NGC 7392 (also ESO 603-22, MCG -4-53-40 and PGC 69887) is a magnitude +11.9 barred spiral galaxy located 147 million light-years away in the constellation Aquarius. The galaxy was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Obs...
First Globular Cluster Outside the Milky Way The object shown in this beautiful Hubble image, dubbed Messier 54, could be just another globular cluster, but this dense and faint group of stars was in fact the first globular cluster found that is outside our galaxy. Discovered by the famous astronom...

A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos. In one of the longest surveys the telescope will have ever performed, astronomers have begun a three-month expedition trawling for faint galaxies billions of light-years...

Title: Discovery of a W UMa type binary GSC 03553-00845 Author: D.-F. Guo, K. Li, S.-M. Hu, Y.-G. Jiang, D.-Y. Gao, X. Chen When observing the transiting extrasolar planets, we discovered a new W UMa type binary GSC 03553-00845. Following observation was carried out using the 1m telescope at Weihai...
Title: The Current Status of Asteroseismology Authors: C. Aerts, J. Christensen-Dalsgaard, M. Cunha, D.W.Kurtz Stellar evolution, a fundamental bedrock of modern astrophysics, is driven by the physical processes in stellar interiors. While we understand these processes in general terms, w...
Credit: X-ray (NASA/CXC/Harvard/J.Neilsen); Optical & IR (Palomar DSS2) This optical and infrared image from the Digitised Sky Survey shows the crowded field around the micro-quasar GRS 1915+105 (GRS 1915 for short) located near the plane of our Galaxy. The inset shows a close-up of the Cha...
Discovery by astrophysicists to reveal size of neutron star An international team of astrophysicists, led by Sudip Bhattacharyya from the city-based Tata Institute of Fundamental Research (TIFR), have made a discovery using 'thermonuclear burst' to reveal the true size of Neutron stars. [url...
Meteorite smashes into Nicaraguan A mysterious explosion that rocked Nicaragua's crowded capital Managua, creating a large crater, appears to have been caused by a meteorite. Amazingly, in a sprawling city of 1.2 million people, the impact near the international airport did not cause any known...
