Things to See in 2008
2007-12-23 18:03:00 There's a bunch of cool stuff that is going to be going on this upcoming year in 2008 . A couple notable things are:Comets - There will be quite a few comets coming around in 2008. Four of these will likely be visible with binoculars. 8P/Tuttle will remain visible for awhile. For a complete list of comets, check resources at aerith.net and the Institute of Astronomy to see what we can look forward to in 2008.Planets & Moon - Look forward to many solar and lunar eclipses. Also check out the many planets coming into opposition (their closest approach to Earth) and conjunctions (in which planets appear very close to each other). A full list of expected phenomena can be found at Sea and Sky.Asteroid Events - Any dedicated asteroid hunters out there can check out Poyntsource for a complete list of all global asteroid events. This site even let's you import information into Google Earth.Meteor Showers - According to the International Meteor Organization, " The meteor year ahead start... More About: Things

Tunguska-sized Asteroid Misses Earth; Sets Sights on Mars
2007-12-22 15:07:00 On November 20, 2007, NASA-funded observers discovered an asteroid, subsequently named 2007 WD5, after it had made its closest approach to Earth at 4.7 million miles. In terms of NEOs (Near Earth Objects), this is a very close call.While we may be out of the woods, Mars certianly is not. At 5:55am EST on January 30, 2008, it is scheduled to pass within a mere 30,000 miles of Mars. This means there is at least a statistical probability of 1 in 75 that it would collide.This would be an event the size of Tunguska, or larger. It would slam into the surface at more nearly 28,000 mph, create a crater more than a half mile wide, and release more than three megatons of energy.On another note, notice that the asteroid was discovered after it made its closest approach to Earth. We need to do better than this NASA; you're gonna let another Tunguska or dinokiller through. More About: Sights , Sets , Asteroid

Ursid Meteor Shower
2007-12-20 15:35:00 Referring back to our brief post on Comet 8/P Tuttle I actually forgot something very important about that comet; we are only two days from passing through the debris left along the path of the comet. The radiant will be in the Little Dipper (Ursa Minor), near Polaris.The Ursid meteor shwoer has been quite dull in the preceding years, but experts are expecting a much grander show this year because the comet is quickly approaching us. For some pics of this comet, which is as big but not as bright as comet Halley, check out the always cool Flintstone Stargazing, or some more amateur photos at SETI's dedicated website.Unfortunately, viewing conditions will not be ideal for this meteor shower because of the fact that it will be peaking when North America is in the day time, and Europe and Asia will have a bright moon, obscuring their view of outburst as well. Suggestions for successful viewing on SETI's website include blocking the Moon with an obstruction such as a telephone pole and... More About: Shower
Sorry for Slow Postings

Comet Visible with Binoculars
2007-12-17 20:47:00 While everyone is still checking out 17/P Holmes, it's easy to forget another comet is passing through. Not the biggest or brightest of the comets, but still a nice view if you've got some nice equipment; even a pair of 10x50 binoculars will do.Check out Sky and Telescope's Observing blog for more detailed information and charts to help you locate it.I found a new (to me) astronomy/astrophotography blog called Flintstone Stargazing, and its really cool. Check it out; this guy even has some new pics of Comet 8P/Tuttle from this year like the one to the right!EDIT: Flintstone Stargazing rocks. It's going on the blogroll! More About: Visible
Mars Comes Closest to Earth Tomorrow
2007-12-17 20:03:00 Mars will be at its closest point in it orbit to Earth tomorrow. Mars already is an extremely impressive object with its hue very easily distinguishable as red.Courtesy of Sky & Telescope Observing Blog, we have this handy chart to help us plot Mars' position in the sky, though it's really a formality at this point since it is so easily visible. Look to the constellation Gemini, and it should be easily visible as it is by far the brightest object in that section of the sky.On an astrophotography note, I've found that Mars is notoriously difficult, at least for me, to photograph. I seem to get lots of streaks, trails, and other problems. I will be getting my gear out shortly to see if I can get a good Mars shot as I add Taurus and Gemini to my constellation list.Check out the post at Sky & Telescope for more detailed information on what telescope, filters, etc. will give you the best view of Mars.

