If you had been looking up at the moon at the right moment on March 17, you could have seen an unusual flash of light ? a one-second burst of heat caused by the impact of a large meteoroid.

No telescope required.

?For about one second, the impact site was glowing like a 4th magnitude star,? NASA said in reporting the news Friday.

This meteoroid was the size of a small boulder, and was travelling very fast. NASA estimates the size at 0.3 to 0.4 meters wide, and the speed at 56,000 m.p.h.?

The resulting explosion? delivered a force equal to 5 tons of TNT.

NASA puts a footnote on the word ?explosion.? The bright light wasn?t combustion, since the moon has no oxygen atmosphere. Rather, it was the glow of molten rock and hot vapors after an impact of large kinetic force.

That said, this was the biggest such ?explosion? in eight years of close monitoring of the moon?s surface.

And it?s not that meteoroids on the lunar surface are rare.

The moon lacks a protective atmosphere like Earth?s, in which meteoroids typically burn up. Lunar meteor showers have turned out to be more common than expected, with hundreds of detectable impacts per year.

On March 17, the pyrotechnics on the moon coincided with an active night for meteors in Earth?s atmosphere as well.

NASA?s Space Exploration Policy eventually calls for extended astronaut stays on the moon, so tracking meteor activity has long-term relevance.

?Identifying the sources of lunar meteors and measuring their impact rates gives future lunar explorers an idea of what to expect,? the space agency said in announcing the bright explosion Friday. ?Is it safe to go on a moonwalk, or not?? The middle of March might be a good time to stay inside.??

How To Find A Reliable Real Estate Law Firm ? Hot Article Depot

Nobody would want to hire an incompetent worcester real estate law firm. An incompetent legal service will not be able to turn the case in your favor. That is why the most important element in the lawyer?s credentials is his experience.

The lawyer knows what to do with the case. He is knowledgeable enough about the workarounds when there are problems encounter in procuring certain legal documents for the proceedings. Know that law firms are composed of many lawyers.

Compare how many of those cases handled are successful. It does not also add up that the lawyer has handled several cases but only a handful of them were successful. You do not want that ratio in the lawyer?s credentials. The competence of the lawyer is also important in this matter. The competence of the lawyer is measured by the number of successful cases he has handled over the years.

Get his credentials and go over the experiences he has had over the years. The experiences that you will see on his credentials should show you past litigation cases that have something to do land disputes and other related cases to land and other real properties. Talk to the lawyer. It is important that you finalize your decision of hiring him, you are able to talk with him before hand.

It is possible that they have heard of the name. Or, someone from their social circle has dealt with the lawyer before. Ask to be connected with that person.

For an attorney to be registered, he needs to comply the requirements need for the registration of that state. He may have to pass another bar examination in that state to be given a license to practice in that state. Why this is so is because the laws governing cases like this are not the same in all states.

Otherwise, he would convince you not to get this lawyer or be wary of certain things about him. Ask how much he paid for this service before. Know that your case and his case might not be the same altogether as far as the depth of work the lawyer needs to do.

Meaning, he has the authority to share his opinion about the qualities of the lawyer and the quality of work that he did. You will also know at this point if the past client is satisfied with the service or not. The major denominator of the satisfaction of the client is the success of the case.

But just so that you have a basis for a similar type of case, it is good that you know how much he paid before. Ask the lawyer of the rundown of the cost of the case. This is just an estimate of the possible cost you will be paying for the service. The worcester real estate law firm can give you a ballpark figure but the estimate can change because the details of the work are clearly dependent on circumstances that are yet to happen.

Dell announces Q1 2014 results: $14 billion revenue, 21 cents EPS

We doubt recent earnings reports at Dell have been met with balloons on the quad and sheet cake in the cafe. And that's likely the case this time around as well. The PC maker reported revenue of $14.07 billion, but earnings of just $372 million or 21 cents per share -- a bit shy of estimates. The company's stock price is hovering around the $13.65 mark, the amount shareholders have been promised once the firm goes private later this year. As you might imagine, Dell's books won't be open to public scrutiny once that transaction closes, making this one of the very last earnings reports. Things may not be looking so good for Q1 2014, but will the company end its public streak on a high note? We'll find out soon enough.

