Later, I would read Robert Forward’s work, and realize that an interstellar community was growing in space agencies, universities and the pages of […]

But Sarah Stewart (UC-Davis) and Simon Lock (a graduate student at Harvard University) […]

That?s true whether the people involved are scientists, or stock brokers, or writers. It?s all too easy to distort the surrounding facts because we want to get a particular result, a process […]

  • Best Images Yet of Fomalhaut Debris Disk
    The ongoing dimming of Boyajian?s Star will result in a flood of new data from a wide variety of instruments worldwide, excellent news for those trying to piece together what is happening here. I hope you saw Tabetha Boyajian?s interview with David Kipping over the weekend, but if not, you can see it archived here. […]
