5:50 PM | Supernova Cleans Up its Surroundings
Supernovas are the spectacular ends to the lives of many massive stars. These explosions, which occur on average twice a century in the Milky Way, can produce enormous amounts of energy and be as bright as an entire galaxy. These events are also important because the remains of the shattered star are hurled into space. As this debris field - called a supernova remnant - expands, it carries the material it encounters along with it. Astronomers have identified a supernova remnant that has […]

4:00 PM | The BOSS Does A Speed Check.
The Baryon Oscillation Spectroscopic Survey (BOSS) has just completed the most accurate speed check of the early Universe. The measurements show that the early Universe was expanding about 1% every 44 million years.  Although that doesn’t seem like much, I can tell you from my own, personal, expansion of 1% over the last 10 years … Continue reading →

3:51 PM | Bambi Versus the Space Alien
BA Tweep owlice sent me a link to a video that had me chuckling. It’s from the local Oklahoma City Fox station, KOKH, showing a Mississippi couple talking about some footage from a camera they set up outside their house. They were hoping to get a deer or two, but what they got was (cue creepy music) a UFO. Well, kinda. Watch: So what is it? Happily, the timeline is dramatically read by the newscaster: At 7:29 a dim light appears, at 7:35 it gets brighter, at 7:53 a weird shape appears, […]

2:15 PM | Cosa rischiamo se la Russia ci taglia il gas?
Cosa succederebbe in Europa se uno dei principali fornitori di gas chiudesse all'improvviso il rubinetto? Lo scenario non è poi tanto fantascientifico, in questi tempi turbolenti. Ricordiamo l'attacco al gasdotto algerino di un anno fa ma anche e soprattutto la attuale crisi tra la Russia, da dove proviene un terzo del gas consumato dagli europei (italiani compresi) e l'Ucraina, vero e proprio crocevia dei diversi gasdotti che trasportano il gas russo verso Ovest. Proprio per […]

1:39 PM | Come funziona la fecondazione assistita
Era un processo di smantellamento che andava avanti ormai da anni. E ieri è stata sferrata la picconata più grossa: la Corte Costituzionale ha stabilito una volta per tutte che il divieto di fecondazione eterologa è incostituzionale. Le coppie non fertili che vogliono avere un figlio, da oggi, non saranno più costrette ad andare all’estero (uno dei tanti escamotage che rendevano il divieto aggirabile), ma potranno ricorrere alla donazione di ovociti e […]

11:57 AM | 5 modi per far mangiare frutta e verdura ai bambini
Sono colorate, contengono tante fibre, minerali e vitamine, e proteggono da tumori e malattie cardiovascolari, ma frutta e verdura si sa non sono sempre il cibo preferito da grandi e piccini. Soprattutto per i più piccoli infatti, che dovendo scegliere preferiscono alimenti dolci e saporiti. Ma convincere anche i bambini a mangiare più mele, carote, spinaci o qualsiasi altro prodotto dell'orto vogliate si può. Gli ultimi consigli in merito sono stati elaborati a partire dal […]

11:45 AM | Mars at Its Best Right Now
Due to the orbital dance of the planets, Mars is currently at its best showing of the year, as close to Earth as it gets, and shining brightly all night long. To see it, go outside. If it’s after sunset and the sky is dark, face southeast. Look up. There it is. It’s one of the brightest objects in the sky, and shines with an orangey glow. The technical term for Mars’s place in the sky right now is opposition, because it is opposite (literally, 180° around the sky) from the […]

9:53 AM | Chance Meeting Creates Celestial Diamond Ring
Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 — usually known as Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star, and bears an uncanny resemblance to a diamond…Read more →

8:00 AM | Waiting for Peak Bloom
It was a long winter in North America.  The kind of winter where you think, well, that must have been the last snow storm, and then it snows three more times. It seemed like this might be the year when, Narnia-style, winter never ends. Here in Washington, we gauge spring by the cherry trees. The […]

5:32 AM | Particle Fever, il documentario sull'Lhc
È una macchina enorme il Large Hadron Collider (Lhc), l’acceleratore di particelle del Cern in Svizzera. È la più grande macchina mai costruita, un anello di 27 chilometri di magneti superconduttori che permettono a minuscole particelle di scontrarsi a velocità incredibili e così produrre altre particelle. Serve a verificare le teorie fondamentali della fisica, a capire meglio le fondamenta dell’Universo, a spiegare la realtà che vediamo e […]

5:32 AM | Libertà di ricerca: l'Italia è ultima in Europa
Qui nel “bel paese” della ricerca scientifica sembra interessarci ben poco. A dimostrarlo è uno studio coordinato da Andrea Boggio, della Bryant University, e presentato durante la Terza sessione del Congresso Mondiale per la Libertà di Ricerca Scientifica, organizzato a Roma dal quattro al sei aprile scorsi dall’Associazione Luca Coscioni, con il titolo “Colmare il divario tra scienza e politica”. Quella che emerge è una vera e propria mappa, […]

“And everything under the sun is in tune But the sun is eclipsed by the moon.” -Pink Floyd We normally think of eclipses as rare phenomena, something that happens only occasionally. While it’s true than any particular location only experiences eclipses — particularly solar eclipses — infrequently, we actually experience these things around four times a…

4:55 PM | Farewell, But Not Really
Big news here at Always A Scientist! I have thoroughly enjoyed creating and writing for this blog and have endless appreciation for those of you that have followed along and commented. However, I have found it hard to keep up with writing posts and staying motivated. Perhaps many other bloggers have felt similarly. Rachel (of Rachel's Rambling fame) certainly did about her own personal blog, The Practical Ecologist, and approached me with a rather delightful proposal: combine forces and launch […]

4:00 PM | Yet Another Zero G Day Ruse.
Please stop, stop, please…help me out people…stop the madness. According to ‘experts’ on the Internet, the alignment of some of the planets, the Moon, Mars, and Pluto is going to cause gravity to cease on Earth for a few seconds. Say it isn’t so. Ok. It isn’t so.  Let’s just take a look at the … Continue reading →
