Did our Galaxy grow through violent mergers or through a calmer accretion of gas that fuelled star formation? Studies of other distant galaxies and hunting for clues in our own galactic neighbourhood are teaching us of the hidden history of the Milky Way.
We encounter inner and outer space as we look at connections between the galactic bulge and the halo surrounding the Milky Way.
If the halo can be considered dead, the spiral arms are very much alive, bustling with star formation and blowing bubbles into space.
Over 7-8 February thousands of astronomers packed into the Kensington Conference and Events Centre in London for two days of astronomical talks, telescopes and transactions at AstroFest 2014. Steve Ringwood gives us his highlights from the exhibition, while Max Alexander's photography brings to life memories of the event.
The red planet has returned to our skies and Richard McKim, Mars Section Director for the British Astronomical Association, describes what it has in store for the observer.
In this multi-part series, David Arditti will guide you through the elements of high-resolution imaging and image-processing for the bright planets and the Moon. This month our test object is Mars, at opposition on 8 April.
Keith Cooper investigates how the lost history of the planets, detailing the chaotic events that sculpted the Solar System, is hidden in characteristics of the asteroids.
A wall of debris encircles the Earth, bits of shattered satellites, mislaid equipment, expended rockets and lost nuts and bolts. Jasmin Fox-Skelly looks at ways in which scientists are now seeking to clear up this hazard to navigation.
In our 16-page Night Sky guide: Mars and the two brightest asteroids are at opposition, while Saturn prepares for its best next month and Jupiter lingers in the evening sky.
Canes Venatici, the celestial hunting dogs, is brilliantly placed on April evenings. Within its borders there is so much to see, including five Messier objects, offering huge encouragement to the deep sky enthusiast to explore its wares.
Two telescopes are better than one, as the old saying goes. Olly Penrice describes how imagers can set up telescopes and CCDs in tandem to double their power.
Can cutting edge technology on Celestron's top-of-the-range telescopes get the inexperienced imager off to the best possible start? Damian Peach finds out.
