The locations of recent supernovae near the Sun from modelling ⁶⁰Fe transport
- Volume 11, Issue 15 - article #7
- Fe in deep-ocean crusts indicates that two supernovae exploded in the solar neighbourhood, reheating the superbubble that harbours our Solar System, calculations of the trajectories and masses of the supernova progenitors gives their explosion times and sites, 90â100 parsecs away, with masses around nine times the solar mass, at 2.3 and 1.5 million years ago, respectively.

Galaxies at redshifts 5 to 6 with systematically low dust content and high [C ii] emission
- Volume 10, Issue 26 - article #8
- Measurements of [C ii] emission and dust emission from nine typical star-forming galaxies about one billion years after the Big Bang show that galaxies of this age have dust levels that are significantly lower than those of typical galaxies about two billion years later and comparable with those of local low-metallicity galaxies.

Astronomy: Hubble's legacy
- Volume 10, Issue 15 - article #17
- Twenty-five years after launch, the wild success of the space telescope argues for a new era of bold exploration in the face of tight budgets, says Mario Livio.

In the beginning
- Volume 10, Issue 10 - article #20
- As the first true science journal marks 350 years, we must defend scholarly pursuits.

The formation of a quadruple star system with wide separation
- Volume 10, Issue 6 - article #28
- Observations of a wide-separation quadruple system in the Perseus star-forming region reveal a young protostar and three gravitationally bound dense gas condensations, each condensation is expected to form a star and the closest pair will form a bound binary, while the quadruple stellar system itself is bound but unstable on timescales of 500,000, years.

The exclusion of a significant range of ages in a massive star cluster
- Volume 9, Issue 25 - article #53
- Hubble Space Telescope observations of the stellar cluster NGC 1651, which is approximately two billion years old, show that the colour–brightness distribution of stars old enough to have left the main sequence can be explained only by a single-age population, despite having a feature usually interpreted to indicate an age spread of more than 300 million years.

A massive galaxy in its core formation phase three billion years after the Big Bang
- Volume 9, Issue 22 - article #74
- Hubble Space Telescope, Keck telescope and Spitzer satellite data reveal the formation of the dense stellar core of a massive galaxy occurring three billion years after the Big Bang.

Synthetic biology: Engineering explored
- Volume 9, Issue 19 - article #17
- A simulation that starts 12 million years after the Big Bang and traces 13 billion years of cosmic evolution yields a reasonable population of elliptical and spiral galaxies, reproduces the observed distribution of galaxies in clusters and the characteristics of hydrogen on large scales, and at the same time matches the ‘metal’, and hydrogen content of galaxies on small scales.

Cosmology: Polar star
- Volume 9, Issue 15 - article #6
- After years of work in the Antarctic, John Kovac and his team have captured strong evidence for a long-held theory about the Universeâs birth.

An age difference of two billion years between a metal-rich and a metal-poor globular cluster
- Volume 8, Issue 31 - article #15
- An absolute age of about ten billion years is determined for the globular cluster 47 Tucanae, which is about two billion years younger than the cluster NGC 6397 is thought to be, suggesting that metal-rich clusters like 47 Tucanae formed later than metal-poor clusters like NGC 6397.

A magnified young galaxy from about 500 million years after the Big Bang
- Volume 7, Issue 38 - article #17
- Gravitationally magnified images of a faint galaxy from only 500 million years after the Big Bang suggest that galaxies of that age may be the dominant source of the radiation responsible for the re-ionization of the intergalactic medium.

Postdocs: A voice for the voiceless
- Volume 7, Issue 38 - article #18
- In its first ten years, the US National Postdoctoral Association has helped to raise the profile of postdocs. But championing their cause still presents challenges.

The signature of the first stars in atomic hydrogen at redshift 20
- Volume 7, Issue 27 - article #35
- A simulation of the distribution of the first stars at a cosmic age of about 180 million years reveals that the 21-cm atomic hydrogen signature of these stars is an enhanced (ten millikelvin) fluctuation signal on scales of a few hundred million light-years.

The age of the Milky Way inner halo
- Volume 7, Issue 23 - article #15
- Using observations of four nearby white dwarf stars in the Milky Way halo, the age of local-field halo stars is measured to be nearly around 11 billion years.
