  • Are we boldly going places?

    Bill Andrews
    6 Nov 2009 | 11:55 am
    NASA’s done a good job getting us into space, but should it work harder on convincing people why that’s a good idea? NASA photoChances are you’ll recognize the phrase, “To boldly go,” as part of the monologue introducing each episode of Star Trek. I’ve heard it called the most famous split infinitive in the English language, and whatever a person’s science knowledge or familiarity with Star Trek, they’ll usually recognize “To boldly go — where no one has gone before.”Jeremy McCarter argues in “Rocket Men,” a story in the November 9 issue of Newsweek, that we need…

    In this artist’s illustration, an orbiter works together with blimps and rovers to explore an unfamiliar landscape. NASA/Jet Propulsion Laboratory photoWolfgang Fink has a dream straight out of science fiction: Instead of sending a paltry robot or two to distant planets, scientists should send multiple expendable robots. Robots that can talk to one another and adapt to unexpected events. Robots that can think. Creepy as that might sound to some, it’s really just the next step in space exploration, according to Fink, visiting associate in physics at the California Institute of Technology…

    OK, I know that some people see the face of their religious icons in random things. I’ve written about this a zillion times. And I know that sometimes it’s just pareidolia, our tendency to see faces in random objects. And I know that people will think it’s a miracle, when really it’s the end-product of thousands of generations of the evolution of our pattern-seeking abilities. But then there’s stuff like this: a guy is "clueless" about how the face of Jesus appeared on his truck window, and why it persists day after day. Oh, I have a clue. It’s…

    Looking for something to do this weekend, and for the next month? Are you anywhere near New York City? Then I am very pleased to let you know that a group of artists there have created an exhibit based on my book, Death from the Skies! The exhibit is hanging at the ABC No Rio site, and runs from now until November 25 (actually it started last week). The viewing times are Sundays 1:00 – 3:00pm and Wednesdays & Thursdays 4:00pm – 7:00pm. This is very cool, and I am deeply honored they based their work on my book. I was contacted by artist Brian George about it some time ago.

    The hi-res Lunar Reconnaissance Orbiter’s camera captured a pretty cool image of a (what I’m guessing is an ancient) landslide on the Moon. Check this out: [Click to embrobdingnangate.] The slide is down the steep slope of a crater called Marius, located in Oceanus Procellarum, a vast smooth-surfaced area on the Moon (generally called "maria" — singular is "mare" — and easily visible to the naked eye). The crater itself is pretty old; the floor is covered with the same smooth surface as the mare around it, so it predates Oceanus Procellarum which we…

       Solar Cycle 24 has been very calm and mostly uneventful. We have seen one of the longest minimums in recorded history. And solar observers have not had much to report. This weekend, that all changed. During Oct 23-25, Sunspot 1029 grew into quite a nice display. B- and C-Class flares associated with Sunspot 1029 could be seen, and the complex grew quickly. If the growth continues, Sunspot 1029 may become one of the largest, if not the largest, sunspot complex for the year. (more…)

    Confessions of an Alien Hunter, by Dr. Seth Shostak of the SETI Institute, is a look at SETI from the inside.  In addition, Dr. Shostak talks about who, and what, our first alien contacts may be (aside from microbes or pond scum).  You know me; I would be excited out of my tiny little mind with a microbe. The hope, the belief, that we are not alone in the universe has been with us since we could envision ourselves as “self”.  We have always looked to the sky and wondered.  Science now tells us that there must be other life; the universe is simply too big for there not to be. …

  • Early Galaxy Pinpoints Reionization Era

    Nancy Atkinson
    6 Nov 2009 | 11:17 am
    Astronomers looking to pinpoint when the reionozation of the Universe took place have found some of the earliest galaxies about 800 million years after the Big Bang. 22 early galaxies were found using a method that looks for far-away redshifting sources that disappear or "drop-out" at a specific wavelength. The age of one galaxy was confirmed by a characteristic neutral hydrogen signature at 787 million years after the Big Bang. The finding is the first age-confirmation of a so-called dropout galaxy at that distant time and pinpoints when the reionization epoch likely began.
  • Space Junk May Force Crew from ISS

    Update #2, 5:30 pm: NASA has now said that after further analysis, the space debris they have been tracking no longer poses any concern or threat to the ISS. Everyone can rest easy tonight! The piece of debris was only 5 cm long, and will not pass within the "pizza box" zone around the station (0.75 x 25 x 25 kilometers) that calls for an alert. A hard-to-track piece of space junk may come within a half a kilometer of the International Space Station later today, and NASA managers are considering asking the crew to board the docked Soyuz capsules as a precaution.

    What does the third week of October mean to us? Yes, as indicated by the title, the earth is passing through the debris stream left by the Halley Comet. As a result, earthlings get the chance to watch the spectacular Orionids. The rate is about 60 meteors per hour. As usual, the best time to watch meteor shower is before the dawn.  This year is especially good since the moon is almost new, no moon light will interfere the show. As you get under the night sky, you will notice that the winter constellations (for northern hemisphere) are up which makes the sky spectacular again. For example,…

    6 Nov 2009 | 6:24 pm
    In the morning, Jeremy Tinker (Berkeley) led our group meeting with a discussion of information about galaxy evolution from clustering. In the approximation that we know the dark matter model, the relationship between galaxies and dark matter can be parameterized and then the observed galaxy—galaxy clustering puts constraints on how the galaxies could possibly form and evolve. He has some counterintuitive results, from the fact that at intermediate redshift, the large-scale clustering of red and blue galaxies is very similar. In the afternoon, Marc Kamionkowski (Caltech) gave the Big…

