The Sombrero Galaxy is seen by the Hale

What happens in the center of this spiral galaxy? Call Sombrero Galaxy for its resemblance to the Mexican sombrero, M104 has a very striking dust lane and bright halo consisting of stars and clusters globular. 

The diffuse glow of the extended core of the galaxy is due to the brilliance of billions of old stars. 

Colorful imaged the death of a planetary nebula

The NASA has achieved through his telescope Chandra grasping the end of a star's life, namely NGC 2393, known as "Eskimo Nebula". This study allows astronomers to predict the demise of the Sun, expected within about 5,000 million years.

Planetary nebulae like this are formed when a star consumes all the hydrogen in its core, something will happen to our sun in about 5,000 million years, reports NASA. At the time this happens, 

The first exoplanet that around a solar-type star

That blue dot in the upper right is Gliese 504b (GJ 504b), a giant planet that is 59 light years from Earth orbiting a solar-type star. But what is this special? Have we not already seen several extrasolar planets directly? Yes, but doing a little cheating. And is that exoplanets we have seen directly, as the system HR 8799, for example-are actually training worlds still shine with their own light, especially in infrared. 


Discover the oldest lunar calendar in a field of Aberdeen shire

UK archaeologists have discovered the oldest lunar calendar, found so far, in a field of Aberdeen shire (Scotland). The yearbook is a series of 12 holes that appear to mimic the phases of the moon and the lunar months and is believed chosen about 10,000 years old.

Excavations at the site began a decade ago and the first hole was discovered in 2004. 


Scientists working in Event Horizon Telescope that will see a black hole in detail

An international team of scientists working on the Event Horizon Telescope (EHT) that can combines observations from telescopes around the world (United States, Mexico, Chile, France, Greenland and the South Pole) to see for the first time, to detail, a black hole.

Black holes are invisible to the human eye, 

The NASA Mars rover launch in 2020

A team of scientists and engineers shared some characteristics and the NASA rover sent to Mars in 2020 should look for signs of past life, collect samples for probable arrival to Earth, and test technology for future human exploration of the Red Planet, along with a new statement from the U.S. space agency.

Large sunspot group

In the Academy of Sciences astro photographers circle he was not previously active, even more warmly now our "Welcome". On 7 July this year, he managed the mosaic of an interesting area to a large sunspot group (AR 1785). He used a Meade Refractor (ED 152 mm with 3x Barlow lens) and as a DMK camera 21AU618.AS. At 3657 mm effective focal length (aperture 24) the frames of the video sequence were exposed to 0.2 ms.
