A Tour of Star RW Aur A | NASA Chandra
July 18, 2018: Since 1937, astronomers have puzzled over the curious variability of a young star named RW Aur A, which is located about 450 light years from Earth. Every few decades, the star's optical light has faded briefly before brightening again. In recent years, astronomers have observed the star dimming more frequently, and for longer periods.
Using NASA's Chandra X-ray Observatory, a team of scientists may have uncovered what caused the star's most recent dimming event: a collision of two infant planetary bodies. Once the planets were destroyed, the debris would have fallen onto the star, generating a thick veil of dust and gas. This would have temporarily obscured the star's light, explaining the dimming astronomers have seen.
Computer simulations have long predicted that planets can fall into a young star, but scientists have never before observed that before now. If this most recent study is correct, it would be the first time that astronomers have directly observed a young star devouring a planet.
Because the X-rays come from the hot outer atmosphere of the star, changes in the X-ray spectrum—the intensity of X-rays measured at different wavelengths—over these three observations were used to probe the density and composition of the absorbing material around the star.
The team found that the dips in both optical and X-ray light are caused by dense gas obscuring the star's light. The observation in 2017 showed strong emission from iron atoms, indicating that the disk contained at least 10 times more iron than in the 2013 observation during a bright period.
The researchers think the excess iron was created when two planetesimals, or infant planetary bodies, collided. If one or both planetary bodies are made partly of iron, their smash-up could release a large amount of iron into the star's disk and temporarily obscure its light as the material falls into the star.
This discovery gives insight into the processes affecting the development of infant planets. Undoubtedly, astronomers will continue to study this fascinating object with Chandra and other telescopes.

Twelve New Moons Discovered Around Jupiter, and One of Them is Pretty Odd! - The gas giant Jupiter, which was named in honor of the king of the gods in the Roman pantheon, has always lived up to its name. In addition to being the largest planet in the Solar System – with two and a half times the mass of all the other planets combined – it also has an incredibly powerful magnetic field and the most intense storms of any planet in the Solar System. What’s more, it is home to some of the large...

Western political, intelligence and journalistic community erupted in understandably and justly very negative coverage of Donald Trump’s disastrous performance at the press conference in Helsinki. Former CIA director John Brennan even called it “nothing short of treasonous “. As the shocked world media kept all eyes on #Trump, they overlooked a rare moment of Vladimir #Putin speaking the truth, albeit inadvertently

Anyone who has read the horrible stories of what doctors in Europe are doing and have done to parents and children with state run medicine (socialized medicine)would cringe at the thought of socialized medicine in this country as described by Sanders in this speech and that broad from new York that want socialism in this country....

Q&A session with Linus Torvalds: Why is Linux not competitive on desktop?
I think Linus does touch on one of the biggest reasons for why the situation is the way it is, and I certainly know that is how Windows managed to initially dominate the market = pre-installs on purchased machines. In the early years of Windows you had a buy Windows on every desktop machine you bought. Point is the user would have to reinstall the OS and just as with mobile phones, users really don't want to do that.
So the key really is pre-installed desktop OS.... like the Chromebook. As more apps go browser-based and interoperable we can expect Chromebooks to get more and more popular.
Gaming is going to be an exception for longer but mainly because some games are still only produced for Windows. That happens not because Linux can't handle the game, it is pure market economics in that the Windows market is still so big. Game producers go where the numbers are. If the number change over time, so will the game manufacturers.
So ironic that Linus originally created Linux for the desktop and it is the only platform in which it does not dominate! But no matter, everyone has the freedom of choice hence why I only buy computer components and need not pay for a Windows OS that I'm not going to use.
