With the propagation of data science throughout most industries, the quality of inventive graphics on websites has gone through the roof. This page came across my Facebook feed and is a great example of how awesome interactive graphics can be on a site.…

If you’ve been paying attention this year, you may know that there’s a total Solar eclipse crossing the lower 48 this August. This will be a total solar eclipse, meaning that the Moon will be close enough to the Earth so that it will completely block out…

Okay, so I’ve been trying to wean myself off of IDL in favor of python. Sometimes after you tell yourself you’re not going to develop in a language again you find an awesome new tool …

Spring Cleaning (travel mind edition)

This year my travel has been fairly hectic. While it’s rather on par (or below) for a scientist, this means that it’s above and beyond the pale for a “normal” person.

The Cartwheel Galaxy from Hubble

To some, it looks like the wheel of a cart. In fact, because of its outward oval appearance, the presence of a central galaxy, and their connection with what looks like the spokes of a wheel, the galaxy on the right is known as the Cartwheel Galaxy. To others, however, it looks like a complicated interaction between galaxies awaiting explanation. Along with the two galaxies on the left, the Cartwheel is part of a group of galaxies about 400 million light years away in the constellation Sculptor. The large galaxy's rim spans over 100,000 light years and is composed of star forming regions filled with extremely bright and massive stars. Pictured, the Cartwheel's ring-like shape is the result of gravitational disruption caused by a smaller galaxy passing through a large one, compressing the interstellar gas and dust and causing a star formation wave to move out like a ripple across the surface of a pond.

There’s been some interesting policy commentary on the NASA budget going around today since the budget came out of committee. There’s a bit more going on here than just “Woo! NASA got funded for next year!”.
