TL;DR: The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its First Data Release as discussed by the authors, which consists of 2099 deg2 of five-band (u, g, r, i, z) imaging data, 186,240 spectra of galaxies, quasars, stars and calibrating blank sky patches selected over 1360 deg 2 of this area.

TL;DR: Using the Gemini Planet Imager, a Jupiter-like planet is discovered orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units and has a methane signature and is probably the smallest exoplanet that has been directly imaged.

Can Giant Planets Form by Direct Gravitational Instability
TL;DR: In this article, it was shown that to form planets directly, it is not enough for protoplanetary disks to be gravitationally unstable, but they must also be able to cool efficiently (on a timescale comparable to the local disk orbital period) to allow the formation of the bound clumps by fragmentation.
