11:29 PM | LPSC 2015: "Bloggers, please do not blog about this talk."
One presenter at the Lunar and Planetary Science Conference asked the audience not to blog about his talk because of the embargo policy of Science and Nature. I show how this results from an incorrect interpretation of those policies. TL;DR: media reports on conference presentations do not violate Science and Nature embargo policies. Let people Tweet!

Low Flyovers Will Give the Best Close-up Views Sometime in the next few months, the long-running MESSENGER mission at Mercury is going to take its last swoop over the planet, and then angle into Mercury’s surface.

“The sun is a miasma Of incandescent plasma The sun’s not simply made out of gas No, no, no The sun is a quagmire It’s not made of fire Forget what you’ve been told in the past” -They Might Be Giants It’s such a simple fact — that the Sun is made out of hydrogen…

6:30 PM | Don’t Look at the Sun
Tomorrow morning we’ll be treated to the rare sight of a near-total solar eclipse. I hope so at least; the weather forecast is looking a bit dicey at the moment. Still, I plan to be outside between 8 and 10 am to catch a glimpse of the Moon sliding across the face of the Sun. […]

5:54 PM | Ted Cruz Goes Full Orwell
In case you haven’t heard, Sen. Ted Cruz (R-Texas) is not a fan of reality. The reality of science, that is. He has a history of saying global warming–denying talking points and used some of his political power just this past week to pressure NASA into downplaying its role in measuring the effects of global warming on the planet. Earlier this week, Cruz went on Late Night With Seth Meyers, and they discussed the issue. What Cruz said, in its entirety, is what comes out of the south […]

4:00 PM | You Are Gopher Launch
After this morning’s post, we all need a Unicorn Chaser. I don’t usually post cute animal videos, but this one is pretty dang cute and is at least marginally apropos of the blog: At the Russian Baikonur Cosmodrome rocket launch site, a prairie dog made its home in the ground. Not just anywhere, though: Right in the middle of the rail tracks over which a monster transporter moves. Someone put a pretty nice webcam on the side of the hole, facing the launch site, where a Proton rocket […]

11:00 AM | Fear Mongering in the NYT: Does Wearable Tech Cause Cancer?
tl;dr: There is zero direct evidence that wearable tech causes cancer. The indirect evidence ain’t too good, either. I suppose it’s a natural human reaction to worry a bit when some new technology is announced. Will it hurt privacy rights? How will it affect the way people interact? Will it give people cancer? Of course, that last one will give you a frisson of fear, an unconscious and reflexive chill that bites the back of your brain before a more rational reaction can kick in. The […]

8:00 AM | G is for Goddamned Goshawk
I knew something was wrong the moment I opened the orchard gate. My guinea fowl were squawking like crazy, buckwheat!, buckwheat!, and none of my two dozen or so chickens were anywhere in sight. I scanned the area near around poultry barn for signs of a predator, but saw nothing. Until I reached the chicken […]

4:00 AM | ATLAS e CMS sul valore della massa di Higgs
Alla 50° conferenza “Rencontres de Moriond” di La Thuile, in Italia, i fisici degli esperimenti ATLAS e CMS hanno presentato per la prima volta i risultati congiunti sul valore della massa del bosone di Higgs. I dati indicano un valore di mH = 125.09 ± 0.24 (0.21 errore statistico ± 0.11 errore sistematico) GeV, che corrisponde ad una … Continue reading ATLAS e CMS sul valore della massa di Higgs →

Less Than 1 AU and Counting… Dear Pluto, A few days ago the New Horizons spacecraft passed an important milestone: it was 1 A.U. from its major target: Pluto. that means YOU!  That also means it was as far away from you as Earth is from the Sun. By now, it’s even closer.  A lot of us here [...]

9:43 PM | Are the first stars in the Universe invisible? (Synopsis)
“Dwell on the beauty of life. Watch the stars, and see yourself running with them.” -Marcus Aurelius Let there be light! You’d think that would be enough: that you form stars in the Universe, you see those stars in the Universe, and that tells you about what’s out there. If only it were that simple.…

6:55 PM | A Possible Detection of Dark Matter in a Dwarf Galaxy!
If dark matter particles can collide to release gamma-rays, the best place to see them will be in the centers of dwarf galaxies. Archival Fermi-LAT images around Reticulum 2 show the first ever detection of gamma-rays from a dwarf galaxy. Dark matter detection may be close at hand!
