9:43 AM | Scoperto uno dei più antichi amuleti cristiani
Grazie all’uso di tecniche di indagine scientifica integrate con metodi tipici degli studi umanistici è stata scoperta una delle più antiche testimonianze del primo cristianesimo: un papiro risalente a circa 1.400 anni fa, che contiene riferimenti all’Ultima Cena e altri passi del Vecchio e del Nuovo Testamento. Il documento, conservato nella John Rylands Library dell'Università di Manchester,non è mai studiato prima, e potrebbe essere stato utilizzato in […]

8:53 AM | Relativistic jets from low-mass active galactic nuclei
Today, I would like to write about a research I have conducted during the latest years. A couple of years ago, in one of my earlier posts, I have summarized the meaning of the discovery of powerful relativistic jets in Narrow-Line Seyfert 1 Galaxies. ☞ A recent more detailed review can be found here. The main point is that it allowed us to understand that relativistic jets in active galactic nuclei (AGN) do not depend on the mass of the central black hole, as it was supposed […]

6:00 AM | L’Astronomia alle frontiere della Scienza
L’astronomia è, per sua natura, una materia di studio interdisciplinare perchè coinvolge la matematica, la fisica, la chimica e la biologia. Gli astronomi utilizzano, e spesso sviluppano, la tecnologia più recente, i computer più veloci e i programmi più sofisticati. Nel libro che mi piace suggerire oggi, Astronomy at the Frontiers of Science, edito da Springer, […]

9:18 PM | Some early galaxies were oddly heavy and starry
From detailed modeling and what we see of modern galaxies, we expect the earliest galaxies to be small and have intense star formation. A new survey using data from the Spitzer space telescope and the Subaru telescope in Hawaii has found a lot of surprisingly massive galaxies at the edge of our ability to observe, […]

12:00 PM | Volcanado
Hot on the heels of the incredible volcanic explosion video I posted recently comes another in the “holy cow these things really exist?!” department: a volcano tornado. Yes, you read that right. OK, technically, it’s a vortex, more like a dust devil than a tornado. Still. Nicarnica Aviation is a company that has created infrared cameras that can detect volcanic ash in the air as a safety measure for pilots; ash is composed of microscopic particles of rock that are very jagged, […]

9:00 AM | Magnetism and Variability in O stars
For more than 30 years, spectroscopic observations from space have shown that wind variability in massive OB stars is a widespread phenomenon. This variability is not strictly periodic, but cyclic (like sunspots) with a dominant quasi period that scales with the estimated rotation period. The underlying cause or trigger of this variability is not known. […]

6:00 AM | IAU Symposium 313: “Extragalactic jets from every angle”
Jets appear in a wide range of astrophysical sources. In extragalactic systems, they signal accretion onto a supermassive black hole, providing unique testbeds in which to probe an array of fundamental physics processes. Over the past decade, major advances have been made in understanding jets due to the advent of an unprecedented number of space- […]

1:01 PM | La coltivazione del pesco ha 8 mila anni
La prima pesca coltivata fu assaggiata in Cina, precisamente nella provincia dello Zhejiang, e prima di 7.500 anni fa. Questa è infatti la datazione più antica, ad oggi, stimata per la domesticazione dell'albero di pesco, come riporta uno studio su PLoS One.  Domesticare una pianta significa individuare una specie selvatica interessante e iniziare a coltivarla, selezionando le caratteristiche che la rendono più adatta alle esigenze dell'essere umano. In questo modo, […]

12:00 PM | Breakaway +15
As I do every year on this day: Wear flared off-white polyester pants, go outside, face where the Moon used to be before it blasted out of Earth orbit, and pour out a drop of wine on the ground for the 311 lost souls of Moonbase Alpha. I can’t believe it’s been 15 years now. I miss seeing Eagles soaring in the sky above.

8:36 PM | Will the Higgs Boson Destroy the Universe?
Improbable as it may seem, this question has been pinging around the Internet a lot this past week, because of a mix of Stephen Hawking and shameless sensationalism. Life is short (with or without the help of the Higgs), so I’ll answer it as succinctly as I can. No. If you want to get technical, […]The post Will the Higgs Boson Destroy the Universe? appeared first on Out There.
