Mar. 31  Another super-luminous supernova
Emmanouil "Manos" Chatzopoulos and J. Craig Wheeler (University of Texas at Austin) have just published, in the Astrophysical Journal, the results of an analysis of supernova 2008am, one of the brightest >>>
Mar. 30  First image of Mercury from orbit
The MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) probe, funded by NASA and managed by the Johns Hopkins University Applied Physics Laboratory, has produced the >>>
Mar. 17  Earthquake: Earth's axis moved by 17 cm
Using a complex mathematical model, Richard Gross of NASA's Jet Propulsion Laboratory (Pasadena, California), has calculated how the magnitude 9.0 earthquake that struck Japan on 11th March has >>>
Mar. 15  The active eye of NGC 4151
43 million light years away, the galaxy we see in this picture has been called the "Eye of Sauron" for the similarity of the image to the evil eye of the "Lord of the Rings" character. It is actually a composite >>>
Mar. 11  Earth: climate information from the core
What relation can there possibly be between the tiny, ten year timescale, variations of Earth's rotational period, the flows of liquid iron in the outer core and climatic variations? Apparently none, and >>>
Mar. 10  More heat than predicted from Enceladus
A study published recently in the Journal of Geophysical Research reveals that the thermal energy produced by Enceladus, a satellite of Saturn, is an order of magnitude greater than predicted by >>>
Mar. 8  Sh2-284, the little elephant nebula
NASA's Wide-field Infrared Survey Explorer (WISE) has produced this curious image of the Galactic star forming region Sh2-284, whose shape, given a little imagination, resembles a baby elephant, with >>>
Mar. 7  More "extraterrestrial" bacteria!
Here we are again. Another sensationalist announcement of the discovery of various species of fossilized "extraterrestrial" bacteria, found within one or more carbonaceous chondrite meteorites. >>>
Mar. 4  Beta Pictoris b, the whole picture
When, 25 years ago, the dusty protoplanetary disk around Beta Pictoris was imaged for the first time, it immediately suggested that planet formation was a common phenomenon. Many years later, in >>>
Mar. 3  Habitable zones at risk from tides
A cold shower awaits those that saw rocky planets located in the so-called "habitable zone" around red dwarfs as one of the most likely places to find life. The habitable zone is the range of distances >>>
Mar. 2  Another asymmetric supernova
By now it is well established that giant stars can explode asymmetrically, even though it seems to occur only in a limited number of cases. The latest example is SN2010jl, that appeared >>>
Mar. 1  Solar pores heat the corona
In this week's Astrophysical Journal, an article appears that may resolve the long standing problem of why the Sun's atmosphere - the corona - passes from about 6000C at the photosphere to over >>>
