SpaceTT: Live feed feed of the Moon and Jupiter tonight via Melton Memorial Observatory

While the awesome animated GIF images I posted earlier are fresh in your mind, I would like to bring something else I consider awesome to everyone's attention. My friends at the Melton Memorial Observatory of the University of South Carolina will be hosting a live video feed of their public observing session tonight.

SpaceTT: Finnish astrophotographer's animated GIF images of Elephants Trunk Nebula are mesmerizing

It's no secret - I am a huge astronomy buff. So much so that I even endeavor into the complex realm that is astrophotography. I say "complex" because taking a clear, crisp and vibrant image of the cosmos is quite challenging, and requites many hours to produce a single 2D image.

 

TweakTown image news/2/8/28598_1_spacett_finnish_astrophotographer_s_animated_gifs_are_mesmerizing.jpg

 

Finnish astrophotographer J-P Mestävainio has taken these complexities and mastered them, but he did not stop there. Mestävainio wondered what the Nebula he was photographing looked like in the third dimension and set out to create what can only be described as breathtaking. Seen below is IC 1396 or the Elephants Trunk Nebula.

These animated GIF images are in all actuality an artist interpretation of how he thinks the nebula would appear if passing by. The GIFs are created by adding interpretations and educated guesses based on the formation of the nebula and a rule-of-thumb that brighter stars are closer than darker ones to known data about the nebula, like distance and the location of certain stars around it to create a 3D model of the nebula.

SpaceX to launch Dragon on March 1, will dock with the ISS

SpaceX is set to send their unmanned Dragon capsule to the International Space Station on March 1, where it will launch from Florida's Cape Canaveral Air Force Station.

 

TweakTown image news/2/8/28590_10_spacex_to_launch_dragon_on_march_1_will_dock_with_the_iss.jpg

 

Dragon will launch at 10:10am EST (1510 GMT) on March 1, docking with the ISS a day later. SpaceX's Dragon will be toting 1200 pounds of supplies and scientific experiments to the ISS, and will return to Earth just over three weeks later on March 25, splashing down in the Pacific Ocean, just off the coast of Baja California, bringing with it 2300 pounds of experimental samples and equipment.

 

This will be SpaceX's second contracted cargo mission to the ISS for NASA, and overall, their third visit. SpaceX has a $1.6 billion deal with NASA to make 12 similar flights with their Dragon and Falcon 9 rockets.

The first bionic hand that can feel will soon be here

We all love our consumer technology, but scientific breakthroughs like this are just extraordinary. Later this year, we'll see the first bionic hand that will give an amputee the ability to feel their hand again.

 

TweakTown image news/2/8/28588_06_the_first_bionic_hand_that_can_feel_is_now_here.jpg

 

This will be quite the moment for artificial limbs with sensory perception, where the first man to get the new touch-sensitive bionic hand will be a man in his 20s living in Rome, who lost the lower part of his arm in an accident. The wiring of this bionic hand will be connected to his nervous system, where they hope he'll be able to control the movements of the hand as well as receive touch signals from the bionic hand's skin sensors.

 

This is coming from Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland, where he's also added that the hand will be attached directly to the patient's nervous system through electrodes clipped onto two of the arm's main nerves - the median and ulnar nerves.

Congress to discuss asteroids as a threat to Earth, won't involve Bruce Willis

After multiple space agencies have been tracking the asteroid that fled just past Earth waving hello and goodbye, Russia was attacked by space rocks late last week. The meteroid broke up in our atmosphere, but still crashed into Earth injuring over 1200 people and causing millions of dollars of damage.

 

TweakTown image news/2/8/28587_05_congress_to_discuss_asteroids_as_a_threat_to_earth_won_t_involve_bruce_willis.jpg

 

Because of this, the Science, Space, and Technology Committee in Washington are planning to hold a hearing soon "to examine ways to better identify and address asteroids that pose a potential threat to Earth."

 

NASA have said that the rock that smashed into the Russian city of Chelyabinsk, which is around 950 miles east of Moscow, was around 15 meters in diameter, and it was moving at an astonishing 18 kilometres per second. It lasted around 30 seconds in our atmosphere before it broke apart, and wasn't detected by any Earth-based telescopes. NASA scientists have said that it is virtually impossible for telescopes to see a meteorite that size in the daytime sky.

SpaceTT: Asteroid 2012 DA14 to make closest pass to Earth today at 2:24 PM US EST - hope it doesn't screw with us

Asteroid 2012 DA14, a chunk of space rock roughly the size of a football field, will make the closest pass to Earth ever recorded of a previously known object. At around 2:24 PM US EST the asteroid will pass Earth within 17,200 miles of our atmosphere.

