Stargazing Live is a British live television programme on astronomy that was first broadcast for three evenings on BBC Two between 3 and 5 January 2011, with a second series broadcast between 16 and 18 January 2012, a third series between 8 and 10 January 2013, and a fourth series between 7 and 9 January 2014. The series is primarily presented by scientist Brian Cox and comedian and amateur astronomer Dara Ó Briain with support from TV presenter Liz Bonnin and astronomer Mark Thompson. It is broadcast from Jodrell Bank Observatory and has featured live links from scientific facilities in Hawaii, South Africa, Norway and NASA.
The first series was scheduled to coincide with the partial Solar eclipse of 4 January 2011, a conjunction of Jupiter and Uranus, and the Quadrantid meteor shower. It also featured Jonathan Ross learning how to spot planets, and a discussion with the International Space Station.
To coincide with each series of the show, hundreds of Stargazing Live events were run across the UK, including star parties and 'sidewalk astronomy' sessions. Many of these events were organised by local astronomy societies and universities.
The show returned for a second series on 16–18 January 2012. The first episode had a theme about the moon, including a live interview with 'the last man on the moon', Apollo 17 astronaut Eugene Cernan. The second episode had a focus on black holes, and the third on the possible existence of extra-terrestrial life. Each episode included different guests, such as impressionist and amateur astronomer, Jon Culshaw on the second night. The final episode also included a feature titled the "Great Big Dulverton Switch Off" where every light in the town of Dulverton, Somerset was switched off live on TV to highlight the issue of light pollution. Each episode of the series was immediately followed by Back to Earth, an additional half-hour discussion of the main show.
During the 2012 series, viewers were encouraged to help locate possible exoplanets, planets orbiting stars outside the Solar System, by volunteering some time on the Planet Hunters online citizen science project. This led to the discovery of a new Neptune-sized exoplanet by two amateur astronomers, one in Peterborough, England, to be named Threapleton Holmes B.
The third series returned with another three episodes. As with the last series, a "Back to Earth" chat was held after each episode. A citizen science project was again featured, this time asking viewers to help in identifying areas of interest in aerial photographs of the surface of Mars. Another feature which ran across the three nights involved the construction of a modern version of William Herschel's 20-foot telescope at the University of Derby.
The fourth series appeared in January 2014, with the citizen science project asking viewers to look for evidence of gravitational lensing in deep space photographs, which resulted in the discovery of dozens of previously unknown galaxies. The series also featured live broadcasts from Norway with the aim of capturing the aurora borealis on camera; although the show's publicity emphasised that the unpredictable nature of the aurora meant this attempt could easily fail, an unexpectedly large coronal mass ejection that week resulted in strong auroral activity, with live footage of the phenomenon being captured on all three nights.
Stargazing Live will be back in 2015 but it will not be held in January which has been the usual month for all previous events, it will be held on 18 to 20 March instead to coincide with next total solar eclipse  which will take place on 20 March 2015.

Series 2 (2012)
Each episode of this series was immediately followed by Stargazing Live: Back to Earth, in which Brian, Dara and their guests discuss the subjects raised in the main show.
|2x01||16 January 2012||The Moon||Brian Cox and Dara O'Briain speak to commander of the Apollo 17 mission Eugene Cernan, Mark Thompson presents a guide to show which telescopes amateurs should use, Liz Bonnin is at SALT in South Africa, and viewers are given the chance to find their own exo-planets.|
|2x02||17 January 2012||Black holes||Brian Cox explains how black holes are formed, Liz Bonnin is at SALT in South Africa, Mark Thompson takes four budding astronomers from the light polluted skies of London to a dark spot, Dara O'Briain explains the live switch off, UFO's are explained and the team from the University run an animation to show the beginning of the Universe.|

Series 3 (2013)
As with Series 2, each episode was followed by Stargazing Live: Back to Earth.
|3x01||8 January 2013||Mars Exploration||Dara O Briain and Professor Brian Cox celebrate our amazing night sky. They kick things off with the search for evidence of life on Mars and ask viewers for help to explore an uncharted area of the red planet's surface.

As with Series 2 and 3, each episode was followed by Stargazing Live: Back to Earth.
|4x01||7 January 2014||Aurora Hunting||Dara O Briain and Professor Brian Cox explain how activity on the Sun distorts the Earth's magnetic field and creates the aurorae. The show coincided with a large coronal mass ejection which resulted in a spectacular display on the third night of the series. Liz Bonnin is in Tromso, Norway showing live pictures of the aurora. Mark Thompson is in Norfolk with the local astronomical societies. Carolyn Porco, head of the Cassini mission imaging team, is a guest at Jodrell Bank and they show Cassini movies of aurorae on Saturn. Viewers are invited to participate in examining 40,000 images of galaxies to identify galaxies which gravitationally lens light from far distant galaxies behind them - the aim was for 500,000 images to be examined in two days; in fact this target was met before the end of that evenings' "Stargazing Live: Back to Earth"!|
|4x02||8 January 2014||Space exploration||Dara and Brian are thrilled to have two of their heroes as guests tonight - Commander Walter Cunningham of Apollo 7, and Commander Chris Hadfield, former commander of the International Space Station. Liz Bonnin takes to the air to view the aurora from 30,000 feet, above the clouds in Norway. Mark Thompson explains how to view satellites in space from Earth. Dara experiences weightlessness on a "vomit comet" aircraft flight.|
