What Venus Express' Visual Monitoring Camera images of Venus have taught us about the motions of Venus' atmosphere.
Beautiful maps of a mysterious place.
I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!
Dispatches from five different worlds--all sent by robotic spacecraft on the same day.
Some lovely, rarely-seen images from the MESSENGER mission.
In which I dive into the Magellan radar data set and come up with some images of an unusual and possibly unique solar system terrain: tessera.
Tuesday morning at the Division of Planetary Sciences meeting featured talks on the surface composition and landforms on Titan, including lakes and
We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.
Talk about changing climates on this world and others brought 600 people to the Boulder Theater.
Unless you are lucky and healthy enough to live for another 105 years, tomorrow will be your last chance to see a Venus transit from the surface of the Earth. But this need not be the last transit of Venus that you will ever see.
The upcoming rare transit of Venus is one step in a long dance among Earth, Venus and the Sun. Transits of Venus follow a peculiar pattern—two transits 8 years apart, then 105.5 years with no transits, then two transits 8 years apart, then 121.5 years with no transits, for a total cycle of 243 years—and thereby hangs a tale.
Each Magellan images of Venus seems to be a work of abstract art.
At the end of last week, a rather sensational article appeared in both the Russian- and English-language sites of the Russian news agency, RIA Novosti.
During the afternoon poster session at the Division of Planetary Sciences / European Planetary Science Congress meeting, I had a long talk with Ludmila Zasova (IKI) about Russia's Venera-D mission to Venus.
I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.
What can you expect to see if you look at the night sky this summer (2011)?
There is a traffic jam of planets on the eastern horizon in the early morning right now and for the next several weeks, a prize for those of you who have to rise before dawn.
Space.com has taken advantage of the infinitely scrollable nature of Web pages to produce a really cool infographic on the scales of orbital distances in the solar system.
Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly
Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.
