NGC 6582 (also MCG 8-33-29 , UGC 11146 and PGC 61510) is an magnitude +13.9 elliptical galaxy located 663 million light-years away the constellation Hercules. The galaxy forms a close double with the magnitude +14.4 elliptical galaxy PGC 61513 (also known as MCG 8-33-30 , UGC 11146 and PGC 61513) l...
For the past four years, while ESA’s XMM-Newton X-ray observatory has been slewing between different targets ready for the next observation, it has kept its c...
UCLA researchers (Seth Putterman, Brian Naranjo and Jim Gimzewski) appear to have developed a fusion device powered by a pyroelectric crystal, a type of crystal used in cell phones to filter signals. When heated, such a crystal produces a large electric charge on its surface.
They placed a li...
NGC 7492 (also GCl 125) is a magnitude +11.2 globular cluster located 82,500 light-years away in the constellation Aquarius. The distance makes it difficult to resolve into stars, the brightest of them are of visual mag 15.5 so a 250mm telescope is required to observe visually. The globular clus...
Title: The dynamical origin of the Local arm and the Sun's trapped orbit Author: Jacques R. D. Lépine, Tatiana A. Michtchenko, Douglas A. Barros, Ronaldo S. S. Vieira The Local arm of the Milky Way, a short spiral feature near the Sun whose existence is known for decades, was recently observed in deta...
'Warm Neptune' Has Unexpectedly Primitive Atmosphere A study combining observations from NASA's Hubble and Spitzer space telescopes reveals that the distant planet HAT-P-26b has a primitive atmosphere composed almost entirely of hydrogen and helium. Located about 437 light years away, HAT-...
The magnitude 9 asteroid, 14 Irene, is predicted to pass only 0.2° north of magnitude 6 star 92 Virginis (HD 121607). The event this evening is observable from Europe and the Americas. Asteroid 14 Irene was at opposition on the 21st April, 2009. Position(2000): RA = 13h56m27.90s, Dec = +01°03'02.0...
The observatory is a cave modified to allow study of the movement of the sun. The cave was covered with stucco and painted black, yellow and red with a chimney that measured from the base to the surface 8.7 meters, and which is hexagonal in the top. The chimney has a slight slope allowing the sun's rays to...

The 39 - 86 metre wide asteroid 2017 JM2 will make a close pass (5.09 LD, 0.01308 AU), travelling at 14.71 km/second, to the Earth-Moon system on the 15th May 2017 @ 03:49 UT ±00:01. See more The Lunar Distance (LD), the distance between Earth and the Moon, equals 384,401 km, (or 0.00256 AU).
Hubble Catches a Galaxy Duo by the "Hare" This image from the NASA/ESA Hubble Space Telescope shows the unusual galaxy IRAS 06076-2139, found in the constellation Lepus (The Hare). Hubbles Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) instruments observed the galaxy from a dist...
