Bad Astronomy 27 Jan 2020, 14:00 UTC Whenever I write about supermassive black holes, I am always careful to say that we think they are in the centers of every big galaxy. That's because when we survey the centers of galaxies that are big, like our Milky Way, we tend to see evidence of them.
Centauri Dreams 24 Jan 2020, 17:54 UTC Yesterday’s post on the Spitzer Space Telescope leads naturally to the targets it produced for its successor. For when Spitzer’s mission ends on January 30, we have the far more powerful James Webb Space Telescope, also operating at infrared wavelengths, in queue for a 2021 launch. In many ways, Spitzer has been the necessary precursor for JWST, for it was the need to operate a telescope at extremely low temperatures in order to maximize infrared sensitivity that drove Spitzer design. JWST must maintain its gold-coated beryllium mirror at similarly precise temperatures.
Bad Astronomy 24 Jan 2020, 14:00 UTC Every now and again I'll see a nebula I've never seen before, and it's always a bit of a surprise. I've been doing this scicomm thing a long time, and astronomy in general even longer. I've seen a lot of stuff.
Centauri Dreams 23 Jan 2020, 18:04 UTC The Spitzer Space Telescope, which is to end its mission on January 30, has a special place in my memory. I was making a trip to the Jet Propulsion Laboratory as part of the research for my Centauri Dreams book when I noticed on a monitor a countdown — still in days — for the launch of Spitzer, then known as the Space Infrared Telescope Facility (SIRTF).
Forbes articles by Brian Koberlein 22 Jan 2020, 18:10 UTC With over 4,000 confirmed exoplanets, we're starting to get an idea of which types are common and which are rare. We've learned that our solar system is rather unusual in ways you wouldn't expect. Take, for example, the presence of large planets orbiting small stars.
NASA Space Station Blog 21 Jan 2020, 19:29 UTC The Expedition 61 astronauts have one more spacewalk planned this weekend and they will finish the repair of a cosmic ray detector. This will be the ninth spacewalk for the crew, more than in any other increment in the history of the International Space Station.