HiRISE Mars camera reveals hundreds of impacts each year

Friday, May 17, 2013

Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across.

Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade, using images from the spacecraft to determine when the craters appeared. The 200-per-year planetwide estimate is a calculation based on the number found in a systematic survey of a portion of the planet.

The University of Arizona's High Resolution Imaging Science Experiment, or HiRISE camera, took pictures of the fresh craters at sites where before and after images had been taken. This combination provided a new way to make direct measurements of the impact rate on Mars and will lead to better age estimates of recent features on Mars, some of which may have been the result of climate change.

"It's exciting to find these new craters right after they form," said Ingrid Daubar of the UA, lead author of the paper published online this month by the journal Icarus. "It reminds you Mars is an active planet, and we can study processes that are happening today."

These asteroids or comet fragments typically are no more than 3 to 6 feet (1 to 2 meters) in diameter. Space rocks too small to reach the ground on Earth cause craters on Mars because the Red Planet has a much thinner atmosphere.

HiRISE targeted places where dark spots had appeared during the time between images taken by the spacecraft's Context Camera, or CTX, or cameras on other orbiters. The new estimate of cratering rate is based on a portion of the 248 new craters detected. If comes from a systematic check of a dusty fraction of the planet with CTX since late 2006.

The impacts disturb the dust, creating noticeable blast zones. In this part of the research, 44 fresh impact sites were identified.

The meteor over Chelyabinsk, Russia, in February was about 10 times bigger than the objects that dug the fresh Martian craters.

Estimates of the rate at which new craters appear serve as scientists' best yardstick for estimating the ages of exposed landscape surfaces on Mars and other worlds.

Daubar and co-authors calculated a rate for how frequently new craters at least 12.8 feet (3.9 meters) in diameter are excavated. The rate is equivalent to an average of one each year on each area of the Martian surface roughly the size of the U.S. state of Texas. Earlier estimates pegged the cratering rate at three to 10 times more craters per year. They were based on studies of craters on the moon and the ages of lunar rocks collected during NASA's Apollo missions in the late 1960s and early 1970s.

"Mars now has the best-known current rate of cratering in the solar system," said UA's HiRISE Principal Investigator Alfred McEwen, a co-author on the paper.

MRO has been examining Mars with six instruments since 2006. Daubar is an imaging targeting specialist who has been on the HiRISE uplink operation s team from the very beginning. She is also a graduate student in the UA's department of planetary science and plans on graduating with her doctorate in spring 2014.

"There are five of us who help plan the images that HiRISE will take over a two-week cycle," she explained. "We work with science team members across the world to understand their science goals, help select the image targets and compile the commands for the spacecraft and the camera."

"The longevity of this mission is providing wonderful opportunities for investigating changes on Mars," said MRO Deputy Project Scientist Leslie Tamppari of NASA's Jet Propulsion Laboratory in Pasadena, Calif.

Hearing on IRS: What ousted chief offers, Republicans don't buy

Was the Internal Revenue Service criminal in layering on extra scrutiny to tea party groups seeking nonprofit status, or just bureaucratically shortsighted and ?obnoxious,? as the agency?s former head put it Friday?

The first position was taken by Republican members of the House Ways and Means Committee, which grilled Steven Miller, the IRS?s former acting head, during Friday?s committee hearing on the IRS scandal ? the first such panel since the subject came to light a week ago.

The latter position was the counterclaim by Mr. Miller, the man who recently tendered his resignation at President Obama?s request even though he took over the agency last November, after the targeting had stopped.

?I think that what happened here was that foolish mistakes were made by people trying to be more efficient in their workload selection,? said Miller, who offered he found out about the issue in May of last year, when he was deputy commissioner for services and enforcement.

Miller?s explanation for why the IRS targeted conservative groups that applied for tax-exempt status and unduly delayed those applications tracked with what the Treasury Department?s inspector general for tax administration found in a report issued earlier this week.

?The listing described in the report, while intolerable, was a mistake and not an act of partisanship,? Miller said.

Agency employees thought they had found a useful heuristic for sorting a great number of groups that potentially required more research ? flagging the names of organizations containing the words ?tea party? or ?9/12,? for example. Such research can determine if the group applying for tax exemption spent more of its time and money on politics than allowed by the 501(c)(4) designation being sought.

