The Fate of Merging Neutron Stars
http://aasnova.org/2017/08/09/the-fate-of-merging-neutron-stars/

When two neutron stars collide, the new object that they make can reveal information about the interior
physics of neutron stars. New theoretical work explores what we should be seeing, and what it can teach us.

So far, the only systems from which we’ve detected gravitational waves are merging black holes. But other
compact-object binaries exist and are expected to merge on observable timescales — in particular, binary
neutron stars. When two neutron stars merge, the resulting object falls into one of three categories:

- a stable neutron star,
- a black hole, or
- a supramassive neutron star, a large neutron star that’s supported by its rotation
but will eventually collapse to a black hole after it loses angular momentum.

Lunar dynamo’s lifetime extended by at least 1 billion years | MIT News
http://news.mit.edu/2017/lunar-dynamo-lifetime-extended-least-1-billion-years-0809

Findings suggest two mechanisms may have powered the moon’s ancient churning, molten core.

New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon,
generating a magnetic field that lasted at least 1 billion years longer than previously thought. Dynamos are natural generators
of magnetic fields around terrestrial bodies, and are powered by the churning of conducting fluids within many stars and planets.

In a paper published today in Science Advances, researchers from MIT and Rutgers University report that a lunar rock collected by
NASA’s Apollo 15 mission exhibits signs that it formed 1 to 2.5 billion years ago in the presence of a relatively weak magnetic
field of about 5 microtesla. That’s around 10 times weaker than Earth’s current magnetic field but still 1,000 times larger than
fields in interplanetary space today.

VIRGO: tady se to nepíše tak kategoricky, příští měsíc má padnout oficiální rozhodnutí, byť zástupci NASA připouštějí, že několikaměsíční odklad JWST neublíží :)

In this animation, we are at the centre looking out. Each dot is a galaxy that has been mapped by various surveys.
The orange region contains the galaxies the Dark Energy Survey team observed. The sparkling in the long gold regions
are supernova explosions. The empty spaces aren’t truly empty, they are just places we haven’t looked yet. Credit:

Bennu alert! OSIRIS-REx's target asteroid was recently spotted for the first time
since 2013 by the Pan-STARRS 1 telescope on Maui. The Minor Planet Center keeps records
of all published observations of Bennu.

Superbubbles in the Interstellar Medium of the Antennae Galaxies
http://www.ing.iac.es/PR/press/bubbles.html

A team of scientists led by members of the Instituto de Astrofísica de Canarias (IAC), in collaboration with the Universidad Nacional Autónoma de México (UNAM),
have detected and measured a complete "carpet" of expanding bubbles in the interstellar medium of the "Antennae", a pair of galaxies in interaction which will
eventually merge. The work, published in Monthy Notices of the Royal Astronomical Society is based on observations with GHaFaS on the William Herschel Telescope
(WHT). This instrument is capable of making a map of the velocities of a complete galaxy using the emission from the ionized hydrogen in its interstellar medium.

To detect the huge bubbles in the combined galaxy disc, the team has used BUBBLY, a method developed by some of the current authors which has already been published
in the same journal in 2015. These huge bubbles in galaxy discs are caused by the stellar winds and supernova explosions in clusters of very hot very massive stars.
They can range in size from a couple of light years to a thousand light years, depending on the number of stars in the cluster and how massive they are. The larger
ones are often called "superbubbles".

JULIANNE: Tak to jsem nečekal, zvlášť když planeta musí být celkem blízko...
Já narazil akorát na jeden starší článek, kde je řešená síla hvězdného větru a co to dělá s oběžnou drahou různě velikých objektů (ale přiznávám, že na mě už to je poněkud složité, nemám dostatečné vědomosti :))

VIRGO: To je pech :(

JULIANNE: Kdybych nebyl v práci, tak se u toho snad rozbrečím.
Už víc než rok plánuji výpravu na start, v práci jsem zařídil termín, a teď vše padlo.
Ta zpráva o kolizním start. okně se objevila už před několika měsíci, ale to ještě
vypadalo optimisticky na volbu jiného nosiče. Dnes už nahlas mluví o několikaměsíčním
zpoždění. Katastrofa. Delay se může natáhnout klidně i na půl roku.

Jediná limitace start. okna JWST je zvýšená sluneční aktivita, jinak můžou letět kdykoliv.
A je mi jasné, že chtějí mít ne 100 ale 1000% jistotu, že vše klapne. Ach jo... :-(((

VIRGO: To snad ne :(!

Magnetic Fields in Massive, Star Formation Coressu201729 | www.cfa.harvard.edu/
https://www.cfa.harvard.edu/news/su201729

Studies of molecular clouds have revealed that star formation usually occurs in a two step process. First, supersonic flows compress the clouds into dense
filaments light-years long, after which gravity collapses the densest material in the filament into cores. In this scenario, massive cores (each more than
about twenty solar–masses) preferentially form at intersections where filaments cross, producing sites of clustered star formation. The process sounds
reasonable and is expected to be efficient, but the observed rate of star formation in dense gas is only a few percent of the rate expected if the material
really were freely collapsing. To solve the problem, astronomers have proposed that magnetic fields support the cores against the collapse induced by self-gravity.

Tak tohle je peklo. :((

The much delayed and over budget next-generation +James Webb Space Telescope (JWST) (JWST) has suffered another setback prior to its journey
to the launch pad: the October 2018 launch may be in conflict with Europe’s BepiColombo mission to Mercury. Both spacecraft are to be flown
on Ariane 5 boosters, but the spaceport at Kourou, French Guiana, cannot support two flights in the same month. BepiColombo has priority due
to the tight launch window to reach Mercury. This will result in the JWST having its launch date pushed back to 2019 at the earliest.

The five sunshield layers responsible for protecting the optics and instruments of NASA’s James Webb Space Telescope are now fully installed.

Northrop Grumman Corporation in Redondo Beach, California who designed the Webb telescope’s optics and spacecraft bus for NASA’s Goddard Space
Flight Center in Greenbelt, Maryland, integrated the final flight layers into the sunshield subsystem. The team is now folding and stowing the
layers, in preparation for deployment tests in August.

The sunshield layers work together to reduce the temperatures between the hot and cold sides of the observatory by approximately 570 degrees
Fahrenheit. Each successive layer of the sunshield, made of kapton, is cooler than the one below. All layers were installed and tested in June
and July 2017 at Northrop Grumman Corporation’s Space Park facility in Redondo Beach.

“This is a huge milestone for the Webb telescope as we prepare for launch,” said Jim Flynn, Webb sunshield manager, Northrop Grumman Aerospace
Systems. “The groundbreaking tennis court sized sunshield will shield the optics from heat and assist in providing the imaging of the formation
of stars and galaxies more than 13.5 billion years ago.”
