... From the Northern to the Southern Cross . ... Credit Copyright: Nicholas Buer Explanation: There is a road that connects the Northern to the Southern Cross but you have to be at the right place and time to see it. The road, as pictured above, is actually the central band of our Milky Way Galaxy; the right place, in this case, is dark Laguna Cejar in Salar de Atacama of Northern Chile ; and the right time was in early October, just after sunset. ...

... This year's most powerful solar flare was photographed by TESIS telescopes in the southern hemisphere of the Sun on July 5th, 2009. ... Events of such power are unique and are only observed during maximal solar activity. ... For two months, all the activity of the new solar cycle was connected with areas of this belt, including the first solar flares and coronal mass ejections of the year. ... Nevertheless, this year's largest solar flare occurred in the southern belt. ...

... Over the course of a week two secondary students James Hadnett and Liam Fields observed NEAs using one of two 2-Metre telescopes courtesy of the Faulkes Telescope Project which are positioned in the Northern and Southern Hemisphere. This was made possible with the aid of Las Cumbres Observatory who, with their Global Telescope Network, give educational establishments the chance to observe with a high grade telescope. ...

Brad Carter, Carolyn Brown, Rhodes Hart Drew Foster, John Kielkopf, Ron Moore University of Southern Queensland, Australia University of Louisville, Kentucky, USA OVERVIEW Mt Kent Observatory is now providing live remote observations of southern skies as part of a collaborative project between USQ, the University of Louisville, and Northern Kentucky University. ... This enables observers to make daytime use of a remote telescope during its local night-time, and image otherwise inaccessible skies. ...

... A similar level of effort is anticipated for HDF-S. We are maintaining a `clearinghouse' for supporting and follow-up observations of the HDF-S. Test observations of the HDF-S field were obtained in October, 1997. ... Simultaneous, parallel observations were made with the three HST instruments STIS, WFPC2 and NICMOS of separate, neighboring fields. ... Additional flanking field observations were made surrounding the deep STIS, WFPC2 and NICMOS fields. ... The red field is the main HDF-S WFPC2 field....

Comet PANSTARRS reaches perihelion, its closest approach to the Sun on 10 March, after this it will start to move away from the Sun and to be visible in the twilight sky to observers in the northern hemisphere. ... It was a very faint and delicate white ?feather? against a deep golden sky.€а It took quite some effort to find even with binoculars and I could not see it at all without them. ...

... The SMS program is a critical endeavor to investigate whether the predictions of standard cold dark matter cosmology are consistent with the observed matter distribution in the Milky Way halo. It is the deepest, most extended search for optically elusive dwarf satellite galaxies and tidal streams to date, covering the entire Southern hemisphere. ... However only a few dwarf satellites have been found around the Milky Way to date - 22 dwarfs compared to 500-10,000 predicted by theory (Klypin et al. ...
