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 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.

How do frequent Shut down harm your Computer


How do frequent shut down harm your Computer - We use computers for our personal as well as business purpose and therefore starts and shutdown as we wish.

What does Zero-day vulnerability mean


What does Zero-day vulnerability mean - When a programmer builds a large software with lines of coding, there remain a flaw or hole under which hackers inject malicious codes to manipulate the whole software. Here we will focus on Zero-day vulnerability concept relying mostly on security purpose. A Zero-day vulnerability is a flaw in a software program which cannot be fixed or patched due to unawareness of software developer.




Since the developer has zero days by the time flaws are discovered to protect against the possible attack. If a developer discovers a zero-day vulnerability, it would scramble to correct the flaw and might release update of the software to patch the hole. If in case vulnerability is exploited by the hackers before correction, such attack is called as Zero-day exploit or zero-day attack.
