No extraterrestrial laser pulses detected from KIC 8462852, SETI reports
http://phys.org/news/2015-12-extraterrestrial-laser-pulses-kic-seti.html

The anomalous star KIC 8462852 has baffled astronomers with its erratic dimming, causing some to speculate that it's orbited by a massive structure built by an extraterrestrial civilization. To help evaluate that possibility, scientists searched for brief laser pulses from the distant star, but found none, as reported in a paper submitted to The Astrophysical Journal Letters.

News | New Clues to Ceres' Bright Spots and Origins
http://www.jpl.nasa.gov/news/news.php?feature=4785

Ceres reveals some of its well-kept secrets in two new studies in the journal Nature, thanks to data from NASA's Dawn spacecraft. They include highly anticipated insights about mysterious bright features found all over the dwarf planet's surface.

In one study, scientists identify this bright material as a kind of salt. The second study suggests the detection of ammonia-rich clays, raising questions about how Ceres formed.

"An Amateur Radio Astronomer in North Cornwall accidentally picked up the signal in 2013 and after cross checking with various lists, has identified it as LES1 built by the Massachusetts Institute of Technology and launched in 1965. The satellite failed to reach its intended orbit owing to a wiring error and has been drifting out of control ever since."

VIRGO: Zajímavý na tom je, že tahle fotka má jen o něco menší zvětšení, jako má samotnej Hubble (detektor MAMA): z Tomova pohledu měl HST velikost 0.00124°, snímač MAMA dosahuje FoVu 0.00694°, tj. Hubble by udělal selfie, kde by zabíral zhruba pětinu obrazu :)

Here is an image of the Hubble Space Telescope as it passed over Brisbane, Australia, on 4th December 2015.
It passed just under 600km overhead. The elongated shape of this 13x4 metre telescope was imaged through
a 12 Sky-Watcher Dobsonian telescope and a Canon EOS 600D with 1.4x teleconverter.

BIDAK: zítra.

Japan orbiter seeks second shot at Venus : Nature News & Comment
http://www.nature.com/news/japan-orbiter-seeks-second-shot-at-venus-1.18943
Update, 7 December (1:40 a.m. BST): Japan's Akatsuki mission has entered orbit around Venus. The spacecraft burned its engines as planned on 7 December and was captured by Venus's gravity, says team member Sanjay Limaye, a planetary scientist at the University of Wisconsin in Madison. Over the next two days, mission scientists will track the spacecraft and determine how closely the orbit matches what scientists had hoped for. That information is expected to be released at 6 p.m. Japan time (9 a.m. BST) on 9 December.
