About Great Hornbill:

• The great hornbill, also known as the concave-casqued hornbill, great Indian hornbill, or great pied hornbill, is a large bird and one of the larger members of the hornbill family.
• Scientific Name: Buceros bicornis
• Distribution:
• It is found in the Indian subcontinent and Southeast Asia.
• In the subcontinent they are found in a few forest areas in the Western Ghats and in the forests along the Himalayas.
• Habitat: Great hornbills reside in wet evergreen and deciduous old-growth forests at elevations of 600 to 2000 meters (1968.5 to 6561 feet). For nesting, they prefer trees that tower above the canopy level.
• Features:
  • They are fairly large, ranging from 95 to 120 cm in length and featuring a wingspan of 151 to 178 cm. On average, they weigh 3 kg.
  • They are vividly colored and easily recognizable. The body, head, and wings are primarily black; the abdomen and neck are white. The tail is white and is crossed by a subterminal black band.
  • A preen gland near the tail secretes tinted oil, which is spread across the feathers by the bird during grooming. This may give the bill, neck, casque, and tail and wing feathers coloration varying from yellow to red.
  • The most recognizable feature of hornbills is the casque, which is a hollow structure located on top of the bill. It may be used by males to fight with other males and attract females.
  • Like many other hornbills, these birds have prominent eyelashes.
  • Males and females are similar except that the irises of males are red while those of females are white, and males have slightly larger bills and casques.
  • It is predominantly frugivorous, but is an opportunist and will prey on small mammals, reptiles, and birds.
• Conservation Status:
  • IUCN Red List: Vulnerable.

About Vera C Rubin Observatory:

• It is located 8,684 feet above sea level atop the Cerro Pachónmountain in the Chilean Andes.
• Cerro Pachón was selected as the site for Rubin Observatory because it’s an excellent place to conduct high-quality astronomical and astrophysical science.
• It is named after American astronomer Vera C Rubin, who provided evidence about dark matter for the first time in the 1970s
• It is partnered with the S. Department of Energy (DOE) and National Science Foundation (NSF).
• This observatory will provide comprehensive images of the night sky unlike anything astronomers have seen before.
• It will constantly scan the sky of the southern hemisphere for 10 years, gathering 20 terabytes of astronomical data each night.
• The observatory’s software will automatically compare new images with older ones and generate an estimated 10 million alerts per night for each change detected in the sky.
• The centrepiece of the observatory is the Simonyi Survey Telescope. This device is unique for three main reasons.
  • Wide Field View: Astronomers typically use the size of the visible surface of the full Moon to describe a telescope’s field of view. The Hubble Space Telescope observes around 1% of the full Moon’s disc, and the James Webb Space Telescope around 75% — using such telescopes is like looking into space through a straw.
  • Largest Digital Camera: The telescope has the world's largest digital camera, which is the size of a small car, weighs 2,800 kg, and boasts a staggering resolution of 3,200 megapixels.
  • Rapid Movement: The Simonyi Survey Telescope is the fastest-slewing telescope in the world, and takes just five seconds to move and settle from one target to another. This speed is due to the telescope’s compact structure (owing to the three-mirror design), and its mount which floats on a film of oil.
• The observatory will also play a crucial role in expanding our knowledge about the nature of dark matter and dark energy.
• While galaxies, stars, and planets make up 5% of the universe, dark energy makes up about 68%, and dark matter about 27%.

About Nyangai Island:

• It is a small island off the coast of Sierra Leone.
• It is one of a cluster of islands that make up the Turtle Islands archipelago. 
• It is low-lying and situated off a part of the coastline subject to strong currents. As such, they have always been vulnerable to erosion. 
• In less than 10 years, the island has lost two-thirds of its surface area, and now measures only about 200 metres long and 100 metres wide (approximately 650 by 330 feet).
• The island has traditionally been a crossroads for trade, agriculture, fishing and maritime transport in addition to a tourist spot, particularly for its ruins dating back to the slave trade.

Key Facts about Sierra Leone

• It is a tropical country in West Africa, on the Atlantic coast.
• Borders: It is bordered on the north and east by Guinea, on the south by Liberia, and on the west by the Atlantic Ocean.
• Geography: The nation is largely made up of lightly wooded hills with a concentration of mangrove swamps along the coast. 
• Rivers: Some of the major ones include the Rokel River, Taia River, Moa River, and Sewa River.

About Miniature Plasma Loops:

• These miniature loops are about 3,000–4,000 kilometers long and have a width of less than 100 kilometers.
• These are so small and short-lived, that they have stayed hidden until now.
• They hold clues to one of the Sun’s deepest mysteries --how it stores and unleashes magnetic energy.
• They offer a new window into how magnetic energy is stored and released in the solar atmosphere on small scales.
• Among the most intriguing features of the Sun’s outer layer are coronal loops, arc-like beautiful structures of hot plasma that glow at a temperature over a million degrees.
• While these large loops in the solar corona, or outer atmosphere, have long been studied, scientists are now also paying attention to miniature counterparts of these loops.
• This makes them challenging to study, as they stay hidden in the lower layers of the Sun's atmosphere and are mostly unresolved by earlier telescopes.

About Magnetometer:

• A magnetometer is a passive instrument that measures changes in the Earth’s magnetic field.
• The most promising methods for magnetic field measurement are based on detecting polarization rotation of a probe light passing through alkali atoms in a very weak magnetic field.
• Magnetometers based on this method, referred to as Optically pumped atomic magnetometers (OPAMs) and Spin Exchange Relaxation Free (SERF)
• Typically have high sensitivity but demand sophisticated magnetic shielding and have a lower dynamic range.
• Magnetometers are useful devices with applications in areas ranging from fundamental physics to medical imaging and navigation.

What is Raman-Driven Spin Noise Spectroscopy (RDSNS)?

• It uses laser light to listen to the tiny quantum jitters of Rubidium atoms.
• These jittery movements, called spin noise, are random fluctuations in the spin of atoms—fundamental quantum properties like tiny bar magnets.
• When exposed to a magnetic field, the pattern of this spin noise shifts in predictable ways. By shining lasers and analyzing the noise, researchers can accurately measure the magnetic field without touching or disturbing the atoms. 
• RDSNS enhances the dynamic range considerably without significant loss of sensitivity.
• This method could transform the way we measure magnetic fields—making the process faster, portable and precise even in noisy, real-world environments.
• This method exhibits potential for field-deployable applications of magnetic field measurement with broadband capability and fast time response, extending across various scientific, industrial and exploratory fields.