    5 Nov 2009 | 1:17 pm
    As my loyal reader knows, I have no fear when it comes to models with huge numbers of parameters; indeed the ubercalibration project is effectively a fit with hundreds of millions of parameters, and we can prove that we got the global optimum (in the sense that we made sure the problem is guaranteed to be convex). Today Roweis pitched a generalization of all this, in which one creates a very flexible linear model space, where parameters are tied to or in a hierarchy of meta-data, such that some parameters are tied to, say, the date, some to the airmass, some to the seeing, some to the camera…

That is, what can you do if you get a snapshot of a few orbits, but you only get the angular shapes of those orbits? We went back and forth a bit between the answer everything and the answer nothing. I think it is the former, but of course it will depend strongly…

It is an integral part of the Constellation program which is designed for replacing the current space shuttle fleet and moving their manned space program to the moon and beyond. Currently, the Ares program is so far behind schedule that there is very little chance of making it to the moon in 2020 or even…
  • LOOK OUT CHICKEN LITTLE--THE SKY IS FALLING

    26 Oct 2009 | 1:40 pm
    There is a report out of Latvia, a small country in the northern Baltic, about a large object falling to the ground near the small city of Mazsalaca leaving a crater 66 ft in diameter and 33 ft deep. Almost as soon as the report surfaced there were indications that it might be a fake. There were all sorts of theories as to why the report was downplayed with the main one being to cover a weapons test. Just why a small country would need to cover some kind of weapon test is not clear to me but stranger things have happened. Maybe it wasn't the country of Latvia that conducted the test. One…

    I have titled this rant a "Great Public Star Party" and that's exactly what I thought it was. There was a big turnout for the North Texas Skywatch Star party held at Lake Mineral Wells State Park last Saturday night---the weather was very good and there were plenty of folks there with their favorite scope to show the visitors the night sky. And the public did turn out for the show.This particular event, which has been going on for several years, reaches out to a very select group of would be star gazers.

  • Dominating the Autumn Sky: Pegasus

    4 Nov 2009 | 9:44 am
    In November, the nights grow longer and the sky changes rapidly. The Summer Triangle gradually fades into the west, and Orion and the winter constellations have not risen in the east to dominate the night sky. Instead, we see the less prominent (but no less beautiful) zodiac constellations of Capricornus, Aquarius and Pisces in the south, and directly overhead the large constellation Pegasus with the very distinctive asterism "The Great Square" in clear view. The sketch of the constellation Pegasus shown here is courtesy of the Battle Point Astronomical Association.Pegasus is named after the…
  • Close Encounter of the Pleiades and Moon

    1 Nov 2009 | 9:32 pm
    The Pleiades is one of the most beautiful star clusters in the sky. In Autumn it rises during the evening and its distinctive glow shines even for urban dwellers. The Pleiades, also known as M45 (from the Messier Catalog), is a collection of relatively young stars (only 100 million years old!) that shine with a blue color due to their hot temperature. The Pleiades are also known as the Seven Sisters and there is plenty of mythology describing each of the seven sisters. Despite the "Seven Sisters" mythology, most people see six stars when they look out at the Pleiades and describe the shape of…

The Moon, just past first quarter phase, is also speeding across Capricornus and will appear very near to Jupiter on Monday evening October 26th.Jupiter will remain a brilliant light high in the southern sky for the remainder of 2009.

Far too many folk image an object (eg the Crescent nebula) and use software to remove all of the background, perhaps assuming it is noise or gradients. Personally, I prefer to keep it in the image, if it is genuine emission.

    Date: November 2, 2009 Title: Cassini's Deepest Plume Passage: The "E7" Flyby of Enceladus Podcaster: Anne Verbiscer Organization: University of Virginia Astronomy Description: Today the Cassini Spacecraft makes its 7th flyby of Saturn's enigmatic moon Enceladus. The trajectory takes the spacecraft deeper into the moon's icy plumes than ever before, skimming a mere 100 kilometers (62.5 miles) above the jet sources found at the small moon's south pole. (Enceladus itself is only 500 kilometers (or 300 miles) in diameter.) Such a close flyby through the plumes presents the…

    From the USM Southworth Planetarium “Every second in energy abounds” THE DAILY ASTRONOMER November 6, 2009 Quiz: Weather and Space Weather Those of us fortunate enough to reside in the nation’s right earlobe experienced snow on Thursday morning. Some citizens rejoiced at this frozen precipitation, for they revel in the change of seasons and are anxiously awaiting another winter of brisk air and crystalline snows. With the exception of these 3 – 4 people, the rest of us are in a state of lock-jawed distress. In honour of this transition, we offer a quiz about weather…

    From the USM Southworth Planetarium “…and that’s just the half of it.” THE DAILY ASTRONOMER November 5, 2009 The Down and Out of Dark Energy What happened in the beginning…. The prevalent theory is that the Universe took form after the Big Bang, an inflationary event in which matter, energy and spacetime were created. The Big Bang Theory developed after early 20th century astronomers observed distant galaxies moving away from us in all directions. The assumption was that a singular event caused this expansion: an event that we now call the Big Bang, a term coined…

    From the USM Southworth Planetarium “A cohort of kiddlequicks” THE DAILY ASTRONOMER November 4, 2009 Sea God World Stand Still Now that we’re on the subject of planetary motion, it is worth some time to discuss the concept of stationary planets. The term itself seems like an oxymoron, for the word “planet,” derives from the Greek word “planetes,” meaning “wanderer.” Planets earned this name because they exhibit motions independent of the background stars. As we would eventually discover, all planets, including the one on which we live,…
