Thermonuclear Behavior of Unique Neutron Star Detected
Solar Storm Strikes Earth

A series of solar storm burst from the sun this week, sending a flurry of electrically charged particles into Earth’s magnetic field. Thus far there has been no real damage caused by the storm, but more are on the way. The Sun is currently partially through an 11-year storm cycle which can cause problems here on Earth.
The solar activity from our Sun has changed the shape of the Earth’s magnetosphere, resulting in a geomagnetic storm. These storms will likely cause very noticeable side effects on Earth. Solar storm forecasts predict very strong solar wind activity in 2013 before the storms die down.
This article was interesting to me because I often hear about solar flares and things like that. I was hoping this article would be a little more informational about solar storms, but it interested me nonetheless.

GJ1214b
I found this article to be cool, but also very vague. The astronomers at Harvard are still learning a lot more about the planet and are just sharing their findings as they go along. The cool part is how dense this planet made of water is. We will hear more about it soon, I'm sure!
Herschel Finds Oceans of Water in Disk of Nearby Star

Scientists have found cold water vapor enveloping a dusty disk around a star named TW Hydrae. This star is about 10 million years old and realtively close to us at only 175 light years away. The disk itself is about 200 times bigger than the distance between the Sun and Earth. As the new solar system evolves, icy comets will most likely deposit all of their water that they contain on to newly created worlds giving rise to oceans. Astronomers think that this discovery could give light to how planets with abundant oceans could form.
Winds of a Stellar-Mass Black Hole
Astronomers using NASA's Chandra X-ray Observatory have found the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. The winds are moving at ab
out 20 million mph, nearly 10 times faster than ever previously recorded. The black hole is a binary system in which a sun-like star orbits it. It is found in the bulge of the Milky Way galaxy, about 28,000 light years away from Earth.

Atmospheric Oxygen Within the Solar System?
Make no mistake, Dione's atmosphere is weak. As interesting as the mental image is, we could not survive there unaided. But if water and oxygen can exist in places like this, it's entirely possible that they are more common than we originally thought. This carries a lot of significance for the fields of human space travel and habitable exoplanets. Perhaps we will eventually find a planet that could be colonized with little more than an adequate space ship!

Understanding the Beauty of Far Away Galaxies
This is a spiral galaxy, the most common variety of galaxy there is. ESO 510-13 is it's name, and I learned of it from this article.
At first glance, it looks like a sort of thin, astronomical cuttlefish, or a trail of stardust left behind after the passage of some unknown object. I wouldn't have guessed it was a spiral galaxy before taking this class. In my mind spiral galaxies have always looked like the one below.

Geologically Active Moon
Some think that the moon is dead, but new studies form NASA's Lunar Reconnaissance Orbiter proves that the moon is both shrinking, and expanding at the same time. This doesn't make much sense, but it is shrinking in some areas, and expanding in others. In the early stages of a planets evolution, most of the planets melted and reformed. However with the moon, only the outer layer melted and reformed, causing the center to still be very hot. "We think the moon is in a general state of global contraction because of cooling of a still hot interior," said Thomas Watters. Due to the changes in the moons surface, narrow trenches are formed called Graben. There are a handfull that have been found on the moon so far. It is estimated that the distance between the center and the surface shrunk by 300 feet.

Safe & Sound... For Now

atmosphiric oxygen found on dione, saturns moon

Cassini, a NASA Space craft sniffed oxygen around saturns icy moon dione for the first time, creating the possibility there could be an atmosphere, although the oxygen ions are few and far between.
i thought this was cool because Dione would be another celestial body joining the ranks of planets with atmospheres, like eath, venus reah and possible mars.

