“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”.

Ever wonder what a failed launch looks like? Check this out. (Note that there is a video of the event at that site.) Launch failures come in many flavors, from huge explosions to a simple failure to reach orbit (i.e. “crash”). At this point no nation is laying claim to this one, and experts are speculating about possible new atmospheric phenomena, etc. But to me, this looks like a launch gone bad, with the root cause occurring right at launch.

Aurora settembrina in canada

Aurora Over Yellowknife

Explanation: Sometimes, after your eyes adapt to the dark, a spectacular sky appears. In this case, a picturesque lake lies in front of you, beautiful green auroras flap high above you, brilliant stars shine far in the distance, and a brilliant moon shines just ahead of you. This digitally fused panorama was captured earlier this month from Yellowknife, Northwest Territories, Canada, and includes the Pleiades open cluster of stars just to the upper right of the Moon. Since aurora are ultimately started by solar activity, this current flurry of aurora is somewhat surprising, given the historic lack of sunspots and other activity on the Sun over the past two years. This time of year is known as aurora season, however, for noted average increases in auroras. The reason for the yearly increase is not known for sure, but possibly relates to the tilt of the Earth creating a more easily traversable connection between the Earth’s magnetic field and the magnetic field of the Sun’s changing wind streams.
