A new planet discovered by NASA

-

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a new planet recently . It is between the sizes of Mars and Earth and orbits a nearby star. It has been named L 98-59b.

One of TESS’s goals is to build a catalogue of small, rocky planets on short orbits around very bright, nearby stars for atmospheric study.

Apart from L 98-59b, two other worlds orbit the same star. While all three planets’ sizes are known.

“The discovery has a great engineering and scientific accomplishment for TESS. For atmospheric studies of small planets,it is needed to short orbits around bright stars, but such planets are difficult to detect. This system has the potential for fascinating future studies,”.

L 98-59b is around 80% Earth’s size. The two other worlds in the system, L 98-59c and L 98-59d, are respectively around 1.4 and 1.6 times Earth’s size. Their host star, L 98-59, is about one-third the mass of the Sun and lies about 35 light-years away. While L 98-59b is a record for TESS, even smaller planets have been discovered in data collection NASA’s Kepler satellite.

Sattiriya Dance

-
Sattariya Dance origins from Assam. It is devotional dance centered devoted to Lord krishna and related to Vaishnavism.This dance is nurtured and preserved with great commitments by Sattire i.e. Monastries.

The theme of the dance based on Mythological. Now the theme has diversefied a bit from the past. Costumes used for the dance is made of Assamese silk called " Pat Silk". The dance involves in form of Tandava and Lasya. Traditionally this dance is performed by male monks called Bhokots  Initially it was performed by men only but presently performed by both genders as a group form dance.  Recently it is recognised in 2000 by Sangeet Natak Academy. Exponents of the dance form are 1) Bapuram Barbayan Atai, 2) Pradip Chaliha.

The Chola Period marks a distinct and significant period in the art and architecture of India

-
Art and architecture in India reached its climax during Chola period. Chola style of temple architecture was unique due to the emergence of new style called Dravidian style, which was confined mostly to the South India. Chola rulers were wealthy enough to build message palaces with spacious Garden and terraces the use to Mark their victory over other state by building temples that is why number of temples are built during this period Chola style of architecture  This architecture developed under the chola regime  temples surrounded by boundary walls  High entrance gateway gopuram  This follows panchayatn style for principal shine and four subsidiary shrines  The stepped pyramid that rises up is called vimana  Crowning form in octagon its similar to the kalash in nagara style but not spherical  On the main temple the vimana on subsidiary shrine temple there is no vimana  The assembly hall connected with garbgriha using the tunnel that tunnel is called antarala.  T

Interior of the Earth

-
Direct Sources: Mining and deep drilling projects have provided large volume of information through the analysis of materials collected at different depths. Also when  the molten material (magma) is thrown onto the surface of the earth, during volcanic eruption it becomes available for laboratory analysis. •Indirect Sources  Analysis of properties of matter indirectly provides information about the interior. Through the  mining activity, it  is  known that  temperature and  pressure increase  with the  increasing distance from the surface towards the interior in deeper depths. •Also, the density of the material  also  increases  with depth. Knowing the total  thickness  of the earth, scientists have estimated  the values of temperature, pressure and the density of materials  at different depths. Another source of information are the meteors that at times reach the earth. •The material and the structure observed in the meteors are similar  to that of the earth. They are solid bodies dev
