It's also the method by which signals from radio telescopes thousands of miles apart have been correlated after the fact at a central location. This has been the case for a couple of decades now. For instance, at the VLBA: https:&#x2F

Astronomical cameras don't capture color information in the sense that our eyes or consumer digital cameras do. They are "black and white" only detectors. To get color information, several images are taken with different filt

A great service! As a grad student I experienced how much time can be sunk into applying for grants. It can be a real deterrent to looking for new sources of funding and partners. I love that I can enter information once, and have it format

Dust above the surface of the moon is a concern, but another point to consider is that it takes extra fuel to lower down into the gravity well of the moon. Fuel is mass and mass is money. It would be less expensive in terms of fuel to not g

Just last night the SOFIA Observatory observed Pluto during an occultation [1], a very rare event. The main purpose is to help characterize Pluto's atmosphere and, along with New Horizons, the data will help calibrate future Earth-bas

Mark Bittman wrote a nice column about outfitting a "no-frills kitchen" over at the NYT. I came across it via a review of knives over at the wirecutter. I can recommend both. NYT article: < http://www.nytimes.com/2007/05/09/dining/0

It is important to keep in mind that black holes do not "pull" things towards them, they have the same kind of gravity that any other object has, and are also affected by gravity in the same way as other objects. A "miniature" black hole w
