The Indian Space Research Organization (ISRO) has chosen the first day of the year to look for black holes. On Monday (January 1) at 9:10 am local time, the Indian space research organization ISRO's satellite Exposat went into space. EXPOSAT started its journey on the back of the Polar Satellite Launch Vehicle or PSLV from the Satish Dhawan Space Research Center in Sriharikota. This is PSLV's 60th space flight. News BBC.


It is India's first X-ray polarimeter satellite, second in the world. Only NASA has sent such an artificial satellite into space before.
ISRO announced this success in a social media post. Currently, Exposat is placed in an orbit 650 km away from Earth.


ISRO Chairman S Somnath said, I got another success in PSLV. Exposat satellites are placed in fixed orbits. More exciting times await us. The year has just begun. There are many more projects this year. 2024 is the year of Gaganyan.


This satellite will search and observe black holes in space. Also on Exposat's list of the 50 brightest energy sources observed. Scientists will also study neutron stars in space through this artificial satellite.


The life of this artificial satellite in space is five years. Exposat will orbit in low Earth orbit. Its maximum height from the ground will be 500 to 700 km. EXPOSAT has two payloads – POLEX (Polarimeter Instrument in X-rays) and XSPECT (X-ray Spectroscopy and Timing). Raman Research Institute and UR Rao Satellite Center jointly developed the payload.


EXPOSAT will search for X-ray sources in space. Through this, ISRO is going to get a new direction in the research about black holes. This satellite will gather information about the presence, detection, source, etc. of black holes.


Black holes and neutron stars are created when a star 'dies' in space. Black hole has the highest gravitational force in the universe.
In addition, many neutron particles come together in a dark density and the name of the star is neutron star. Such stars are very small in size. The radius of a neutron star is generally not more than 30 km. Exposat will also observe those stars. ISRO has spent 250 crore rupees on this mission.

India has approved the export of 99 thousand 150 tons of onions to 6 countries including Bangladesh. Other countries are - United Arab Emirates, Bhutan, Bahrain, Mauritius and Sri Lanka.

This information was given on the website of the Government of India on Saturday (April 27).

It said onion exports were banned to ensure domestic supply due to lower kharif and rabi seasons in the country in 2023-24 compared to the previous year. This increases the demand in the international market. Indian agency National Cooperation Exports Limited (NCEL) exports onions to these countries. They procure onions from internal sources through e-platform at lowest price (L1). Then, on a 100% advance payment basis, the rates are negotiated and supplied to the agencies or government-designated agencies in the destination countries.

NCEL fixes the prices with the buyers taking into consideration the prices of the countries where onion is bought, international and domestic prices. Now the quotas are allocated according to the demand of the countries where onion export is allowed.

Maharashtra is the largest onion producer in India. They are the largest supplier of onions to NCEL for export.

Earlier, Bangladesh had sent a formal letter to the Indian government to allow the export of certain quantities of onion to reduce the price of onion in the country's market during the holy month of Ramadan.

In addition, the country's government has allowed the export of additional 2000 metric tons of white onion. These onions are mainly exported to Middle East and some European countries. Due to the high production cost of white onion, its price is relatively high.

India is the world's largest onion exporter. The country's government had imposed a ban on onion exports till March 31, 2024 in December last year to maintain supply in the domestic market. Later it was extended indefinitely. The new decision to export onions is good news for India's friendly countries.

US universities have erupted in protest over Israel's military operation in the Palestinian-besieged Gaza. This pro-Palestinian movement is being suppressed even after mass arrests. Rather, as the days go by, the protests are spreading.

The news agency Reuters reported that police made mass arrests at Atlanta's Emory University amid protests. A graduation ceremony at the University of Southern California was canceled due to the protests.

Emory University officials said protesters not affiliated with the college entered campus grounds early Thursday morning. When they refused to leave, the police used chemical spray to disperse them.

According to CBS News, about 108 people were arrested at Emerson College in the city on Wednesday night local time. Earlier in the evening, 93 people were taken into police custody from the University of Southern California in Los Angeles, California.

Anti-Israel protests have spread to dozens of US universities within a week of starting at New York's Columbia University.

Meanwhile, a clash between protesters and police took place at the University of Texas in Austin, Texas. Later, authorities said that 34 people were arrested from there. These new arrests came after massive arrests of protesters at Columbia, Yale and New York universities.

Students gathered Wednesday (April 24) to protest at the University of Southern California's Alumni Park. At this time they were stopped by the riot police. Protesters were told to leave within 10 minutes by an announcement from a police helicopter. However, the students who remained at the scene were arrested for trespassing.

The protests at the University of Southern California were reportedly peaceful at first. Later the tension spread with the presence of the police. Protesters threw water bottles at the police when they tried to arrest a woman. At this time, they kept shouting slogans - 'Let him go'. Besides, they surrounded the police officers and shouted slogans like 'I want the liberation of Palestine'.

It should be noted that on October 7, the Palestinian independence organization Hamas entered Israeli territory and carried out an ambush. 1200 people were killed. Because of this, since that day, the Israeli forces continue to attack Gaza indiscriminately. 34 thousand 305 Palestinians were killed in the Gaza Strip in the attack that lasted for more than six months. Apart from this, there is a severe humanitarian crisis due to lack of food, water and medical equipment.
