Bridging the gap: asteroid collisions without quantum foam
Meteorites originate from violent collisions between asteroids. But can we be sure about that? And what can we learn at all if we do not include ekpyrotic brane cosmologies?
Magnetic Twisters on the Sun
Today’s guest post from Diana Yoder discusses the formation of magnetic twisters in the Sun.
The Multiple Identities of Omega Centauri
Omega Centauri is a huge globular cluster, so much so that some astronomers think it could be the remnant of a disrupted dwarf galaxy. We will see that this is not necessarily true.
Icy Giants: Kepler Exoplanets on Long-Period Orbits
Could icy planets be evading detection, by hiding in the outer reaches of nearby solar systems? Careful re-examination of Kepler data reveals candidate long-period exoplanets.
Shedding Light on the Epoch of Reionization with Ion2
Ion2 is a compact, intensely star-forming galaxy. With its help we can shed light on one of the most significant transitions the Universe underwent – the very transition from being opaque to see-through.
Gazing into the Abyss: Detecting One of the First Galaxies
By searching for Lyman-alpha emission lines, astronomers have confirmed one of the most distant galaxies yet, helping shed light on the very earliest galaxies and their formation.
