Pretty pictures: Bittersweet goodies from Cassini at Titan, Enceladus, and Telesto | The Planetary Society

Today, Cassini will fly by Titan, picking up a gravity assist that will tilt its orbit slightly up and out of the ring plane. That will end what has been a wonderful year of frequent encounters with Saturnian moons. In fact, this is it for Cassini equatorial orbits; the mission has no further close-up, targeted encounters with any other moon except Titan, which it must continue to pass for orbital tweaking. Cassini will continue to acquire occasional, more distant photos, but there are only three mid-sized moon flybys with any planned imaging this year, one of Mimas in March and one each of Tethys and Enceladus in November.

The scoop trench, and some interesting wind related changes in the wheel scuff over the coarse of an hour.



EDIT: Whoops, the animation should show Sol-1224.

Sol 1221 L-MastCam mosaic, selected frames only. Some interesting colour variations, some are highly likely to be compression issues, but others appear to be real variations. Raw colours, just sharpened a little.

Testovací statický zážeh recyklovaného 1.stupně F9 skoro ok (Musk hlásí kolísání tahu jednoho z motorů)
Elon Musk on Twitter: "Conducted hold-down firing of returned Falcon rocket. Data looks good overall, but engine 9 showed thrust fluctuations."

V tomto případě zřejmě půjde o nějaký nám dosud neznámý mechanismus.

KVIIIK: "Hvězdy hlavní posloupnosti spektrální třídy F3 by měly mít poměrně stabilní jasnost. Samozřejmě může docházet k drobným změnám – vlivem hvězdných skvrn, tranzitů planet apod. Schaefer ale zjistil, že od chvíle, co je hvězda pozorována, její jasnost klesá – v průměru o 0,165 ± 0,013 mag za jedno století. Ve zkoumaném období klesla jasnost o 0,193 ± 0,030 mag. To je zcela bezprecedentní jev pro daný typ hvězdy."

Tohle ještě bude zajímavý.

Found: The Most Powerful Supernova Ever Seen - Scientific American
http://www.scientificamerican.com/article/found-the-most-powerful-supernova-ever-seen/

Astronomers have glimpsed the most powerful supernova ever seen, a star in a galaxy billions of light-years away that exploded with such force it briefly shone nearly 600 billion times brighter than our Sun and 20 times brighter than all the stars in the Milky Way combined. The explosion released 10 times more energy than the Sun will radiate in 10 billion years.

If the supernova took place in our own galaxy, it would be easily seen by the naked eye even during the day; if it were 10,000 light-years away, it would appear to us at night as bright as the crescent Moon. If it were only as far away as Sirius, which at a distance of 8.6 light-years is the brightest star in the nighttime sky, it would blaze overhead almost as powerfully as the Sun. If it were as close as Pluto, it would vaporize the Earth and all the other worlds in our solar system.