Hotspots on Enceladus
2007-12-14 00:46:00 Hot spots on Enceladus have lead scientists to believe that it might be less than dead than previously thought, as outlined by William McKinnon in his presentation "Cold Fire: The Geology and Geophysics of Enceladus," on Dec. 10, 2007, at the Fall Meeting of the American Geophysical Union in San Francisco. There is clear evidence now that the icy satellite of Saturn in geologically active. Plumes of ice and vapor are being ejected into the atmosphere, and for this to happen, the temperature has to bee at least 100 degrees C hotter than previously thought.Enceladus actually isn't cold enough for this to happen, however, a "hot spot" near the south pole is. The thought for this mechanism, similar to the oceans of Europa, is the gravitational pull of Saturn on the moon causings the crust of water ice to rub along fault lines, creating enough firction heat to expel water "smoke" into the atmosphere.Even though water is present, the existance of life is unlikely, according to McKinnon, ...
Odyssey Moon Enters Google X Prize
2007-12-07 15:13:00 Odyssey Moon , a British-based private spaceflight company, is seeking Google 's $30 million X-Prize for successfully landing a rover on the Moon.Headquartered on the tax lenient Isle of Man in the Irish Sea, the company, brainchild of CEO Robert Richards (founder of International Space University), is fixed to win this new age space race.The company consists of many experienced space engineers, and is potentially one of the strongest competitors at this point.The Google X -Prize requires a team to land a rover capable of moving 500 meters and transmitting back video, data, and images to qualify for the entire prize by December 31st, 2012.Richards, confident of his company's ability, has been quoted as saying, "We believe the Google Lunar X Prize goals are achievable. And we do intend to win."They intend to reduce the cost of moon travel "by an order of magnitude."He describes the moon as "an eighth continent rich in energy and resources floating just offshore."

Voyager 2 Approaches Termination Shock
2007-12-06 18:32:00 Astronomers like to make cool names for boundaries in outer space. If you cross the point of no return near a blackhole, it's called the event horizon. However, when you leave the heliosphere of our Sun, it's called the termination shock.The heliosphere is a sphere surrounding the solar system in which the solar wind, electronically charged particles emitted at high speeds by our Sun, slows to subsonic speeds. The solar wind travels at supersonic speeds when it is emitted and eventually slows as it "pushes" against the interstellar medium of plasma, neutral gas, and dust. This boundary is not fixed, meaning it can change depending on certain variables.Since the heliosphere moves back and forth, it is estimated that Voyager 2 will cross the termination shock twice: once in the next month or two and again in the middle of 2008. The spacecraft is now in the outer heliosphere, beyond which lies galactic space.The spacecrafts next big step will be the heliopause: the boundary where the... More About: Shock
How to Get Your Wife Interested In Astronomy!
2007-12-06 16:33:00 Check out the full scoop on Daily GalaxyEver feel like your wife just really could care less about the strength of a magnetic field in a magnetar, the path of a planemo, or the latest discovery of a nova in the constellation Puppis?Well fear not, because there's one astronomical discovery she will be interested in. The star formerly known as BPM 37093, located in the constellation Centaurus, is actually a large, crystallized carbon mass nearly 2,500 miles in diameter. Don't let the big words fool you: this crystallized carbon is basically a gigantic diamond!A diamond this large is literally 10 billion-trillion-trillion carats; the number is so incredibly huge it would be followed by 34 zeroes.The carbon core of white dwarf stars often crystallize into diamonds. This is the largest diamond yet located in the galaxy.That should get some wives interested...Adapted from: Daily Galaxy More About: Astronomy , Wife , Eres
Geminid Meteor Shower
2007-12-06 15:34:00 The Geminid meteor shower is set to peak on Friday, December 14th. The Geminid meteor shower occurs when the Earth passes through a debris cloud left by near-earth object (NEO) 3200 Phaethon, which, interestingly is not a comet, but an asteroid, some theorists think.Asteroids don't normally spew debris into space. The tail of a comet leaves debris sometimes as small as a grain of sand that when they come into contact with Earth's atmosphere become a bright flash of light streaking across the sky: a meteor. So where in the world does the debris that forms the Geminids come from?Some think that the asteroid collided with another NEO that creates a cloud of dust and debris that follows it around in its orbit. Some think that it is actually an extinct comet. The comet's orbit is highly elliptical, like a comets. It comes extremely close to the Sun, twice as close as Mercury, where repeated blasts of solar energy could have reduced it to the rocky comet core we see today.True to astro... More About: Shower
Life's Precursors Found in Titan's Atmosphere
2007-12-01 19:21:00 Despite not having nearly any oxygen at all, the atmosphere on Titan has something very interesting in it: negative ions.These ions act as building blocks that more complex organic molecules form from. Carbon can form using these polycyclic aromatic hydrocarbons, PAHs, which have been mentioned in this blog before on the post Why I Think There's Life on Mars...Check out even more details on the Astronomy Report blog which has an adapted version of the official release by University College London.This makes one think... if Titan has the building blocks for life on it, could there be life on it? I know it rains methane on the moon and has lakes and oceans of methane and that its super-cold, however, what if water was as acidic and destructive to organisms living on Titan as liquid methane is to humans living on Earth? What if the temperature of Earth is as blazing hot to an organism on Titan as the surface of Venus is to us earthlings?Just food for thought! More About: Atmosphere

