| 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… |
| Earth’s Busy Neighborhood ~ Minor-object science studies Solar System asteroids, comets, dwarf planets, Kuiper Belt and other trans-Neptunian objects; the Oort Cloud, meteors and meteorites; interplanetary and interstellar dust particles, besides circumstellar disks where such objects exist around other stars. Those on course to collide with the Earth, get a special mention… |
| 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 2017 ~ With about a month to go until the first eclipse seen from the mainland United States in over thirty-eight years, the Internet cranks up a gear. I have previously mentioned the commercial opportunity that represents for some, but this site is maintained by an enthusiast. It is a nightmare to navigate, yet the content augments the input elsewhere from Fred Espenak. |
| 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 have actually expected, to see it from there at all. |
| Eclipse Crossroads of America ~ As the Great American Eclipse fades from the headlines, those in the northeastern and central United States, have less than seven years to wait until the next big event. The village of Makanda in Southern Illinois, saw the lengthiest eclipse in 2017. It is also where the path of the April 8, 2022 eclipse is forecast to intersect with its predecessor. |
| Eclipse Geeks ~ Much has been written about eclipses, especially during recent years. Yet to an objective observer, the response of astrologers to this plethora of scientific data, might seem muted and confused. Countless paragraphs will be written about minor alignments you can’t even see, while such a wholly unforgettable spectacle is often downplayed and misrepresented… |
| Eclipse
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. |
| Eclipse Magnitude & Obscuration ~ The Moon has an elliptical orbit around the Earth, while the Earth’s path around the Sun is equally skewed. Nowadays, folk realise the Moon and Sun look different day to day and thus, between solar eclipses. In short: the magnitude of an eclipse doesn’t necessarily reflect how much of the Sun is obscured. This app does the maths for you… |
| Eclipse Maps ~ What has been dubbed the Great American Eclipse is just a few weeks away. Those in the mainland United States have waited decades, since the path of totality in a full solar event is only seen from a specific area. If you won't be lucky enough to catch the spectacle this time, I’d recommend looking at the maps in this gallery, to find out the next eclipse near you. |
| Eclipse Megamovie ~ This is how the Great American Eclipse looked to those present. From the shores of the Pacific to the coast of the Atlantic, this exceptional event was shared and documented by those surely most deserving of the chance. And fortuitously, the weather didn’t disappoint. Still under development presently; you can savour the spectacle from wherever you are… |
| 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 on forthcoming events: with particular regard to the prevailing weather conditions, a critical factor is you are travelling a very 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 remain forever 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! |
| Encyclopedia
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. |