IRS staffers had no outside political interference, the report found.

On Friday Miller, echoing points made by Democrats on the panel, asked the committee to help sharpen the relevant tax law to make it easier to enforce ? and beef up the agency?s budget.

?With respect to political activity, it would be a wonderful thing to get better rules, to get more clear rules,? he said. ?In terms of our ability to get to this work, it would be good to get a little budget to get more than the people we have to do 70,000 applications and do our job.?

The panel?s Republicans simply weren?t buying what Miller was saying.

?On the one hand, you're arguing today that the IRS is not corrupt, but the subtext of that is you're saying, ?Look, we're just incompetent,? ? said Rep. Peter Roskam (R) of Illinois. ?It is a perilous pathway to go down.?

House Republicans see the tendrils of malfeasance reaching into the White House, and many GOP members of the committee attempted to present the IRS scandal as evidence of an agency running amok.

?We also know that these revelations are just the tip of the iceberg,? said Rep. Dave Camp (R) of Michigan, the committee?s chairman. ?It would be a mistake to treat this as just one scandal.?

In addition to the discussion of extra scrutiny of applications, Representative Camp offered up the fact that a White House official shared details of a private company?s tax status with reporters in August 2010 and that in May of the following year, the IRS asked donors to 501(c)(4) groups about whether they were paying appropriate gift taxes. Camp also said that the IRS leaked details of the donor list of a conservative organization and tax applications from other conservative groups to media organizations in 2012.

To Camp?s list of complaints, conservatives would add one more: the fact that a woman who helped oversee the IRS?s tax-exempt division was transferred to head IRS-related implementation of the president?s health-care law.

Senate minority leader Mitch McConnell (R) of Kentucky, a lawmaker who has frequently criticized the Obama administration for what he sees as the abuse of its power against conservative groups, called that revelation ?stunning ? just stunning.?

Asked Rep. Pat Tiberi (R) of Ohio: ?Why would you promote somebody to that position who was in charge of the exempt organization division, which certainly has had some controversy over the last couple years, under an investigation??

?Because she's a superb civil servant, sir,? Miller responded.

While neither Miller nor Republican members of the committee offered a clear timeline of when the woman, Sarah Hall Ingram, switched roles, Miller added that he ?wouldn?t imagine? she was involved in the tea party issue.

Overall, Republicans were furious that the IRS testimony before their committee appeared to steer away from the ongoing investigation into the extra IRS scrutiny that some of their constituents reported.

Miller argued that he had always been truthful to the committee and that at previous hearings, he and other senior staffers did not have all the facts the committee wanted because the investigation by the inspector general was still pending.

Two facts stood out as emblematic of the larger discussion over dates and times.

At the time of the inspector general?s audit, some 300 applications for 501(c)(4) status were being held out for special attention by the IRS. Miller pointed out that only about 70 of those cases were for conservative groups.

At another juncture in the hearing, J. Russell George, the Treasury inspector general who conducted the report, responded to questions from Rep. Adrian Smith (R) of Nebraska about the IRS requesting donor lists from various applicants. He offered that of the 27 organizations that received requests for a donor list, about half (13) were tea party groups.

In Miller?s mind, these facts show that the IRS was not simply nailing conservative groups to the exclusion of all others.

But the inspector general found that all the groups with ?tea party? or similar names were forwarded for special screening.

And while groups of other political persuasions got extra screening, ?there were no ?progressive? or ?organizing? buzzwords that were used for targeting, is that correct?? asked Rep. Paul Ryan (R) of Wisconsin.

?That?s correct,? Miller said.

Soundhalo beta for Android lets fans buy concert videos before the show is over

The urge to record video at a concert can be distracting for fans and musicians alike -- enough so that some bands now forbid it altogether. Soundhalo's new media service and Android beta might just keep both sides happy, as long as they've got the money to spend. The platform lets a backstage team make audio and video available for purchase from the app, as soon as a song is done; theoretically, you can start a replay before you've left the front row. Downloadable copies are DRM-free, and concert-goers can always grab tracks again from the app or the web. Soundhalo is still working on an iOS release, but Android users who've been to Alt-J's recent Brixton shows (or just missed out) can already relive the memories at about $1.50 a pop.
