1 hour progress. Actually I want to start making a high-detailed drawing, but I stopped drawing almost half-year and now need to start from rookie back and I got lots of thing to do like study, final and etc. So wish me luck 😫👌
A Mesmerizing Model of Monster Black Holes
Just about every galaxy the size of our Milky Way (or bigger) has a supermassive black hole at its center. These objects are ginormous — hundreds of thousands to billions of times the mass of the Sun! Now, we know galaxies merge from time to time, so it follows that some of their black holes should combine too. But we haven’t seen a collision like that yet, and we don’t know exactly what it would look like.
A new simulation created on the Blue Waters supercomputer — which can do 13 quadrillion calculations per second, 3 million times faster than the average laptop — is helping scientists understand what kind of light would be produced by the gas around these systems as they spiral toward a merger.
The new simulation shows most of the light produced around these two black holes is UV or X-ray light. We can’t see those wavelengths with our own eyes, but many telescopes can. Models like this could tell the scientists what to look for.
You may have spotted the blank circular region between the two black holes. No, that’s not a third black hole. It’s a spot that wasn’t modeled in this version of the simulation. Future models will include the glowing gas passing between the black holes in that region, but the researchers need more processing power. The current version already required 46 days!
The supermassive black holes have some pretty nifty effects on the light created by the gas in the system. If you view the simulation from the side, you can see that their gravity bends light like a lens. When the black holes are lined up, you even get a double lens!
But what would the view be like from between two black holes? In the 360-degree video above, the system’s gas has been removed and the Gaia star catalog has been added to the background. If you watch the video in the YouTube app on your phone, you can moved the screen around to explore this extreme vista. Learn more about the new simulation here.

Although it looks like a panel painting, this object is actually the upper cover of an Unidentified Himalayan Manuscript that dates from 14th Century. The wooden cover has two distinct sides with a detailed painting of twelve dancing goddesses on one side, and gilded carvings on the other. Although we do not know from exactly where it came, it is likely that it was housed in a library like this one, in the main monastery of Gyantse Monastery, Tsang, Tibet.
The smooth, painted side of the manuscript cover with its delicate painting would actually face inwards, towards the manuscript’s pages. The fact that it was not exposed to the outside may be why the painting is in such good condition while the other, carved side that faces outwards has lost much of its paint and gilding.
In modern times, the smooth surface of the cover had been coated with a layer of wax-like material. This coating was thick in some areas, like areas of paint loss, and thinner in others. Because of its tacky texture the coating had attracted dust and fibers. Matte in some areas and shiny in others, the coating detracted from the intricate details of the composition.
The goal of the conservation treatment therefore, was to remove the dirty, uneven coating without affecting the paint layers. Two techniques helped determine how this could be done in a safe and even manner. First, a small sample was taken to create a cross section that could be analyzed under magnification in different types of light. This showed how many layers the painting was composed of and the coatings on top of them. Removing the topmost layer, the layer that looks clear/bluish in the UV photo micrograph, above the brighter white layer, was made the priority.
This was the layer that had attracted the disfiguring dust and once removed with the a cotton swab it appears yellow/brown.
Next, once treatment had begun, an ultraviolet reflected photograph (UVR) was taken to show where this layer had been removed.
In the UVR photograph, the remaining coating shows up darker and can be seen on the right side of the panel. This type of photography will help us to determine that the coating is removed evenly and completely.

What is creativity, and can it be enhanced—safely—in a person who needs a boost of imagination? Georgetown experts debate the growing use of electrical devices that stimulate brain tissue, and conclude there is potential value in the technique. However, use of these machines also raises neuro-ethical, legal, and social issues that must now be addressed.
In an article published today in Creativity Research Journal, Georgetown researchers say that the clearest problematic issues with using transcranial electrical stimulation (tES) to improve various forms of creative cognition relate to the use of the procedure in a child’s brain. This scenario is increasingly likely because tES devices are not just in clinical use for some neurological disorders but are widely being sold direct to consumer (DTC), and are being made in a do-it-yourself (DIY) fashion, researchers say.

Cassini's Final View of Titan's Northern Lakes and Seas
NASA - Cassini Mission to Saturn patch. September 14, 2018 During NASA’s Cassini mission’s final distant encounter with Saturn’s giant moon Titan, the spacecraft captured the enigmatic moon’s north polar landscape of lakes and seas, which are filled with liquid methane and ethane.
Image above: During NASA’s Cassini mission’s final distant encounter with Saturn’s giant moon Titan, the spacecraft captured this view of the enigmatic moon’s north polar landscape of lakes and seas, which are filled with liquid methane and ethane. Image Credits: NASA/JPL-Caltech/SSI. They were captured on Sept. 11, 2017. Four days later, Cassini was deliberately plunged into the atmosphere of Saturn. Punga Mare (240 miles, or 390 kilometers, across) is seen just above the center of the mosaic, with Ligeia Mare (300 miles, or 500 kilometers, wide) below center and the vast Kraken Mare stretching off 730 miles (1,200 kilometers) to the left of the mosaic. Titan’s numerous smaller lakes can be seen around the seas and scattered around the right side of the mosaic. Among the ongoing mysteries about Titan is how these lakes are formed. Another mystery at Titan has been the weather. With its dense atmosphere, Titan has a methane cycle much like Earth’s water cycle of evaporation, cloud formation, rainfall, surface runoff into rivers, and collection in lakes and seas. During Titan’s southern summer, Cassini observed cloud activity over the south pole (see PIA06112 and PIA06109). PIA06112: https://www.jpl.nasa.gov/spaceimages/details.php?id=PIA06112 PIA06109: https://www.jpl.nasa.gov/spaceimages/details.php?id=PIA06109 However, typical of observations taken during northern spring and summer, the view here reveals only a few small clouds. They appear as bright features just below the center of the mosaic, including a few above Ligeia Mare. “We expected more symmetry between the southern and northern summer,” said Elizabeth (“Zibi”) Turtle of the Johns Hopkins Applied Physics Lab and the Cassini Imaging Science Subsystem (ISS) team that captured the image. “In fact, atmospheric models predicted summer clouds over the northern latitudes several years ago. So, the fact that they still hadn’t appeared before the end of the mission is telling us something interesting about Titan’s methane cycle and weather.” “Titan is a fascinating place that really teases us with some of its mysteries,” said Turtle. The images in this mosaic were taken with the ISS narrow-angle camera, using a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometers. The view was obtained at a distance of approximately 87,000 miles (140,000 kilometers) from Titan. Image scale is about 0.5 miles (800 meters) per pixel. The image is an orthographic projection centered on 67.19 degrees north latitude, 212.67 degrees west longitude. An orthographic view is most like the view seen by a distant observer looking through a telescope. The Cassini-Huygens mission is a cooperative project of NASA, ESA (European Space Agency) and the Italian Space Agency. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team consists of scientists from the U.S., England, France and Germany. The imaging operations center and team leader are based at the Space Science Institute in Boulder, Colorado.
