Телескоп Hubble обнаружил у Плутона еще два спутника . ... Снимки, сделанные при помощи орбитального телескопа Hubble, свидетельствуют, что планета Плутон имеет три спутника, а не один, как предполагалось ранее. Девятая планета от Солнца, Плутон, была открыта в 1930 году, а вплоть до 1978 года, когда был обнаружен его спутник Харон, считалось, что небесное тело вращается вокруг Солнца в одиночестве. ...

. Comment on J0318+4151 . No detection: according to global VLBI observations at 5 GHz by Xu, O'Dea & Biretta (1999), the core of this double-tail radio galaxy has a brightness of 13 mJy/beam, too weak for us to be detected. VLBApls home page . Last modified: 16 Oct 2000

... Maps of six sources (0420+022, 0420-014, 1308+326, 1345+125, 1803+784, and DA 193) obtained with milliarcsecond resolution are presented and discussed, together with their broadband (1­22 GHz) spectra obtained on the RATAN­600 radio telescope at epochs close to those of the VLBI observations. ... The image (Fig. 5) shows that the source structure at 18 cm is compact, consisting of a VLBI core and two jet components, with the outer component lying 5 mas (30 pc) to the northwest of the core ( = 54 ). ...

The Archeops experiment aimed at measuring the cosmic background emitted just after the Big Bang. The study of this radiation is essential to obtain precise information on the evolution of the Universe: density, Hubble constant, age of the Universe.. To achieve this goal, measurements have been done with devices cooled down at 100mK temperature placed at the focus of a warm telescope. ... 28960 visitors . ...
