Water in the shadows, from a new source This paper is making the rounds today and describes new observations of the Ceres asteroid/dwarf planet (take your pick) located in the asteroid belt between Mars and Jupiter. The Dawn Mission has been orbiting…

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.

How I make pour over.

A little demo for how I make pour over coffee.

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!”.

Reducing Infinites, a status update

It’s been about 11 months since I started my cleaning experiment to try to reduce the “get to the end of the feed” mentality when consuming content. I figured it was time for an update.

    NASA is currently recruiting a new astronaut corps. I decided to dig into this a little bit (shocking, I know).

Okay, now this is pretty awesome…notice all of the big planets in this poster? There’s a good reason for that.

It’s been a fun year seeing what the scientific community has been doing with NuSTAR. This is from a science group that triggered a Target of Opportunity (ToO), which is basically what happens when something cool goes bump in the night that we either…

New solar observations. NuSTAR's first look at a full-Sun mosaic.

Another way of being part of something awesome. 41 hours to go at this point.
