Magellanic Bridge

August 1, 2026

Magellanic Bridge Latest News

A team led by Inter-University Centre for Astronomy and Astrophysics (IUCAA) team has discovered the first known system of its kind in the Magellanic Bridge by using eROSITA X-ray telescope.

About Magellanic Bridge

It is a stream of stars and gas created by the close encounter of two nearby galaxies, the Large and Small Magellanic Clouds.
It is mainly a gaseous feature connecting the two galaxies, with a small fraction of in situ formed young stars.
The MB is believed to be composed of tidally stripped material from the SMC during its last encounter with the LMC, approximately 200-300 Myr ago.
Significance
- Magellanic Bridge can help us understand how close encounters between galaxies influence the way binary stars form, evolve and survive.
- Researchers will be able to compare stellar evolution in the Bridge with that in the Large and Small Magellanic Clouds, and gain a clearer picture of how interactions between neighbouring galaxies shape their stars over time.

Key Features of eROSITA X-ray Telescope

eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is a wide-field X-ray telescope on-board the Russian-German "Spectrum-Roentgen-Gamma" (SRG) observatory.
It was developed under the leadership of the Max-Planck Institute for extraterrestrial Physics (MPE) in Germany (DE).
eROSITA is a sensitive X-ray telescope capable of delivering deep, sharp images over very large areas of the sky in the energy range ~0.2-8 keV.
It is placed in a halo orbit around the L2 point
It has been performing an all-sky survey, in which the whole celestial sphere is mapped once every six months.

Cholera

August 1, 2026

Cholera Latest News

While cholera has nearly disappeared from wealthy countries, it remains one of the world’s deadliest waterborne diseases in places where clean water and basic healthcare are unreliable.

About Cholera

Cholera is a disease that is caused by the bacteria Vibrio cholerae.
Cholera can cause serious diarrhea and dehydration. Without treatment, the disease can be fatal within hours, even in people who are healthy.
Transmission:
- People can get cholera by drinking water or eating food contaminated with cholera bacteria.
- The disease is most common in places with poor sanitation, crowding, war, and famine. Cholera outbreaks are more common in warm climates.
- Cholera bacteria also can live in brackish (slightly salty) and coastal waters. Eating raw shellfish like shrimp and crab can be a source of cholera.
- Cholera is not likely to spread from person to person or from casual contact with someone with cholera.
- It is often predictable and preventable. It can ultimately be eliminated where access to clean water and sanitation facilities, as well as good hygiene practices, are ensured and sustained for the whole population.
Symptoms:
- Most people infected with V. cholerae do not develop symptoms but can spread the bacteria through their faeces for 1–10 days.
- Symptoms appear 12 hours to 5 days after infection.
- Most people with the disease have mild or moderate symptoms.
- A minority of patients develop severe acute watery diarrhoea and life-threatening dehydration.
Treatment:
- Treatment for cholera includes drinking plenty of fluids or getting intravenous fluids to prevent dehydration.
- Healthcare providers also sometimes prescribe antibiotics like doxycycline, erythromycin, or azithromycin to help you feel better.
- Providers also treat kids between the ages of 6 months and 5 years with zinc supplements.
- Antidiarrheal medicines aren’t recommended for cholera and could make symptoms worse.

Who are Nihang Sikhs?

August 1, 2026

About Nihang Sikhs

Nihangs, or Nihang Singhs, originally known as Akalis or Akali Nihangs, are a distinct warrior order within the Sikh community, known for their martial traditions, unique attire, and adherence to a specific code of conduct.
They have a rich history dating back to the times of Guru Gobind Singh, the 10th Sikh Guru.
They are easily recognizable by their distinctive blue attire, which includes blue robes, high turbans adorned with steel quoits (chakrams), and they often carry traditional weapons like swords, spears, and daggers.
They are highly skilled in Gatka martial arts and have historically served as a dedicated and elite force to protect Sikh shrines and communities.
Nihangs had a major role in defending the Sikh Panth after the fall of the first Sikh rule (1710-15), when Mughal governors were killing Sikhs, and during the onslaught of Afghan invader Ahmed Shah Durrani (1748-65).
Current Status:
- Nihangs are today divided into several groups, each with its own “chhaoni” (cantonment), but are loosely organised into two “dals” (forces)—Buddha Dal and Taruna Dal, names initially given to the two sections into which the ‘Khalsa’ army was divided in 1733.
- The Buddha Dal has its headquarters at Talvandi Sabo, in Bathinda district, while the principal cantonment of the Taruna Dal Nihangs is at Baba Bakala in Amritsar district.
- Anandpur Sahib, the birthplace of the Khalsa, remains the main centre of Nihang gatherings.
- They assemble there in the thousands in March every year to celebrate Hola Mahalla, a Sikh festival introduced by Guru Gobind Singh.
- On that occasion, they hold tournaments of military skills, including mock battles.

Q1) Who was Guru Gobind Singh?

He was the 10th and last human Guru of the Sikhs. Born as Gobind Rai on December 22, 1666, in Patna, Bihar, Guru Gobind Singh was the son of the ninth Guru of Sikhism, Guru Teg Bahadur. He became the spiritual and temporal leader of the Sikhs on November 11, 1675, at the age of nine, following the martyrdom of his father, Guru Tegh Bahadur, at the hands of the Mughal emperor Aurangzeb in 1675. He was renowned as a warrior, a poet, and a prophet. He is fondly remembered by Sikhs as a defender of the faith and a champion of equality and justice.Among his notable contributions to Sikhism are founding the Sikh warrior community called Khalsa in 1699.