A cluster of galaxies Dark matter core cannot be explained by current theories
This is issue is a very sensative thing. On one hand if we are wrong about how dark matter works to a high extent then it could start to affect other theories we have come up with and show us that we know very little about our universe. On the other hand this anomaly cannot easily be explained by informationwe currently have on the subject, which is very little because of dark matters properties it is very hard study. I personally think more data should be gathered before we really start to form opinions or hypotheses on the subject

Tornado on the Surface of the Sun

Source: A Tornado on the Sun via NPR
The Sun is a very active star with a history of spewing radiation and atomic particles into space. In early February, NASA recorded a video of a tornado of plasma the size of Earth spinning around the Sun's magnetic fields. The tornado generated gusts up to 300,000 mph; to put that into perspective, our strongest tornadoes can only generate up to 300 mph gusts. Click to see video.
The Sun's weather will be a fascinating thing to observe and see change in. The Sun's weather has real world effects for the inhabitants on Earth, and I think it would be really cool if the general public paid more attention to the everyday phenomenons that occur on the surface of the Sun.

China and India to create world's biggest telescope

China and India have a catapulting to the forefront of astronomy research with their decisions to join as partners in a Hawaii telescope that will be the world’s largest when it’s done built later this decade. China and India will pay a type of share of the construction cost expected to top $1 billion for the thirty meter telescope at the summit of Mauna Kea volcano. They will also have a share of the observation time. It’s one of the first advanced telescope in which either nation has been a partner. They said that this will represent a quantum leap for the Chinese community Shude Mao, professor of astrophysics at National Astronomical Observatories of China. Thirty Meter Telescope’s segmented primary mirror which will be nearly 100 feet long. The telescope known as TMT, it will be able to observe plants that orbit stars other than the sun and enable astronomers to watch new planets and stars being formed. It should also help with scientists see some 13 billion light years away for a glimpse into the early years of the universe

The Earth is unique amongst the terrestrial planers in having a large satellite, which it relative to the Earth has the largest mass of any satellite parent system. They said that there’s numerous lines of evidence indicate that the Moon was derived from the Earth as the result of a singular impact event that soon after initial formation of the Earth. As a result that they got of subsequent evolution of the Earth and the emergence and development of life has been strongly influenced by the presence of the Moon.
The Moon also raises tides in the solid body of the Earth and in the past, when the Moon has orbited much closer to the Earth than at the present, the tides are estimated to have produced displacements in the Earths solid surface of up to a kilometer. That this would haved produced intense stress and deformation within the Earth which, coupled with decaying heat of accretion and the higher content of the radioactive U, Th, and K elements would have greatly promoted melting of the early earth.

Ultra-Fast Outflows Help Monster Black Holes Shape Their Galaxies

A new type of outflow that appears to be powerful enough to link the mass of a galaxies central black hole and the velocity of stars was identified by NASA's Goddard Space Flight Center's Francesco Tombesi. The link between these two entities has puzzled astronomers and scientists for years.
Most Galaxies house an incredibly massive black hole at their center, but galaxies that contain black holes with even more mass also contain large "bulges" that contain stars that move faster than average stars. Before now, there was no plausible explanation for this behavior.

A Dying Star with Wind in it's Hair: Abell 31

Not too long ago astronomers came across a Planetary Nebula that looked like it's hair was blowing in the wind. Interesting right? A Planetary Nebula is a cloud of gas formed by a dying star that expels winds of matter outward; first very slow but then speeds up. The photo of Abell 31 was taken with a 0.9 meter telescope in Arizona on Mt. Lemmon. It took a long 21 hour exposer that used various filters. Why are we just noticing this now? Its because the nebula is very faint, which makes it difficult to see, which makes it easy to miss. Usually Planetary Nebulas are very symmetrical, but as you can see, this one is not! Why is that? This is because this Nebula is actually in motion, traveling through space(directly downward toward the bottom of the frame). The red gas is hydrogen, and the blue is oxygen. Although you cant see it, the oxygen is most likely present all around the nebula, but the center is only lit up because it is closer to the White Dwarf. Astronomers have found that it has about half the mass of the Sun, meaning it probably started out life as a star with about twice the mass of our sun, and lost the rest as it aged and blew the winds. This star started dying approximately 130,000 years ago. When this star died and became a White Dwarf, and this White Dwarf core is very small, approximately 4 times the size of earth. Thats pretty small. Although this core is puny, it is HOT, at around 150,000 degrees F. This nebula is the opposite, it is huge, and on a clear night you can see it, its about half the size of a full moon.

