Planetary conjunction between Jupiter Venus and Mercury seen this week

I’d also like to know the answers to both of these questions. I’ll be doing some googling, and I’ll edit this comment if I find anything. EDIT 1: I apologize for using a mobile site, but I’m on my phone, [this](http://mobile.slate.com/blogs/bad_astronomy/2013/05/27/triple_conjunction_jupiter_venus_and_mercury_in_the_west.html) site sent me

An image of Mercury with gravitational anomalies shown in false-color, superposed on an image of the planet’s cratered surface. Red hues indicate areas of slightly higher gravity, which in turn indicates areas that must have unusually dense matter under the surface.

I read [here](https://solarsystem.nasa.gov/news/display.cfm?News_ID=23355) that they have done calculations of Mercury’s gravitational field using the messenger spacecraft. The image is also found in the [wiki page](http://en.wikipedia.org/wiki/MESSENGER#Launch_and_trajectory) along with more details. Once the messenger probe was in orbit around Mercury, they used ground based telescopes (using

I remember the feeling I had first time I have seen these pictures. I have never been more fascinated about a picture ever. Venus always seemed more mysterious to me, since it looks impenetrable. And these soviet missions are not know as much as

Brahin Pallasite (Sliced Meteorite)

[All of the post-iron elements are formed in supernova explosions themselves. So much energy is released during a supernova explosion that the freed energy and copious free neutrons streaming from the collapsing core drive massive fusion reactions, long past the formation of iron. Sure,

this just amazes me

Spoken like a true atheist. You have all the qualifications of one, only difference between you and me is that when I don’t know something, reach a place where I can’t figure something out or can’t understand it I don’t say ‘god did it’.
