The Liverpool Telescope is a 2.0 metre unmanned fully robotic telescope at the Observatorio del Roque de Los Muchachos on the Canary island of La Palma. It is owned and operated by Liverpool John Moores University, with financial support from STFC.

Planned network outage at ARI Saturday 13th August

Planned electrical maintenance elsewhere at Liverpool Science Park on Saturday 13th August will cause a network outage at Liverpool John Moores University's Astrophysics Research Institute (ARI), where the LT's data archive and website are situated. We apologise for any inconvenience this may cause.

The outage will not affect the running of the LT itself, nor Phase2UI usage. However it will affect user access to the data archive, quicklook, and the rest of the LT website.

It may also affect transfer of the latter part of Friday night's data to the ARI, in which case reduction will not take place on Saturday morning, but the data should be re-reduced early the following week.

The network should be back up late on Saturday 13th or early on Sunday 14th, so the outage should not affect transfer of Saturday night's data, which should be available Sunday as normal.

Latest News from the LT
The atmosphere of Triton in greater detail
20 Apr 2022

An occultation of a star by Neptune's Moon Triton in 2017 has yielded data which advances our understanding of the structure of Triton's atmosphere. Comparisons with earlier events, as far back as a Voyager radio occultation from 1989, implies the atmospheric pressure might have risen in the intervening years but is now back to its 1989 level.

First maintenance on LT in two years
30 Mar 2022

On 10th March telescope director Iain Steele and engineering manager Stuart Bates flew to La Palma for two weeks to address the most pressing maintenance tasks that had built up during two years of travel restrictions to the island. [full story]

Tracking the JWST
21 Jan 2022

A few weeks ago one of the most exciting telescope-related events of 2021 was the launch of the James Webb Space Telescope (JWST). It began its journey with an accurate launch into L2 transfer orbit at 12:20UT on 25th December 2021, and was observed by the LT hours later as it departed Earth. [full story]

Liverpool Telescope Unveils a New Type of Cosmic Explosion, Possibly Linked to Black Hole Formation
12 Jan 2022

LT observations have helped unveil a previously unknown class of cosmic explosion. Research recently published in Nature and soon in the Astrophysical Journal describes the discovery of a new class of supernova — a type "Icn". [full story]

Monitoring Maintenance in Geostationary Orbit
3 Nov 2021

For the first time, remote-controlled spacecraft have begun servicing communications and Earth observation satellites in geostationary orbit to extend the amount of time they can remain in service. [full story]

David Carter
24 May 2021

We are sad to report the death over the weekend of our friend and colleague Professor David Carter. Dave joined LJMU in 1996 as Project Scientist for the Liverpool Telescope and his determined efforts played a large part in keeping the project on track during a difficult construction phase. He was an outstanding scientist who always took a constructively sceptical approach to the prevailing consensus, and an excellent mentor to younger colleagues and students. [full story]

Walk around the LT site
25 Mar 2021

A virtual tour of the Liverpool Telescope site in La Palma is on this website at the Site Tour page. You can walk around the site, even into the telescope enclosure itself, and switch between day and night views. [full story]

Two new nova shells discovered
5 Mar 2021

The expanding debris shells from two separate novae that were seen to erupt decades ago have been discovered and characterised in a recent paper by Éamonn Harvey et al. The paper shows that new nova shells can be found from archive data and new limited multi-epoch followup data from small to medium-sized research telescopes. [full story]
