New type of matter discovered

Star Stuff - 12 hours 32 min ago
Scientists discover a new type of matter called the tetraquark, which could point to new kinds of stars. Also; first detection of a habitable zone Earth-sized planet, and astronomers find the first possible exo-moon.

Mars in the constellation Virgo – April 18, 2014

Hello my Friends ASOD, I observed a few days ago from the home to the neighboring planet, with good views, but with the pollution of the city there are no problems for red small. Continents showed well defined in my scope and feel free to make this sketch giving rise to the original on the right side shown in the image and colored on the other side giving a hue similar to that shown by the eyepiece, for further reducing the image and display framing the view. It was a nice domestic observation learning a little more about our sister planet perhaps.

Best Regards.

Red stars and big bulges: How black holes shape galaxies

Science Daily - Tue, 04/22/2014 - 08:46
The universe we can see is made up of thousands of millions of galaxies, each containing anywhere from hundreds of thousands to hundreds of billions of stars. Large numbers of galaxies are elliptical in shape, red and mostly made up of old stars. Another (more familiar) type is the spiral, where arms wind out in a blue thin disk from a central red bulge. On average stars in spiral galaxies tend to be much younger than those in ellipticals. Now a group of astronomers has found a (relatively) simple relationship between the color of a galaxy and the size of its bulge: the more massive the bulge, the redder the galaxy.

Solved: Mysteries of a nearby planetary system

Science Daily - Tue, 04/22/2014 - 08:46
Mysteries of one of the most fascinating nearby planetary systems now have been solved. A new study presents the first viable model for the planetary system orbiting one the first stars discovered to have planets - the star named 55 Cancri. Numerous studies since 2002 had failed to determine a plausible model for the masses and orbits of two giant planets located closer to 55 Cancri than Mercury is to our Sun. Astronomers had struggled to understand how these massive planets orbiting so close to their star could avoid a catastrophe such as one planet being flung into the star, or the two planets colliding with each other.

Equipment: Naked eye view

Hello all,

I live in a city with around 9 million of people, just located at 4 degrees north from the ecuador. The light pollution is very intense but I feel also blessed that I can see both hemispheres at the same time from my location. I tried to reproduce the bright of my sky in a clear night in Bogotá and the stars that can be seen in it. I feel I´m improving on Photoshop but there is a long way of trying and learning.

Thanks to all for watching!

Clear Skies.

'Upside-down planet' reveals new method for studying binary star systems

Science Daily - Mon, 04/21/2014 - 21:13
What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems. Astronomers confirmed the first "self-lensing" binary star system -- one in which the mass of the closer star can be measured by how powerfully it magnifies light from its more distant companion star. Though our sun stands alone, about 40 percent of similar stars are in binary (two-star) or multi-star systems, orbiting their companions in a gravitational dance.

God of the Gap: Pan keeps Encke gap open in Saturn's rings

Science Daily - Mon, 04/21/2014 - 10:37
Saturn's moon Pan, named for the Greek god of shepherds, rules over quite a different domain: the Encke gap in Saturn's rings. Pan keeps the Encke gap open through its gravitational influence on the ring particles nearby.

Exoplanets soon to gleam in the eye of NESSI

Science Daily - Mon, 04/21/2014 - 09:05
The New Mexico Exoplanet Spectroscopic Survey Instrument (NESSI) will soon get its first "taste" of exoplanets, helping astronomers decipher their chemical composition. Exoplanets are planets that orbit stars beyond our sun. NESSI got its first peek at the sky on April 3, 2014. It looked at Pollux, a star in the Gemini constellation, and Arcturus, in the Boötes constellation, confirming that all modes of the instrument are working.

Bonjour

Beau spectacle que cette éclipse de Lune du 15 avril, observée en Nouvelle Calédonie. Chapelet réalisé au T400x80 pour bien mettre en évidence les couleurs orangées. Dessin aux crayons de couleur sur papier blanc, puis assemblage informatique.

“Hello

Nice show that this lunar eclipse put on April 15th in New Caledonia. Sketch was done using Chapelet’s T400x80 to include the orange highlights in the obvious places. Drawings completed with colored crayons on white paper, then computer assemblage.”-translation by Frank McCabe
