Scary Barbie

Scientists discovered a supermassive black hole and have named it ‘Scary Barbie,’ after a beloved children’s character.

  • Scary Barbie is a supermassive black hole that is devouring a star with a thousand times the brightness of a supernova.
  • Scary Barbie was first observed in 2020 and it was named ZTF20abrbeie.
  • It is one of the most luminous, energetic, long-lasting transient objects in the sky.
  • But it is also extremely far away and in a somewhat neglected corner of the sky.
  • The researchers discovered it using an AI engine called REFITT (Recommender Engine For Intelligent Transient Tracking).
  • The AI engine looks through observations from many different telescopes around the world.

Spaghettification - It is a process in which the forces around a black hole, called tidal disruption, pull other objects apart.

Ekatha Harbour

Defence Minister of India and his Maldivian counterpart laid the foundation stone for the Coast Guard ‘Ekatha Harbour’.

  • ‘Ekatha Harbour’ is a harbour for the Coast Guard of the Maldives National Defence Force (MNDF).
  • It is located at Sifavaru in Uthuru Thila Falhu (UTF) atoll.
  • The UTF Harbour Project is among the biggest Indian grant-in-aid projects in Maldives.
  • At UTF atoll India is assisting in construction of a naval dockyard.
  • India recently gifted a fast patrol vessel to Maldives Coast Guard and the ship was commissioned as CGS Huravee.
  • These were in line with India’s vision of Security and Growth for All in the Region (SAGAR).
  • India-Maldives - Maldives is among India’s key maritime neighbours in the Indian Ocean Region.

Zoonomia Project

The ambitious genome project, Zoonomia, shows how humans fit with other mammals.

  • The Zoonomia Project is an international collaboration to discover the genomic basis of shared and specialized traits in mammals.
  • A team of scientists from Uppsala University and Broad Institute started the project in 2015 and later joined by researchers across the world.
  • Zoonomia project compares the genomes of 240 mammal species as well as people to trace evolutionary changes spanning 100 million years.
  • It aims at pinpointing genetic traits widely shared and those more uniquely human.
  • Key Findings - The project identified parts of the genome functionally important in people and other mammals.
  • It showed how certain mutations can cause disease.
  • The project revealed the genetics of uncommon mammalian traits like hibernation and showed how the sense of smell varies widely.
  • Some mammals have a very keen sense of smell like the African savanna elephant while others have almost none like whales and dolphins.
  • Humans have average sense of smell.

  • COP28 President-Designate Sultan Ahmed Al Jaber called on meeting participants to ramp up renewable energy capacity building.
  • He called for a tripling of renewable energy capacity by 2030 followed by a doubling in 2040, but his address focused on reducing fossil fuel ‘emissions’.

Petersberg Climate Dialogue

  • The first Petersberg Climate Dialogue took place in 2010 at Petersberg hill near Bonn city, where the UNFCCC is headquartered.
  • In subsequent years, the Petersberg Climate Dialogue conference was held in Berlin.
  • Initiated by former German Chancellor Angela Merkel after unsuccessful negotiations at the 2009 United Nations Climate Change Conference in Copenhagen (COP15)
  • It is aimed at improving communication between leaders and environmental ministers.
  • Global Stocktake - It is a periodic review of global climate action which aims to assess whether current efforts will enable us to reach the objectives set out in the Paris Agreement.
  • 2023 is the year for the Global Stocktake and also the first Global Stocktake year since the Paris Agreement was signed in 2015.
  • The report is set to be released in September of 2023.
