Who has built the 'Solar Ultraviolet Imaging Telescope'?
A)
HAL
B)
DRDO
C)
C-DAC
D)
IUCAA

Correct Answer :   IUCAA


Pune’s Inter-University Center for Astronomy and Astrophysics (IUCAA) has delivered the Solar Ultraviolet Imaging Telescope (SUIT) to the Indian Space Research Organisation (ISRO).

Suit will be launched onboard India's maiden mission to explore the Sun — Aditya L-1 — in the coming months. It is one of the seven instruments being launched outside Earth with the mission to unravel the secrets of the Sun.

WHAT IS SUIT?
* The Solar Ultraviolet Imaging Telescope (Suit), designed by scientists at IUCAA, will study the Sun's ultraviolet (UV) emissions and capture high-resolution images of the Sun's atmosphere, known as the corona, in various UV wavelengths.

* The Sun is one of the most difficult things to study outside Earth due to its high emissions and radiation. With Aditya L-1, India wants to change that and see the star in our Solar System in a new light.

* Suit will enable scientists to explore the dynamic and complex processes occurring in the Sun's outer layers.

* Developed over a span of nearly a decade, Suit will operate in the far and near ultraviolet regions, covering wavelengths of 200-400 nanometers. The instrument will observe the hotter and more dynamic regions of the Sun's atmosphere, such as the transition region and the corona.

* The chromosphere is the layer of the Sun's atmosphere that lies just above the photosphere. The corona is the outermost layer of the Sun's atmosphere.

* The payload, which has had contributions from over 200 scientists, was first announced by Isro in 2012 and work started on its development in 2016.

* Once in space, it will also explore the dynamics of solar flares, sudden, violent outbursts of energy from the Sun. Isro will use Suit to monitor the Sun's activity and provide early warning of potential solar flares and CMEs, study the interaction between the Sun and the Earth's atmosphere, and try to better understand the role of the Sun in climate change.

* Isro had previously received the Visible Emission Line Coronagraph (VELC) to be integrated with Aditya L-1 mission. VELC, developed primarily by IIA, will collect data for solving how the temperature of the corona can reach about a million degrees while the Sun’s surface itself stays just over 6,000 degrees Centigrade.

* The corona has so far only been studied during an eclipse when the disk is covered, and Aditya L-1 is aimed at better understanding the mechanism powering the Sun.


WHAT IS ADITYA L-1 MISSION?
* The Aditya L-1 mission is India's maiden mission to observe the Sun and is expected to launch by August this year. It will be launched nearly 1.5 million kilometers away from Earth to Lagrange Point 1 (L1), a stable point where the gravitational forces between the Earth and the Sun, as well as the centrifugal force of the rotating system, balance out.

* Out of the seven payloads, while four will directly view the Sun, three others will carry out in-situ studies of particles and fields at the Lagrange point L1..
