9:05 PM | Milky Way View From Japanese Observatory
Taken on Sept. 16th 2014, found it today via NAOJ"This panorama combines 7 pictures taken with a diagonal fisheye lens.The conditions inside Mizusawa VLBI Observatory are good and it is possible to see the Milky Way, but if you travel 30 minutes by car to the city outskirts, the city lights decrease and it is even easier to see.Objects like the Great Summer Triangle and the Andromeda Galaxy are pictured around the rainbow shaped Milky Way."Image Credit: National Astronomical […]

7:22 PM | Weekend Diversion: Norway vs. Kenya (Synopsis)
“I didn’t know any successful actors in Kenya, so I felt like I could get away with going to college to study film more easily than I could with saying, ‘I want to be an actor.’ That’s what I did.” -Lupita Nyong’o There’s nothing that gets me excited quite like… completely fabricated, unnecessary bickering on…

5:03 PM | Comments of the Week #35: A 2-week spectacular!
“It’s a tad easier to be proud when you come in first than it is when you finish further back. But there’s no reason to hide when you don’t do as well as you’d hoped. You can’t run away from your problems.” -My Little Pony It’s been two weeks since our last edition of Comments of…

2:46 PM | Epic 4K Sun Video, with Bonus Sunspot Tantrums
Not long ago, the ridiculously huge sunspot called Active Region 2192 ruled the face of the Sun. Bigger than Jupiter, it was easily seen by the (adequately protected) naked eye, and it was a distracting though extremely cool blemish during October’s solar eclipse. A sunspot that big has a lot of storage space to stuff magnetic fields, and 2192 didn’t disappoint. Sunspots are essentially magnetic phenomena, and as the huge looping magnetic field lines in the spot tangled up, they […]

11:27 AM | E-cig, efficaci per smettere di fumare
“Un fumatore su due può abbandonare l’uso della sigaretta tradizionale con una significativa riduzione del danno respiratorio grazie a un uso guidato della sigaretta elettronica”. È la conclusione a cui sono giunti i ricercatori dell’Osservatorio Fumo, Alcol e Droga dell’Istituto Superiore di Sanità, che in collaborazione con il Centro Antifumo dell’Ospedale San Giovanni Bosco Asl To 2 di Torino hanno monitorato l’uso […]

11:27 AM | Come vanno in guerra le formiche?
Da sempre simbolo di operosità, le formiche in realtà sono anche agguerriti soldati, pronti a scatenare violente battaglie per difendere le loro risorse, sia all'aperto che dentro i formicai. Un nuovo studio dell'Università di Firenze, pubblicato sulla rivista Plos One, ha analizzato oggi le strategie con cui le formiche combattono le loro battaglie, svelando i meccanismi con cui questi insetti mettono in atto gli attacchi, e realizzando un modello che permette di prevedere […]

5:42 PM | Magnetars! Explosions Occuring On Neutron Stars Due To Magnetic And Seismic Violence
Magnetars are neutron stars that have EXTREME magnetic activity, as well as intense seismic rippling.  These two attributes cause explosions on the surface of them, which is quite awe inspiring. Below is a new (late oct.) artist rendition of a magnetar, straight out of NASA's Goddard Studio.Image credit: NASA's Goddard Space Flight Center/S.

12:30 PM | Hey, Galileo Was Right!
One of the funny things about being a human is that our intuition can steer us wrong, even on things that should be pretty obvious, things we see literally every day. For example, if you ask someone what would fall faster, a bowling ball or a marble, I bet a lot of folks would say the heavier bowling ball falls faster. But in fact, if dropped from a meter or so off the ground, they’d fall at the same rate. Gravity accelerates them at the same rate, so they fall at the same rate. Part of […]

9:00 AM | The Last Word: November 10-14, 2014
More imaging, more problems: Colin Norman’s medical troubles began with his heart. But in this week’s post, an MRI of Colin’s heart shows that his pancreas is wearing a cyst ominously called an intraductal papillary mucinous neoplasm. These cysts may be an early sign of pancreatic cancer, but using them to screen for the disease . . . well, that’s tricky. […]

Por Elvis Cantelli, aluno de Divulgação em Astronomia no IAG/USPAo lermos uma matéria sobre ciência, em geral não temos uma idéia sobre o pesquisador e como ele se encaixa no meio académico. Porém, entre seus pares, o cientista está sendo analisado e classificado constantemente, para fins de financiamento ou afim de que sua instituição seja avaliada, ou para o conceito de seus cursos de pós­ […]

11:00 PM | At What Age Can You Be Granted A Patent?
Actually, there are no age limits. The oldest person I can find that was granted a patent in the U.S. was USC Professor Simon Ramo, who received his patent at age 100.  I’m not sure I could invent something patentable now, let alone at 100. A minor(s) may need an adult to help with the … Continue reading →

10:06 PM | Rosetta Spots Site of Philae’s First Bounce
Update (Nov. 14, 2014 at 23:00 UTC): Contact with Philae has been re-established! Data taken from the surface (including drill samples) have been sent back to Earth. Not only that, a command was sent to rotate the lander, and that worked as well! It rotated by 35°, enough to point a bigger solar panel up to the Sun. Reports indicate power is flowing, so the life of the mission has at the very least been extended somewhat. This is incredible work by the ESA team! Update 2 (Nov. 15, 2014 at […]

5:38 PM | Quick Philae Update
There’s more news this morning about Philae, the European Space Agency lander that is on the surface of the comet 67P/Churyumov-Gerasimenko. Recap: It set down on the comet yesterday, but the harpoons didn’t deploy. It bounced, twice, and came to rest a kilometer or so from the desired landing site. It’s not known precisely where it is, and it’s too small for the Rosetta spacecraft, still orbiting the comet, to easily find it. Update, Nov. 14, 2014 at 18:00 UTC: The ESA […]
