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.

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.

This processed image is the highest-resolution color look yet at the haze layers in Pluto’s atmosphere. Shown in approximate true color,
the picture was constructed from a mosaic of four panchromatic images from the Long Range Reconnaissance Imager (LORRI) splashed with
Ralph/Multispectral Visible Imaging Camera (MVIC) four-color filter data, all acquired by NASA’s New Horizons spacecraft on July 14, 2015.
The resolution is 1 kilometer (0.6 miles) per pixel; the sun illuminates the scene from the right.

KAERO:

Včera ve 20 h našeho času pokořila sonda Juno rekord nejvzdálenějšího umělého tělesa od Slunce napájeného slunečními panely.
V té době byl od Slunce 793 Mkm. Rekord do té doby držela Rosetta se vzdáleností 792 Mkm v říjnu 2012.

Space Images | Enceladus Dalmatian Terrain Close-up
http://www.jpl.nasa.gov/spaceimages/details.php?id=pia20017

During its final close flyby of Saturn's moon Enceladus, NASA's Cassini spacecraft revisited a landscape, and a mystery, that it had originally glimpsed more than 10 years earlier.

In views of this terrain captured during a 2005 flyby (see PIA06188), imaging scientists noticed small dark spots of an uncertain nature. Observing the same features in this false-color view, at higher resolution than before, provides some new insights. The spots are evidently large, relatively dark protrusions of solid "bedrock" ice and ice blocks scattered on and around the prominent ridge that runs across the scene from north to south (from top center toward lower left). The ice blocks range in size from dozens to hundreds of feet (tens to hundreds of meters).
