    Until now, the most distant spectroscopically confirmed galaxies known in the Universe were at redshifts of z = 8.2 and z = 6.96. It is now reported that the galaxy UDFy-38135539 is at a redshift of z = 8.5549 ± 0.0002. The finding has implications for our understanding of the timing, location and nature of the sources responsible for reionization of the Universe after the Big Bang.

    Infrared spectroscopy can probe the conditions and compositions of exoplanet atmospheres. Previous results relied on space-based telescopes that do not provide spectroscopic capability in the 2.4–5.2 μm spectral region. Here, ground-based observations of the dayside emission spectrum for HD 189733b are reported between 2.0–2.4 μm and 3.1–4.1 μm; an unexpected feature at around 3.25 μm is found that is difficult to explain with models that assume local thermodynamic equilibrium conditions, and is assigned to methane.
