This ISS Experiment Looks Like A Miniature Star Factory. This Sun-like star is surrounded by sugar. Hubble has spotted an ancient galaxy that shouldn't exist. Experience one (spectacular) day in orbit around Jupiter. 10 Moons Every Person Should Know. The proper name of our satellite, in English, is The Moon. I don't really see the problem acknowledging this.
Luna is the Latin, from Roman times, tied to a moon goddess. None of us are Roman. Old English was mone.. German is Mond.. If germanic languages aren't your thing, then I acknowledge that. There's no particular reason why the Moon needs to be named from germanic roots, or Latin, or Greek for that matter. For the record, my daughter's name is Luna. Great daughter name, JazzCat! The Most Dangerous Places in the Solar System. Even so, some guy will sell those places to chumps in the future. David Mamet will update the film Glengarry Glen Ross to Venusian Estates Mons Venus: Blake: You certainly don't pal, 'cause the good news is - you're fired.
The bad news is - you've got, all of you've got just one week to regain your jobs starting with tonight. Starting with tonight's sit. Comet discovered with ocean-like water inside of it. The crazy life and crazier death of Tycho Brahe, history's strangest astronomer. A couple of #corrections : That would be King Frederik II, not Friedrich. For hundreds of years, Danish kings have alternated between Christian and Frederik, with a few detours like Queen Margrethe I and II. Also, Hamlet was based on royal scribe Saxo Grammaticus' tale Amled by way of a French version (and maybe the missing play known as Ur-Hamlet).
Saxo probably adapted it from an oral tale in the early 1200s, so no Tycho there. Though of course the alleged Brahe affair may have inspired Shakespeare to pick it up, I don't know. I did not know about the magical midget or the elk, fascinating stuff! Flagged @Norseness: Well, Friedrich *is* the accepted German rendering to be fair, and it's what was used in the source I worked from. I actually was aware of Grammaticus's earlier work, but I'm not suggesting Hamlet was a wholecloth retelling of a possible Brahe affair. How the Universe Got its Infinite Darkness. Dark star clusters are like regular star clusters...except full of black holes. What's going on with these mysterious, ultra-red galaxies? 10 Things To Keep In Mind On Your First Trip To Low Earth Orbit. How alcohol is formed naturally in space. A mind-boggling infographic of all the missions from Earth to Mars, and where they wound up.
It wasn't ESA's Beagle 2 (Which failed for other reasons.), it was NASAs Mars Climate Observer. Specifically, the flight system software on the Mars Climate Orbiter was written to calculate thruster performance using the Newtons (N), while the ground crew was entering course correction and thruster data using Pound-force (lbf): This was always something that pissed me off mightily. Were I Chief Dictator and Emperor for life of the United States, I'd institute a death penalty for anyone caught using the traditional measuring system in casual speech or in any form whatsoever and I'd spend billions to destroy all evidence that such a system ever existed in our country.
This is why it's a good thing I am not king. SExpand They just need some initiative. The Earth has a heartbeat we can see from space. Most important scientific study ever: What about farting astronauts? Neil deGrasse Tyson admits it was creepy to discover he was a meme. Saturn's moon Enceladus is the perfect extraterrestrial ski resort. Canvassing the Universe: How Artists Create Scientifically Accurate Images of Faraway Worlds. The First Ever Star With Spiral Arms.
A Star with Spiral Arms. A Star with Spiral Arms Oct 31, 2011: For more than four hundred years, astronomers have used telescopes to study the great variety of stars in our galaxy. Millions of distant suns have been catalogued. There are dwarf stars, giant stars, dead stars, exploding stars, binary stars; by now, you might suppose that every kind of star in the Milky Way had been seen.
That's why a recent discovery is so surprising. The name of the star is SAO 206462. When they took a closer look at SAO 206462 they found not planets, but arms. The arms might be a sign that planets are forming within the disk. "Detailed computer simulations have shown us that the gravitational pull of a planet inside a circumstellar disk can perturb gas and dust, creating spiral arms,” says Carol Grady, an astronomer with Eureka Scientific, Inc., who is based at NASA's Goddard Space Flight Center.
Grady revealed the image to colleagues on Oct. 19th at a meeting at Goddard entitled Signposts of Planets. Author:Dr. Watch the first human/humanoid handshake in space! I was watching this live, and when they showed R2's POV, I was saddened by all the white spots all over the image, which weren't there 3 months ago when they did the first movement tests. Over the years, downloading all the coolest images from Shuttle missions to the ISS, I'd notice those spots on pics taken by the Expedition crews, and suspected that it had some'n to do with cosmic rays or some such doing a number on the CCDs over time.
But I never researched it until just now. Turns out I was right: According to an article on [ConsumerTraveler.com] (the link to which Gawkerkraken won't let me post)... "Can gamma radiation kill pixels of digital cameras? Absolutely. This has been known for a long time. NASA’s been using Nikon digital cameras in space for years. A NASA spokesperson has said, "The space environment (both inside the vehicle and on spacewalks) is tough on the electronic cameras. I sure hope GM planned for this, and made those image sensors replaceable! Spiral Arms Point to Possible Planets in a Star's Dusty Disk. Spiral Arms Point to Possible Planets in a Star's Dusty Disk A new image of the disk of gas and dust around a sun-like star is the first to show spiral-arm-like structures. These features may provide clues to the presence of embedded but as-yet-unseen planets.
Two spiral arms emerge from the gas-rich disk around SAO 206462, a young star in the constellation Lupus. This image, acquired by the Subaru Telescope and its HiCIAO instrument, is the first to show spiral arms in a circumstellar disk. The disk itself is some 14 billion miles across, or about twice the size of Pluto's orbit in our own solar system. (Credit: NAOJ/Subaru)› Larger image | Unlabeled version "Detailed computer simulations have shown us that the gravitational pull of a planet inside a circumstellar disk can perturb gas and dust, creating spiral arms. The newly imaged disk surrounds SAO 206462, an 8.7-magnitude star located about 456 light-years away in the constellation Lupus. This is the binary message we sent out to aliens 38 years ago.
How do we measure the vast distances of the Universe? Actually for really huge distances, the distances between galaxies for example, the parallax generated by the orbit of our planet just isn't large enough to measure things accurately. Parallax is really only useful for measuring the distances of nearby stars and is really only good to about 300 light years or so. But for really huge distances, hundreds of thousands, millions or billions of light years, we need something astronomers call a "standard candle. " To measure distances to nearby galaxies we use stars that vary predictably in brightness, specifically a type of star known as a Cepheid variable.
Around the turn of the last century, the astronomer Henrietta Swan Leavitt discovered that the longer the period of variation of a Cepheid variable, the greater its luminosity. Another astronomer, Harlow Shapley, then was able to correlate the brightnesses of Cepheids with those of known types of ordinary stars, tying Leavitt's relative distance scale to an absolute one.
