The Old Master Paintings auction on 27 September features a striking mid-16th century portrait of a jester by the Master of 1537, possibly Frans Verbeeck (before 1530–circa 1570).

Now, a new computational study has revealed a surprising structure – a spiral generated by the tidal forces exerted by the Milky Way galaxy itself. The finding, in press at The Astrophysical Journal, ...

Now, a new model suggests that the inner part of the Oort Cloud may have an unexpected structure resembling a spiral, much like a miniature galaxy. The Oort Cloud begins roughly 2,000 – 5,000 ...

TITLE: Could There Be a Common Property Method for Expressions of Both These Constant Numbers Such as Faraday Constant Number and Einstein Constant Number with Nucleotide Bases?

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse.

They found something intriguing hiding in the data. According to their model, the Oort cloud looks like a spiral disk about 15,000 au across, offset by the ecliptic by about 30 degrees.
