Astronomy Picture of the Day: Comet Iwamoto and the Sombrero Galaxy

Image
Comet Iwamoto and the Sombrero Galaxy Comet Iwamoto (C/2018 Y1) , shows off a pretty, greenish coma at the upper left in this telescopic field of view. Taken on February 4 from the Mount John Observatory , University of Canterbury, the 30 minute long total exposure time shows the comet sweeping quickly across a background of stars and distant galaxies in the constellation Virgo. The long exposure and Iwamoto's rapid motion relative to the stars and galaxies results in the noticeable blurred streak tracing the the comet's bright inner coma. In fact, the streaked coma gives the comet a remarkably similar appearance to Messier 104 at lower right, popularly known as the Sombrero Galaxy. The comet, a visitor to the inner Solar System, is a mere 4 light-minutes a way though, while majestic Messier 104 , a spiral galaxy posing edge-on, is 30 million light-years distant. The first bino

20,000 birds just starved to death off the Dutch coast and no one knows why

Image
Animals Birds are continuing to wash ashore and so far none of the obvious explanations can solve the mystery. Thousands of seabirds have been washing onto the Dutch shoreline for about a month now and no one really knows why. At least, we think it’s been a month. It’s unclear. via Popular Science "http://bit.ly/2GgePw7"

CERT/CC Warns of Vulnerabilities in Marvell Avastar Wireless SoCs

Image
The CERT Coordination Center (CERT/CC) has issued a vulnerability note providing information on a series of security issues impacting Marvell Avastar wireless system on chip (SoC) models. Initially presented by Embedi security researcher Denis Selianin at the ZeroNights conference on November 21-22, 2018, and tracked as  CVE-2019-6496 (CVSS score 8.3), the vulnerability could allow an unauthenticated attacker within Wi-Fi radio range to execute code on a vulnerable system.  The security researcher  discovered multiple vulnerabilities in the Marvell Avastar devices (models 88W8787, 88W8797, 88W8801, and 88W8897), the most important of which is a block pool overflow during Wi-Fi network scan. The vulnerability can be exploited via malformed Wi-Fi packets during identification of available Wi-Fi networks.  "During Wi-Fi network scans, an overflow condition can b
