Moon Current Affairs - 2020
The Earth is to witness an annular solar eclipse on June 21, 2020. The eclipse is to be the deepest as the moon is to cover 98.8% of the sun.
There are four types of solar eclipses. They are partial solar eclipse, total solar eclipse, hybrid solar eclipse and annual solar eclipse.
- Total Eclipse: The total eclipse occurs when the moon completely obscures the sun
- Annular Eclipse: The eclipse that occurs when the sun and moon are in line with the earth. During this eclipse, the sun appears as a bright ring or an annulus.
- Hybrid Eclipse: This type of eclipse shifts between total and annular eclipse
- Partial Eclipse: This eclipse occurs when the sun and moon are not in line with the moon and the earth.
The eclipse to occur on June 21, 2020 will be visible in many parts of India. The eclipse is to continue for 6 hours. The eclipse is to be visible to states such as Rajasthan, Haryana and Uttarakhand. To the rest of the country, the eclipse is to be partial.

The Bombay High court recently sought report on Environmental Impact Assessment (EIA) of Lonar lake from the National Environmental Engineering Research Institute (NEERI) and GSI (Geographical Survey of India).
The expert team from Geographical Survey of India and NEERI are to examine the findings of glass formation on the surface of the lake.
The Lonar Lake in Maharashtra is an oval shaped lake that was formed by a meteorite hit on the earth around 50,000 years ago. The colour of the lake had recently turned pink. The area around the lake is an eco-sensitive zone as it consists of the Ejecta Blanket that is made up of the same material as that found on the moon.
The lake is a National Geo-Heritage monument.
National Geo-Heritage Monument
The National Geo-Heritage Monument are areas of national importance and are notified under Geological Survey of India for protection, maintenance, promotion and enhancement of geotourism. There are 34 National Geo-Heritage Monuments in India. The respective state governments are responsible to protect these sites.
Why did the lake turn pink?
Experts believe that the Lonar lake turned pink due to increased salinity in the water and also due to the presence of algae. The amount of water in the lake has reduced thereby increasing its salinity and turning the lake pink.
