Osva Scientists Identify Source of Galaxy-Sized Stream of Gas
This Hubble Space Telescope snapshot reveals an unusual ldquo see-through rdquo galaxy. The giant cosmic cotton ball is so diffuse and its ancient stars so spread out that distant galaxies in the background can be seen through it. Called an ultra-diffuse galaxy, this galactic oddball is almost as wide as the Milky Way, but it contains only 1/200th the number of stars as our galaxy. The ghostly galaxy doesn rsquo t appear to have a noticeable central region, spiral arms, or a disk. Researchers calculated a more accurate distance to the gal stanley shop axy, named NGC 1052-DF2, or DF2, by using Hubble to adidas samba femme observe about 5,400 aging red giant stars. Red giant stars all reach the same peak brightness, so they are reliable yardsticks to measure distances to galaxies. The research team estimates that DF2 is 72 million light-years from Earth. They say the dis stanley thermo tance measurement solidifies their claim that DF2 lacks dark matter, the invisible glue that makes up the bulk of the universe rsquo s contents.

Google and Microsoft have just disclosed another CPU flawKnown simply as ldquo Speculative Store yeezys Bypass rdquo (Variant 4), this is the latest CPU flaw found by Google and Microsoft, and Intel has just released a statement explaining what the variant is and how you can protect yourself. Variant 4 uses speculative execution to potentially expose certain kinds of data through a side channel, allowing an attack nike 97 er to read older memory in a CPU rsquo s stack or other memory locations.As listed out in the US-CERT alert, this vulnerability could allow less privileged code (and hence an attacker) to read arbitrary privileged data and run older comma all stars nds speculatively, resulting in cache allocations that could be used to extract data by standard side-channel methods.Intel says they rsquo ve already delivered microcode updates for Speculative Store Bypass in Beta to OEMs, and they expect them to be more broadly released into production BIOS and software updates over the coming weeks.
