In astronomy and observational cosmology, the BOOMERanG experiment (Balloon Observations Of Millimetric Extragalactic Radiation ANd Geophysics) was an experiment which measured the cosmic microwave background radiation of a part of the sky during three sub-orbital (high-altitude) balloon flights. It was the first experiment to make large, high-fidelity images of the CMB temperature anisotropies, and is best known for the discovery in 2000 that the geometry of the universe is close to flat, with similar results from the competing MAXIMA experiment.

  • Experiment BOOMERanG (Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics) se zabýval měřením reliktního záření při suborbitálních letech balónů. Celkem proběhly tři lety, v roce 1997 testovací let nad Severní Amerikou a v letech 1998 a 2003 dva vědecké lety nad Antarktidou. Balon nesl zrcadlo o průměru 1,2 metru, detektory chlazené na 0,28 K, celková vynášená hmotnost byla asi 1 400 kg. Rozlišovací schopnost detektoru byla pouze několik desetin úhlového stupně, což byla mnohem větší přesnost než byla schopna poskytnout COBE. Opoti COBE však bylo možné proměřit anisotropii reliktního záření pouze v malém výseku oblohy. (cs)

  • ( 다른 뜻에 대해서는 부메랑 (동음이의) 문서를 참고하십시오.) BOOMERanG(Balloon Observations Of Millimetric Extragalactic Radiation ANd Geophysics)은 우주 마이크로파 배경을 기구에 의해 관찰한 실험이다. 최초 실험으로는 1997년 북아메리카에서 테스트 비행이 있었다. 이후 1998년과 2003년에 2번의 실험이 있었고 풍선은 남극의 맥머도 기지에서 떠올랐다. 극소용돌이바람에 의해 남극점 주변으로 운반되어 2주 후 되돌아왔다. BOOMERanG 팀은 캘리포니아 공과대학교의 Andrew E. Lange와 로마 라 사피엔차 대학교의 Paolo de Bernardis가 주도하였다. (ko)

  • 毫米波段氣球觀天計畫 (BOOMERanG experiment,Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics),又名回力镖計畫,是三次以高空氣球在次軌道飛行測量部分天區宇宙微波背景輻射的實驗。這是首度以巨大的、高傳真放大影像觀測宇宙微波背景溫度各向異性的實驗,使用一架飛行在42,000公尺高的望遠鏡,讓大氣層在微波的吸收降至極低。雖然僅能掃描天空中極小的一塊區域,但與衛星探測比較,成本降低了非常多。 第一次的飛行實驗於1997年在北美洲完成。後續在1998和2003年的兩次飛行都在南極洲的開始,利用極地渦旋的風在南極盤旋了兩個星期之久,也因此這個望遠鏡有了迴力鏢的名稱。 (zh)
  • BOOMERanG (акронім від англ. Balloon Observations Of Millimetric Extragalactic Radiation ANd Geophysics) — експеримент, під час якого вимірювалось космічне мікрохвильове випромінювання деякої частини неба за допомогою аеростатного телескопа. Це був один з перших експериментів, де було досягнуто на зображенні високу точність анізотропії температури реліктового випромінювання. (uk)

  • L'esperimento BOOMERanG (acronimo inglese di Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics) è un esperimento che ha misurato la radiazione cosmica di fondo di una porzione dello spazio, tramite tre voli sub-orbitali di un pallone di alta quota. È stato il primo esperimento in grado di fornire un'immagine ad alta definizione delle anisotropie della temperatura della radiazione cosmica di fondo. Tramite un telescopio fatto sorvolare ad un'altitudine di 42 km circa è stato possibile ridurre l'assorbimento delle microonde (prodotte dalla radiazione di fondo) da parte dell'atmosfera terrestre.
