrared image is triggering star-formation as it passes.

Kepler planets

What’s the punchline from yesterday’s Kepler press conference? Over a thousand new confirmed planets — and a new way to confirm them!
