So frustrating in a coffee shop to see an interesting line across the eyes and cheeks of someone and want to look closely and maybe sketch and know that they would think, why is that creep staring at me.

Image of a young star in orbit around the black hole at the center of our galaxy. Amazement .

Peribothron

One of the things we tend to do in astronomy is assign different names to things that are basically the same. Take, for example, the term perihelion. The word derives from the Greek peri (close) and helios (Sun) and represents the point at which an orbiting body is closest to the Sun. If a body is orbiting the Earth, then the term is perigee, from geos (Earth). Following the Greek, you get other terms: periareion for Mars, periastron for a star, and so on. There’s also the general term periapsis, but the cool kids like to use specific terms. So what about the closest approach to a black hole? What’s become popular is peribothron, from bothros meaning hole or pit. You’ll likely see the term a bit more because we’re now able to observe bodies reaching peribothron around the black hole in the center of our galaxy. In particular, a body known as G2 has recently passed peribothron at a distance of only 36 light hours from the supermassive black hole, and we’ve image the event with the greatest resolution yet.

Observing the center of our galaxy is difficult because there is a great deal of gas and dust between us and the black hole. We can’t see the region in the visible spectrum, but we can at radio and infrared wavelengths. This allows us to distinguish large bodies such as stars, but smaller stars and other objects are more difficult to distinguish. This has made G2 difficult to study. Because it’s smaller and dimmer than other objects in the region, it’s been difficult to know exactly what it is. There was some indication that it could be a dense cloud of gas, but other evidence pointed to it being a star surrounded by dust.

These latest observations are published in the Astrophysical Journal, and they point toward G2 being a young star rather than a dust cloud. You can see this in the figure above, which shows G2 at various times as it passes peribothron. The images are color coded to indicate the Doppler shift of G2. What it shows is that even at closest approach G2 remains compact, and moves uniformly around the supermassive black hole (located at the + in the figure). If it were merely a dense cloud of gas, we would see some distortion of shape and motion due to the tidal forces of the black hole. This means G2 must be a compact body, and given its temperature and estimated mass, it is likely a young star.

In many ways it’s amazing that we have a term like peribothron. It means we’re now able to observe in detail the orbits of stars around black holes. We’ve come a long way from the astronomy of the early Greeks.

A young star known as G2 has made its closest approach to the supermassive black hole in our galaxy. This has given rise to a term known as peribothron.

If an individual gets wealthy as a minister while his flock contains the poor, that isn't Christ's Church. That's abuse.
 
And they wonder why some folks run the other way....

A favorite song from a favorite Eleni Mandell. I've got a bun in the oven, but I still need lovin', will you be mine tonight? She is an amazing song writer.

This is one of the hugely rare times I disagree in part with Clare. We agree on the education part, but as a quite poor person myself, I know that fast food is seductive, but destroys a budget. The only way to make it is to go with cooking from scratch almost everything with tons of produce. If we tax the junk and use the money to teach people to shop and cook healthy nutritious food, they save money and get healthier. The rich people will buy the crap anyway. The tax won't affect them, it is a progressive tax. That way they can fund efforts to help the poor;) Just sayin'.
 
I am all for the educating of all children on nutrition, I draw the line though with the taxing of fast food in the way that cigarettes and alcohol are done. It would be more helpful too if healthcare were improved. Mental health, nutrional health and if Sport wasn't constantly cut in schools. That better sports facilities be made available to everyone and weight loss programs. 

I am beginning to find Jamie Oliver a little nauseating though quite honestly. The people supporting this action of course are those in a position to buy what they want, eat what they want, go to luxury sport centres and go on holiday at least three times a year.

Jamie Oliver has launched possibly his most daring project to date with a global petition that calls on governments far and wide to provide food education for every child in every school and a push for strident taxes on those who make and promote junk food.

I live in a food desert, that is a great point. There are no grocery stores near me. I manage to walk to grocery stores only because I run out of money and food less than half way into the month if I have to buy from the ubiquitous corner markets/liquor stores. They literally mark up everything 100% over what groceries charge.

Gack. Figuring out someone else's big python program. Not being strongly typed makes me do a lot more searching around to figure out what is going on than I would have to do in C/C++. I have to chase things through multiple function calls to see where it came from, or if it came from some library call chase the other way to see how it is used. Every time I do this I get to be an expert on some area of python libraries and then go back to C++ and the python fades away again.

I like python as well, but it is a lot harder to come into someone's code.

Crazy cool science
Europe and America are building two satellites to study the Sun that will venture closer to the solar inferno than any previous missions.

There's a homey atmosphere with toys to keep young kids occupied. Everyone there was kind. I would recommend it to anyone with a gentle heart.
