The Most Inspirational Unofficial NASA Commercial Ever
A Youtube user thinks NASA is “the most fascinating, adventurous, epic institution ever devised by human beings”. We agree. That same guy thinks NASA has no idea how to promote itself. So he made this commercial for them. It’s beautiful.
Titled ‘The Frontier is Everywhere’, this fan-made video perfectly combines an eloquent Carl Sagan voiceover from The Pale Blue Dot with timely splicing of poignant images of Earth and outer space. In the end, going to space is as much about looking at ourselves and the current world around us as it is launching a shuttle.
NASA’s current budget cuts obviously make it a bit difficult to focus heavy resources on public relations and social media, but reconnecting the people with the wonder of space, like this video does, should be more important than it currently is.

“Una” cometa McNaught da provare a vedere in questo caldo Giugno (McNaught ne scopre a dozzine…) sembra più luminosa del previsto
Mid-June is when Comet McNaught should be most interesting, offering the best compromise between its increasing brightness and its decreasing altitude at the start of dawn. Moreover, the sky will be free of moonlight.
The helpful conjunctions continue as the comet passes about 1° north of the open cluster M34 in Perseus on the morning of June 10th, and 3° south of 1.8-magnitude Mirfak (Alpha Persei) on the 13th. It’s still about 15° high in the northeast as the sky starts to grow light on June 15th, but it appears roughly 1° lower every day after that. The comet passes zero-magnitude Capella on the 21st, and it’s very low by the 24th, when it passes 2nd-magnitude Beta Aurigae. By now Comet McNaught may be as bright as 4th or 5th magnitude, but moonlight is returning.

Marte è in opposizione! (una piccola opposizione purtroppo) Ma è bastata la prima sera serena a ricordarmelo (affilo il telescopio)
A gennaio 2010 Marte ci appare come una stella molto brillante, di uno spiccato colore rosso-arancione che la rende tra le “stelle” più brillanti di tutto il cielo invernale.
I due pianeti si trovano in prossimità del tratto di maggiore distanza dando vita ad una opposizione afelica, con una distanza Terra-Marte pari a 0,66409 Unità Astronomiche (maggiore di quella del 1997!).
Il pianeta quindi apparirà molto piccolo, con un diametro apprente simile a quello del 1997 e pari a 14,09”x14,02”.
