Amateur astronomer. Lives near Portland, Oregon Own Celestron CPC1110 and lucky enough to house it in an observatory. Have done some work with asteroid occultations, meteor shower counts, and currently working on learning astrophotography. Doing the Y!A "Space and Astronomy" thing is a bit of a hobby, along with doing public outreach for astronomy. I do find that well over 90% of the questions posted can be answered by anyone who knows who to do a simple keyword or phrase search. The rest is usually just pointing folks in the proper direction.
Three major medical issues are presented.
Some of these problems won't show up for at least 24 for hours.Astronomy & Space3 years ago
It just might be possible that an asteroid smacked into the Earth with enough force to move debris out past Earth's escape velocity and out to the rest of the solar system. After all, ejected material from Mars and the Moon have been found on Earth. why not the other way around?Astronomy & Space6 years ago
While the graph is meant to be humourful, it does give you an idea of the process involved in identification.
Not a question, but an annoucement. AAS is having its annual meeting this week and is streaming a long series of live interviews with professional astronomers who work either on or with the Hubble or upcoming Webb telescopes. Some really cool information, but I don't know how long the webcast will last.
These are pictures taken by the Lunar Reconnaissance Orbiter, stitched together so that you have have down to 0.5 meter per pixel resolution (or roughly 20" per pixel). Play around with the table of Contents (the stacked squares in the upper left corner) and you can tease out all sorts of information.
Like anything else, astronomical observatories have a life span. Encroaching light pollution, lack of funding, even technological advances can render a once leading observatory into disuse.
Here's a few from around the world -
Just how many Tribbles would it take to fill up your home?
On 19 October 2014 comet C/2013 A1 (Siding Spring) will pass enough to Mars to make an impact a likely possibility. Further observations need to be taken in order to predict the comet's orbit better, but even if it misses, it'll be quite the sight.
27 Dec 2004 a beam of cosmic rays sweeps past the earth. Other than temporarily swamping the detectors on some gamma ray satellites and disrupting the ionosphere for a while, nothing of note happened.
The facts of what happened are truly scary. This burst came from a star quake on a magnetar from across the galaxy (50,000 light years) away. The energy released was equivalent to our sun generating 250,000 years worth of energy in about 1/4 second.
It would saved so much hassle and wasted bandwidth -
It's a month early, but no more Wonder Bread, Ho-Ho's, Twinkies and all those other great empty calorie Hostess treats are to be no more.
Oh, the pain of it all!
NASA's huge crawler transporters.
These two rigs, built for the Apollo rocket system and last used for the space shuttle are getting a retrofit to handle the next generation of heavy lift rockets. Their current weight capacity is 12 million pounds and after the retrofit, they will be able to handle 18 million pounds.
Everything about the crawlers is huge read up on the specs here -
Part of the photographic calibration system the Curiosity has includes a 1909 penny. The first year that they were minted. The penny was given the the MSL team for free -
Their current budget is now under 0.5% of the total US budget (0.46%). Would you like to see it's budget raised to say, 1%?
If so and you are a US resident, take a moment or two to read over what these folks are pitching. Which is let NASA have penny of the Federal dollar. Yes, the budget is tight, but look at what NASA has done for us with the technology it has helped to foster over the years.
To do this, they are asking for you to sign a petition that will be sent to your Federal Representatives. You get to state what NASA and space exploration means to you, the country and the world. So let your voice be heard.

I'm surprised that nobody has mentioned the housed sized asteroid, 2011 MD, whizzing past us tonight. Closest approach to earth will be 11,000 miles -Astronomy & Space10 years ago
