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.

dbo:abstract
  • 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)
  • تجربة بوميرانج في الفيزياء (بالإنجليزية: BOOMERanG experiment) اختصار لاسم التجربة الكامل Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics) وهي تجربة قامت بقياس إشعاع الخلفية الميكروني الكوني لجزء من السماء من خلال ثلاثة بعثات للبالونات على ارتفاعات كبيرة. وكانت هذه هي أول مرة للقيام بأخذ صور كبيرة واضحة لحرارة الأشعة الخلفية الميكرونية وتغيرها. وباستخدام تلسكوب طار على ارتفاع 42 كيلومتر من سطح الأرض فكان من الممكن خفض امتصاص الجو للموجات الميكرونية (طول موجتها عدة ميكرومترات) إلى أقل حد. وكانت تكلفة تلك التجربة أقل بكثير من تكلفة تلك القياسات التي تتم بواسطة الأقمار الصناعية، إلا أن القياسات كانت منحصرة في جزء من السماء.

  • Das BOOMERanG-Experiment (kurz für "Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics" – Ballonbeobachtungen von extragalaktischer Millimeterstrahlung und für die Geophysik) maß während dreier Ballonflüge die Eigenschaften der kosmischen Hintergrundstrahlung. Dabei gelang es zum ersten Mal, zuverlässige und detaillierte Bilder der winzigen Temperaturfluktuationen dieser Strahlung festzuhalten. Grund für den Einsatz eines Ballons war der Umstand, dass die zu messende Mikrowellenstrahlung durch die Erdatmosphäre größtenteils absorbiert wird. Die ballongestützten Beobachtungen fanden rund 42 Kilometer über dem Erdboden statt, auf einer Höhe, wo die Mikrowellenstrahlen noch gut nachzuweisen sind. Die Nutzung eines Ballons war dabei deutlich billiger als eine satellitengestützte Mission; allerdings ergab sich der Nachteil, dass so nur ein kleiner Himmelsausschnitt beobachtet werden konnte. Der erste Testflug fand im Jahre 1997 über Nordamerika statt. Die zwei folgenden Flüge in den Jahren 1998 und 2003 begannen jeweils an der McMurdo-Station in der Antarktis. Dort sorgt der Polarwirbel dafür, dass der Ballon nach rund zwei Wochen wieder an seinen Startort zurückkehrt – wie die australischen Bumerangs, von denen sich der Name des Experiments ableitet. Leitender Wissenschaftler von italienischer Seite war Paolo de Bernardis, von amerikanischer Andrew E. Lange. (de)

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. By using a telescope which flew at over 42,000 meters high, it was possible to reduce the atmospheric absorption of microwaves to a minimum. This allowed massive cost reduction compared to a satellite probe, though only a tiny part of the sky could be scanned. The first was a test flight over North America in 1997. In the two subsequent flights in 1998 and 2003 the balloon was launched from McMurdo Station in the Antarctic. It was carried by the Polar vortex winds in a circle around the South Pole, returning after two weeks. From this phenomenon the telescope took its name. The BOOMERanG team was led by Andrew E. Lange of Caltech and Paolo de Bernardis of the University of Rome La Sapienza. (en)

  • 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. Il primo volo di prova è avvenuto nei cieli dell'America settentrionale nel 1997. I due voli successivi del pallone sonda sono partiti del 1998 e nel 2003 dalla base permanente antartica McMurdo. Il pallone è stato fatto girare attorno al polo sud sfruttando il vortice polare, con ritorno al punto di partenza dopo due settimane. Il telescopio prende il nome da questo effetto (effetto boomerang). (it)
