The remarkable discovery of the star Earendel by the Hubble Space Telescope in 2022 has been further illuminated by the James Webb Space Telescope.
About Earendel
Earendel is the farthest star ever detected, observed within the first billion years after the big bang.
It’s a massive B-type star, more than twice as hot as the Sun, and a million times more luminous.
The star is part of the SunriseArc galaxy, detectable due to the gravitational lensing
Gravitational lensing is a natural phenomenon where the mass of a massive object bends and magnifies light from a background object.
The massive galaxy cluster WHL0137-08 acts as a “magnifying glass,” allowing telescopes to observe Earendel even though it’s distant.
How was it discovered?
JSWT discovery: The James Webb Space Telescope employed its Near-Infrared Camera (NIRCam) to build upon Hubble’s observations of Earendel.
Star’s Characteristics: The revelations from NIRCam showcase Earendel as a massive B-type star, surpassing our Sun’s heat by over twofold and radiating luminosity a million times greater.
9 Billion Light-Years Away: Situated approximately 12.9 billion light-years from Earth, Earendel holds insights into the early universe’s cosmic evolution.
Gravitational Lensing: Both Webb and Hubble harnessed gravitational lensing—a phenomenon where foreground galaxies magnify distant objects—to detect Earendel, with galaxy cluster WHL0137-08 acting as a cosmic magnifying lens.
Glimpse into it’s Past
Single Point of Light: Due to its immense distance, Earendel appears as a solitary point of light even on Webb’s high-resolution infrared imagery.
Snapshot from 1 Billion Years Post-Big Bang: Although Earendel remains a faint pinpoint, the telescope’s data indicates that we are witnessing the star as it appeared 1 billion years after the Big Bang.
Historic Perspective: This revelation pushes the boundaries of our knowledge, as the previous farthest observed star had been documented around 4 billion years post-Big Bang.
The National Power Committee (NPC) has urged States to contribute their insights towards shaping incentives for both buyers and sellers on the Power High Price Day Ahead Market (HP-DAM) and Surplus Power Portal (PUShP).
This innovative platform, introduced by the Ministry of Power, aims to enhance power availability, optimize utilization, and facilitate efficient power trading.
PUSHp Portal
Concept Launch: The Ministry of Power unveiled the HP-DAM and PUShP to address power scarcity during peak demand periods and to encourage surplus power trading.
Price Flexibility: The platform allows certain sellers to offer power at prices exceeding the ceiling of Rs 12 per unit during peak demand, promoting higher availability.
Surplus Power Indication: Power distribution companies (DISCOMs) can display their surplus power availability on the portal, indicating the block times, days, or months.
Requisition Mechanism: DISCOMs in need of power can requisition the surplus power from the portal, promoting efficient allocation.
Operational Mechanism
Cost Determination: New buyers will pay both variable charges (VC) and fixed costs (FC) as regulated by authorities.
Reassignment Implications: Once power is reassigned, the original beneficiary relinquishes the right to recall power, including the entire FC liability.
Reducing Fixed Costs: This approach alleviates the fixed cost burden on DISCOMs, making power distribution more efficient.
Optimal Capacity Utilization: The platform ensures that all available generation capacity is effectively utilized, mitigating wastage.
Back2Basics: Day Ahead Market
A Day Ahead Market is a platform for trading electricity where delivery occurs within 24 hours from the following day’s midnight.
Electricity is traded in 15-minute time blocks, and prices are determined through auction bidding.
The auction process establishes prices and the quantum of electricity traded, ensuring transparency.
Delimitation, the process of redrawing electoral boundaries to reflect population changes, is a crucial exercise that ensures fair representation and equal distribution of constituencies.
In Assam, the recent delimitation process has garnered attention due to its impact on political dynamics.
