There are 10 billion stars in the Milky Way galaxy that are the same size as our sun. Therefore it should come as no surprise that astronomers have identified a clone to our sun lying only 200 light-years away.   Still, it is fascinating to imagine a yellow dwarf that is exactly the same mass, temperature and chemical composition as our nearest star.

This all-sky image shows the distribution of carbon monoxide (CO), a molecule used by astronomers to trace molecular clouds across the sky, as seen by Planck. The inserts provide a zoomed-in view onto three individual regions on the sky where Planck has detected concentrations of molecular gas: Cepheus, Taurus and Pegasus, respectively.

One of the more beautiful Milky Way photos I’ve seen. This one is taken over the two small towns of Gerlach and Empire, Nevada.

Cúmulo NGC 133 (Cr 3; OCl 296). Es un pequeño cúmulo abierto en la constelación de Casiopea. Ubicado cerca de la estrella κ Cassiopeiae; consiste en un puñado de estrellas. Los límites no son fácilmente identificables: se ve como un ligero engrosamiento de asteres diminutos , dispuestos en forma de una Y invertida. Es parte de un grupo de cúmulos abiertos, incluyendo NGC 146 y el disperso Rey 14. Consta de unas veinte estrellas, entre ellas la estrella doble BD + 6293.

Howardite-Bununu-Nigeria-215.1gEons of bombardment pounded the rocks of asteroids into layers of soil called regolith. Later impacts sometimes welded these mixtures of powder and fragments into new rocks called regolith breccias. These rocks contain samples of gas emitted by the Sun solar wind which is trapped only by the uppermost layers of the regolith.Bununu is called regolith breccias.

"It’s like going into your basement and digging a deeper hole," said Petro. "We believe the central part of the Apollo Basin may expose a portion of the Moon’s lower crust. If correct, this may be one of just a few places on the Moon where we have a view into the deep lunar crust, because it’s not covered by volcanic material as many other such deep areas are."

The crater gives us a window into the earliest history of the Moon, and the Moon gives us a window into the violent youth of Earth.

Cluster within a cluster 2

This visible-light wide-field image of the region around the star cluster NGC 6604 was created from photographs taken through blue, red and infrared filters and forming part of the Digitized Sky Survey

This image shows the inner regions of a collapsing, rapidly spinning massive star. The colors indicate entropy, which roughly corresponds to heat: Red regions are very hot, while blue regions are cold. The black arrows indicate the direction of the flow of stellar material. The two white curves with black outlines indicate the neutrino (top) and gravitational-wave (bottom) signals. This frame shows a simulation about 10.5 milliseconds after the stellar core has become a dense proto-neutron…

This image mosaic shows 99 of the nearly 4,000 white dwarfs that Badenes, Maoz, Bickerton, and their colleagues examined. Of the four thousand, they found fifteen double white dwarfs.
