These scores are a good deal lower than phones using the latest Snapdragon 855 processor, such as the Galaxy S10, as well as the Snapdragon 845 chipset in the Pixel 3 series. However, it surprisingly beat out the Google Pixel 2 and 2 XL, which scored 146,876 and 110,949 on AnTuTu, respectively.
There may be a few graphically-intensive games that could give the Pixel 3a and 3a XL pause, but so far, my experience has been pleasantly smooth.
The idea is to place two or three satellites in circular orbit around the Earth to observe black holes. The concept goes by the name Event Horizon Imager (EHI). In their new study, the scientists present simulations of what images of the black hole Sagittarius A would look if they were taken by satellites like these.
More than five times as sharp
“There are lots of advantages to using satellites instead of permanent radio telescopes on Earth, as with the Event Horizon Telescope (EHT),” says Freek Roelofs, a PhD candidate at Radboud University and the lead author of the article. “In space, you can make observations at higher radio frequencies, because the frequencies from Earth are filtered out by the atmosphere. The distances between the telescopes in space are also larger. This allows us to take a big step forward. We would be able to take images with a resolution more than five times what is possible with the EHT.”

Nearly 8,000 light-years away from Earth, astronomers have discovered a black hole that keeps rapidly swinging out jets of plasma clouds into space, according to a new study.
The black hole, known as V404 Cygni, doesn’t behave like others. The jets shoot out possibly within minutes of each other and in all different directions. And while the researchers admit that black holes are some of the most extreme objects in the universe, this one is different.
“This is one of the most extraordinary black hole systems I’ve ever come across,” study author James Miller-Jones said in a statement. Miller-Jones is also an associate professor at Curtin University’s International Centre for Radio Astronomy Research.
Last observed in 2015, the black hole is spewing out ‘wobbly’ plasma jets that move so fast they change orientation within minutes.
Some 8,000 light-years from Earth in the Cygnus constellation (“The Swan”), a small black hole weighing just nine times the mass of Earth’s sun is gobbling up a sun-like star. The black hole and its stellar victim are locked together in what astronomers call a binary system and orbit each other once every 6.5 days – with spectacular effects, the National Radio Astronomy Observatory (NRAO) is reporting.
While the black hole may be relatively tiny as far as these celestial objects go – for instance, the supermassive black hole at the heart of the Milky Way galaxy, known as Sagittarius A*, is 4 million times more massive than the sun, per a previous report from The Inquisitr – it does pack a pretty mean punch. Dubbed V404 Cygni, the black hole is continuously siphoning material from its stellar companion, slowly consuming the unfortunate star.
New data from the Hubble Space Telescope confirms that the universe is expanding nine percent more rapidly than theoretical calculations predicted.
Those original calculations were based on data from the early universe, so many scientists suspected that something sped up the works. But the new Hubble data suggests that the universe could be substantially younger than previously believed — perhaps by as much as a billion years, according to the Associated Press.