Mars Rover computer reset bug fixed

The mars rover has been having a memory problem with the registers (data holding locations) causing it to reset. The cause for this is a flaw in the the previously unknown design idiosyncrasy in the memory management. To fix this they had to change the way that some of the unused registers where configured. The error was first discovered on Nov. 29, 2011, three days after launch, during use of the craft's star scanner. After narrowing down the problem they where able to fix the problem and confirming it after running billions of tests.

Kepler Discovers 11 New Planetary Systems

Because these systems are so compact the gravity of the exoplanets can effect each other, causing something called Transit Timing Variations. This is when a planets orbit is either speed up or slowed down by anothers gravity, Kepler is helping us understand how this works in these new systems.
The discovery of these new systems are published in four different papers in the Astrophysical Journal and the Monthly Notices of the Royal Astronomical Society, and on Nasa.gov.
"Prior to the Kepler mission, we knew of perhaps 500 exoplanets across the whole sky. Now, in just two years staring at a patch of sky not much bigger than your fist, Kepler has discovered more than 60 planets and more than 2,300 planet candidates. This tells us that our galaxy is positively loaded with planets of all sizes and orbits." - Doug Hudgins, Kepler program scientist at NASA.

Snoopy in space?

your probly thinking "hold up a sec! I thought snoopy was a world war 1 flying ace." well heres the thing. in the 1960's everyone in the US was really into the space race. so Charles Schulz converted Snoopy's dog house from a world war 1 airplane in to a rocket ship. in the comic he actually beat the USA and the Russians to become the "first beagle to the moon!"
Now reacently an exibit on snoopy and his accotiation with NASA will be apearing at the Charles Schulz Museum in Santa Rosa, Calif. for the purpose of celebrating the 40th anniversary of the Apollo 10 mission.
In May 1969, Apollo 10 astronauts Gene Cernan, John Young and Thomas Stafford traveled all the way to the moon for one final checkout before the lunar landing attempt.
Because the mission required the lunar module to "snoop around" scouting the Apollo 11 landing site, the crew named the lunar module "Snoopy." Naturally, the Apollo command module was labeled "Charlie Brown."
The astronauts carried paintings of the duo on their spacecraft, with Charlie Brown in space coveralls and Snoopy in his Flying Ace scarf. They used the paintings to calibrate the cameras used for the first live color telecasts from space.
Apollo 10 astronauts Cernan and Stafford will join recovery team members Chuck Smiley and Wes Chesser at the museum on Jan. 31 to kick off the exhibition. Also attending: Jamye Flowers Coplin, a NASA secretary who was photographed bringing Snoopy to see the crew off The exhibit will feature a one-third scale model of the Apollo command module from the Johnson Space Center, an Apollo-era flight suit, the actual image of Charlie Brown that was flown aboard Apollo 10, and a special children's area for creative play.
Snoopy's connection with NASA actually began before Apollo 10. In 1968, NASA chose the beagle as an icon who would quote: "Emphasize mission success and act as a 'watchdog' for flight safety."
Established that same year, the agency's "Silver Snoopy Award" is considered the astronauts personal award, given for basically trying really really hard. Award winners receive a sterling silver Snoopy lapel pin flown in space, along with a certificate and letter of appreciation from NASA astronauts. Fewer than 1% of the workforce is recognized with a Silver Snoopy annually, making it one of the most prized awards in the industry.pretty cool eh?

Planets like Tatooine..

Illustration of Kepler 35b |
I find this article to be very interesting. Because we have found three of these circumbinary planets, they are considered to be a new class of planetary systems. Scientists will now start to compare the differences of the planets and really look in depth at these special planets. I think its really cool that circumbinary planets would have two sunsets and two different sunrises every single day. It is also amazing that if it was the right temperature for life to live on, with the liquid water, life could live on this planet. I would love to live on a planet with two different sunrises and sunsets. I hope that Kepler finds even more of theses planets, and maybe someday, astronauts will be able to go and see the beauty.
