The construction of the world’s largest optical telescope has started in northern Chile, which is expected to begin operating in 2024. The Extremely Large Telescope (ELT) is being built by the European Southern Observatory (ESO) and will have a main mirror that is 39m in diameter. The telescope will be positioned on top of Cerro Armazones – a 3046-metre long mountain Chile. It will tackle a wide range of scientific challenges, including probing Earth-like exoplanets for signs of life, studying the nature of dark energy and dark matter, and observing the universe’s early stages to explore humans’ origins.

We know that, in computers transformation of input into output is performed by the ALU unit i.e, the Arithematic and Logical unit that performs all the logical and arithmatical operations in the CPU - Central Processing Unit.

A wildlife management agency sets hunting regulations in most states.

These agencies will have regular meetings where the public can voice their concerns and make suggestions. Hunters wishing to propose changes to the regulations should participate in these meetings or join a hunting organization that interacts with the agency.

Latitude comes first among latitude or longitude.

1. Filing an RTI application with the Delhi government is now just a click away. Delhi became the second state to launch e-RTI portal that will enable citizens to file online Right to Information (RTI). Maharashtra is the first state to launch the online RTI platform.

2. The portal launched recently will enable citizens to file RTI and seek information related to 172 departments of the Delhi government including the office of the CM and his ministers.

3. The e-RTI portal, which has been designed by the National Informatics Centre (NIC), includes filling of application, payment of fees and getting replies online.

In this chemical reaction chlorine change oxidation number from 0 to -1 (reduction) and bromine change oxidation number from -1 to 0 (oxidation).

Chlorine is stronger oxidation reagent than bromine.

In VIIA or group 17 (halogen elements) there are six elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At) and tennessin(Ts).

They have high electronegativity because they have seven valence electrons in their outermost energy level, so they can gain an electron to have the octet rule.  

Going down in the group, element are weaker oxidazing reagent and less reactive.
