ZTF Robotic Camera Can Scan Entire Sky with more accuracy



ZTF Robotic Camera Can Scan Entire Sky with more accuracy - When we see sky with our smart phone’s camera we recognize objects in rest. But in reality, all objects are in motion and some materialized phenomena is going on all the time. Suppose if we exchange our smaller camera with a larger one than what will happen? The phenomena or event which take place on space are exploding of stars or comets which seems fairy like heaven. But such phenomenon can be captured with the help of a very large camera which is developed recently by Zwicky Transient Facility (ZTF) at the Palomar Observatory in San Diego.



ZTF Robotic Camera Can Scan Entire Sky with more accuracy

ZTF is a robotic camera placed on 48-inch (1.2 meter) Samuel Oschin Telescope possessing 576-MP camera which can capture a full 47 degrees of the north side sky in a single click. The robotic camera can capture 3750 square degrees of sky image in one hour. The sky all around the earth is nearly 40000 square degrees. The Samuel telescope is scanning skies since the world war II era. So it will take around 3 nights to capture image of entire night sky.

The ZTF System execute those images 2.5 times faster than older installed cameras. It means the researchers can take more pictures and running events compare to slower cameras. The image captured by ZTF camera possess a resolution of about 24k by 24k pixels. The captured images are so big that they are difficult to view on a single screen. Although we need about 72 computer's monitor to watch one of such large resolution image.

The image above shows ZTF’s first captured image on 1 November 2017 at Palomar Observatory. Each such ZTF picture covers a sky area of about 247 times area covered moon. The future vision declare operation of ZTF from early 2018 to the end of 2020 to witness thousands of transient events like exploding of stars, asteroids and planets.

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware - We are familiar with malware attacks on Computer. The hackers infect one or more files and thereby attaining full control on the System. There are millions of victims who had loosen either data or dollars in this respect. In this article we see a System file which is infected by these hackers at first stage. The System file infected by malware at first stage is Task Scheduler Engine (Taskeng.exe). The Task Scheduler Engine is a system file located in C:\Windows\System32 folder. This location is the default location for Taskeng.exe.



The Task Scheduler Engine is responsible for keeping track of tasks set to run at a time predefined by the user of the PC. As said earlier, the original location of this scheduler is C:\Windows\System32 folder. But it is suspicious if the location of scheduler gets change. If it is found in some other folder then it must be infectious. As a result, you constantly get a…

Fix Windows could not find a driver for your network adapter error


A Computer run smoothly with the coordination of Software & Hardware. In the absence of any one it will not run at all. Software being the Master utilizes each hardware attached to the System. And each hardware is operated with the help of Device Drivers installed in it. Operating System (OS) uses these device drivers to control & utilize each hardware when needed. Each hardware connected to the system must have their own Device Driver installed. A device driver is a program to initiate a hardware when required by Operating System.




Suppose, you want your PC to connect to the Network, it can only be possible when your PC has network related Device Driver. These Device Drivers are easily downloaded from Manufacturer Websites. In this article we focus on Network related problem. Suppose, your PC not obtaining Network connectivity. And each time you are getting an error message saying "Windows could not find a d…
