ESO Science Announcements

Update on La Silla Paranal Observatory

Published: 12 Jun 2020

All ESO observatories continue to operate in safe mode and no science operation is taking place. All visitor mode runs until middle of July have been cancelled. La Silla Paranal Observatory has developed a ramp-up plan to transition the Paranal, La Silla and APEX Observatories from Safe State to Restricted Operations mode, with the ability to perform basic science operations with limited staffing on site. Once the ramp-up plan is initiated, we estimate a minimum of three weeks until first scientific data can be taken again, and about two more weeks until 'steady state' restricted operations would be reached.

Update on the Status of the ALMA Observatory

Published: 11 Jun 2020

The COVID-19 pandemic continues to impact the global community, including ALMA users and staff. While ALMA operations remain suspended, we have been working actively on plans to restart operations at a time that they become feasible. In these unprecedented circumstances, ALMA’s first priority is the health and safety of all our staff, many of whom travel long distances by bus and plane to reach the remote ALMA telescope site in the Atacama Desert of northern Chile. At this time, and given the current evolution of the COVID-19 outbreak in Chile, it is unclear when a ramp up to start operations could begin, or when a restart of science operations will be possible. ALMA is working on guidelines and considerations for the restart of operations and will provide a next update to the community in the coming weeks.

Workshop Postponed: Inward Bound - Bulges from High Redshifts to the Milky Way

Published: 09 Jun 2020

ESO Headquarters, Garching, Germany 22-26 November, 2021

Due to the difficult circumstances due to the COVID-19 pandemic, the LOC and SOC agreed to postpone this conference to 2021. It will be held as planned at ESO Headquarters. The organisers have studied the possibility of going ahead with an online meeting, but this would have been very detrimental to one of the main goals, which is to foster discussions and collaborations between members of the four different communities (Galactic, extra-galactic, high-z and theory).

Update on Suspended ESO Operations due to the Coronavirus Pandemic

Published: 08 May 2020

All ESO observatories continue to operate in safe mode and no science operations are taking place. As in April and May,  all Visitor Mode runs have also been cancelled for the first two weeks of June. An update will be posted on the La Silla Paranal Observatory news page as soon as ESO starts to ramp up and resume science observations. At present, no date has been set for the commencement of operations.

2020 ESO Studentships

Published: 08 May 2020

The ESO research studentship programme provides an outstanding opportunity for PhD students to experience the exciting scientific environment at one of the world's leading observatories. ESO's studentship positions are open to students enrolled in a university PhD programme in astronomy or related fields. Students accepted into the programme work on their doctoral project under the formal supervision of their home university, but they come to ESO to work and study under the co-supervision of an ESO staff astronomer for a period of between one and two years.
