|Curiosity Rover: Martian Solar Day #2 ~ I’d be remiss not featuring NASA’s Curiosity rover, currently beaming back some of the best pictures of the surface of Mars since landing there on August 6, 2012. This interactive panorama was stitched together and uploaded by Andrew Bodrov from Estonia, member of the International Virtual Reality Photography Association.
Impact Risks ~ Can anyone remember a time when
there wasn’t an asteroid about to hit the Earth? It’s a perennially popular
subject for the media everywhere, but here you’ll find the true facts
and all the latest data. Again a part of NASA’s Near Earth Object program,
making a speciality of this sort of thing!
|Danjon Scale ~ How the Moon appears during a total lunar eclipse is affected by atmospheric conditions here on Earth. While our shadow blocks out any direct light, some is refracted through the atmosphere to give the Moon a copper hue. The Danjon Scale records the luminosity and appearance of a total lunar eclipse. It was first proposed by André-Louis Danjon in 1921…
|Dawn Mission Home Page ~ With the launch of the Dawn mission to the protoplanets (their word!) Ceres and Vesta scheduled for July 7, 2007 this extensive site from NASA answers every question you could possibly have, plus a whole bunch more. Just don’t hold your breath though. Rendezvous with Vesta is scheduled for 2011, with Ceres for 2015…
|Digital Images of the Sky ~ A collection of stunning celestial imagery from those who appreciate and wonder about the beauty of space, rather than aiming to crash rockets into bits of it or send animals to perish out there. The time-lapse movies of intriguing nightscapes and celestial phenomena are fascinating, also the section on the constellations too…
|Dr. Islam’s Astronomy Course ~ At first I thought this would be a dubious parody, but it turns out Dr. Azad Islam really is a professor in the Physics department at SUNY Potsdam, Potsdam, NY from where he seems to draw mixed reviews. Still, his astronomy course is a good introduction to most astronomical basics, while the chapter notes are largely what you ought to review.
|Dwarf Planets ~ You’ll remember, back in August 2006, when Xena became
Eris, Pluto ceased to be a planet and Ceres ceased to be an asteroid, and
all three became the first dwarf planets. That would be that you’d
think, except that at the time of writing, there are six known objects beyond Neptune bigger
than Ceres, and their classification remains unclear…
|Dwarf Planets #2 ~ Now further dwarf planets are being discovered all the time, it’s amusing thinking back to some of the outrageous astrological pronouncements that greeted the discovery of Quaoar, Sedna and Eris for example, when many still thought the chaos of outer space would fit more readily into the existing scheme of things…
|EarthSky ~ An attempt to improve the public perception of science, by offering an accessible platform for scientists to speak directly to their audience, on whatever they are getting enthusiastic over. The popular posts feed of the space section proves interesting, providing details of highlights in the sky at night before other sources…
|Eclipse Chasers ~ Eclipse chasers are people who travel round the world, viewing each total or annular solar eclipse, as these fire off roughly every eighteen months or so. Don’t make the embarrassing mistake of a certain British astrologer, who advised the latest eclipse would be visible from one remote location, when you couldn’t see it from there at all.
Home Page ~ Painstakingly maintained by Fred Espenak of NASA and
the Goddard Space Flight Centre, this site “strives to be the ultimate
resource for online information about eclipses.” From an astronomical
perspective it most certainly is too. Anything you’d ever wish to know
is here, plus a whole bunch more you’d never even thought about.
|Eclipser ~ Jay Anderson is a retired meteorologist who still teaches at the University of Manitoba based in Winnipeg, Canada. These days he devotes his time to chasing solar eclipses around the world and is a knowleable source of reference for those ahead, with particular regard to the prevailing weather conditions, a critical factor is you’re travelling a long way…
|EclipseWise.com ~ Fred Espenak served for over thirty years as NASA’s resident eclipse expert. His knowledge of these phenomena is unsurpassed and extends to his personal website, one of three he currently maintains. Back in 1996, he was the first person I ever emailed. Despite the chasm between astrologers and astronomers, I’ll always be grateful for his personal reply.
|Encyclopedia Astronautica ~ This guy is in love with his subject. Look his name is
Wade, there’s a surprise! Don’t be scared off by the front page and the
eye to erm, design. Anything you wanted to know about space travel is here,
plus a lot more besides, so just start clicking and see where you end up.
Think it isn’t rocket science? Oh yes, it is!
of Astrobiology, Astronomy and Space Flight ~ This site is an online
reference of information about astronomy, astrobiology, space flight,
physics and other areas of science and mathematics, both conventional
and more speculative, such as teleportation and time travel. It is updated
daily by astronomer David Darling.
|Encyclopedia of Meteorites ~ Distinguishing a genuine meteorite or shooting star that fell to Earth, from your average rock and therefore “meteor-wrong” is not a straightforward task. Hence the International Meteorite Collectors Association, whose members will confirm the authenticity of a particular specimen and developed this encyclopedia, to detail and record known finds.
|Ephemeris.com ~ An ephemeris lists planetary positions and other astronomical data, at regular intervals and over a given period. This online ephemeris doesn’t seem to have been updated for a while, but still works beautifully across all operating systems, as well as giving details of your sidereal time that can be hard to find out.
