What is urban heat island effect?
The urban heat island is a phenomenon when the heat gets trapped near the earth’s surface as a result of a decline in green cover, rapid urbanisation, energy-intensive activities, and concrete structures.
,,,,,,,,,,,,,,,,,Urban heat islands can have worse air and water quality than their rural neighbours. UHIs often have lower air quality because there are more pollutants (waste products from vehicles, industry, and people) being pumped into the air. These pollutants are blocked from scattering and becoming less toxic by the urban landscape: buildings, roads, sidewalks, and parking lots. Water quality also suffers. When warm water from the UHI ends up flowing into local streams, it stresses the native species that have adapted to life in a cooler aquatic environment.

,,,,,,,,,,,,,,,,,,,,,,,,The urban heat island effect is so strong in Delhi, the largest city in the region, that it saw 50% less fog than surrounding areas. In Delhi, the heat island effect also appears to be suppressing the very formation of fog. Scientists found that while areas outside Delhi have seen a 20 per cent increase in fog in the period 2012-2016 compared with 2000-2004, Delhi itself did not see an increase.
,,,,,,,,,,,,,,,,,,SPARCS is a new NASA-funded space telescope and will be launched in 2021. The mission, including spacecraft design, integration and resulting science, is led by Arizona State University’s School of Earth and Space Exploration (SESE).
The stars that SPARCS will focus on are small, dim, and cool by comparison to the Sun. Having less than half the Sun’s size and temperature, they shine with barely one per cent its brightness.
The heart of the SPARCS spacecraft will be a telescope with a diameter of nine centimetres plus a camera with two ultraviolet-sensitive detectors to be developed by NASA’s Jet Propulsion Laboratory.
Both the telescope and camera will be optimised for observations using ultraviolet light, which strongly affects the planet’s atmosphere and its potential to harbour life on the surface.

,,,,,,,,,,,,,,,,,,India to rename Teen Murti Chowk as ‘Teen Murti Haifa Chowk’ for PM Netanyahu visit
Prime Minister Modi had indicated at the renaming during his visit to Haifa last year where he unveiled a plaque commemorating the leadership of Major Dalpat Singh who led the successful operation. 2018 marks a centenary of the end of the World War I and the Battle of Haifa.
Teen Murti War Memorial has three life-size bronze statues representing the Hyderabad, Jodhpur and Mysore Lancers who participated in the Battle of Haifa for the 15 Imperial Service Cavalry Brigade. The victorious operation by the Indian soldiers carried out on 23 September 1918 targeted the fortification of the city of Haifa which was then controlled by a joint Ottoman, German and Austro-Hungarian force. The Indian soldiers fighting for the Allied Powers, captured Haifa and cleared a crucial route for the Allies. A total of 44 Indian soldiers from the three princely states died during the liberation of Haifa.
However, there was some confusion in the naming process as initial photographs from the venue suggested that both the memorial as well as the Teen Murti Marg which radiates from the roundabout will be renamed.
,,,,,,,,,,,indian harvest festivals
Various festivals across the nation:
Makar Sankranti: The festival of Makar Sankranti is being celebrated today when the Sun enters the Makar zodiac and the days begin to lengthen compared to nights.
Pongal: In South India and particularly in Tamil Nadu, it’s the festival of Pongal which is being celebrated over 4 days at harvest time.
Magha Bihu: In Assam and many parts of the North East, the festival of Magha Bihu is celebrated. It sees the first harvest of the season being offered to the gods along with prayers for peace and prosperity. People in Assam celebrate this festival wearing colourful and bright clothes.
Uttarayan: Gujarat celebrates it in the form of the convivial kite festival of Uttarayan.
Maghi: In Punjab, Makar Sankranti is celebrated as Maghi. Bathing in a river in the early hours on Maghi is important.
Saaji: In Shimla District of Himachal Pradesh, Makara Sankranti is known as Magha Saaji. Saaji is the Pahari word for Sakranti, start of the new month. Hence this day marks the start of the month of Magha.
