... Solar System . Star Clusters . ... Stars@ESO . ... Observations with the Very Large Telescope Interferometer (VLTI) at the ESO Paranal Observatory (Chile) have provided the first-ever direct determination of the angular sizes of the disks of the solar-type stars Alpha Centauri A and Alpha Centauri B. As the two largest members of this triple stellar system that also includes the much smaller Proxima Centauri, they are the Sun's nearest neighbours in space at a distance of just over 4 light-years. ...

... 2003; Sarzi et al. 2006), and the limits on nuclear radio emission are also stringent: <1.5 mJy at 15 GHz (with 150 mas resolution; Nagar et al. 2005) and <0.5 mJy at 5 GHz (with 500 resolution; Wrobel & Heeschen 1991). ... NGC 821 lies 1.5 from the phase calibrator. ... If the 5 GHz detection is real, and the nuclear X-ray emission is smaller by a factor of k2 than the upper limit, then NGC 821 is consistent with the plane, and it may host a radiatively inefficient accretion flow+jet system. ...

Бассейн реки Лены . ... Но уже вскоре, приняв первые притоки, Лена становится сплавной рекой. Началом судоходства на Лене считается пристань Качуга, однако, вплоть до Осетрова по ней проходят лишь небольшие суда, и только ниже его начинается 'настоящая водная дорога' к океану. ... Затем Алдан изгибается широкой дугой и направляется на северо-восток параллельно долине Лены вплоть до поселка Охотский, откуда резко поворачивает на запад, в сторону главной реки, и впадает в нее в 160 км ниже Якутска. ...
