Small Asteroid to Do a Close Flyby of Earth

by Leave a Comment

2012 DA14 is a small asteroid that is going to be flying past Earth on February 15th. The asteroid was discovered in February of 2012 by astronomers at the La Sagra Sky Survey. 2012 DA14 will be so close to Earth when it passes us that it will be within the Earth’s geosynchronous satellite ring, that’s pretty close. That distance is where some communications satellites reside, however it will be far above most other equipment and therefore will be a relatively low risk as it passes Earth at a blazing speed of 17,400 mph.

NASA will be taking advantage of this close approaching asteroid by studying it as it passes us.  2012 DA14 isn’t every large, it’s approximately 150ft across and won’t be visible by the naked eye when it passes us, but it should be visible through a telescope.

We could see an Amazing View in the Sky Late 2013

It’s been an exciting time for those of us who like to keep our eyes on the sky. We have seen new developments on Mars, large asteroids get uncomfortably close to our planet, discovered distant planets that are in the habitable zone, and now a newly discovered comet, ISON may give us quite a show in the last few months of 2013.

As the comet gets closer to Earth it could become one of the brightest objects in the night sky, possibly even brighter than the Moon. Some say that ISON could possibly be visible during the day. This would be one of the brightest comets to appear in Earth’s sky in many generations, if it can hold together. There is a chance that as the comet gets closer to the Sun, it may break up and be much less spectacular. The comet will pass within a solar diameter from the Sun in November of 2013.

Hopefully the comet will hold together allowing us to  see a good show.

 

Another Cosmic Catastrophe Avoided

It seems that we have survived several “end-of-the-world” scenarios but now you can add another reason to celebrate to your list. Another massive asteroid named ‘2011 AG5’ was expected to possibly hit Earth sometime around the year 2040. The asteroid was discovered early in 2011 and ever since we have been keeping track of it’s movement to see if it really could be a world-ender.

Space is a massive place and it can be truly difficult to pinpoint whether or not a single chunk of space rock will hit Earth, but University of Hawaii at Manoa astronomers along with the help of NASA, can safely say that the asteroid is not on a collision course with Earth.

It’s good to know that somebody is watching the skies above us. Now we can only hope that when we are in the path of a giant, we can do something about it. There are a few methods being drawn up about how to avoid an impact. Some of these ideas include crashing spacecraft into astroids to alter their course and steer them away from our planet. However, there are not any solid plans in place at this time to help avoid such impacts.

If there are any space projects that are going to be put together, you would hope that one of the top priority missions would include saving our planet. I would like to see missions that focus on landing on asteroids and studying them, with the ultimate goal being to understand how to alter their trajectory. It sounds simple enough but it takes a lot of force to move these giant and all of this would have to be controlled over long distances. Again, it’s a case of us knowing so much but knowing so little. For now it seems that we have a little more time to figure things out, let’s hope we do before we absolutely have to.

Big NASA Discovery On Mars? Not So Much

by Leave a Comment

About a week ago we received news that NASA was possibly on the brink of a major discovery, in fact it was mentioned that it could be for the “History Books”. Well, unfortunately it doesn’t seem like were going to get that kind of news from Mars anytime soon.

This discovery that apparently never happened is being described as a “big misunderstanding”. Here is the original report that I read from NPR. Planet Mars Viewed From Space

“Grotzinger says they recently put a soil sample in SAM, and the analysis shows something remarkable. “This data is gonna be one for the history books. It’s looking really good.”

“Grotzinger can see the pained look on my face as I wait, hoping he’ll tell me what the heck he’s found, but he’s not providing any more information.”

This was from an interview between science correspondent Joe Palca and scientist John Grotzinger. Apparently, what were being told now is that John meant to say that the mission in it’s entirety is historical and that in the next couple of years we expect to make great discoveries.

Something sound a bit strange here? This was big news that made it’s way quickly around the world and that means NASA had to have heard it too. The big question here is if NASA did hear this report earlier then why didn’t they try to correct this earlier?

They were still sampling soil at the time of the interview and were anxiously waiting for results, but apparently they weren’t “History Worthy”. Either way you look at this, it’s still a bit of let down. I guess we will just have to keep our hopes up for future discoveries on Mars.

Possibly the Most Distant Object in the Universe and Looking Into the Past

by Leave a Comment

NASA has recently discovered what they think is the most distant object to ever be observed. This object is actually a galaxy named MACS0647-JD and it’s so far away that normally we wouldn’t be able to see it, even with our best telescopes. So, how are we able to see it then? Well, we lucked out, we got a little help from a cluster of galaxies known as MACS J0647+7015. Large celestial objects like galaxies have such large gravitational influence that they can actually distort and bend light passing near them. In the case of MACS J0647+7015, NASA was able to use this gravitational distortion as kind of a deep space magnifying glass. This effect is what enabled NASA to capture the light of this distant galaxy.

The light of MACS0647-JD has taken nearly 13.3 billion years to reach Earth. We are essentially looking at an object from the theorized beginning of the universe (the big bang). This amazing discovery actually gets me thinking about the distances between objects in space and how long it takes for light to travel between them.

What if we could somehow instantaneously appear 65 million light years away from Earth, and what if we had a telescope with us that was capable of zooming in all the way to the Earth’s surface. Would we see dinosaurs walking the Earth? Theoretically, yes, we should. This raises some fun ideas about what’s possible in the universe. What if we just went a fraction of our first trip away from Earth? Perhaps we only go far enough away to witness the early  beginnings of human civilization and maybe we could just get it all on video. This video would be our exact history, nothing unchanged or lost from our true story. How amazing would that be?

Assuming that in our hypothetical world we can travel to almost any distance, we could actually watch the beginning of our solar system. We could know truly how the Moon was formed and perhaps even watch our solar system form, maybe even watch the Milky Way form. Of course we would need to somehow move our camera closer to the objects we are observing at a relatively quick rate in order to watch the creation of large objects like the Milky Way form in a reasonable amount of time, basically a galactic time lapse. Just a little food for thought.
