11:10 AM | Ou4: a huge, extended and faint bipolar outflow only ~ 700 parsecs distant
Image credit: Romano Corradi/(Instituto de Astrofísica de Canarias). Text by the incomparable Astronomy Picture of the Day (APOD) where I recommend you go for links to further web material concerning the discovery. This nebula is very faint, but also very large in planet Earth’s sky. In the mosaic image, composed with narrowband data from the […]

9:30 AM | Cosmic Duckie, You’re the One ...
(With apologies to Ernie.) Right now, in deep space 400 million kilometers from Earth, the European Space Agency probe Rosetta is easing its way toward the comet called 67P/Churyumov-Gerasimenko (which, for obvious reasons, I’ll just call ChuGer). On July 14 it was a mere 12,000 km (7400 miles) from the comet—less than the diameter of the Earth! It took a series of images of the frozen ice ball, and it’s becoming very clear that this comet is really, really weird: It’s […]

8:00 AM | Mouse Medicine to Combat Lyme
Lyme disease is a growing scourge. The Centers for Disease Control and Prevention receives about 30,000 reports of the disease each year, but agency says the number of actual diagnoses could be ten times higher. Once upon a time, we had a safe and effective vaccine to prevent the disease. But this vaccine, called Lymerix, was withdrawn in 2002, just four short […]

7:29 AM | Throwback Thursday: Remembering Neil Armstrong (Synopsis)
“Geologists have a saying: rocks remember.” -Neil Armstrong 45 years ago, the Apollo 11 mission was on its way away from planet Earth and headed towards the Moon, where the first human beings would set foot on the surface just a few days later. Back in 2012, the very first man on the Moon, Neil…

4:00 AM | Al via i nuovi esperimenti sulla materia scura
L’Ufficio di Scienza del Dipartimento di Energia (DOE) degli Stati Uniti e la National Science Foundation (NSF) hanno annunciato in questi giorni il finanziamento di tutta una serie di progetti allo scopo di cercare nuove tracce dell’enigmatica materia scura con una sensibilità molte volte superiore a quella che caratterizza gli attuali esperimenti. Denominati Generation 2 […]

4:54 PM | Rosetta’s Comet Target is a Rotating Two-body Comet
What do You Do When Your Target Looks like a Rubber Ducky in Space? Imagine designing a mission to land a probe on a comet. You have to make some assumptions about the comet nucleus, such as its shape, rotation rate, velocity, and what kind of ice it’s made of.  That’s what the planners for […]

3:52 PM | Huge Surprise for Rosetta Comet Scientists: Twins!
Europe’s Rosetta comet probe has revealed that its target, Comet 67P/Churyumov-Gerasimenko, has a Siamese twin, a thrilling discovery for scientists preparing for Rosetta’s August rendezvous... but it will also be a huge challenge. Continue reading →

2:30 PM | How the experiment that claimed to detect dark matter fooled itself (Synopsis)
Today’s article comes courtesy of Sabine Hossenfelder. Sabine is an assistant professor for high energy physics at Nordita, Stockholm. She writes a blog called Backreaction and tweets as @skdh. Dark matter is one of the most elusive and puzzling entities in our Universe today. We have plenty of indirect evidence for it, but one of…

11:30 AM | The Chaotic Glory of Starbirth
Robert Gendler is the gift that keeps on giving. He’s an accomplished astrophotographer (why, I would never make such a claim without ample evidence) who takes observations from professional observatories and adds to them images he’s taken himself and with other people. The result is substantial beauty … and here’s another bit of proof for you in the form of the ridiculously chaotic star-forming nebula NGC 1333: This cloud is a sprawling stellar nursery, a dense cloud […]

10:51 AM | How Turing accidentally invented the computer
It’s hard to do anything these days without a computer being involved in some way. From credit card readers to traffic signals to the phone in your pocket, computers can perform all kinds of tasks thanks to different software programs. So how did the programmable computer come about? In this animation, we show you how…Read more →

8:00 AM | Dog Days
These are the dog days. Hot as a dog, lazy as a dog, wanting to curl up and take naps like a dog. Please, let us lie, sleeping like them, on these summer afternoons. But the phrase didn’t originate from the habits of our earthly canine companions. Instead, it came from Sirius, the dog star. […]

Gli scienziati che lavorano all’esperimento ATLAS presso LHC, il più grande e più potente acceleratore di particelle, hanno pubblicato i risultati relativi alla prima evidenza di un processo fisico che potrà essere utilizzato per verificare il meccanismo mediante il quale la particella di Higgs conferisce massa alle particelle elementari. Si tratta di un processo molto […]

“Two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to truth; and second, the courage to follow this faint light wherever it may lead.” -Carl von Clausewitz You’ve been hanging around here long enough that you know all about dark matter’s successes,…

As NASA released a call for proposals for instruments that could fly on a future robotic mission to Jupiter’s moon Europa, some key members of Congress expressed support Tuesday for flying such a mission sooner rather than later. “This is a wonderful crowd,” said Rep. Lamar Smith (R-TX), chairman of the House Science Committee, at [...]

Three members of Congress from Alabama and Colorado have asked NASA to provide information on what they receive to be an “epidemic of anomalies” on missions performed by SpaceX. “Recent news reports have shown that an epidemic of anomalies have occurred during SpaceX launches or launch attempts,” write Reps. Mo Brooks (R-AL), Mike Coffman (R-CO), [...]

11:30 AM | Jovian Armageddon +20
Twenty years ago on this day—July 16, 1994—Jupiter got slammed, hard, by a comet. It was the first time we had ever witnessed such a collision on a planetary body other than the Earth. I’ll note I’m very glad it wasn’t Earth; we wouldn’t be here talking about it if the comet had had us in its crosshairs instead of Jupiter. The comet was discovered on March 24, 1993, by the team of Eugene and Carolyn Shoemaker and David Levy, who were taking pictures of the […]

8:40 AM | Gli alimenti bio fanno davvero bene
Spesso quando al supermercato ci si trova davanti al banco di frutta e verdura scatta il dilemma esistenziale: prendere alimenti “bio” (da agricoltura biologica) che costano di più e dovrebbero essere più salutari, oppure prendere quelli coltivati in maniera convenzionale (con uso di pesticidi e fertilizzanti), magari in offerta, dato il momento di crisi? Ma poi quelli bio sono davvero più salutari, oppure è tutta una questione di marketing? A rispondere […]

8:00 AM | Union and Reunion
Splendid, isn’t it. It’s UGC 8335 — one name, so once it was apparently mistaken for one thing though obviously it’s two. They’re spiral galaxies in the process of running into and through each other. This is a photograph by the Hubble Space Telescope; the galaxies are really there; this is real.  You could think […]

6:22 AM | A change in the perception of the impact hazard
Fig. 1 - Credit: H.A. Weaver, T.E. Smith, J.T. Trauger, R.W. Evans, NASA. On July 16th, 1994, the first fragment of the comet Shoemaker-Levy 9 impacted the dense atmosphere of Jupiter (Fig. 1). In the following week, 20 more fragments hit the planet with effects visible from the Earth. The largest chunk (named G) was 2 km in size. Its explosive fragmentation released an energy of 6 Teraton (i.e. 6 trillion of equivalent tons of TNT). It left something like a "crater" in the atmosphere with a […]
