Sunspots are temporary features in the Sun’s photosphere that are caused by intense magnetic field lines emerging from the interior. The spot appear dark because it is relatively cooler then the surrounding photosphere. ... ATMoB Clubhouse, Westford, MA, 12 May 2012. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

This is a copy of a Press Release from E.S.O. Eight years after the passage of Comet Halley in early 1986, astronomers at the European Southern Observatory have succeeded in obtaining an image of this famous object at a distance of no less than 2,820 million km from the Sun. ... The image shows the 6 x 15 km avocado-shaped nucleus as an extremely faint point of light without any surrounding dust cloud. ... This observation was made with the ESO 3.58 metre New Technology Telescope (NTT). ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...

... Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear enable us to see the flaring structure of the disks around Herbig Ae stars. Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. ...

http://hubblesite.org/newscenter/archive/releases/1996/22/text/ Probing the mysterious heart of the Crab Nebula, the tattered remains of a stellar cataclysm witnessed more than 900 years ago, astronomers using NASA's Hubble Space Telescope have found that the Crab is even more dynamic than previously understood, based on a cosmic "movie" assembled from a series of Hubble observations. ... Because of this flickering, the neutron star is also called a "pulsar." ...

The Russian Parliament will soon consider a bill that would restructure the Russian space program, 35 years after the launch оf Sputnik. ...

Serguei NATANZON (UIM, Moscow): Klein topological field theories . It is well-known that classical two-dimensional topological field theories are in one-to-one correspondence with commutative Frobenius algebras. An important extension of classical two-dimensional topological field theories is provided by open-closed two-dimensional topological field theories. In this paper we extend open-closed two-dimensional topological field theories to nonorientable surfaces. ...

... The Einstein On-Line Service (EOLS) is a simple menu-driven system which provides an intuitive method of querying over one hundred database catalogs. In addition, the EOLS contains over 30 CD-ROMs of images from the Einstein X-ray Observatory which are available for downloading. The EOLS provides all of our databases to the NASA Astrophysics Data System (ADS) and our documents which describe each table are written in the ADS format. ... The EOLS provides three options for data retrieval. ...
