Tattooine planet? Why this obsession with a planet that is considered the most boring, most backwater and criminal planet in the slice? There are definitely more interesting planets with more then one central star in fiction.

(ya I know, cause of the movies...)

NASA Extends Hubble Space Telescope Science
Operations Contract

NASA is contractually extending science operations for its Hubble Space Telescope an additional five years. The agency awarded a sole source contract extension Thursday to the Association of Universities for Research in Astronomy for continued Hubble science operations support at the Space Telescope Science Institute in Baltimore.
This action will extend the period of performance from July 1 through June 30, 2021. The contract value will increase by approximately $196.3 million for a total contract value of $2.03 billion.
This contract extension covers the work necessary to continue the science program of the Hubble mission by the Space Telescope Science Institute. The support includes the products and services required to execute science system engineering, science ground system development, science operations, science research, grants management and public outreach support for Hubble and data archive support for missions in the Mikulski Archive for Space Telescopes.

After the final space shuttle servicing mission to the telescope in 2009, Hubble is better than ever. Hubble is expected to continue to provide valuable data into the 2020s, securing its place in history as an outstanding general purpose observatory in areas ranging from our solar system to the distant universe.
In 2018, NASAs James Webb Space Telescope will be launched into space as the premier observatory of the next decade, serving astronomers worldwide to build on Hubbles legacy of discoveries and help unlock some of the biggest mysteries of the universe.

Maybe lots and lots of quiet black holes in the galaxy. hmm, maybe that is the theorised dark matter astronomers are missing?

Clandestine Black Hole May Represent New Population

Astronomers have combined data from NASAs Chandra X-ray Observatory, the Hubble Space Telescope and the National Science Foundations Karl G. Jansky Very Large Array (VLA) to conclude that a peculiar source of radio waves thought to be a distant galaxy is actually a nearby binary star system containing a low-mass star and a black hole. This identification suggests there may be a vast number of black holes in our Galaxy that have gone unnoticed until now.
For about two decades, astronomers have known about an object called VLA J213002.08+120904 (VLA J2130+12 for short). Although it is close to the line of sight to the globular cluster M15, most astronomers had thought that this source of bright radio waves was probably a distant galaxy.
Thanks to recent distance measurements with an international network of radio telescopes, including the EVN (European Very Long Baseline Interferometry Network) telescopes, the NSFs Green Bank Telescope and Arecibo Observatory, astronomers realized that VLA J2130+12 is at a distance of 7,200 light years, showing that it is well within our own Milky Way galaxy and about five times closer than M15. A deep image from Chandra reveals it can only be giving off a very small amount of X-rays, while recent VLA data indicates the source remains bright in radio waves.

This new study indicates that VLA J2130+12 is a black hole a few times the mass of our Sun that is very slowly pulling in material from a companion star. At this paltry feeding rate, VLA J2130+12 was not previously flagged as a black hole since it lacks some of the telltale signs that black holes in binaries typically display.
Usually, we find black holes when they are pulling in lots of material. Before falling into the black hole this material gets very hot and emits brightly in X-rays, said Bailey Tetarenko of the University of Alberta, Canada, who led the study. This one is so quiet that its practically a stealth black hole.
This is the first time a black hole binary system outside of a globular cluster has been initially discovered while it is in such a quiet state.
Hubble observations identified VLA J2130+12 with a star having only about one-tenth to one-fifth the mass of the Sun. The observed radio brightness and the limit on the X-ray brightness from Chandra allowed the researchers to rule out other possible interpretations, such as an ultra-cool dwarf star, a neutron star, or a white dwarf pulling material away from a companion star.
Because this study only covered a very small patch of sky, the implication is that there should be many of these quiet black holes around the Milky Way. The estimates are that tens of thousands to millions of these black holes could exist within our Galaxy, about three to thousands of times as many as previous studies have suggested.
Unless we were incredibly lucky to find one source like this in a small patch of the sky, there must be many more of these black hole binaries in our Galaxy than we used to think, said co-author Arash Bahramian, also of the University of Alberta.
There are other implications of finding that VLA J2130+12 is relatively near to us.
Some of these undiscovered black holes could be closer to the Earth than we previously thought, said Robin Arnason, a co-author from Western University, Canada However theres no need to worry as even these black holes would still be many light years away from Earth.
Sensitive radio and X-ray surveys covering large regions of the sky will need to be performed to uncover more of this missing population.
If, like many others, this black hole was formed in the plane of the Milky Way's disk, it would have needed a large kick at birth to launch it to its current position about 3,000 light years above the plane of the Galaxy.

These results appear in a paper in The Astrophysical Journal. NASA's Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program for NASA's Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, controls Chandra's science and flight operations.

Wonderful

 

Galilean moons of Jupiter(Zeus) were named after his 4 mistresses: Io, Europa, Ganymede, and Callisto by Simon Marius a contemporary of Galileo.

 

Now 400 years later spacecraft Juno is arriving https://en.wikipedia...no_(spacecraft).    In 5 July entered Jupiter orbit. 

 

Juno was Jupiter's wife...

That's not a natural aurora, it is atmospheric response to a target designator beam.

No is holy.  Some Christian images portray Jesus and Mary with bright ring of light above their head like glowing crowns.

You mean halo. All saints are portrayed this way in christian iconography.


But it really looks like Jupiter is wearing a cap.

An Earth-like Planet Might Be Orbiting Proxima Centauri
 
By Carl Engelking | August 12, 2016 11:31 pm

 

Microsoft added the “Start” button to Windows in 1995, which was the same year scientists discovered the first exoplanet orbiting a star like ours – technically, astronomers found several terrestrial planets orbiting a pulsar in 1992.

 

But in 20 years, give or take, we’ve grown spoiled by the abundance of exoplanets in the universe. Kepler, the planet-hunter, has confirmed over 2,200 of them. Today, it’s safe to assume nearly every star has its companions.

 

The ante for hyping a new exoplanet discovery is a little higher these days, but if rumors are true, this one makes the grade: astrophysicists from the European Southern Observatory (ESO) plan to announce they’ve spotted an Earth-like exoplanet orbiting the nearest star, Proxima Centauri, in its habitable zone. This, according to an anonymous source quoted in a report that appeared Friday in Der Spiegel.

 

“The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could allow it to have liquid water on its surface—an important requirement for the emergence of life,” the source said.

 

[...]

 

Big News, If It’s True

 

At just over 4 light-years from Earth, Proxima Centauri is our sun’s nearest neighbor, and it’s part of a triple-star system that includes the better known Alpha Centauri. The star’s proximity has made it an obvious target for many past exoplanet searches. All of them have come up short, which makes the most recent rumors all the more remarkable.

 

If the early reports ring true, scientists will announce this Earth-like planet near the end of August. Discover has reached out to an ESO spokesperson for comment.

 

Reason to Hold Our Breath

 

Although media reports say the rumored planet orbits in a region that’s potentially favorable for life, these smaller stars are less stable, and Proxima Centauri is known to have violent flares at times. Its occasional tantrums have made astronomers skeptical of finding life around red dwarf stars in the past.

 

However, skepticism has softened some in recent years, and SETI recently launched a major initiative to search for life around 20,000 red dwarfs, as these stars are the most common in the Milky Way galaxy.

 

Still, Proxima Centauri is only “close” on a cosmic scale. It would still take humans far too long to reach the planet with current technologies. Flying laser-sailing nanocraft to the yet-to-be-confirmed planet might be our next best bet, and that’s a pretty solid “plan b”.

There was no word on whether the putative planet might be inhabited by tailed blue humanoids.
