Ozone hole

The discovery of the Antarctic ozone hole, as reported in Nature 25 years ago, was one of the most dramatic scientific findings of modern times. To mark the anniversary, Nature presents the original research paper reporting the considerable decline in springtime atmospheric ozone concentration over Antarctica, along with a new Opinion piece from one of the paper's authors, plus a collection of related articles that have advanced our understanding of the stratosphere and the ozone layer, or told the story of the discovery.


Chemist's choice from News and Views

For informed comment on the hottest papers in the chemical sciences, Nature's News and Views section is the place to look. This selection of recent articles provides a taster of what we have to offer, featuring commentaries from the likes of Stuart Schreiber, Chaitan Khosla and Craig Hill.


Year of Astronomy

To mark in 2009 the International Year of Astronomy and 400 years since Galileo made his first telescope observations, Nature has commissioned a series of special articles and reviews. From telescopes to planets, stars, galaxies and cosmology, plus commentary on the state of the field from top experts, we hope they will make you look at the universe with new eyes.


Venus Express

Venus Express is the first mission to Venus in 15 years. It was built by the European Space Agency, launched from Baikonur on a Soyuz-Fregat launcher on 9 November 2005. It arrived at Venus on 11 April 2006 and is in a polar orbit, with a period of ~24 hours. Since arrival its suite of instruments have been collecting data on the atmosphere and magnetosphere. Eight Letters describe the results obtained so far, while a Progress paper by Svedhem et al. gives an overview of the mission.


Future of Computing

In the last two decades advances in computing technology, from processing speed to network capacity and the internet, have revolutionized the way scientists work and many recent scientific advances would not have been possible without a parallel increase in computing power - but with revolutionary technologies such as the quantum computer edging towards reality, how long will the current synergy between computing and science last?


Huygens on Titan

Huygens on Titan

Saturn's moon Titan - larger than the planet Mercury and with an atmosphere - has always intrigued astronomers. Results exceeded expectations when the Huygens probe landed on the surface on 15 January 2005. This special Nature web focus presents the latest findings alongside a comprehensive archive of papers about this fascinating moon. The sights and sounds of Huygens' incredible journey are also featured, including a brilliant descent animation. Image: ESA


Mars Rover

Mars Exploration: It's not rover yet

NASA's twin Mars Exploration Rovers have clocked up more than 1000 days of geological exploration since their launch in January 2004. Nature presents the latest peer-reviewed papers to come from analysis of the rovers' data alongside an archive of news & views, articles, letters and a FREE image gallery.


Mission to Mars

Mission to Mars

Every 26 months, Mars and Earth come into an alignment that minimises the fuel needed to journey between the two. Summer 2003, three new spacecraft took off. Nature introduces these missions with interactive graphics and features on the red planet.


Space shuttle disaster

Space shuttle disaster

Carrying a plethora of experiments, the ill-fated Columbia mission was the first in over three years to be dedicated to scientific research. Nature reports on all aspects of the disaster, including what it means for the future of the space programme.


Cassini

Cassini

During the first few days of 2001, the Cassini spacecraft hurtled past Jupiter. Research and features that paint a dramatic picture of the complex interactions between Jupiter's moons and the giant planet itself.