 

TweakTown image news/2/8/28562_1_tonight_asteroid_2012_da14_to_make_closest_pass_to_earth_ever_known_about_in_advance.jpg

 

This close pass comes hot on the heels of an unrelated massive meteorite exploding over Russia yesterday. The meteorite passed over a remote part of Russia and exploded over the town of Chelyabinsk, and injured 500 people when its shock wave shattered the glass in surrounding buildings. You can hear the massive explosion in the video below.

 

 

NASA scientists say that the two events are most likely unrelated, and there is zero chance of Asteroid 2012 DA14 hitting Earth. Those interested will be able to observe tonight's flyby by watching a series of webcasts being held by NASA and broadcast on Space.com (Source #2). Personally I will be outside with my 10" Schmidt Newtonian telescope trying to get a fleeting glimpse of the object.

University of Southern California shows off battery featuring silicon nanowires, holds 3x the energy, charges in 10 minutes

I really can't wait for the day when I can buy a new smartphone with a week-long battery, but it looks like the University of Southern California are working on it, almost like they're reading my thoughts.

 

TweakTown image news/2/8/28525_08_university_of_southern_california_shows_off_battery_featuring_silicon_nanowires_holds_3x_the_energy_charges_in_10_minutes.jpg

 

This technology uses porous, flexible silicon nanowires for the anodes in a lithium-ion battery that would provide the high capacity, fast recharding and low costs that come with the silicon, but without the weaker previous attempts that relied on simpler silicon plates.

 

This would, in a best case scenario, provide us with triple the capacity of today's best batteries, a full recharge in 10 minutes and more than 2,000 charging cycles. This is where I say "shut up and take my money", but the money hitting my screen and falling onto my keyboard is doing nothing. To finish, researchers have estimated that there should be products hitting consumers' hands with silicon-sporting lithium-ion packs in two to three years, which isn't too long at all.

LHC will be down for next two years undergoing maintenance and upgrades

For those science junkies that were disappointed when the Large Hadron Collider didn't manage to end the world by creating black holes, you'll be getting another chance in two years. The LHC will be down for the next two years so that it can undergo maintenance and upgrades to bring it back to peak efficiency.

 

TweakTown image news/2/8/28534_1_lhc_will_be_down_for_next_two_years_undergoing_maintenance_and_upgrades.jpg

 

The device will eventually make its way back online sometime in 2014. At that time, it's expected that the particle accelerator will be operating at up to 14 trillion electron-volts, double the energy it was running at in 2011. Part of the reason the LHC hasn't achieved higher energies yet is due to the helium gas explosion which damaged and delayed the project.

 

This maintenance period will be used to fix that damage, perform maintenance and upgrade the detectors, electronic shielding, and ventilation system.

Your next house could be 3D-printed, would take just three weeks to build

3D printers are the new everything right now, where we've heard about moon bases being 3D-printed, buildings being 3D-printed and even stem cells - what next? Houses. Yes, houses.

 

TweakTown image news/2/8/28517_01_your_next_house_could_be_3d_printed_would_take_just_three_weeks_to_build.jpg

 

A London-based design firm, Softkill, has just talked about their entry into the rat race that is 3D-printed houses, with a structure they claim would take just three weeks to build. From the picture above, it looks like a million spiders have crawled in and just spun a house out of their webs, but this is all part of what Softkill call their ProtoHouse, and will reach the prototype stage by the middle of the year.

 

During an interview with Dezeen, Softkill's Gilles Retsin didn't like the idea of their rival project by Universe Architecture, where he said:

 

We actually don't even consider that a 3D-printed building, because he is 3D printing formwork and then pouring concrete into the form. So it's not that the actual building is 3D printed.

SpaceTT: Astronomers ask public to help name Pluto's two new moons

Recently two more moons were discovered around the former planet Pluto, bringing the total count up to five. Dubbed P4 and P5 for obvious reasons, these two new moons have brought new understanding on how the dwarf planet fits into our solar system.

 

TweakTown image news/2/8/28444_1_astronomers_ask_public_to_help_name_pluto_s_2_new_moons.jpg

 

SETI, the institute that is more so known for its research into discovering alien life, has decided to spice up the bland names given to the newly discovered moons. Beginning today SETI will hold a contest to name the moons. The institute is asking the public to either pick from a list or write in names associated with Hades of Greco-Roman mythology fame.

 

A list of the pre-selected names can be found on SETI's website, which I have listed below in the Source #2 link below. I decided to go with two common names myself - Heracles and Persephone.
