  Euclid Releases the Foundation of Its First Data Release

  European Space Astronomy Centre, Camino Bajo del Castillo, Sexmo de Casarrubios, El Castillo, Comunidad de Ciudad y Tierra de Segovia, Villanueva de la Cañada, Community of Madrid, 28692, SpainEuropean Space Agency

  

  開始 2026/11/30推定確度 72%68 日後ESA's^[1][2] DR1 timeline page, updated 15 June 2026, gives DR1-Foundation as "November 2026" and the complete DR1 as mid-2027, and says exact release dates will be provided later. A month with no day is estimated at that month's last day, which puts this pin on 30 November 2026; it moves when ESA names the day.

  The first stage of Euclid Data Release 1 puts out all raw data and calibrated images, catalogues and spectra over about 1,900 square degrees of sky. The higher-level products for galaxy clustering and weak lensing follow in mid-2027.

  LIGO Announces the First Detection of Gravitational Waves

  National Press Club, 529, 14th Street Northwest, Downtown, Ward 2, Washington, District of Columbia, 20005, United StatesLIGO

  

  開始 2016/02/11確定確度 88%10.6 年前Wikipedia^[2] dates both the observation and the announcement: "The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO^[3] and Virgo collaborations on 11 February 2016." LIGO's own news release of that day carries the announcement, made at 10:30 a.m. Eastern at the National Press Club, where this pin is placed.

  At a press conference at the National Press Club in Washington, the LIGO and Virgo collaborations announce GW150914, a signal from the merger of two black holes recorded by both LIGO detectors on 14 September 2015 - the first direct observation of gravitational waves.

  LIGO, Virgo and KAGRA Begin the IR1 Observing Run

  NSF LIGO - Hanford, 127124, North Route 10, Richland, Benton County, Washington, 99354, United StatesLIGO

  

  開始 2026/11/15推定確度 68%53 日後The collaborations' own observing plan, last updated 3 September 2026, gives only a window - a six-month run "beginning early- to mid-November of 2026" - and says the next update is due 15 October 2026 or sooner. With no day named, the pin takes the close of the stated window rather than its start, so it is not early; it moves when the collaborations name the day.^[1]

  The gravitational-wave detectors start a six-month intermediate observing run before the fifth observing run. Both LIGO detectors take part, Virgo joins despite possible maintenance interruptions, and KAGRA joins as it becomes available.

  The 1919 Eclipse Results Confirm General Relativity

  Royal Astronomical Society, Piccadilly, St. James's, Westminster, Mayfair, City of Westminster, Greater London, England, W1J 0PA, United KingdomRoyal Astronomical Society

  

  開始 1919/11/06確定確度 85%106.9 年前Wikipedia's^[1][2][3] Eddington experiment article dates the session: "The presentation of the results at the joint 6 November 1919 session of Royal Society and Royal Astronomical Society led to intensive press coverage first in Great Britain and a few days later in the US press". The eclipse itself was on 29 May 1919; this pin is the announcement, which is what made Einstein famous.

  Arthur Eddington presents the results of the May 1919 eclipse expeditions to Principe and Sobral at a joint session of the Royal Society and the Royal Astronomical Society at Burlington House. The measured deflection of starlight matches Einstein's prediction, and the meeting accepts it.
