As we continue to explore farther out into our solar system and beyond, the question of habitation or colonization inevitably comes up. Manned bases on the Moon or Mars for example, have long been a dream of many. There is a natural desire to explore as far as we can go, and also to extend [...]
In my post below on selection for the “better” zygote Michelle observes that “This would be relatively easy for the father, not so much for the mother.” I took her to mean either of two things, 1) Extraction of eggs is a major surgical affair. Extraction of sperm is not. 2) Males generally have many [...]
With the plethora of mobile apps now available for astronomy applications, it’s hard to keep track of them all. Thanks to astronomer Andy Fraknoi and the American Astronomical Society there’s now a catalog for that. “This catalog is a first attempt to make a list of those of particular interest to astronomy educators,” wrote Fraknoi. [...]
Flooding in Piazza San Marco, Venice Venice is sinking, and the nearby Adriatic sea—like the global sea level—is rising. The city could, some estimates suggest, be underwater by the end of the century. Much of the trouble is due to Venice’s precarious, low-lying position in the middle of a lagoon, but human activity in the [...]
In less than three days, NASA will deliver a double barreled New Year’s package to our Moon when an unprecedented pair of science satellites fire up their critical braking thrusters for insertion into lunar orbit on New Year’s Eve and New Year’s Day. NASA’s dynamic duo of GRAIL probes are “GO” for Lunar Orbit Insertion [...]
Sometimes, over the holidays, it’s easy to think there’s nothing to do. If you feel that way, Sci-ence! wants to have a word with you. [Click to exnihiloenate.] And why, yes, that comic does describe me as a child. … and maybe as an adult, too. Related posts: - In which I disagree with cartoon [...]
There’s a variable in the GSS, GENESELF, which asks: Today, tests are being developed that make it possible to detect serious genetic defects before a baby is born. But so far, it is impossible either to treat or to correct most of them. If (you/your partner) were pregnant, would you want (her) to have a [...]
A few days ago, I posted an incredible picture of Saturn taken from Cassini, showing the partially-lit planet and two of its moons. I used this picture to point out the massive scale of Saturn and its moons, something it’s easy to forget when you’re scanning all the amazing images. BA Bloggee Matt Andrews liked [...]
On 25 January 1995, the British merchant vessel SS Lima was sailing through the Indian Ocean when its crew noticed something odd. In the ship’s log, the captain wrote, “A whitish glow was observed on the horizon and, after 15 minutes of steaming, the ship was completely surrounded by a sea of milky-white color.” The [...]
Scientists studying satellites orbiting the planet have come to an astounding conclusion: Earth has multiple moons at any given time, the MIT Technology Review reported. Mikael Granvik, along with colleagues at the University of Hawaii, first discovered a mysterious body orbiting the Earth in 2006. The object -- or RH120 as it was known -- turned out to be a tiny asteroid just a few meters across. Moreover, it was a natural satellite just like our moon.
Scientists have found two Earth-sized planets orbiting a star outside the solar system, an encouraging sign for prospects of finding life elsewhere. This illustration provided by the Harvard-Smithsonian Center for Astrophysics shows artist’s renderings of planets Kepler-20e and Kepler-20f compared with Venus and the Earth. They’re the smallest planets found so far outside the solar system. Scientists are seeking Earth-sized planets ...
Nasa’s Mars rover Opportunity has found slivers of a bright material that looks very much like it is gypsum (calcium sulphate). If confirmed, it would be the most unambiguous signal of water activity yet found on Mars by this mission, which manages to keep on rolling. "To me, this is the single most powerful piece of evidence for liquid water at Mars ...
Astronomers have confirmed the existence of an Earth-like planet in the "habitable zone" around a star not unlike our own. The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and has a temperature of about 22C. It is the closest confirmed planet yet to one like ours - an "Earth 2.0".
