Hubble takes an image of Comet Siding Spring and finds two jets coming off the nucleus.
The comet will fly past Mars on October 19 by a distance of only 84,000 miles, which makes understanding its jets crucially important for protecting the various spacecraft that orbit the red planet.
A different look at 25 famous places that gives you a better idea of what it is really like to visit them.
I thought the images of the Mona Lisa and the Alamo were the most revealing.
Government power relies on violence and coercion, regardless of where and when.
The author justly lambasts both the left and the right for playing favorites when it comes to the abuse of power by our federal government.
Feel the love: A feminist comedian calls for violence against conservative Christians.
I really like how effective Obama’s call for civility after the Tucson shootings has been. Considering how rarely he has spoken up on the subject since then, however, you’d almost think his demand that people be civil really only applied to conservatives, while liberals were to remain free to be as abusive and hateful as they like.
Rosetta has taken its first picture of its target comet since coming out of hibernation.
The comet, 67P/Churyumov–Gerasimenko, is only a dot now, but will look far more interesting when Rosetta goes into orbit around it in August.
A fire at a radar site used by the Air Force to track rockets lifting off at the Kennedy Space Center has delayed all launches there, including SpaceX’s next Falcon 9 flight.
Initially the Air Force thought they could make repairs relatively quick, but now think it could take as long as 45 days. No new launch date for the Falcon 9/Dragon flight as yet been set.
Hurrah! A college student who was attacked and then arrested by Virginia Department of Alcoholic Beverage Control agents because she and two friends had purchased a case of sparkling water is now suing Virginia and those seven agents for $40 million.
The key here is that she is not only suing the state, she is suing the agents themselves. They screwed up, but instead of apologizing to her immediately they arrested her and put her in jail for the night in order to intimidate her. I am glad she is not intimidated.
Though engineers still don’t know why a Soyuz spacecraft carrying three astronauts to ISS was oriented incorrectly — thereby preventing a scheduled engine firing yesterday — they have uploaded new software and have subsequently executed two additional burns successfully.
The engine firings are excellent news, since they demonstrate that the capsule can make the necessary orbital maneuvers to get it to ISS.
Astronomers have found an asteroid with its own rings.
Chariklo is the largest member of a class known as the Centaurs and it orbits between Saturn and Uranus in the outer Solar System. Predictions had shown that it would pass in front of the star UCAC4 248-108672 on 3 June 2013, as seen from South America. Astronomers using telescopes at seven different locations, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile, were able to watch the star apparently vanish for a few seconds as its light was blocked by Chariklo — an occultation.
But they found much more than they were expecting. A few seconds before, and again a few seconds after the main occultation there were two further very short dips in the star’s apparent brightness. Something around Chariklo was blocking the light! By comparing what was seen from different sites the team could reconstruct not only the shape and size of the object itself but also the shape, width, orientation and other properties of the newly discovered rings.
The team found that the ring system consists of two sharply confined rings only seven and three kilometres wide, separated by a clear gap of nine kilometres — around a small 250-kilometre diameter object orbiting beyond Saturn.
Back on December 31, 2013, I put up a post about a New York Times article in which it was reported that Americorps volunteers were losing their health insurance plans because of Obamacare, much to their chagrin.
In reading the article, the quote that stood out to me was this one from one volunteer named Sarah Sklaw.
Sarah L. Sklaw, a 22-year-old Vista member from New York City, said: “I really support the Affordable Care Act, and I don’t want to be a naysayer. But it was surprising and frustrating to be told that our health coverage would not meet the law’s standards, especially because the Corporation for National and Community Service told us at orientation in August that we did not need to worry about the issue.”
My reaction? “In other words, she supported Obamacare, partly because she was told “if she liked her health plan, she could keep her health plan. Period.” She has now discovered that this was a lie and is angry. Who wudda thunk it?”
Last week Sarah Sklaw emailed me. She was very unhappy about my post because in her mind I misrepresented her feelings about the situation. This is her email:

Astronomers have discovered a new dwarf planet about 300 miles wide at the outer edge of the solar system.
The closest it gets to the Sun is 80 AU, or about 7.4 billion miles. More tantalizing, however,
… the findings also suggest the presence of another large planet in the outer reaches of the solar system. When the authors plotted the motion of Sedna, 2012 VP113, and distant Kuiper belt objects, they noticed some odd behaviors which they couldn’t explain — but which a massive, “super-Earth” planet about 250 AU away could. They note that such a dimly lit planet “would be fainter than current all-sky survey detection limits, as would larger and more distant perturbers” (i.e., planets), so it’s certainly possible… but right now it’s little more than a guess. A weird, intriguing guess.
Police state: A Kansas family’s home is raided by a gun-toting SWAT team because police found tea leaves in their garbage pails.
The family, which were entirely innocent of any wrong-doing, also had to spend $25,000 to find out this fact, as the police stonewalled them when they asked why their house was raided.