Exciting New Fusion Technology
2007-12-01 17:23:00 Currently still in its R&D phase is Bussard inertial electrostatic (IEC) fusion. This exciting form of fusion can be used to power spaceships with amazingly cheap costs and extremely short travel times. Travel times with this type of fusion include:Travel to Titan would take 75-90 days.24 hours to lunar orbit from low earth orbit.Travel to Mars would take 33-38 days.Amazingly, these almost ridiculous travel times are accompanied by what the general public likes: an equally ridiculous low cost. Cost can be as low as these figures:$200 million of research, development, building, and testing.2 8-gigawatt thermal fusion engines are nearly 100x less expensive than our best systems available today.Check out a the Advanced Nanotechnology Blog for more in detail information. Definitely a must for any aspiring space junkie!I was referred to this site by the always awesome Bad Astronomy Blog. More About: Technology , Fusion

Lights With No Sun
2007-11-30 14:39:00 The ESA's Rosetta, the first ever spacecraft whose destination is a comet, took this picture of the Earth at night. Large cities are clearly visible as mankind's presence on this planet is clearly visible-- even when the Sun is not. Rosetta has a super complex trajectory is making its course to comet 67P Rosetta. This includes not one, but three gravity assist maneuvers around Earth and another around Mars. This truly will show how efficient current technology can accurately predict the course of our probes.Once reaching comet 67P Rosetta, the craft will remain in orbit with the comet during its journey to and from the Sun. In a nutshell, Rosetta will ultimately tell us what comets are made of, why they are different (or the same) as other intersolar materials, and give us a better idea of what the surface of a comet actually looks like.Interesting mission to be sure, and likely it will present us with new information while verifying what we already know about comets.

A Different Kind of Venus...
2007-11-29 16:35:00 Venus recently seems to be a hot topic, and for good reason: the ESA's Venus Express probe has been churning out some very interesting data. You can even check out our most recent Venus post titled The Oceans of Venus for even more information. We know that the solar wind interacts with the hydrogen in Venus' atmosphere, causing it to forever be lost in space. More recently, we have discovered that oxygen has been escaping the atmosphere all along as well. This is an exciting discovery because since the structure of water, obviously made up of both hydrogen and oxygen, has been escaping into the atmosphere, with enough data, we can reverse this process mathematically and determine how much water has escaped into space.Venus expert, David Grinspoon, thinks the amount of water is indeed significant: nearly as much as the oceans of Earth (Source: Daily Galaxy). He actually authors a book called Life on Venus, in which he states that 4 billion years ago, when the Sun's heat output wa... More About: Venus , Diff
