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

Reconnection on the Sun
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).
Discovery of Methanol in a Planetary Birthplace
A milestone ALMA discovery represents a first step in understanding the conditions for planet formation that can lead to life-supporting planets like Earth.
Featured Image: A Bubble Triggering Star Formation
The expanding bubble captured in this infrared image is triggering star-formation as it passes.
A New Way to Confirm Planet Candidates
What’s the punchline from yesterday’s Kepler press conference? Over a thousand new confirmed planets — and a new way to confirm them!
Giant Impacts on Earth-Like Worlds
A recent study examines whether our planet’s history of giant impacts is typical for Earth-like worlds.
Predicting Major Solar Eruptions
Can we predict which solar flares will be followed by larger-scale coronal mass ejections?
An Active Black Hole in a Compact Dwarf
There’s a new addition to the galaxy zoo: a small, compact, and old elliptical galaxy that shows signs of a monster black hole actively accreting material in its center.
Record-Breaking Eclipsing Binary
The new record holder for longest-period eclipsing binary is TYC-2505-672-1, an unusual system in which the companion star may be shrouded by a circumstellar disk.
Featured Image: Modeling Supernova Remnants
A new study examines how a one-dimensional model can be used to reproduce the multidimensional effects of mixing in supernova remnants.
Computers vs. Humans in Galaxy Classification
Can a computer algorithm classify galaxies into ellipticals and spirals as well as Galaxy Zoo’s human volunteers?
Can CMB Experiments Find Planet Nine?
Recent studies have identified signs of an unseen, distant ninth planet in our solar system. A team of scientists have proposed a new way to search for Planet Nine: look for its heat signature.
