A study conducted by Spanish astronomers showed that the neutron star J0205, which is only 841 years old and has a temperature of 2.3 million degrees Celsius, is considered very cold to an extent that is not compatible with a large number of models that explain the coldness of these cosmic bodies. Unique.

By reviewing what was observed by the XMM Newton and Chandra space telescopes dedicated to discovering neutron stars, the team of Spanish astronomers identified three of them that stand out from the rest.

Dr. Alessio Marino, co-author of the study and a member of the Barcelona Institute of Space Sciences, explained that its temperature is very high on paper, but it is unusually cold for its young age.

This difference is not small, because their temperature reaches at least half the temperature of neutron stars of the same age.

Michaela Ortel, director of research at the National Center for Scientific Research at the Strasbourg Observatory, who specializes in the field of compact objects, noted that the
star is born at a temperature of about 500 billion degrees, and after a few minutes, it drops to less than ten billion degrees, and this temperature drops sharply as it advances.

The age of these stars, one million years.

In the current model, astronomers calculated cooling curves by age, allowing them to be compared to neutron stars.

They determined this age by observing the cloud left over from the original explosion that witnessed the birth of stars.

Their calculations showed that the youngest, J0205, is 841 years old, a date confirmed by historical accounts from medieval sky watchers.

As for the other two, the first is 7,700 years old, and the second is between 2,500 and 5,000 years old, with temperatures of 1.9 and 4.6 million degrees, respectively, that is, at least twice the size of contemporary neutron stars.

The study, published in the journal Nature Astronomy, concluded that for the neutron stars under consideration, these models must include a rapid cooling mechanism, linked to the compositio
n of the star.

The importance of this study is related to basic physics, and lies in the fact that it allows in particular to understand the strong interaction, which is one of the fundamental forces that govern matter in the infinitely small.

Lahij: As part of the Kingdom of Saudi Arabia’s humanitarian efforts, the King Salman Humanitarian Aid and Relief Center (KSrelief) distributed vocational tools to 100 families caring for orphans in Aden and Lahj, Yemen. The initiative was part of a larger project to sponsor orphans and empower their families economically. The project aims to support 440 families by equipping them with essential life and vocational skills, enabling them to establish income-generating businesses in various fields such as electrical installations, mobile-telephone repair, perfume and confectionery production, sewing, and beauty services. The project has already benefited 1,300 orphans across eight Yemeni governorates, contributing to the improvement of their lives and well-being.

This initiative reflects the ongoing relief and humanitarian efforts provided by the Kingdom through KSrelief, which prioritizes caring for orphans and their families, alleviating their suffering, and ensuring a dignified life for them.

Several Palestinians were martyred and injured at dawn Friday when the Israeli occupation forces targeted various areas across Gaza Strip on the 259th day of aggression.

In Khan Yunis in the southern Gaza Strip, three Palestinians were martyred after an Israeli drone shelled Al-Fukhari town. The eastern areas of the city and the vicinity of the European Hospital were subjected to shooting by the occupation forces.

Meanwhile, an Israeli Apache fired bullets towards the eastern area of Rafah city in the southern Gaza Strip, while warplanes launched violent raids on different areas of the city and blew up residential buildings.

In Gaza City, several Palestinians were injured in Israeli air raids that targeted two houses in the Tuffah and Shuja’iyya districts.

In parallel, the occupation artillery fired several shells towards the Zeitoun district southeast of Gaza City, the northern areas of the Nuseirat camp, several areas east of Deir al-Balah, al-Masdar, and the al-Maghazi camp in the central Gaza Strip.

T
he Israeli occupation has continued its brutal aggression on the Gaza Strip since Oct. 7, 2023, leaving more than 37,431 martyred and 85,653 injured in an infinite toll as thousands of victims remain missing under the rubbles.
